     INCORPORATION OF SEQUENCE LISTING 
     A computer readable form of the Sequence Listing “29664-P62652US03_SequenceListing.xml” (29,876 bytes), submitted via EFS-WEB and created on Sep. 15, 2022, is herein incorporated by reference. 
     FIELD OF THE DISCLOSURE 
     The compositions and methods disclosed herein relate to a chemical compound known as psilocybin. Furthermore, the compositions and methods disclosed herein relate in particular to aminated forms of psilocybin. 
     BACKGROUND OF THE DISCLOSURE 
     The following paragraphs are provided by way of background to the present disclosure. They are not however an admission that anything discussed therein is prior art or part of the knowledge of a person of skill in the art. 
     The biochemical pathways in the cells of living organisms may be classified as being part of primary metabolism, or as being part of secondary metabolism. Pathways that are part of a cell&#39;s primary metabolism are involved in catabolism for energy production or in anabolism for building block production for the cell. Secondary metabolites, on the other hand, are produced by the cell without having an obvious anabolic or catabolic function. It has long been recognized that secondary metabolites can be useful in many respects, including as therapeutic compounds. 
     Psilocybin, for example, is a secondary metabolite that is naturally produced by certain mushrooms which taxonomically can be classified as belonging the Basidiomycota division of the fungi kingdom. Mushroom species which can produce psilocybin include species belonging to the genus Psilocybe, such as Psilocybe azurescens, Psilocybe semilanceata, Psilocybe serbica, Psilocybe  mexicana , and Psilocybe cyanescens, for example. The interest of the art in psilocybin is well established. Thus, for example, psilocybin is a psychoactive compound and is therefore used as a recreational drug. Furthermore, psilocybin is used as a research tool in behavioral and neuro-imaging studies in psychotic disorders, and has been evaluated for its clinical potential in the treatment of mental health conditions (Daniel, J. et al. Mental Health Clin/, 2017; 7(1): 24-28), including to treat anxiety in terminal cancer patients (Grob, C. et al. Arch. Gen. Psychiatry, 2011, 68(1) 71-78) and to alleviate symptoms of treatment-resistant depression (Cathart-Harris, R. L. et al. Lancet Psychiatry, 2016, 3: 619-627). 
     Although the toxicity of psilocybin is low, adverse side effects, including, for example, panic attacks, paranoia, and psychotic states, sometimes together or individually referred to as “a bad trip”, are not infrequently experienced by recreational psilocybin users. 
     There exists therefore a need in the art for improved psilocybin compounds.

     The term “psilocybin”, refers to a chemical compound having the structure set forth in  FIG.  1   . 
     The term “indole prototype structure” refers to the chemical structure shown in  FIG.  2   . It is noted that specific carbon atoms and a nitrogen atom in the indole prototype structure are numbered. Reference may be made to these carbon and nitrogen numbers herein, for example C 2 , C 4 , N 1 , and so forth. Furthermore, reference may be made to chemical groups attached to the indole prototype structure in accordance with the same numbering, for example R 4  and R 6  reference chemical groups attached to the C 4  and C 6  atom, respectively. In addition, R 3A  and R 3B , in this respect, reference chemical groups extending from the ethyl-amino group extending in turn from the C 3  atom of the prototype indole structure. 
     The term “aminated psilocybin derivative” refers to a psilocybin derivative compound to which an amino group has been bonded to psilocybin or a psilocybin derivative. The nitrogen of the amino group may bear 1-3 substituents (i.e., be a N-substituted amino group). N-substituents can be an alkyl, aryl, acyl, sulfonyl groups or combinations thereof. Reference may be made to specific carbon atoms which may be aminated. For example, a 5-amino-psilocybin derivative refers to a psilocybin derivative in which carbon atom number 5 (as identified in the indole prototype structure) possesses an amino or N-substituted amino group, or, similarly, 7-amino-psilocybin derivative refers to a psilocybin derivative in which carbon atom number 7 (as identified in the indole prototype structure) possess an amino or N-substituted amino group. Thus, for example, aminated psilocybin derivatives include, single amino derivatives, 2-amino, 4-amino, 5-amino, 6-amino, and 7-amino psilocybin derivatives, for example, and multiple amino derivatives, such as, for example, 5,7-di-amino psilocybin derivatives, and 2,5,7-tri-amino psilocybin derivatives. The term aminated psilocybin derivatives further includes chemical compounds having the chemical formula (I):

     It is noted that R′, R″ and R′″ can herein additionally include numerical subscripts, such as 5a, 6b, 7b etc., and be represented, for example, as R′ 5a , R″ 6b  or R′″ 7a , respectively. Where such numerical values are included, they reference chemical entity extending from the amino group extending in turn from the thus numbered C atom of the prototype indole structure. Thus, for example, R′ 5a  is a chemical entity extending from an aminated group attached to the C 5  atom of the indole ring structure, R′ 2a  is a chemical entity extending from an aminated group attached to the C 2  atom of the indole ring structure, and so forth.

     By the term “substantially identical” it is meant that two amino acid sequences preferably are at least 70% identical, and more preferably are at least 85% identical and most preferably at least 95% identical, for example 96%, 97%, 98% or 99% identical. In order to determine the percentage of identity between two amino acid sequences the amino acid sequences of such two sequences are aligned, using for example the alignment method of Needleman and Wunsch (J. Mol. Biol., 1970, 48: 443), as revised by Smith and Waterman (Adv. Appl. Math., 1981, 2: 482) so that the highest order match is obtained between the two sequences and the number of identical amino acids is determined between the two sequences. Methods to calculate the percentage identity between two amino acid sequences are generally art recognized and include, for example, those described by Carillo and Lipton (SIAM J. Applied Math., 1988, 48:1073) and those described in Computational Molecular Biology, Lesk, e.d. Oxford University Press, New York, 1988, Biocomputing: Informatics and Genomics Projects. Generally, computer programs will be employed for such calculations. Computer programs that may be used in this regard include, but are not limited to, GCG (Devereux et al., Nucleic Acids Res., 1984, 12: 387) BLASTP, BLASTN and FASTA (Altschul et al., J. Mol. Biol., 1990:215:403). A particularly preferred method for determining the percentage identity between two polypeptides involves the Clustal W algorithm (Thompson, J D, Higgines, D G and Gibson T J, 1994, Nucleic Acid Res 22(22): 4673-4680 together with the BLOSUM 62 scoring matrix (Henikoff S &amp; Henikoff, J G, 1992, Proc. Natl. Acad. Sci. USA 89: 10915-10919 using a gap opening penalty of 10 and a gap extension penalty of 0.1, so that the highest order match obtained between two sequences wherein at least 50% of the total length of one of the two sequences is involved in the alignment. 
     By “at least moderately stringent hybridization conditions” it is meant that conditions are selected which promote selective hybridization between two complementary nucleic acid molecules in solution. Hybridization may occur to all or a portion of a nucleic acid sequence molecule. The hybridizing portion is typically at least 15 (e.g., 20, 25, 30, 40 or 50) nucleotides in length. Those skilled in the art will recognize that the stability of a nucleic acid duplex, or hybrids, is determined by the Tm, which in sodium containing buffers is a function of the sodium ion concentration and temperature (Tm=81.5° C.-16.6 (Log 10 [Na+])+0.41(% (G+C)−600/I), or similar equation). Accordingly, the parameters in the wash conditions that determine hybrid stability are sodium ion concentration and temperature. In order to identify molecules that are similar, but not identical, to a known nucleic acid molecule a 1% mismatch may be assumed to result in about a 1° C. decrease in Tm, for example if nucleic acid molecules are sought that have a &gt;95% identity, the final wash temperature will be reduced by about 5° C. Based on these considerations those skilled in the art will be able to readily select appropriate hybridization conditions. In preferred embodiments, stringent hybridization conditions are selected. By way of example the following conditions may be employed to achieve stringent hybridization: hybridization at 5×sodium chloride/sodium citrate (SSC)/5×Denhardt&#39;s solution/1.0% SDS at Tm (based on the above equation) −5° C., followed by a wash of 0.2×SSC/0.1% SDS at 60° C. Moderately stringent hybridization conditions include a washing step in 3×SSC at 42° C. It is understood however that equivalent stringencies may be achieved using alternative buffers, salts, and temperatures. Additional guidance regarding hybridization conditions may be found in: Current Protocols in Molecular Biology, John Wiley &amp; Sons, N.Y., 1989, 6.3.1.-6.3.6 and in: Sambrook et al., Molecular Cloning, a Laboratory Manual, Cold Spring Harbor Laboratory Press, 1989, Vol. 3. 
     The term “functional variant”, as used herein in reference to polynucleotides or polypeptides, refers to polynucleotides or polypeptides capable of performing the same function as a noted reference polynucleotide or polypeptide. Thus, for example, a functional variant of the polypeptide set forth in SEQ. ID NO: 2, refers to a polypeptide capable of performing the same function as the polypeptide set forth in SEQ. ID NO: 2. Functional variants include modified a polypeptide wherein, relative to a noted reference polypeptide, the modification includes a substitution, deletion, or addition of one or more amino acids. In some embodiments, substitutions are those that result in a replacement of one amino acid with an amino acid having similar characteristics. Such substitutions include, without limitation (i) glutamic acid and aspartic acid; (i) alanine, serine, and threonine; (iii) isoleucine, leucine, and valine, (iv) asparagine and glutamine, and (v) tryptophan, tyrosine, and phenylalanine. Functional variants further include polypeptides having retained or exhibiting an enhanced psilocybin biosynthetic bioactivity. 
     The term “chimeric”, as used herein in the context of nucleic acids, refers to at least two linked nucleic acids which are not naturally linked. Chimeric nucleic acids include linked nucleic acids of different natural origins. For example, a nucleic acid constituting a microbial promoter linked to a nucleic acid encoding a plant polypeptide is considered chimeric. Chimeric nucleic acids also may comprise nucleic acids of the same natural origin, provided they are not naturally linked. For example a nucleic acid constituting a promoter obtained from a particular cell-type may be linked to a nucleic acid encoding a polypeptide obtained from that same cell-type, but not normally linked to the nucleic acid constituting the promoter. Chimeric nucleic acids also include nucleic acids comprising any naturally occurring nucleic acids linked to any non-naturally occurring nucleic acids. 
     The terms “substantially pure” and “isolated”, as may be used interchangeably herein describe a compound, e.g., a secondary metabolite, psilocybin or a psilocybin derivative, polynucleotide, or a polypeptide, which has been separated from components that naturally accompany it. Typically, a compound is substantially pure when at least 60%, more preferably at least 75%, more preferably at least 90%, 95%, 96%, 97%, or 98%, and most preferably at least 99% of the total material (by volume, by wet or dry weight, or by mole percent or mole fraction) in a sample is the compound of interest. Purity can be measured by any appropriate method, e.g., in the case of polypeptides, by chromatography, gel electrophoresis or HPLC analysis. 
     The term “recovered” as used herein in association with a chemical compound, refers to a more or less pure form of the chemical compound. 
     General Implementation 
     As hereinbefore mentioned, the present disclosure relates to psilocybin derivatives. In particular, the present disclosure provides novel aminated psilocybin derivatives. In general, the herein provided compositions exhibit functional properties which deviate from the functional properties of psilocybin. Thus, for example, the aminated psilocybin derivatives, can exhibit pharmacological properties which deviate from psilocybin. Furthermore, the aminated derivatives may psilocybin derivatives may exhibit physico-chemical properties which differ from psilocybin. Thus, for example, aminated psilocybin derivatives may exhibit superior solubility in a solvent, for example, an aqueous solvent. The aminated psilocybin derivatives in this respect are useful in the formulation of pharmaceutical and recreational drug formulations. Furthermore, the aminated psilocybin compounds of the present disclosure may be used as a feedstock material for deriving further psilocybin derivatives. In one embodiment, the aminated psilocybin derivatives of the present disclosure can conveniently be synthetically produced. The practice of this method avoids the extraction of psilocybin from mushrooms and the performance of subsequent chemical reactions to achieve aminated derivatives. Furthermore, the growth of mushrooms can be avoided thus limiting the dependence on climate and weather, and potential legal and social challenges associated with the cultivation of mushrooms containing psychoactive compounds. The method can efficiently yield substantial quantities of aminated psilocybin derivatives.

     Turning now to methods of making the aminated psilocybin derivatives of the present disclosure, it is initially noted that the aminated psilocybin derivatives of the present disclosure may be prepared in any suitable manner, including by any organic chemical synthesis methods, biosynthetic methods, or a combination thereof. 
     One suitable method of making the aminated psilocybin derivatives of the present disclosure initially involves selecting and obtaining or preparing a reactant psilocybin derivative compound, and reacting the compound under suitable conditions to form an aminated psilocybin derivative. 
     Suitable reactant psilocybin derivative compounds include compounds comprising an indole prototype structure (see:  FIG.  2   ), including, for example, a chemical compound having formula (II): 
     
       
         
         
             
             
         
       
     
     wherein at least one of R 2 , R 4 , R 5 , R 6 , or R 7  is a reactive group selected from a nitro group, an azido group, or a hydrogen atom, and wherein R 2 , R 4 , R 5 , R 6 , or R 7  which are not a reactive group, are a hydrogen atom, an alkyl of O-alkyl group, and wherein R 3A  and R 3B  are each independently a hydrogen atom, an alkyl group, and acyl group, or an aryl group. Reactant psilocybin derivative compound (II) comprises a plurality of compounds, some examples of which will next be described. 
     In one example embodiment, the reactant psilocybin derivative can be selected to be a chemical compound wherein R 4  is an O-alkyl group, R 2 , R 5 , R 6 , and R 7  are a hydrogen atom, and R 3A  and R 3B  are each independently a hydrogen atom, an alkyl group, an acyl group, or an aryl group, such as, for example, the reactant psilocybin derivative shown in  FIGS.  8 A and  8 B . 
     In one example embodiment, the reactant psilocybin derivative can be selected to be a chemical compound wherein R 4  is an O-acyl group, R 2 , R 5 , R 6 , and R 7  are a hydrogen atom, and R 3A  and R 3B  are each independently a hydrogen atom, an alkyl group, an acyl group, or an aryl group, such as, for example, the reactant psilocybin derivative shown in  FIGS.  8 C and  8 D . 
     In one example embodiment, the reactant psilocybin derivative can be selected to be a chemical compound wherein R 4  is a hydroxyl group, R 2 , R 5 , R 6 , and R 7  are a hydrogen atom, and R 3A  and R 3B  are each independently a hydrogen atom, an alkyl group, an acyl group, or an aryl group, such as, for example, the reactant psilocybin derivative shown in  FIG.  8 E . 
     In one example embodiment, the reactant psilocybin derivative can be selected to be a chemical compound wherein R 4  is a phosphate group, R 2 , R 5 , R 6 , and R 7  are a hydrogen atom, and R 3A  and R 3B  are each independently a hydrogen atom, an alkyl group, an acyl group, or an aryl group, such as, for example, the reactant psilocybin derivative shown in  FIG.  8 F . 
     In one example embodiment, the reactant psilocybin derivative can be selected to be a chemical compound wherein R 4  is a hydrogen atom, R 2 , R 5 , R 6 , and R 7  are a hydrogen atom, and R 3A  and R 3B  are each independently a hydrogen atom, an alkyl group, an acyl group, or an aryl group, such as, for example, the reactant psilocybin derivative shown in  FIG.  8 G . 
     The reactant psilocybin derivative compounds may be provided in a more or less chemically pure form, for example, in the form of a psilocybin derivative preparation having a purity of at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or at least 99.9%. The psilocybin derivative may be chemically synthesized, or obtained from a fine chemical manufacturer. 
     In one example embodiment, the reactant psilocybin derivative compound, may be reacted with a nitrogenous compound with a nitrogenous compound, including, for example, a nitrogenous compound selected from nitric acid (HNO 3 ), a nitrate salt, an acyl nitrate, trifluoromethansulfonyl nitrate, nitrosonium tetrafluoroborate (NO 2 BF 4 ), and trifluoracetyl nitrate to initially form a nitrated psilocybin compound which can then be reacted under reducing conditions to form an aminated psilocybin compound. 
     Alternatively, in order to form the aminated psilocybin derivatives of the present disclosure a nitrated or azido group containing compound reactant psilocybin compounds may be obtained and reacted under reducing conditions to form the aminated psilocybin derivatives of the present disclosure. 
     Referring now to  FIGS.  9 A- 9 B , shown therein is an example reaction wherein 5-nitro-4-O-methyl-psilocybin derivative is converted to the 5-amino-4-O-methyl-psilocybin and some example N-substituted derivatives. 
     Referring now to  FIG.  9 A , shown therein is an example chemical reaction wherein nitrosonium tetrafluoroborate (NO 2 BF 4 ) is reacted with a 4-O-methyl-psilocybin derivative ( FIG.  8 A ) in a chemical reaction which results initially in the formation of an intermediate psilocybin derivative, notably a 4-O-methyl-5-nitro-psilocybin derivative. Subsequently, in the presence of hydrogen, the nitro group of the intermediate psilocybin derivative is reduced to an amino group under the catalytic hydrogenolysis condition with the help of palladium on charcoal. This affords the 5-amino-4-O-methyl-psilocybin derivative. 
     Subsequent N-substitutions on the formed amino group ( FIG.  9 B ) can be carried out using (1) N-acylations, such as N-acetylation with acetic anhydride or N-sulfonylation with sulfur trioxide-pyridine complex, (2) selective N-alkylation via a reaction with an aldehyde followed by a reduction of the intermediate imine, such as the reaction with acetaldehyde to form an intermediate imine, followed by a reduction with sodium borohydride. 
     Referring now to  FIG.  9 D , shown therein is an example of multistep synthesis of two 4-O-methyl-psilocybin derivative respectively aminated at C 5  (compound 9D-8, corresponding with the compound having chemical formula (IX), set forth herein) and C 7  (compound 9D-10, corresponding with the compound having chemical formula (XII), set forth herein) using 4-methoxyindole (compound 9D-1) as a starting compound. Thus, starting from 9D-1, a regioselective 2-nitrovinylation can be carried out using 1-(dimethylamino)-2-nitroethylene as an electrophile in the presence of trifluoroacetic acid as a catalyst. The reaction can provide the desired (E)-3-(2-nitroethenyl)-4-methoxyindole (9D-2) which can be directly reduced using sodium borohydride in a mixture of ethanol and THF, to provide the desired 3-(2-nitroethyl)-4-methoxyindole (9D-3), for example, yielding 33% (2 steps). The nitro group of the side chain can be further reduced using lithium aluminum hydride in THE to afford the intermediate 4-O-methy-tryptamine (9D-4), for example, yielding 57%. To facilitate subsequent nitration, compound 9D-4 can be protected with an excess of di-tert-butyl decarbonate in the presence of 4-N,N-dimethylaminopyridine to provide the tri-Boc-protected 4-O-methy-tryptamine (9D-5), for example, yielding 51%. Compound 9D-5 can then be subjected to a reaction with benzoyl nitrate, generated by mixing benzoyl chloride and silver nitrate in anhydrous acetonitrile. This can provide three nitrated products respectively at C 2  (compound 9D-6a, e.g., 7% yield), C 5  (compound 9D-6b, 14% yield), and C 7  (compound 9D-6c, 12%). Compound 9D-6b can subsequently be subjected to a reduction using ammonium formate in the presence of 10% palladium on charcoal in methanol at room temperature to afford the 5-aminated intermediate 9D-7 (e.g., 88% yield) which can be fully deprotected subsequently by a treatment with trifluoroacetic acid to furnish the desired 5-amino-4-O-methyl-psilocybin derivative (9D-8, e.g., 56% yield, corresponding with the compound having chemical formula (IX), set forth herein). Analogously, compound 9D-6c can also subjected to a reduction using ammonium formate in the presence of 10% palladium on charcoal in methanol at room temperature to afford the 7-aminated intermediate 9D-9 (e.g., 67% yield) which can further be fully deprotected by a treatment with trifluoroacetic acid to furnish the desired 7-amino-4-O-methyl-psilocybin derivative 9D-10, (e.g., 70% yield, corresponding with the compound having chemical formula (XII), set forth herein). 
     Thus, referring to the reactant psilocybin derivative compound having formula (II), the conditions can comprise: (i) appropriately protecting the side-chain amino group with one or two protecting groups (R 3a , R 3b ) along with or without the protection of N 1  using R 1 . It is noted that the protecting groups R 1 , R 3a , R 3b  can be, for example, an alkyl or an acyl group, such as an acetyl group or substituted acetyl group, such as trifluoroacetyl, or other groups, such as a carbamate group, e.g., fluorenylmethyloxycarbonyl (Fmoc), benzyloxycarbonyl, or tert-butyloxycarbonyl (Boc) which can, for example, be prepared by reacting with di-tert-butyl dicarbonate in the presence of 4-N,N-dimethylaminopyridine (DMAP). It is noted that the protection of N 1  with R 1  is optional depending on the nature of electrophile which is used in the nitration reaction (referring to  FIG.  9 D , see: e.g., reaction 9D-5 to 9D-6a, 9D-6b, 9D-6c), as well as the specific reaction conditions, e.g., pH, temperatures, solvents, catalysts; (ii) reacting the protected reactant psilocybin compound with a nitrogenous compound selected from nitric acid (HNO 3 ); a nitrate salt, such as AgNO 3 ; an acyl nitrate such as trifluoromethansulfonyl nitrate; benzoyl nitrate, nitrosonium tetrafluoroborate (NO 2 BF 4 ), and trifluoracetyl nitrate to form a nitrated compound having chemical formula (XXXI): 
     
       
         
         
             
             
         
       
     
     wherein at least one of R 2 , R 4 , R 5 , R 6 , or R 7  is a nitro group, and wherein each non-nitrated R 2 , R 5 , R 6 , or R 7  is a hydrogen atom, an alkyl group or O-alkyl group, wherein R 4  when it is not nitrated is a hydrogen atom, an alkyl group, O-alkyl group, a hydroxy group, or a phosphate group, and wherein R 3A  and R 3B  are a protective group, and wherein R 1  is a protective group or a hydrogen atom, and then (iii) reacting the nitrated compound under a reducing condition to form an aminated compound having chemical formula (XXXII): 
     
       
         
         
             
             
         
       
     
     wherein at least one of R 2 , R 4 , R 5 , R 6 , or R 7  is an amino group, and wherein each non-aminated R 2 , R 5 , R 6 , or R 7  is a hydrogen atom, an alkyl group or O-alkyl group, wherein R 4  when it is not aminated is a hydrogen atom, an alkyl group, O-alkyl group, a hydroxy group, or a phosphate group, and wherein R 3A  and R 3B  are a protective group, and wherein R 1  is a protective group or a hydrogen atom, then (iv) optionally substituting the at least one amino group at R 2 , R 4 , R 5 , R 6 , or R 7  group to form a N-substituted derivative, and then (v) removing the protecting groups (R 1 , R 3a , R 3b ) at N 1  and the side chain amino functionality, to thereby form a compound having chemical formula (I), and then (vi) optionally substituting the amino group of the side chain to form at least one N-substituted group. 
     Furthermore, referring now to  FIG.  9 C , shown therein is an alternative method for making the psilocybin derivatives of the present disclosure, notably a direct amination method using hydrogen peroxide and ammonia with the help of Cu/SiO 2  as a catalyst (T. Yu, R. Yang, S. Xia, G. Li, and C. Hu  Catal. Sci. Technol.,  2014, 4, 3159-3167). The presence of a catalyst is required in view of the fact that the reaction at practical temperatures and pressures is thermodynamically unfavorable. Such catalysts may include a platinum-containing catalyst, which may be held at high temperature, or a reducible metal oxide, for example, oxides of Fe, Ni, Co, Sn, Sb, Bi or Cu, as further described in, for example, Canadian Patent 553,988, and U.S. Pat. Nos. 2,948,755; and 4,031,106. 
     Similarly, referring further to  FIG.  9 A , having obtained the nitrated compound, the reduction reaction is preferably conducted in the presence of a catalyst capable of providing electrons, for example, a Cu, Sn, Ni or Pt containing catalyst. The reduction reaction under acidic conditions may initially lead to the formation of an intermediate psilocybin derivative possessing a cationic NH 3   +  group, which may be reacted with for example sodium hydroxide to form an amino group or a N-substituted amino group. 
     Thus, it will be clear that in one embodiment, in an aspect, in the chemical compound having formula (II), at least one of R 2 , R 4 , R 5 , R 6 , or R 7  in the reactant psilocybin derivative compound can be a hydrogen atom, and the reaction conditions can comprise reacting the reactant psilocybin compound with ammonia and hydrogen peroxide in the presence of a catalyst, such as Cu/SiO 2 , to form the chemical compound having formula (I) and to then optionally substitute the at least one amino group in the chemical compound having formula (I) to form at least one N-substituted group. 
     Furthermore, referring to  FIG.  9 D , 1-3 protecting groups can be introduced to protect the selected substrate compound shown in  FIG.  8 A , and the protecting groups can be a group different from Boc, such as an alkyl and/or acyl group like trifluoroacetyl, trichloroacetyl, dichloroacetyl, chloroacetyl, benzyloxycarbonyl, fluorenylmethyloxycarbonyl (Fmoc) etc. It will now be clear that, in an aspect hereof, the protected reactant psilocybin derivatives disclosed herein may be reacted with a nitrogenous compound, such as, for example, nitric acid (HNO 3 ), a nitrate salt, an acyl nitrate such as trifluoromethansulfonyl nitrate, benzoyl nitrate and trifluoracetyl nitrate, and ammonia to form the aminated psilocybin derivatives of the present disclosure. Thus, in addition to reactant psilocybin derivative shown in  FIG.  8 A , the example reactant psilocybin derivatives shown in  FIGS.  8 B- 8 G  may also be reacted with a suitable reagent to form example aminated psilocybin derivatives of the present disclosure. The 4-O-methyl-psilocybin derivative depicted an  FIG.  8 A  may be reacted to form, for example, the 4-O-methyl-5-amino-psilocybin derivative depicted in  FIG.  5 A  (as already noted), the 4-O-methyl-7-amino-psilocybin derivative depicted in  FIG.  6 A , and the 4-O-methyl-5,7-di-amino-psilocybin depicted in  FIG.  7 A . 
     Similarly, the 4-O-ethyl-psilocybin derivative depicted an  FIG.  8 B  may be reacted in similar reaction sequence to form, for example, the 4-O-ethyl-5-amino-psilocybin derivative depicted in  FIG.  5 B , the 4-O-ethyl-7-amino-psilocybin derivative depicted in  FIG.  6 B , and the 4-O-ethyl-5,7-di-amino-psilocybin depicted in  FIG.  7 B . 
     Similarly, the 4-acetyl-psilocybin derivative depicted an  FIG.  8 C  may be reacted in similar reaction sequence to form, for example, the 4-O-acetyl-5-amino-psilocybin derivative depicted in  FIG.  5 C , the 4-O-acetyl-7-amino-psilocybin derivative depicted in  FIG.  6 C , and the 4-O-acetyl-5,7-di-amino-psilocybin depicted in  FIG.  7 C . 
     Similarly, the 4-propanoyl-psilocybin derivative depicted an  FIG.  8 D  may be reacted in similar reaction sequence to form, for example, the 4-O-propanoyl-5-amino-psilocybin derivative depicted in  FIG.  5 D , the 4-O-propanoyl-7-amino-psilocybin derivative depicted in  FIG.  6 D , and the 4-O-propanoyl-5,7-di-amino-psilocybin depicted in  FIG.  7 D . 
     Similarly, the 4-hydroxy-psilocybin derivative depicted an  FIG.  8 E  may be reacted in similar reaction sequence to form, for example, the 4-hydroxy-5-amino-psilocybin derivative depicted in  FIG.  5 E , the 4-hydroxy-7-amino-psilocybin derivative depicted in  FIG.  6 E , and the 4-hydroxy-5,7-di-amino-psilocybin depicted in  FIG.  7 E . 
     Similarly, the 4-phospho-psilocybin derivative depicted an  FIG.  8 F  may be reacted in similar reaction sequence to form, for example, the 4-phosphate-5-amino-psilocybin derivative depicted in  FIG.  5 F , the 4-phosphate-7-amino-psilocybin derivative depicted in  FIG.  6 F , and the 4-phosphate-5,7-di-amino-psilocybin depicted in  FIG.  7 F . 
     Similarly, the psilocybin derivative depicted an  FIG.  8 G  may be reacted to form, for example, the 5-amino-psilocybin derivative depicted in  FIG.  5 G , the 47-amino-psilocybin derivative depicted in  FIG.  6 G , and the 5,7-di-amino-psilocybin depicted in  FIG.  7 G  as well as other analogs. 
     It is noted that the performance of the reactions, in example different embodiments, may involve amination of different carbon atoms, i.e., the C 2 , C 5 , C 6  and/or C 7  atom. In general, reaction conditions may be selected so that different carbon atoms or combinations thereof are aminated. Thus, for example, using either a C 5 -nitrated or C 5 -azido-substituted psilocybin or derivative as a starting material, the nitro or the azido group can be reduced to afford the 5-amino-psilocybin or derivative. The methods can be used to prepare any other mono-, di- or multi-aminated psilocybin derivatives from their corresponding nitrated or azido-substituted substrates (see: Kadam, H. K; Tilve, S. G. RSC Adv. 2015, 5, 83391-83407). Typical reduction conditions can be selected from a range of conventional conditions, such as catalytic hydrogenolysis with the help of heavy metal such as palladium on charcoal, palladium hydroxide on charcoal, Raney Nickel, platinum oxide; palladium on charcoal with ammonium formate; reactive metal such as zinc, iron or copper in an acidic media or with an salt, such as zinc/ammonium chloride; organic phosphine such as triphenylphosphine or trimethylphosphine (H.-C, Wu, J.-Q. Yu, J. B. Spencer, Org. Lett., 2004, 6, 4675-4678); sulfur containing reducing agent such as sodium hydrosulfite, sodium sulfide, hydrogen sulfide; tin(I) chloride; organic silanes (R. J. Rahaim, R. E. Maleczka, Jr., Org. Lett., 2005, 7, 5087-5090). The amination on the psilocybin and derivatives can also be achieved from a precursor substrate containing either an acyl azide (—CON 3 ) or amide (—CONH 2 ) functionality at any of the C 2 , C 5 , C 6 , C 7  positions via respectively the Curtis rearrangement (Scriven, E. F. V.; Turnbull, K., Chemical Reviews. 1988, 88, 297-368) or Hoffmann rearrangement (Baumgarten, H.; Smith, H; Stakiis, A, J. Org. Chem 1975, 40 (24): 3554-3561). The obtained amines can be further substituted with N-alkylation or N-acylation or a combination of the two, and it can also be modified with a sulfur containing acylating agent such as sulfur trioxide-pyridine, sulfonyl chloride. Furthermore, the obtained amines can also be reacted with an aldehyde or ketone for form the corresponding imines that can be reduced subsequently. 
     The reactions may be conducted in any suitable reaction vessel (e.g., a tube, bottle). Suitable solvents that may be used are for example, water, alcohol (such as methanol, ethanol, tetrahydrofuran (THF), N,N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), or a combination of solvents. Suitable temperatures may range from, for example, e.g., from about 20° C. to about 100° C. Furthermore, reaction times may be varied. As will readily be appreciated by those of skill in the art, the reaction conditions may be optimized, for example by preparing several psilocybin derivative reactants preparations and azido and reacting these in different reaction vessels under different reaction conditions, for example, at different temperatures, using different solvents, using different catalysts etc., evaluating the obtained aminated psilocybin derivative reaction product, adjusting reaction conditions, and selecting a desired reaction condition.

     Implementation of the foregoing example embodiment initially involves providing aminated psilocybin precursor compounds and host cells having a psilocybin biosynthetic enzyme complement. Accordingly, next, example aminated psilocybin precursor compounds and example host cells that may be selected and used in accordance with the present disclosure will be described. Thereafter, example methodologies and techniques will be described to contact and use the aminated psilocybin precursor compounds and cells to produce example aminated psilocybin compounds. 
     A variety of aminated psilocybin precursor compounds may be selected, prepared, and used. In some embodiments, for example, the aminated psilocybin precursor compound is a compound comprising an aminated indole prototype structure. Examples of such compounds are an aminated indole, e.g., 2-amino-indole, 4-amino-indole, 5-amino-indole, 6-amino-indole, and 7-amino-indole; and aminated tryptophan derivatives, e.g., 2-amino-tryptophan, 4-amino-tryptophan, 5-amino-tryptophan, 6-amino-tryptophan, and 7-amino-tryptophan. 
     Further aminated psilocybin precursor compounds that may be used include aminated indoles, having the formula (XXIX): 
     
       
         
         
             
             
         
       
     
     wherein at least one of R 2 , R 4 , R 5 , R 6  and R 7  is an amino group or N-substituted amino group, wherein R 2 , R 4 , R 5 , R 6  and R 7  when they are not aminated are hydrogen atoms, an alkyl group or O-alkyl group, wherein R 4  when it is not aminated is a hydrogen atom, an alkyl group or O-alkyl group, a hydroxy group, or a phosphate group.

     Turning now to the host cells that can be used in accordance with the present disclosure, it is initially noted that a variety of host cells may be selected in accordance with the present disclosure, including microorganism host cells, plant host cells, and animal host cells. 
     In accordance herewith the host cell includes a psilocybin biosynthetic enzyme complement. Such cells can be obtained in at least two ways. First, in some embodiments, host cells may be selected in which a psilocybin biosynthetic enzyme complement is naturally present. Generally cells naturally producing psilocybin for example, cells of fungal species belonging to the genus psilocybe, are suitable in this respect. Second, in some embodiments, a host cell that not naturally produces psilocybin may be modulated to produce a psilocybin biosynthetic enzyme complement. Thus, for example, a nucleic acid sequence encoding a psilocybin biosynthetic enzyme complement may be introduced into a host cell, and upon cell growth the host cells can make the psilocybin biosynthetic enzyme complement. 
     Typically a nucleic acid sequence encoding one or more enzymes constituting a psilocybin biosynthetic enzyme complement further includes one or more additional nucleic acid sequences, for example, a nucleic acid sequences controlling expression of the one or more enzymes, and these one or more additional nucleic acid sequences together with the nucleic acid sequence encoding the one or more enzymes can be said to form a chimeric nucleic acid sequence. 
     A host cell which upon cultivation expresses the chimeric nucleic acid can be selected and used in accordance with the present disclosure. Suitable host cells in this respect include, for example, microbial cells, such as bacterial cells, yeast cells, for example, and algal cells or plant cells. A variety of techniques and methodologies to manipulate host cells to introduce nucleic acid sequences in cells and attain expression exists and are well known to the skilled artisan. These methods include, for example, cation based methods, for example, lithium ion or calcium ion based methods, electroporation, biolistics, and glass beads based methods. As will be known to those of skill in the art, depending on the host cell selected, the methodology to introduce nucleic acid material in the host cell may vary, and, furthermore, methodologies may be optimized for uptake of nucleic acid material by the host cell, for example, by comparing uptake of nucleic acid material using different conditions. Detailed guidance can be found, for example, in Sambrook et al., Molecular Cloning, a Laboratory Manual, Cold Spring Harbor Laboratory Press, 2012, Fourth Ed. It is noted that the chimeric nucleic acid is a non-naturally occurring chimeric nucleic acid sequence and can be said to be heterologous to the host cell. 
     In some embodiments, the one or more enzymes constituting a psilocybin enzyme complement can be selected from by a nucleic acid sequence selected from the nucleic acid sequences consisting of:
         (a) SEQ. ID NO: 4, SEQ. ID NO: 8, SEQ. ID NO: 11 and SEQ. ID NO: 13;   (b) a nucleic acid sequence that is substantially identical to any one of the nucleic acid sequences of (a);   I a nucleic acid sequence that is substantially identical to any one of the nucleic acid sequences of (a) but for the degeneration of the genetic code;   (d) a nucleic acid sequence that is complementary to any one of the nucleic acid sequences of (a);   (e) a nucleic acid sequence encoding a polypeptide having any one of the amino acid sequences set forth in SEQ. ID NO: 5, SEQ. ID NO: 9, SEQ. ID NO: 12 and SEQ. ID NO: 14;   (f) a nucleic acid sequence that encodes a functional variant of any one of the amino acid sequences set forth in SEQ. ID NO: 5, SEQ. ID NO: 9, SEQ. ID NO: 12 and SEQ. ID NO: 14; and   (g) a nucleic acid sequence that hybridizes under stringent conditions to any one of the nucleic acid sequences set forth in (a), (b), (c), (d), (e) or (f).       

     Thus any of the nucleic acid sequence set forth in (a), (b), (c), (d), (e), (f) or (g) may be selected and introduced into a host cell. In particular, however the nucleic acid sequence is selected in conjunction with the selected psilocybin precursor compound, as hereinafter further discussed in reference with  FIG.  10   . 
     One example host cell that conveniently may be used is  Escherichia coli . The preparation of the  E. coli  vectors may be accomplished using commonly known techniques such as restriction digestion, ligation, gel electrophoresis, DNA sequencing, the polymerase chain reaction (PCR) and other methodologies. A wide variety of cloning vectors is available to perform the necessary steps required to prepare a recombinant expression vector. Among the vectors with a replication system functional in  E. coli , are vectors such as pBR322, the pUC series of vectors, the M13 mp series of vectors, pBluescript etc. Suitable promoter sequences for use in  E. coli  include, for example, the T7 promoter, the T5 promoter, tryptophan (trp) promoter, lactose (lac) promoter, tryptophan/lactose (tac) promoter, lipoprotein (lpp) promoter, and A phage PL promoter. Typically, cloning vectors contain a marker, for example, an antibiotic resistance marker, such as ampicillin or kanamycin resistance marker, allowing selection of transformed cells. Nucleic acid sequences may be introduced in these vectors, and the vectors may be introduced in  E. coli  by preparing competent cells, electroporation or using other well known methodologies to a person of skill in the art.  E. coli  may be grown in an appropriate medium, such as Luria-Broth medium and harvested. Recombinant expression vectors may readily be recovered from cells upon harvesting and lysing of the cells. 
     Another example host cell that may be conveniently used is a yeast cell. Example yeast host cells that can be used are yeast cells belonging to the genus  Candida, Kluyveromyces, Saccharomyces, Schizosaccharomyces, Pichia , Hansenuia, and  Yarrowia . In specific example embodiments, the yeast cell can be a  Saccharomyces cerevisiae  cell, a  Yarrowia lipolytica  cell, or  Pichia pastoris  cell. 
     A number of vectors exist for the expression of recombinant proteins in yeast host cells. Examples of vectors that may be used in yeast host cells include, for example, Yip type vectors, YEp type vectors, YRp type vectors, YCp type vectors, pGPD-2, pAO815, pGAPZ, pGAPZα, pHIL-D2, pHIL-S1, pPIC3.5K, pPIC9K, pPICZ, pPICZα, pPIC3K, pHWO10, pPUZZLE and 2 μm plasmids. Such vectors are known to the art and are, for example, described in Cregg et al, Mol Biotechnol. (2000) 16(1): 23-52. Suitable promoter sequences for use in yeast host cells are also known and described, for example, in Mattanovich et al., Methods Mol Biol, 2012, 824:329-58, and in Romanos et al, 1992, Yeast 8: 423-488. Examples of suitable promoters for use in yeast host cells include promoters of glycolytic enzymes, like triosephosphate isomerase (TPI), phosphoglycerate kinase (PGK), glyceraidehyde-3-phosphate dehydrogenase (GAPDH or GAP) and variants thereof, lactase (LAC) and galactosidase (GAL),  P. pastoris  glucose-6-phosphate isomerase promoter (PPGI), the 3-phosphoglycerate kinase promoter (PPGK), the glycerol aldehyde phosphate dehydrogenase promoter (PGAP), translation elongation factor promoter (PTEF),  S. cerevisiae  enolase (ENO-1),  S. cerevisiae  galactokinase (GAL1),  S. cerevisiae  alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH1, ADH2/GAP),  S. cerevisiae  triose phosphate isomerase (TPI),  S. cerevisiae  metallothionein (CUP1), and  S. cerevisiae  3-phosphoglycerate kinase (PGK), and the maltase gene promoter (MAL). Marker genes suitable for use in yeast host cells are also known to the art. Thus, antibiotic resistance markers, such as ampicillin resistance markers, can be used in yeast, as well as marker genes providing genetic functions for essential nutrients, for example, leucine (LEU2), tryptophan (TRP1 and TRP2), uracil (URA3, URA5, URA6), histidine (HIS3), and the like. Methods for introducing vectors into yeast host cells can, for example, be found in S. Kawai et al., 2010, Bioeng. Bugs 1(6): 395-403. 
     Further, guidance with respect to the preparation of expression vectors and introduction thereof into host cells, including in  E. coli  cells, yeast cells, and other host cells, may be found in, for example: Sambrook et al., Molecular Cloning, a Laboratory Manual, Cold Spring Harbor Laboratory Press, 2012, Fourth Ed. 
     Thus, to briefly recap, a host cell comprising a chimeric nucleic acid comprising (i) a nucleic acid sequence controlling expression in a host cell and (ii) a nucleic acid sequence encoding a psilocybin biosynthetic enzyme complement, can be prepared in accordance with the present disclosure. 
     In accordance herewith, host cells are grown to multiply and to express a chimeric nucleic acid. Expression of the chimeric nucleic acid results in the biosynthetic production in the host cell of a psilocybin biosynthetic enzyme complement. Growth media and growth conditions can vary depending on the host cell that is selected, as will be readily appreciated to those of ordinary skill in the art. Growth media typically contain a carbon source, one or several nitrogen sources, essential salts including salts of potassium, sodium, magnesium, phosphate and sulphate, trace metals, water soluble vitamins, and process aids including but not limited to antifoam agents, protease inhibitors, stabilizers, ligands, and inducers. Example carbon sources are e.g., mono- or disaccharides. Example nitrogen sources are, e.g., ammonia, urea, amino acids, yeast extract, corn steep liquor and fully or partially hydrolyzed proteins. Example trace metals are e.g., Fe, Zn, Mn, Cu, Mo and H 3 BOs. Example water soluble vitamins are e.g. biotin, pantothenate, niacin, thiamine, p-aminobenzoic acid, choline, pyridoxine, folic acid, riboflavin, and ascorbic acid. Further, specific example media include liquid culture media for the growth of yeast cells and bacterial cells including, Luria-Bertani (LB) broth for bacterial cell cultivation, and yeast extract peptone dextrose (YEPD or YPD), for yeast cell cultivation. Further media and growth conditions can be found in Sambrook et al., Molecular Cloning, a Laboratory Manual, Cold Spring Harbor Laboratory Press, 2012, Fourth Ed. 
     In order for the host cells to produce the aminated psilocybin compound, the cells are provided with a precursor compound. Thus in accordance herewith, host cells may be contacted with a psilocybin precursor compound. In some embodiments, a psilocybin precursor compound can be exogenously supplied, for example, by including a psilocybin precursor compound in the growth medium of the host cells, and growing the host cells in a medium including the psilocybin precursor compound. 
     Referring next to  FIG.  10   , shown therein is an example biosynthetic pathway showing the conversion of example psilocybin precursor compounds to form an aminated psilocybin. Thus, as can be appreciated from  FIG.  10   , various psilocybin precursor compounds may be selected and prepared in aminated form, in conjunction with a psilocybin biosynthetic enzyme complement. Thus, by way of example, aminated tryptophan (e.g., 2-,5-, 6-, or 7-aminated tryptophan) may be selected and contacted with a host cell comprising a psilocybin biosynthetic enzyme complement comprising tryptophan decarboxylase and optionally N-acetyl transferase, and upon growth of the cells aminated psilocybin derivatives can be formed. By way of further example, aminated indole (e.g., 2-,5-, 6-, or 7-aminated indole) may be selected and contacted with a host cell comprising a psilocybin biosynthetic enzyme complement comprising tryptophan synthase subunit B polypeptide and tryptophan decarboxylase and optionally N-acetyl transferase, and upon growth of the cells aminated psilocybin derivatives can be formed 
     In some embodiments, the psilocybin precursor compound can be an aminated psilocybin precursor compound which is exogenously supplied to a host cell, for example by inclusion in the host cell&#39;s growth medium. Thus, for example, referring to  FIG.  10   , it will be understood that in accordance herewith, for example, 7-amino-indole or 7-amino-tryptophan, may be included in the growth medium of a host cell comprising a psilocybin biosynthetic enzyme complement.

Thus, in this manner, aminated psilocybin derivatives in more or less pure form may be prepared. 
     Similarly, other methods of making the aminated psilocybin compounds that may be used in accordance herewith may yield preparations of aminated compounds of at least about 60% (w/w), about 70% (w/w), about 80% (w/w), about 90% (w/w), about 95% (w/w), about 96% (w/w), about 97% (w/w), about 98% (w/w), or about 99% (w/w) purity. 
     It will now be clear form the foregoing that novel aminated psilocybin derivatives are disclosed herein. The aminated psilocybin compounds may be formulated for use as a pharmaceutical drug or recreational drug. The aminated psilocybin compounds may also be used as a feedstock to produce other psilocybin derivatives. 
     Hereinafter are provided examples of specific implementations for performing the methods of the present disclosure, as well as implementations representing the compositions of the present disclosure. The examples are provided for illustrative purposes only, and are not intended to limit the scope of the present disclosure in any way.

     EXAMPLES 
     Example 1—Chemical Synthesis of a First, a Second and a Third Aminated Psilocybin Derivative 
     Referring to  FIG.  9 D , shown therein is a 7-step synthesis for two 4-O-methyl-psilocybin derivatives respectively aminated at C 5  and C 7  from 4-methoxyindole. 
     The first step involved the regioselective 3-nitrovinylation of 4-methoxyindole (9D-1). Under argon, 4-methoxy indole (9D-1) (4000 mg, 27.18 mmol, 1.00 eq) and 1-(dimethylamino)-2-nitroethylene (3472 mg, 29.90 mmol, 1.10 eq) were dissolved in trifluoroacetic acid (20.8 mL, 272 mmol, 10.0 eq) and allowed to stir at room temperature for 3 hours until complete as determined by TLC (1:1 ethyl acetate-hexanes). The dark red solution was diluted with ethyl acetate (100 mL) and carefully poured over saturated sodium bicarbonate solution (200 mL). This biphasic mixture was then separated, and the aqueous phase extracted with ethyl acetate (4×100 mL). The combined organic extracts were washed with brine, dried with MgSO 4 , and concentrated under reduced pressure to yield the crude product 9D-2 (5600 mg) that was used directly without any further purification. 
     The second step involved the conjugated reduction of the alkene functionality of compound 9D-2. To a solution of crude compound 9D-2 (5600 mg) in ethanol (50 mL) and THE (50 mL) under ambient air was added sodium borohydride (5141 mg, 136 mmol) in small portions, waiting for effervescence to decrease between additions. This mixture was allowed to stir at room temperature for 18 hours at which point reaction was complete as determined by TLC (1:1 ethyl acetate-hexanes). The reaction was quenched by pouring over ice-water (200 ml) and extracted with DCM (4×100 mL). The combined organic extracts were dried with MgSO 4  and concentrated under reduced pressure to yield the crude product as a brown solid. Purification by column chromatography on silica gel using a 10% to 50% ethyl acetate-hexanes gradient to yield compound 9D-3 as a white solid (1950 mg, 8.94 mg, 33% over 2 steps).  1 H NMR (400 MHz, CDCl 3 ): δ (ppm)=8.02 (s, 1H), 7.15 (t, J=8.0 Hz, 1H), 7.00 (dd, J=8.3, 0.7 Hz, 1H), 6.94 (dd, J=2.5, 1.0 Hz, 1H), 6.55 (dd, J=7.8, 0.7 Hz, 1H), 4.76 (t, J=7.2 Hz, 2H), 3.97 (s, 3H), 3.57 (td, J=7.2, 0.8 Hz, 2H). 
     The third step involved the reduction of the nitro functionality of compound 3. Under argon in a flame-dried flask compound 9D-3 (800 mg, 3.63 mmol, 1.00 eq) was dissolved in anhydrous THE (20 mL) and cooled to 0° C. To this solution was added 1 M lithium aluminum hydride in THE (18.2 mL, 18.2 mmol, 5.00 eq), causing a colour change to yellow. The reaction mixture was heated to reflux for 2.5 hours, yielding a milky-white solution. After cooling to 0° C., the reaction was quenched with 10% water-THE (15 mL) and allowed to stir for 10 minutes. The precipitated white solids were filtered off and the filter-cake rinsed with THE (10 mL), dichloromethane (10 mL) and methanol (10 mL). The organic filtrate was dried with MgSO 4  and concentrated under reduced pressure to yield compound 9D-4 as an off-white solid (395 mg, 2.08 mmol, 57%).  1 H NMR (400 MHz, CDCl 3 ): δ (ppm)=8.12 (s, 1H), 7.09 (t, J=7.9 Hz, 1H), 6.97 (d, J=8.1 Hz, 1H), 6.89 (d, J=2.2 Hz, 1H), 6.50 (d, J=7.8 Hz, 1H), 3.92 (s, 3H), 3.02 (s, 4H). 
     The fourth step involved the full protection of the side-chain amino group and the N1 of compound 9D-4. Under argon in a flame-dried flask, compound 9D-4 (245 mg, 1.29 mmol, 1.00 eq) was dissolved in anhydrous acetonitrile (10 mL). To this solution, di-tert-butyl dicarbonate (2811 mg, 12.9 mmol, 10.0 eq) and 4-dimethylaminopyridine (157 mg, 1.29 mmol, 1.00 eq) was added, and the reaction mixture allowed to stir at room temperature for 20 hours. Water (20 mL) was added, and the mixture was extracted with dichloromethane (4×30 mL). The combined organic extracts were washed with brine (25 mL), dried with MgSO 4 , and concentrated under vacuum to yield the crude product as a dark red oil. Purification by column chromatography on silica gel using an 8% to 15% ethyl acetate-hexanes gradient yielded compound 9D-5 as an oily white solid (325 mg, 0.663 mmol, 51%).  1 H NMR (400 MHz, CDCl 3 ): δ (ppm)=7.74 (d, J=8.4 Hz, 1H), 7.23-7.13 (m, 2H), 6.63 (d, J=7.9 Hz, 1H), 3.91 (m, 5H), 3.08 (ddd, J=7.5, 6.3, 1.0 Hz, 2H), 1.63 (s, 9H), 1.38 (s, 18H). 
     The fifth step involved the regioselective nitration of compound 9D-5. A flame-dried round-bottom flask was charged with compound 9D-5 (325 mg, 0.662 mmol, 1.00 eq), silver nitrate (124 mg, 0.729 mmol, 1.10 eq), and dry acetonitrile (2.5 mL), then cooled to 0° C. under argon atmosphere. Benzoyl chloride (102 mg, 0.729 mmol, 1.10 eq) was diluted with dry acetonitrile (0.5 mL) and added dropwise to the reaction mixture, which was then allowed to stir at 0° C. for 3 hours. The reaction mixture was diluted with ethyl acetate (10 mL) and the precipitated salts were removed via vacuum filtration and washed with ethyl acetate (5 mL). The organic filtrate was washed with water (3×20 mL) and saturated Na 2 CO 3  (20 mL), then dried with MgSO 4  and solvent removed in vacuo. The crude mixture was purified by column chromatography on silica gel using a gradient of 5 to 15% ethyl acetate-hexanes to afford compounds 9D-6a (25 mg, 0.047 mmol, 7%), 9D-6b (48 mg, 0.090 mmol, 14%), and 9D-6c (45 mg, 0.078 mmol, 12%) in order of elution as yellow solids. Compound 9D-6a:  1 H NMR (400 MHz, CDCl 3 ): δ (ppm)=7.62 (dd, J=8.5, 0.7 Hz, 1H), 7.41 (t, J=8.3 Hz, 1H), 7.41 (s, 1H), 6.70 (dd, J=8.1, 0.7 Hz, 1H), 4.07-4.02 (m, 2H), 3.94 (s, 3H), 3.37-3.31 (m, 2H), 1.55 (s, 9H), 1.33 (s, 18H). Compound 9D-9D-6b:  1 H NMR (400 MHz, CDCl 3 ): δ (ppm)=8.00-7.94 (m, 1H), 7.87 (d, J=9.0 Hz, 1H), 7.38 (s, 1H), 4.01 (s, 3H), 3.94 (t, J=7.6 Hz, 2H), 3.10 (t, J=7.6 Hz, 2H), 1.65 (s, 9H), 1.41 (s, 18H). Compound 9D-6c:  1 H NMR (400 MHz, CDCl 3 ): δ (ppm)=7.82 (d, J=8.8 Hz, 1H), 6.64 (d, J=8.8 Hz, 1H), 4.02 (s, 3H), 3.91 (dd, J=7.4, 6.4 Hz, 2H), 3.08 (td, J=6.8, 6.4, 1.0 Hz, 2H), 1.57 (s, 9H), 1.40 (s, 18H). 
     The sixth step involved the reduction of the nitro group. To a vigorously stirring solution of compound 9D-6b (27 mg, 0.050 mmol, 1.0 eq) in methanol (2 mL) was added 10% palladium on activated charcoal (23 mg, 0.021 mmol, 0.50 eq) followed by ammonium formate (46 mg, 0.70 mmol, 17 eq). The reaction mixture was allowed to stir at room temperature for 2 hours until complete as determined by TLC (1:4 ethyl acetate-hexanes). The catalyst was removed and methanol was removed under vacuum. The residue was taken up in dichloromethane (10 mL), washed with brine (10 mL), the organic phase dried with MgSO 4  and concentrated under reduced pressure to yield compound 9D-7 as a colourless film (22 mg, 0.044 mmol, 88%).  1 H NMR (400 MHz, CDCl 3 ): δ (ppm)=7.72 (s, 1H), 7.26-7.18 (m, 1H), 6.76 (d, J=8.7 Hz, 1H), 3.96-3.91 (m, 2H), 3.84 (s, 3H), 3.09-3.00 (m, 2H), 1.62 (s, 9H), 1.43 (s, 18H). 
     Similarly, the nitro group of compound 9D-6c can also be reduced in an analogous manner. To a vigorously stirring solution of compound 9D-6c (22 mg, 0.041 mmol, 1.0 eq) in methanol (2 mL) was added 10% palladium on activated charcoal (22 mg, 0.021 mmol, 0.50 eq) followed by ammonium formate (44 mg, 0.70 mmol, 17 eq). The reaction mixture was allowed to stir at room temperature for 2 hours and monitored by TLC (1:4 ethyl acetate-hexanes). The catalyst was removed and methanol was removed under vacuum. The residue was taken up in dichloromethane (10 mL), washed with brine (10 mL), the organic phase dried with MgSO 4  and concentrated under reduced pressure to yield compound 9D-9 as a brown film (14 mg, 0.028 mmol, 67%).  1 H NMR (600 MHz, CDCl 3 ): δ (ppm)=7.13 (s, 1H), 6.69 (d, J=8.3 Hz, 1H), 6.57 (dt, J=8.5, 1.0 Hz, 1H), 3.93-3.87 (m, 2H), 3.85 (s, 3H), 3.04 (t, J=6.9 Hz, 2H), 1.61 (s, 9H), 1.40 (s, 18H). 
     The seventh step involved the removal of all protecting group. To a solution of 9D-7 (22 mg, 0.044 mmol, 1.0 eq) in dichloromethane (1.0 mL) and methanol (0.1 mL) was added trifluoroacetic acid (0.15 mL, 1.5 mmol, 35 eq) dropwise. The reaction mixture was heated to 40° C. for 2 hours, then allowed to stir at room temperature for 18 hours. As the reaction was incomplete, the reaction was heated for a further 20 hours at 40° C. The reaction mixture was concentrated under reduced pressure to yield compound 9D-8 (5 mg, 0.2 mmol, 56%).  1 H NMR (600 MHz, D 2 O): δ (ppm)=7.24 (d, J=8.5 Hz, 1H), 7.22 (s, 1H), 7.03 (d, J=8.5 Hz, 1H), 3.81 (s, 3H), 3.23 (t, J=7.0 Hz, 2H), 3.10 (t, J=7.0 Hz, 2H). 
     It is noted that compound 9D-8 corresponds with an example compound having chemical formula (IX):

     Similarly, compound 9D-9 can also be deprotected in an analogous manner. To a solution of 9D-9 (14 mg, 0.028 mmol, 1.0 eq) in dichloromethane (1.0 mL) and methanol (0.1 mL) was added trifluoroacetic acid (0.064 mL, 0.83 mmol, 30 eq). The reaction mixture was heated to 40° C. for 20 hours. The reaction mixture was concentrated under reduced pressure to yield compound 9D-10 (4 mg, 0.2 mmol, 70%).  1 H NMR (600 MHz, D 2 O): δ (ppm)=7.25 (s, 1H), 7.18 (d, J=8.3 Hz, 1H), 6.66 (d, J=8.3 Hz, 1H), 3.96 (s, 3H), 3.30 (t, J=6.8 Hz, 2H), 3.21 (t, J=6.9 Hz, 2H). 
     It is noted that compound 9D-10 corresponds with an example compound having chemical formula (XII):

     Assessment of Cell Viability Upon Treatment of Aminated Psilocybin Derivatives 
     To establish suitable ligand concentrations for competitive binding assays, PrestoBlue assays were first performed. The PrestoBlue assay measures cell metabolic activity based on tetrazolium salt formation, and is a preferred method for routine cell viability assays (Terrasso et al., 2017, J Pharmacol Toxicol Methods 83: 72). Results of these assays were conducted using both control ligands (e.g., psilocybin, psilocin, DMT) and novel derivatives, in part as a pre-screen for any remarkable toxic effects on cell cultures up to concentrations of 1 mM. A known cellular toxin (Triton X-100, Pyrgiotakis G. et al., 2009, Ann. Biomed. Eng. 37: 1464-1473) was included as a general marker of toxicity. Drug-induced changes in cell health within simple in vitro systems such as the HepG2 cell line are commonly adopted as first-line screening approaches in the pharmaceutical industry (Weaver et al, 2017, Expert Opin Drug Metab Toxicol 13: 767). HepG2 is a human hepatoma that is most commonly used in drug metabolism and hepatotoxicity studies (Donato et al., 2015, Methods Mol Biol 1250: 77). Herein, HepG2 cells were cultured using standard procedures using the manufacture&#39;s protocols (ATCC, HB-8065). Briefly, cells were cultured in Eagle&#39;s minimum essential medium supplemented with 10% fetal bovine serum and grown at 37° C. in the presence of 5% CO 2 . To test the various compounds with the cell line, cells were seeded in a clear 96-well culture plate at 20,000 cells per well. After allowing cells to attach and grow for 24 hours, compounds were added at 1 μM, 10 μM, 100 μM, and 1 mM. Methanol was used as vehicle, at concentrations 0.001, 0.01, 0.1, and 1%. As a positive control for toxicity, TritonX concentrations used were 0.0001, 0.001, 0.01 and 0.1%. Cells were incubated with compounds for 48 hours before accessing cell viability with the PrestoBlue assay following the manufacture&#39;s protocol (ThermoFisher Scientific, P50200). PrestoBlue reagent was added to cells and allowed to incubate for 1 hour before reading. Absorbance readings were performed at 570 nm with the reference at 600 nm on a SpectraMax iD3 plate reader. Non-treated cells were assigned 100% viability. Bar graphs show the mean +/−SD, n=3. Significance was determined by 2-way ANOVA followed by Dunnett&#39;s multiple comparison test and is indicated by *** (P&lt;0.0001), **(P&lt;0.001), *(P&lt;0.005). Data acquired for the derivative having chemical formula (IX) is displayed as “IX” on the x-axis of  FIG.  11 A .). Data acquired for the derivative having chemical formula (XII) is displayed as “XII” on the x-axis of  FIG.  11 B . 
     Radioligand Receptor Binding Assays. 
     Evaluation of drug binding is an essential step to characterization of all drug-target interactions (Fang 2012, Exp Opin Drug Discov 7:969). The binding affinity of a drug to a target is traditionally viewed as an acceptable surrogate of its in vivo efficacy (NGAez et al., 2012, Drug Disc Today 17: 10). Competition assays, also called displacement or modulation binding assays, are a common approach to measure activity of a ligand at a target receptor (Flanagan 2016, Methods Cell Biol 132: 191). In these assays, standard radioligands acting either as agonists or antagonists are ascribed to specific receptors. In the case of G protein-coupled receptor 5-HT 2A , [ 3 H]ketanserin is a well-established antagonist used routinely in competition assays to evaluate competitive activity of novel drug candidates at the 5-HT 2A  receptor (Maguire et al., 2012, Methods Mol Biol 897: 31). Thus, to evaluate activity of novel psilocybin derivatives at the 5-HT 2A  receptor, competition assays using [ 3 H]ketanserin were employed as follows. SPA beads (RPNQ0010), [ 3 H] ketanserin (NET1233025UC), membranes containing 5-HT 2A  (ES-313-M400UA), and isoplate-96 microplate (6005040) were all purchased from PerkinElmer. Radioactive binding assays were carried out using Scintillation Proximity Assay (SPA). For saturation binding assays, mixtures of 10 ug of membrane containing 5-HT 2A  receptor was pre-coupled to 1 mg of SPA beads at room temperature in a tube rotator for 1 hour in binding buffer (50 mM Tris-HCl pH7.4, 4 mM CaCl 2 , 1 mM ascorbic acid, 10 μM pargyline HCl). After pre-coupling, the beads and membrane were aliquoted in an isoplate-96 microplate with increasing amounts of [ 3 H]ketanserin (0.1525 nM to 5 nM) and incubated for two hours at room temperature in the dark with shaking. After incubation, the samples were read on a MicroBeta 2 Microplate Counter (Perkin Elmer). Determination of non-specific binding was carried out in the presence of 20 μM of spiperone (S7395-250MG, Sigma). Equilibrium binding constants for ketanserin (K d ) were determined from saturation binding curves using the ‘one-site saturation binding analysis’ method of GraphPad PRISM software (Version 9.2.0). Competition binding assays were performed using fixed (1 nM) [ 3 H]ketanserin and different concentrations of tryptophan (3 nM to 1 mM), psilocin (30 pM to 10 μM) or unlabeled test compound (3 nM to 1 mM) similar to the saturation binding assay. K i  values were calculated from the competition displacement data using the competitive binding analysis from GraphPad PRISM software. Tryptophan was included as a negative control as it has no activity at the 5-HT 2A  receptor. In contrast, psilocin was used as a positive control since it has established binding activity at the 5-HT 2A  receptor (Kim et al., 2020, Cell 182: 1574).  FIG.  11 D  depicts the saturation binding curves for [ 3 H]ketanserin at the 5-HT 2A  receptor. Panel 1 shows the specific saturation ligand binding of [ 3 H]ketanserin (from 0.1525 nM to 5 nM) to membranes containing 5-HT 2A  receptor, which was obtained after subtracting non-specific binding values (shown in Panel 2). Specific binding in counts per minute (cpm) was calculated by subtracting non-specific binding from total binding. Specific binding (pmol/mg) was calculated from pmol of [ 3 H]ketanserin bound per mg of protein in the assay. The K d  was calculated by fitting the data with the one-site binding model of PRISM software (version 9.2.0).  FIG.  11 E  (top panel) shows the competition binding curve for psilocin as a positive control (binding).  FIG.  11 E  (bottom panel) shows the competition binding curve for tryptophan as a negative control (no binding).  FIG.  11 F  shows competition binding curve for compound with formula (IX), designated “IX” in the figure.  FIG.  11 G  shows competition binding curve for compound with formula (XII), designated “XII” in the figure. 
     Cell Lines and Control Ligands Used to Assess Activity at 5-HT 1A . 
     CHO-K1/Gα 15  (GenScript, M00257) (−5-HT 1A ) and CHO-K1/5-HT 1A /Gα 15  (GenScript, M00330) (+5-HT 1A ) cells lines were used. Briefly, CHO-K1/Gα 15  is a control cell line that constitutively expresses Gα 15  which is a promiscuous G q  protein. This control cell line lacks any transgene encoding 5-HT 1A  receptors, but still responds to forskolin; thus, cAMP response to forskolin should be the same regardless of whether or not 5-HT 1A  agonists are present. Conversely, CHO-K1/5-HT 1A /Gα 15  cells stably express 5-HT 1A  receptor in the CHO-K1 host background. Notably, Gα 15  is a promiscuous G protein known to induce calcium flux response, present in both control and 5-HT 1A  cell lines. In +5-HT 1A  cells, Gα 15  may be recruited in place of G αi/o , which could theoretically dampen cAMP response (Rojas and Fiedler 2016, Front Cell Neurosci 10: 272). Thus, we included two known 5-HT 1A  agonists, DMT (Cameron and Olson 2018, ACS Chem Neurosci 9: 2344) and serotonin (Rojas and Fiedler 2016, Front Cell Neurosci 10: 272) as positive controls to ensure sufficient cAMP response was observed, thereby indicating measurable recruitment of G αi/o  protein to activated 5-HT 1A  receptors. In contrast, tryptophan is not known to activate, or modulate in any way, 5-HT 1A  receptors, and was thus used as a negative control. Cells were maintained in complete growth media as recommended by supplier (GenScript) which is constituted as follows: Ham&#39;s F12 Nutrient mix (HAM&#39;s F12, GIBCO #11765-047) with 10% fetal bovine serum (FBS) (Thermo Scientific #12483020), 200 μg/ml zeocin (Thermo Scientific #R25005) and/or 100 μg/ml hygromycin (Thermo Scientific #10687010). The cells were cultured in a humidified incubator with 37° C. and 5% CO 2 . Cells maintenance was carried out as recommended by the cell supplier. Briefly, vials with cells were removed from the liquid nitrogen and thawed quickly in 37° C. water bath. Just before the cells were completely thawed the vial&#39;s outside was decontaminated by 70% ethanol spray. The cell suspension was then retrieved from the vial and added to warm (37° C.) complete growth media, and centrifuged at 1,000 rpm for 5 minutes. The supernatant was discarded, and the cell pellet was then resuspended in another 10 ml of complete growth media, and added to the 10 cm cell culture dish (Greiner Bio-One #664160). The media was changed every third day until the cells were about 90% confluent. The ˜90% confluent cells were then split 10:1 for maintenance or used for experiment. 
     Evaluation of 5-HT 1A  Receptor Modulation 
     As 5-HT 1A  activation inhibits cAMP formation, the ability of test molecules to modulate 5-HT 1A  response was measured via changes in the levels of cAMP produced due to application of 4 μM forskolin. The change in intracellular cAMP levels due to the treatment of novel molecules was measured using cAMP-Glo Assay kit (Promega #V1501). Briefly, +5-HT 1A  cells were seeded on 1-6 columns and base −5-HT 1A  cells were seeded on columns 7-12 of the white walled clear bottom 96-well plate (Corning, #3903). Both cells were seeded at the density of 30,000 cells/well in 100 μl complete growth media and cultured 24 hrs in humidified incubator at 37° C. and 5% CO 2 . On the experiment day, the media of cells was replaced with serum/antibiotic free culture media. Then the cells were treated for 20 minutes with test molecules dissolved in induction medium (serum/antibiotic free culture media containing 4 μM forskolin, 500 μM IBMX (isobutyl-1-methylxanthine, Sigma-Aldrich, Cat. #17018) and 100 μM (RO 20-1724, Sigma-Aldrich, Cat. #B8279)). Forskolin induced cAMP formation whereas IBMX and RO 20-1724 inhibited the degradation of cAMP. PKA was added to the lysate, mixed, and subsequently the substrate of the PKA was added. PKA was activated by cAMP, and the amount of ATP consumed due to PKA phosphorylation directly corresponded to cAMP levels in the lysate. Reduced ATP caused reduced conversion of luciferin to oxyluciferin, conferring diminished luminescence as the result of 5-HT 1A  activation. Conversely, enhanced luminescence was expected in cases where 5-HT 1A  receptor modulation—imparted by a test molecule—caused downstream increases in ATP, thus imparting enhanced conversion of luciferin to oxyluciferin.  FIG.  11 I  shows increased luminescence resulting from decreased dosages of forskolin (and decreased cAMP) in +5HT 1A  cell culture.  FIG.  11 J  illustrates reduced luminescence (i.e., increased cAMP) in the presence of fixed (4 μM) forskolin as dosages of DMT decrease, revealing 5-HT 1A  activity of DMT.  FIG.  11 K  illustrates no trend in luminescence (i.e., no trend in cAMP levels) in the presence of fixed (4 μM) forskolin, as dosages of tryptophan decrease, revealing a lack of 5-HT 1A  modulation for tryptophan.  FIG.  11 L  illustrates increased % cAMP levels in the presence of fixed (4 μM) forskolin as dosages of serotonin decrease, revealing 5-HT 1A  binding activity of serotonin in +5HT 1A  cell cultures. Conversely, this trend of increasing % cAMP levels with decreasing serotonin is not observed in −5HT 1A  cell cultures. 
       FIG.  11 M  illustrates increased % cAMP levels in the presence of fixed (4 μM) forskolin as dosages of compound (IX) decrease, revealing 5-HT 1A  binding activity of compound (IX) in +5HT 1A  cell cultures. Conversely, this trend of increasing % cAMP levels with decreasing compound (IX) is not observed in −5HT 1A  cell cultures. Note that compound (IX) is shown simply as (IX) along the x-axis. For  FIGS.  11 I- 11 M , error bars represent results of three experiments (n=3). 
     Example 2—Biochemical Synthesis of a Fourth Aminated Psilocybin Derivative 
       E. coli  strain Ec-1 was constructed as follows. For plasmid cloning, Top10 or XL1-blue strains were used depending on antibiotic markers. Standard LB media was used for culturing. For gene expression and feeding experiments, the parent host strain employed was BL21 (DE3). The plasmid pETM6-H10-TmTrpB-2F3-V5-BaTDC-FLAG was created by first cloning the in-frame, C-terminally V5-tagged (SEQ. ID NO: 6, SEQ. ID NO: 7) TmTrpB-2F3 (SEQ. ID NO: 8, SEQ. ID NO: 9) into the NdeI/XhoI site of pETM6-H10 (SEQ. ID NO: 10) to create pETM6-H 10 -TmTrpB-2F3-V5. This intermediate plasmid was digested with SpeI and SalI, and in-frame, C-terminally FLAG tagged (SEQ. ID NO: 2, SEQ. ID NO: 3) BaTDC (SEQ. ID NO: 11, SEQ. ID NO: 12) was cloned into the site with XbaI and SalI, nullifying the SpeI restriction site. In this setup, the T7 polymerase was able to drive the expression of the polycistronic DNA containing both TmTrpB-2F3 and BaTDC. The target plasmid pETM6-H 10 -TmTrpB-2F3-V5-BaTDC-FLAG was transformed into BL21 (DE3) cells, and ampicillin was used to select for the correct clones containing the plasmid. Scaled-up culturing of engineered  E. coli  was conducted as follows: seed cultures were inoculated in AMM (Jones et al. 2015, Sci Rep. 5: 11301) medium overnight. The overnight culture was then divided into two flasks containing 500 mL each of AMM medium additionally containing 0.5% (w/v) serine, 1M IPTG, 50 ug/L ampicillin, and 100 mg/L aminated indole feedstock (5,7-dimethyl-1H-indol-4-ylamine; 1clickchemistry, www.1 clickchemistry.com) for conversion by Ec-1. Cultures were grown for 24 h. Cultures were then centrifuged (10,000 g×5 minutes) to remove cellular content, and culture broth containing secreted derivative was stored at −80° C. until further processing. 
     Analysis and Purification, 
     Analysis was carried out using high-resolution LC-HESI-LTQ-Orbitrap-XL MS (Thermo Fisher Scientific), employing a modified version of a method described previously (Chang et al., 2015, Plant Physiol. 169: 1127-1140), with the exception that liquid chromatography was carried out using an UltiMate 3000 HPLC (Thermo Fisher Scientific) equipped with a Poroshell 120 SB-C18 column (Agilent Technologies) instead of an Accela HPLC system (Thermo Fisher Scientific) equipped with a Zorbax C18 column (Agilent Technologies). Briefly, 100 microliters of culture media were were dried and resuspended in 100 microliters of DMSO. One tenth (10 microliters) of this suspension was injected at a flow rate of 0.5 mL/min and a gradient of solvent A (water with 0.1% of formic acid) and solvent B (ACN with 0.1% formic acid) as follows: 100% to 0% (v/v) solvent A over 5 min; isocratic at 0% (v/v) for 1 min; 0% to 100% (v/v) over 0.1 min; and isocratic at 100% (v/v) for 1.9 min. Total run time was 8 minutes. Heated ESI source and interface conditions were operated in positive ion mode as follows: vaporizer temperature, 400° C.; source voltage, 3 kV; sheath gas, 60 au, auxiliary gas, 20 au; capillary temperature, 380° C.; capillary voltage, 6 V; tube lens, 45 V. Instrumentation was performed as a single, HR scan event using Orbitrap detection of m/z in the range of 100-500 m/z. Ion injection time was 300 ms with scan time of 1 s. External and internal calibration procedures ensured &lt;2 ppm error to facilitate elemental formulae predictions. Singly protonated product with exact m/z and expected elemental formula matching the singly protonated form of 3-(2-aminoethyl)-5,7-dimethyl-1H-indol-4-amine, having chemical formula (VI): 
     
       
         
         
             
             
         
       
     
     eluted at 2.9 minutes (EIC, see:  FIG.  12 A ). Although peak splitting can be minimized through the use of DMSO as injection solvent (Kaufman and Jegle 2005, Agilent Technologies Technical Bulletin 5989-2485EN), this phenomenon persisted owing to ion pairing effects between matrix components (Tarafder et al. 2010, J Chromatogr A 1217:7065-7073). 
     As per standard procedures (Menéndez-Perdomo et al. 2021, Mass Spectrom 56: 34683) further analysis using high energy collisions (HCD) was achieved in a dedicated, post-LTQ, nitrogen collision cell. Orbitrap-based, HR fragment detection was employed (normalized collision energy, NCE 35), enabling opportunity to assign elemental formulae to subsequent diagnostic ion species characteristic of the targeted aminated psilocybin derivative with formula (VI) as follows ( FIG.  12 B , Table 1) (Servillo L et al., 2013, J. Agric. Chem. 61: 5156-5162).

     Example 3—Biochemical Synthesis of a Fifth Aminated Psilocybin Derivative 
       Escherichia coli  strain Ec-1 was used to biosynthesize aminated psilocybin derivative with formula (XIV) from aminated indole feedstock. The construction of Ec-1 is described in Example 2. Scaled-up culturing and material storage of engineered  E. coli  was conducted as described in Example 2, except that 6-methyl-1H-indol-4-ylamine (Combi-Blocks, www.combi-blocks.com) was used in place of 5,7-dimethyl-1H-indol-4-ylamine. To assess product, high-resolution LC-HESI-LTQ-Orbitrap-XL MS analysis was conducted as described in Example 2.

     Example 4—Biochemical Synthesis of a Sixth Aminated Psilocybin Derivative 
       Escherichia coli  strain Ec-2 was used to biosynthesize aminated psilocybin derivative, where the amino group terminating the 2-carbon aliphatic side chain was conjugated to an acetyl group. Ec-2 was constructed using the same method as for Ec-1 (see: Example 2), except that an additional plasmid was assembled and transformed into cells along with pETM6-H 10 -TmTrpB-2F3-V5-BaTDC-FLAG. This additional plasmid encoded a promiscuous and efficient  Streptomyces griseofuscus  N-acetyltransferase enzyme named PsmF (SEQ. ID NO: 5). This additional plasmid was assembled as follows: from plasmid pCDM4 (SEQ. ID NO: 1), the plasmid pCDM4-PsmF-FLAG was created by inserting an in-frame, C-terminally FLAG-tagged (SEQ. ID NO: 2, SEQ. ID NO: 3) PsmF gene (SEQ. ID NO: 4, SEQ. ID NO: 5) into the NdeI/XhoI site of pCDM4. The two target plasmids pCDM4-PsmF-FLAG and pETM6-H10-TmTrpB-2F3-V5-BaTDC-FLAG were transformed into BL21 (DE3) cells, and antibiotics ampicillin plus streptomycin were used to select for the correct clones containing both plasmids. Scaled up culturing, analysis, purification, toxicology, and pharmacological testing were performed as described in Example 2, except that 1H-indol-7-ylamine (Combi-Blocks, www.combi-blocks.com) was used in place of 5,7-dimethyl-1H-indol-4-ylamine. Purification of the target product was achieved as follows: to 0.75 L of  E. coli  culture, 10M NaOH solution was added until the pH reached ˜7. The culture was then extracted by ethyl acetate (4×500 ml). The organic layer was dried over Na 2 SO 4 , followed by concentration under reduced pressure. The residue was purified by flash chromatography on silica gel methanol-dichloromethane (2-&gt;4%) as eluent, to give the compound as light yellow solid (15 mg). NMR and HRMS data were as follows:  1 H NMR (400 MHz, CD 3 OD): δ=1.91 (s, 3H), 2.22 (s, 3H), 2.93 (t, J=6.9 Hz, 2H), 3.46 (t, J=7.2 Hz, 2H), 6.99 (t, J=7.8 Hz, 1H), 7.10 (m, 2H), 7.44 (dd, J=7.9, 1.0 Hz, 1H). Selective  13 C NMR (100 MHz, CD 3 OD): δ=21.2, 21.8, 24.7, 40.0, 112.5, 115.2, 115.8, 118.3, 122.1, 122.3, 129.4, 170.5, 171.8. HRMS (ESI) m/z: calcd. for C 14 H 17 N 3 O 2  [M+H] +  260.1394, found 260.1392. Purity was assessed at 95%. This characterization confirmed a structure corresponding to compound (XIII): 
     
       
         
         
             
             
         
       
     
     Assessment of Cell Viability Upon Treatment of Aldehyde Psilocybin Derivative 
     Cell viability was assessed as described for Example 1, except the compound with formula (XIII) was evaluated in place of the compounds with formulae (IX) and (XII).  FIG.  11 C  shows PrestoBlue assay results for compound with formula (XIII), depicted on the x-axis as “XIII”. 
     Radioligand Receptor Binding Assays. 
     Activity at 5-HT 2A  receptor was assessed as described for Example 1, except the compound with formula (XIII) was evaluated in place of the compounds with formulae (IX) and (XII).  FIG.  11 H  shows radioligand competition assay results for compound with formula (XIII), depicted on the x-axis simply as “XIII”. 
     Example 5—Biochemical Synthesis of a Seventh Aminated Psilocybin Derivative 
       Escherichia coli  strain Ec-2 was used to biosynthesize aminated psilocybin derivative with formula (VII) from aminated indole feedstock. The construction of Ec-2 is described in Example 4. Scaled-up culturing and material storage of engineered  E. coli  was conducted as described in Example 2. To assess product, high-resolution LC-HESI-LTQ-Orbitrap-XL MS analysis was conducted as described in Example 2. Singly protonated product with exact m/z and expected elemental formula matching the singly protonated form of N-[2-(4-amino-5,7-dimethyl-1H-indol-3-yl)ethyl]acetamide having chemical formula (VII): 
     
       
         
         
             
             
         
       
     
     eluted at 2.9 minutes (EIC, see:  FIG.  14 A ). Although peak splitting can be minimized through the use of DMSO as injection solvent (Kaufman and Jegle 2005, Agilent Technologies Technical Bulletin 5989-2485EN), this phenomenon persisted owing to ion pairing effects between matrix components (Tarafder et al 2010, J Chromatogr A 1217:7065-7073). 
     As per standard procedures (Menéndez-Perdomo et al. 2021, Mass Spectrom 56: 34683) high energy collisions (HCD) were achieved in a dedicated, post-LTQ, nitrogen collision cell. Orbitrap-based, HR fragment detection was employed (normalized collision energy, NCE 35), enabling opportunity to assign elemental formulae to subsequent diagnostic ion species characteristic of a compound of formula (VII), as follows ( FIG.  14 B , Table 111) (Servillo L. et al, 2013, J.

     Example 10—Biochemical Synthesis of a Twelfth Aminated Psilocybin Derivative 
       Escherichia coli  strain Ec-3 was used to biosynthesize aminated psilocybin derivative, where the amino group terminating the 2-carbon aliphatic side chain was singly methylated. Ec-3 was constructed using the same method as for Ec-1 (see: Example 2), except that an additional plasmid was assembled and transformed into cells along with pETM6-H10-TmTrpB-2F3-V5-BaTDC-FLAG. This additional plasmid encoded a promiscuous and efficient  Rhinella marina  N-methyltransferase enzyme named RmNMT (SEQ. ID NO: 14). This additional plasmid was assembled as follows: from plasmid pCDM4 (SEQ. ID NO: 1), the plasmid pCDM4-RmNMT-FLAG was created by inserting an in-frame, C-terminally FLAG-tagged (SEQ. ID NO: 2, SEQ. ID NO: 3) RmNMT gene (SEQ. ID NO: 13) into the NdeI/XhoI site of pCDM4. The two target plasmids pCDM4-RmNMT-FLAG and pETM6-H 10 -TmTrpB-2F3-V5-BaTDC-FLAG were transformed into BL21 (DE3) cells, and antibiotics ampicillin plus streptomycin were used to select for the correct clones containing both plasmids. Scaled up culturing and analysis were performed as described in Example 2, except that 6-methyl-1H-indol-4-ylamine (BLDPharm, www.bldpharm.com) was used in place of 5,7-dimethyl-1H-indol-4-ylamine. To assess product, high-resolution LC-HESI-LTQ-Orbitrap-XL MS analysis was conducted as described in Example 2. Singly protonated product with exact m/z and expected elemental formula matching the singly protonated form of 6-methyl-3-[2-(methylamino)ethyl]-1H-indol-4-amine having chemical formula (XVII): 
     
       
         
         
             
             
         
       
     
     eluted at 2.4 minutes (EIC, see:  FIG.  19   ). Although peak splitting and poor peak shape can be minimized through the use of DMSO as injection solvent (Kaufman and Jegle 2005, Agilent Technologies Technical Bulletin 5989-2485EN), this phenomenon persisted owing to ion pairing effects between matrix components (Tarafder et al. 2010, J Chromatogr A 1217:7065-7073).
