     FIELD OF THE INVENTION 
     This invention relates to crystalline N-methyl tryptamine derivatives, compositions containing those crystalline forms and their methods of using the same. The crystalline N-methyl tryptamine derivatives according to the disclosure include crystalline N-methyl-N-propyltryptamine (MPT), crystalline N-methyl-N-isopropyltryptammonium fumarate (MiPT fumarate), crystalline 4-hydroxy-N-methyl-N-isopropyltryptammonium fumarate monohydrate (HO-MiPT fumarate monohydrate), and/or crystalline [2-(1H-indol-3-yl)ethyl]trimethylazanium iodide (N,N,N-trimethyltryptammonium iodide or TMT iodide), such as crystalline form 1 of TMT iodide. 
     BACKGROUND OF THE INVENTION 
     N-methyl-N-propyltryptamine (MPT) is a structural analog of N,N-dimethyltryptamine (DMT), which is a well-known ‘psychedelic’ molecule found in a variety of naturally occurring organisms, including plants, animals, and fungi, including mushrooms. In humans, DMT is the only known endogenous mammalian N,N-dimethylated trace amine (Fontanilla et al., 2009). Naturally occurring tryptamines (e.g. DMT, psilocybin, 5-methoxy-N,N-dimethyltryptamine) and their synthetic derivatives (e.g. psilacetin, MPT) have garnered considerable attention of late due to new evidence demonstrating their efficacy in treating mood (e.g. anxiety and depression) and post-traumatic stress disorders (PTSDs) (Aixala&#39; et al., 2018; Cameron et al., 2019). 
     Psilocybin, isolated from the so-called “magic” mushrooms, is perhaps the best-known prodrug of the serotonin 2a agonist psilocin (Nichols, 2016). Recent studies indicate that psilocin (and its prodrugs like psilocybin and psilacetin) could provide effective treatment for mood disorders, end-of-life anxiety, addiction, and PTSD (Carhart-Harris et al., 2016; Johnson &amp; Griffiths, 2017). However, the long duration of action of psilocin and its prodrugs can result in practical challenges for both patients and clinicians (Passie et al., 2002). Accordingly, the mental health industry would benefit from exploring alternative tryptamine treatment options that provide similar therapeutic benefits while having a shorter duration of action. 
     While the synthesis of DMT was first reported in 1931 (Manske, 1931), the first literature report of MPT appeared in 2005 (Brandt et al., 2005) and it has not undergone significant study. Prior to this work, however, no crystalline form of MPT has been reported. There is a need therefore to develop a form of MPT that allows for development as an active pharmaceutical ingredient (an API) and for pharmaceutical compositions containing that form of MPT. This disclosure answers such needs. 
     Although therapeutic efficacy is the primary concern for an active pharmaceutical ingredient (API), the salt and solid state form (i.e., the crystalline or amorphous form) of a drug candidate can be critical to its pharmacological properties, such as bioavailability, and to its development as a viable API. Recently, crystalline forms of API&#39;s have been used to alter the physicochemical properties of an API. Each crystalline form of a drug candidate can have different solid state (physical and chemical) properties. The differences in physical properties exhibited by a novel solid form of an API (such as a cocrystal or polymorph of the original therapeutic compound) affect pharmaceutical parameters such as storage stability, compressibility and density (important in formulation and product manufacturing), and solubility and dissolution rates (important factors in determining bioavailability). Because these practical physical properties are influenced by the solid-state properties of the crystalline form of the API, they can significantly impact the selection of a compound as an API, the ultimate pharmaceutical dosage form, the optimization of manufacturing processes, and absorption in the body. Moreover, finding the most adequate solid-state form for further drug development can reduce the time and the cost of that development. 
     Obtaining crystalline forms of an API is extremely useful in drug development. It permits better characterization of the drug candidate&#39;s chemical and physical properties. Crystalline forms often have better chemical and physical properties than the API in its amorphous state. Such crystalline forms may possess more favorable pharmaceutical and pharmacological properties or be easier to process.

     An “effective amount” or a “therapeutically effective amount” of a crystalline N-methyl tryptamine derivative according to the disclosure is generally in the range of about 0.1 to about 100 mg daily (oral dose), of about 0.1 to about 50 mg daily (oral dose) of about 0.25 to about 25 mg daily (oral dose), of about 0.1 to about 5 mg daily (oral dose) or of about 0.5 to about 2.5 mg daily (oral dose). The actual amount required for treatment of any particular patient may depend upon a variety of factors including, for example, the disease being treated and its severity; the specific pharmaceutical composition employed; the age, body weight, general health, sex, and diet of the patient; the mode of administration; the time of administration; the route of administration; and the rate of excretion; the duration of the treatment; any drugs used in combination or coincidental with the specific compound employed; and other such factors well known in the medical arts. These factors are discussed in Goodman and Gilman&#39;s “The Pharmacological Basis of Therapeutics,” Tenth Edition, A. Gilman, J. Hardman and L. Limbird, eds., McGraw-Hill Press, 155-173 (2001), which is incorporated herein by reference. A crystalline N-methyl tryptamine derivative according to the disclosure, compositions and pharmaceutical compositions containing it may be used in combination with other agents that are generally administered to a patient being treated for psychological and other disorders discussed above. They may also be co-formulated with one or more of such agents in a single pharmaceutical composition. 
     Depending on the type of composition or pharmaceutical composition, the excipient or pharmaceutically acceptable carrier may be chosen from any one or a combination of carriers known in the art. The choice of the pharmaceutically acceptable carrier depends upon the pharmaceutical form and the desired method of administration to be used. Preferred carriers include those that do not substantially alter the crystalline N-methyl tryptamine derivative or produce undesirable biological effects or otherwise interact in a deleterious manner with any other component(s) of the pharmaceutical composition. 
     The compositions or pharmaceutical compositions of the disclosure may be prepared by methods know in the pharmaceutical formulation art, for example, see Remington&#39;s Pharmaceutical Sciences, 18th Ed., (Mack Publishing Company, Easton, Pa., 1990), which is incorporated herein by reference. In a solid dosage form, the crystalline N-methyl tryptamine derivative may be admixed with at least one pharmaceutically acceptable excipient such as, for example, sodium citrate or dicalcium phosphate or (a) fillers or extenders, such as, for example, starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders, such as, for example, cellulose derivatives, starch, alginates, gelatin, polyvinylpyrrolidone, sucrose, and gum acacia, (c) humectants, such as, for example, glycerol, (d) disintegrating agents, such as, for example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, croscarmellose sodium, complex silicates, and sodium carbonate, (e) solution retarders, such as, for example, paraffin, (f) absorption accelerators, such as, for example, quaternary ammonium compounds, (g) wetting agents, such as, for example, cetyl alcohol, and glycerol monostearate, magnesium stearate and the like (h) adsorbents, such as, for example, kaolin and bentonite, and (i) lubricants, such as, for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents. 
     Excipients or pharmaceutically acceptable adjuvants known in the formulation art may also be used in the pharmaceutical compositions of the disclosure. These include, but are not limited to, preserving, wetting, suspending, sweetening, flavoring, perfuming, emulsifying, and dispensing agents. Prevention of the action of microorganisms may be ensured by inclusion of various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride, and the like. If desired, a composition or a pharmaceutical composition of the disclosure may also contain minor amounts of auxiliary substances such as wetting or emulsifying agents, pH buffering agents, antioxidants, and the like, such as, for example, citric acid, sorbitan monolaurate, triethanolamine oleate, butylated hydroxytoluene, etc. 
     Solid dosage forms as described above may be prepared with coatings and shells, such as enteric coatings and others well known in the art. They may contain pacifying agents and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Non-limiting examples of embedded compositions that may be used are polymeric substances and waxes. The active compounds may also be in microencapsulated form, if appropriate, with one or more of the above-mentioned excipients. 
     Suspensions, in addition to the active compounds, may contain suspending agents, such as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, or mixtures of these substances, and the like. 
     Solid dosage forms for oral administration, which includes capsules, tablets, pills, powders, and granules, may be used. In such solid dosage forms, the active compound may be mixed with at least one inert, pharmaceutically acceptable excipient (also known as a pharmaceutically acceptable carrier). 
     Administration of a crystalline N-methyl tryptamine derivative according to the disclosure in pure form, with a permeation enhancer, with stabilizers (e.g. antioxidants), or in an appropriate pharmaceutical composition may be carried out via any of the accepted modes of administration or agents for serving similar utilities. Thus, administration may be, for example, orally, buccally, nasally, parenterally (intravenous, intramuscular, or subcutaneous), topically, transdermally, intravaginally, intravesically, or intrasystemically, in the form of solid, semi-solid, lyophilized powder, liquid dosage forms, such as, for example, tablets, suppositories, pills, soft elastic and hard gelatin capsules, powders, suspensions, or aerosols, or the like, such as, for example, in unit dosage forms suitable for simple administration of precise dosages. One route of administration may be oral administration, using a convenient daily dosage regimen that can be adjusted according to the degree of severity of the disease-state to be treated. 
     EXAMPLES 
     Single Crystal X-Ray Diffraction (SCXRD) Characterization: 
     Data were collected on a Bruker D8 Venture CMOS Diffractometer equipped with an Oxford Cryosystems Cryostream cooling device and using Mo Kα radiation. Structures were solved using the Bruker SHELXTL program and refined with the SHELXTL program as part of the Bruker SHELXTL suite, or OLEX2 software. Unless otherwise stated, hydrogen atoms attached to carbon were placed geometrically and allowed to refine with a riding isotropic displacement parameter. Hydrogen atoms attached to a heteroatom were located in a difference Fourier synthesis and were allowed to refine freely with an isotropic displacement parameter.

     The molecular structure of crystalline MPT according to the disclosure is shown in  FIG.  1    with atomic labelling. Displacement ellipsoids are drawn at the 50% probability level.  FIG.  2    shows the crystal packing of crystalline MPT, viewed along the c axis. The N—H—N hydrogen bonds are shown as dashed lines. Displacement ellipsoids are drawn at the 50% probability level. H atoms not involved in hydrogen bonding have been omitted for clarity. 
     In the solid-state structure of MPT, there is a single molecule in the symmetric unit, with an indole group that demonstrates a mean deviation from planarity of 0.015 Å ( FIG.  1   ). The metrical parameters are consistent with the previously reported structure of DMT (Falkenberg, 1972) and other dialkyltryptamines (Chadeayne et al., 2019a,b; Petcher &amp; Weber, 1974; Weber &amp; Petcher, 1974). The tryptamine molecules are held together in an infinite one-dimensional chain along [010] through N—HN hydrogen bonds connecting the indole N atom to the mine N atom (Table 1,  FIG.  2   ). In the structure of N,N-dimethyltryptamine (DMT), there are similar hydrogen bonds, but they hold molecules together as dimers rather than in a chain. There are no π-π interactions observed in the crystalline DMT structure. 
       FIG.  3    is a simulated X-ray powder diffraction pattern (XRPD) for crystalline MPT generated from its single crystal data. Characteristic peaks identifying crystalline MPT include peaks at 11.7, 13.4 and 19.4° 2θ±0.2° 2θ.

     The molecular structure of crystalline MiPT fumarate according to the disclosure is shown in  FIG.  4    with atomic labelling, and the hydrogen bonding of the fumarate ion in the structure of crystalline MiPT fumarate is shown in  FIG.  5   . Displacement ellipsoids are drawn at the 50% probability level. The symmetric unit contains one N-methyl-N-isopropyltryptammonium (C 14 H 21 N 2   + ) cation and one 3-carboxyacrylate (C 4 H 3 O 4   − ) anion. The indole ring system of the cation is near planar with an r.m.s. deviation from planarity of 0.006 Å. The singly protonated fumarate anion is in the trans configuration and is slightly distorted from planarity with an r.m.s. deviation of 0.133 Å and a carboxylate twist angle of 18.370 (5). The N-methyl-N-isopropylammonium group is disordered over two orientations in a 0.630 (3):0.370 (3) ratio. 
     In the extended crystal structure of MiPT fumarate, the N-methyl-N-isopropylamine and fumarate ions are linked into infinite two-dimensional networks lying parallel to the (010) plane through N—H—O and O—H—O hydrogen bonds. The proton of themmonium cation forms a hydrogen bond with one of the oxygen atoms of the deprotonated —CO 2   −  group of the 3-carboxyacrylate ion. The carboxylic acid proton forms a hydrogen bond with an oxygen atom of an adjacent 3-carboxyacrylate anion. The N-H grouping of the indole ring also hydrogen bonds to one of the oxygen atoms of the 3-carboxyacrylate anion. 
       FIG.  6    shows the crystal packing of crystalline MiPT fumarate, viewed along the axis. The hydrogen bonds are shown as dashed lines. Displacement ellipsoids are drawn at the 50% probability level. H atoms not involved in hydrogen bonding have been omitted for clarity. 
       FIG.  7    is a simulated X-ray powder diffraction pattern (XRPD) for crystalline MiPT fumarate generated from its single crystal data. Characteristic peaks identifying crystalline MiPT include peaks at 11.9, 14.9 and 16.9° 2θ±0.2° 2θ. 
     The molecular structure of crystalline HO-MiPT fumarate monohydrate according to the disclosure is shown in  FIG.  8    with atomic labelling, and the hydrogen bonding of the fumarate ion in the structure of crystalline MiPT fumarate is shown in  FIG.  9   . 
     Displacement ellipsoids are drawn at the 50% probability level. The symmetric unit contains one 4-hydroxy-N-methyl-N-isopropyltryptammonium (C 14 H 21 N 2 O + ) cation, one 3-carboxyacrylate anion and one water molecule of crystallization. The indole ring system of the cation is close to planar with an r.m.s. deviation of 0.021 Å. The singly protonated fumarate anion is also near planar with an r.m.s. deviation of 0.049 Å. The N-methyl-N isopropylammonium group shows a similar disorder to the MiPT structure over two orientations in a 0.775 (5):0.225 (5) ratio. 
     In the structure of 4-HO-MiPT fumarate monohydrate, there are N—H—O and O—H—O hydrogen bonds that link together the cations and anions as well as the water molecules of crystallization. The result is a two-dimensional network lying parallel to the (201) plane. The proton of themmonium cation forms a bifurcated N—H—(O,O) hydrogen bond with the deprotonated —CO 2  group of the 3-carboxyacrylate ion. The hydrogen of the hydroxy group also hydrogen bonds to the same oxygen atom of thenion. The carboxylic acid proton hydrogen bonds with a water molecule in the structure. Two other water molecules form hydrogen bonds with two different oxygen atoms of thenion. 
       FIG.  10    shows the crystal packing of crystalline HO-MiPT fumarate monohydrate, viewed along the b axis. The hydrogen bonds are shown as dashed lines. Displacement ellipsoids are drawn at the 50% probability level. H atoms not involved in hydrogen bonding have been omitted for clarity. 
       FIG.  11    is a simulated X-ray powder diffraction pattern (XRPD) for HO-MiPT fumarate monohydrate generated from its single crystal data. Characteristic peaks identifying crystalline HO-MiPT include peaks at 7.2, 13.3 and 18.0° 2θ±0.2° 2θ. 
     The MiPT structure described above is a derivative of DMT (N,N-dimethyltryptamine), which has been structurally characterized (Falkenberg, 1972), as well as its close derivative MPT, N-methyl-N-propyltryptamine (Chadeayne et al. 2019b). In both cases, these were crystallized as free bases, while MiPT is the fumarate salt. In the case of 4-HO-MiPT, the most closely related molecule is psilocin, which has been structurally characterized (Petcher &amp; Weber, 1974), as well as psilocybin (Weber &amp; Petcher, 1974). Psilocin was reported as the free base and psilocybin was reported as a zwitterionic molecule, while the structure of 4-HO-MiPT reported here is the hydrated fumarate salt. Two different ionic structures of the 4-acetoxy derivative of DMT have been reported as fumarate salts (Chadeayne et al. 2019a,c). The metrical parameters of the tryptammonium cations for MiPT and 4-HOMiPT are consistent with those of the other tryptammonium structures reported. 
     Example 3: Preparation and Characterization of Crystalline Form 1 of N,N,N-Trimethyltryptammonium Iodide (TMT Iodide) 
     Synthesis 
     162 mg of tryptamine, 322 mg of sodium carbonate and 0.5 mL of iodomethane were dissolved in 10 mL of isopropanol. The solution was heated at reflux for twelve hours under an atmosphere of nitrogen. Solvent was removed in vacuo to yield a yellow powder. 
     Crystallization 
     Single crystals suitable for X-ray diffraction were grown from the slow evaporation of an acetone/ethanol solution. 
     Single Crystal Characterization 
     The single crystal data and structure refinement parameters for the crystalline form 1 structure of TMT iodide are reported in Table 5, below.

     Simulated Powder X-Ray Diffraction (PXRD) Pattern 
       FIG.  14    shows a simulated X-ray powder diffraction pattern (XRPD) for crystalline form 1 of TMT iodide generated from its single crystal data. Table 6 lists the angles, °2θ 0.2° 2θ, and d-spacing of the peaks identified in the experimental XRPD pattern of  FIG.  14   . The entire list of peaks, or a subset thereof, may be sufficient to characterize the cocrystal. For example, the cocrystal may be characterized by at least two peaks selected from the peaks at 10.19, 13.86, and 16.89° 2θ±0.2° 2θ or their corresponding d-spacing as well as by an XRPD pattern substantially similar to  FIG.  14   .
