## Background
The present invention relates to pyrazolo[1,5-a][1,3,5]triazine derivatives and/or pharmaceutically acceptable salts thereof, the use of these derivatives as pharmaceutically active agents, especially for the prophylaxis and/or treatment of cell proliferative diseases, inflammatory and immunological diseases, cardiovascular diseases and infectious diseases. Furthermore, the present invention is directed towards pharmaceutical composition containing at least one of the pyrazolo[1,5-a][1,3,5]triazine derivatives and/or pharmaceutically acceptable salts thereof.
Cyclin-dependent kinase (CDK) family members that trigger passage through the cell cycle are being considered as attractive therapeutic targets, especially for cancer. CDK family members that control other processes such as transcription and RNA processing have caught less attention so far, although experimental evidence for their involvement in different pathological processes is emerging. The CDK-activating kinase, or CAK complex, consists of CDK7, cyclin H, and MAT1. As part of CAK, CDK7 phosphorylates other CDKs, an essential step for their activation. Therefore CDK7 is required for cell cycle progression, which suggests that CDK7 is a target for cancer therapy. As the kinase subunit of TFIIH, CDK7 participates in basal transcription by phosphorylating the carboxy-terminal domain of the largest subunit of RNA polymerase II. As a general regulator of transcription, CDK7 is a therapeutic target for treatment of diseases like inflammation, virus replication such as HIV, EBV, and HCV, cancer and cardiac hypertrophy.
HIV-1 gene expression is regulated by a viral transactivator protein (Tat) which induces transcriptional elongation of HIV-1 long tandem repeat. This induction requires hyperphosphorylation of the C-terminal domain repeats of RNA polymerase II. To achieve said hyperphosphorylation, Tat stimulates CTD kinases associated with general transcription factors of the promoter complex, specifically TFIIH-associated CDK7. (Nekhai et al.; Biochem. J. (2002) 364, 649-657). Also the inventors of U.S. Pat. No. 615,968 describe that Tat binds to CDK7 and that this interaction increases the ability of CAK to phosphorylate CTD. The authors of U.S. Pat. No. 615,968 further disclose that the transcriptional activation by Tat is dependent upon the kinase activity of CDK07. Additionally, Young Kyeung Kim and colleagues conclude that the recruitment and activation of TFIIH represents a rate-limiting step for the emergence of HIV from latency (Young Kyeung Kim, EMBO I (2006) 25, 3596-3604).
Levels of CDK7 and CDK9, as well as other components of the kinase complexes, MAT-1/cyclin H are upregulated during Human cytomegalovirus infection. In addition, there is an increase in the kinase activities of CDK7 and CDK9 (Tamrakar et al., Journal of Virology, 2005, 79; 15477-15493).
Many antiviral drugs target viral proteins. These have the disadvantage that viruses often develop resistance against these drugs. Antiviral drugs targeting cellular proteins essential for viral process, like CDK7, could bypass this disadvantage. These drugs may further be effective in treating several unrelated viruses and their effects should be additive to traditional antiviral agents. Inhibitors of CDK7, which has its dual function of CDK-activating kinase and transcription regulation is very effective in the treatment of several viruses.
It is object of the present invention to provide compounds and/or pharmaceutically acceptable salts thereof which can be used as pharmaceutically active agents, especially for prophylaxis and/or treatment of cell proliferative diseases, inflammatory diseases, immunological diseases, cardiovascular diseases and infectious diseases, as well as compositions comprising at least one of those compounds and/or pharmaceutically acceptable salts thereof as pharmaceutically active ingredients.
This object is solved by the compounds and/or their pharmaceutically acceptable salts according to independent claim 1, the compounds of the present invention for use as pharmaceutically active agents, the use of the compounds of the present invention for the preparation of a pharmaceutical composition for the prophylaxis and/or treatment of infectious diseases, including opportunistic diseases, immunological diseases, autoimmune diseases, cardiovascular diseases, cell proliferative diseases, inflammation, erectile dysfunction and stroke according to independent claim 6, the use of compounds according to the present invention as inhibitors for the protein kinase CDK7.
Further advantageous features, aspects and details of the invention are evident from the dependent claims, the description, the examples and the drawings.

If R11 and R12 are joined together, they form a ring system and especially a four-membered, a five-membered or a six-membered ring system together with the atoms to which they are attached. Preferred ring systems are five-membered cyclocarbamates, five-membered cyclic ureas, five-membered cyclic guanidines, six-membered cyclocarbamates, six-membered cyclic ureas, six-membered cyclic guanidines, pyrrolidones, pyridones, piperidinones, imidazoles, imidazolines, pyrrolines, imidazolidin-2-ones.
R3 together with R4 can form a carbocylic or heterocyclic 4-, 5-, 6- or 7-membered ring with the two carbon atoms of the benzo ring to which R3 and R4 are attached and that 4-, 5-, 6- or 7-membered ring can be partly saturated or unsaturated and can be substituted with 1 to 4 substituents selected from Z1, Z2, Z3 and Z4. Z1 and Z2 if attached to the same carbon atom can together represent ═O to form a carbonyl group with the carbon atom to which Z1 and Z2 are attached, so that so a ring has one carbonyl group and may comprise one or two further residues which are not allowed to form a carbonyl group together.
Partly saturated as used herein means that the ring system additionally formed by joining R3 with R4 when taken alone already bears one double bond originated in the phenyl ring to which R3 and R4 are attached. Thus, since R3 and R4 are attached to a phenyl ring a double bond equivalent exists between the two carbon atoms that bear R3 and R4, respectively. Therefore, the person skilled in the art will understand that the ring system formed when R3 and R4 are joined together can not be a saturated ring system, but a partly saturated ring system when the moiety introduces at least one saturated atom or two subsequent saturated bonds.

R11, R12, R13, R14 and R15 represent independently of each other —H, linear or branched C1-C8-alkyl, C3-C8-cycloalkyl, C1-C9-heterocyclyl, linear or branched C2-C8-alkenyl, linear or branched C2-C8-alkynyl, C6-C14-aryl, C1-C10-heteroaryl, wherein the afore-mentioned residues can be substituted with 1 to 5 substituents selected from Z8, Z9, Z10, Z11 and Z12.
R11, R12, R13, R14 and R15 preferably represent independently of each other —H, methyl, isopropyl and pyrrolidinyl.
As used herein C1-C4-alkyl refers to —CH3, —CF3, —C2H5, —C3H7, —C4H9, —CH(CH3)2, —CH2—CH(CH3)2, —CH(CH3)—C2H5, —C(CH3)3, —C2F5, wherein these residues can be substituted with 1, 2 or 3 substituents selected from Z8, Z9 and Z10. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z8, Z9 and Z10.
As used herein linear C1-C8-alkyl refers to —CH3, —C2H5, —C3H7, —C4H9, —C5—H11, —C6H13, —C7H15, —C8H17, —CH2-Ph, —CH2—CH2-Ph, wherein these residues can be substituted with 1 to 5 substituents selected from Z8, Z9, Z10, Z11 and Z12. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z8, Z9, Z10, Z11 or Z12. Moreover it is clear to a skilled person that only these hydrogen atoms which are present in the residue can be replaced by the substituents Z8, Z9, Z10, Z11 and Z12. Thus, since the methyl group has only three hydrogen atoms, only three hydrogen atoms can be replaced by three substituents selected from Z8, Z9, Z10, Z11 and Z12. For the definitions used herein the alkylaryl group —CH2-Ph (benzyl group) and the —CH2—CH2-Ph group should fall under the definition “linear C1-C8-alkyl”. Thus in case one hydrogen is substituted by an amino group, the residue —C3H6—NH2 would also fall under the definition “linear C1-C8-alkyl”.
The term “substituted” as used herein further indicates that the substituted residue like “substituted linear C1-C8-alkyl” does definitely have at least one substituent (at least one Z substituent) while the residue without the term “substituted” like “linear C1-C8-alkyl” can have at least one substituent. Consequently, if the term “substituted” is not used in relation to a residue this does not indicate that this residue is unsubstituted.
Examples of preferred substituted linear C1-C8-alkyl residues are —CH2—OH, —CH2—O—CH3, —CH2—OCF3, —CF3, —CH2Cl, —CH2CH2Cl, —CH2CH2—OCF3, and —CH2-Ph.

The carbon atom number of C1-C8 refers only to the carbon atoms of the alkyl residue and does not include the carbon atoms of the substituents Z8 to Z12.
Examples of preferred substituted branched C1-C8-alkyl or preferably branched C3-C8-alkyl residues are —CH(CH2Cl)2, —CH(CH3)—C2H4—OCF3, —C(CH3)2—CF3, —COCH3(CH3)2—, —CHCH3Cl, —CH2—CHCH3NH2, —CClCH3—C2H5, —C(CH3)2OH, —CClCH3—C3H7, —CH2—C(OH)(CH3)—C2H5, —CH(CH3)—CHCH3Cl, —C(CH3)2—C2H4NH2, —CH2—C(CH3)2OH, —CNH2(C2H5)2, —C2H4—COH(CH3)2, —C3H6—COH(CH3)2.
As defined above, the term “substituted” in “substituted branched C3-C8-alkyl” indicated that definitely at least one substituent is present while the term “branched C3-C8-alkyl” only defines that the carbon chain is branched but does not exclude further substituents. Consequently it is stated above that the “branched C3-C8-alkyl” residues can be substituted with 1 to 5 substituents selected from Z8, Z9, Z10, Z11 and Z12. Thus, for instance, the “substituted branched C3-C8-alkyl” residues are a subgroup of the “branched C3-C8-alkyl” residues. The same applies to the other residues which are mentioned with the term “substituted” and without the term “substituted”.
As used herein, C3-C8-cycloalkyl refers to cyclo-C3H5, cyclo-C4H7, cyclo-C5H9, cyclo-C6H11, cyclo-C7H13, and cyclo-C8H15, wherein these residues can be substituted with 1 to 5 substituents selected from Z8, Z9, Z10, Z11 and Z12. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z8, Z9, Z10, Z11 or Z12. The carbon atom number of C3-C8 refers only to the carbon atoms of the cycloalkyl residue and does not include the carbon atoms of the substituents Z8 to Z12.

wherein these residues can be substituted with 1 to 5 substituents selected from Z8, Z9, Z10, Z11 and Z12. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z8, Z9, Z10, Z11 or Z12. Moreover, it is clear to a skilled person that only these hydrogen atoms which are present in the residue can be replaced by the substituents Z8, Z9, Z10, Z11 and Z12. Thus, since the vinyl group has only three hydrogen atoms, only three hydrogen atoms can be replaced by three substituents selected from Z8, Z9, Z10, Z11 and Z12. The carbon atom number of C2-C8 refers only to the carbon atoms of the alkenyl residue and does not include the carbon atoms of the substituents Z8 to Z12. For the definitions used herein, the group —CH═CH-Ph should fall under the term “linear or branched C2-C8-alkenyl”.

If the spiroheterocyclyl residue contains a nitrogen atom which is substituted by one of the substituents Z5, Z6 and Z7, said Z substituent represents R12. Thus the indication “N1” refers to the group




of the spiro ring system. If the spiroheterocyclyl residue contains two nitrogen atoms which are both substituted by one of the substituents Z5, Z6 and Z7, the first Z substituent represents R11 and the second Z substituent represents R12. Thus the indication “N2” refers to the groups and

As used herein, the term “C5-C14-spironitrogenheterocyclyl” refers to spiro substituents with 5 to 14 carbon atoms and at least one nitrogen atom and optionally further heteroatoms such as N, S, O, S═O, SO2 in the spiro cyclus and refers preferably to the C5-C14-spiroheterocyclyl residues as disclosed above, wherein one heteroatom is nitrogen. The C5-C14-spironitrogenheterocyclyl residue is linked through the at least one nitrogen spiro cyclus atom to the rest of the molecule. Moreover the C5-C14-spironitrogenheterocyclyl residue can be substituted with 1 to 3 substituents selected from Z5, Z6 and Z7.
The term “bridging spiroheterocyclyl” refers to a spiroheterocyclyl residue as disclosed above, which is further bonded to a second substituent independent from any optional substitution with substituents Z1, Z2, Z3 or Z4. Thus, in a “bridging spiroheterocycly” two hydrogen atoms are replaced by residues rendering the “bridging spiroheterocyclyl” a di-yl moiety. Further, the “bridging spiroheterocyclyl” binds the two different residues with two different atoms of the spiroheterocyclyl skeleton, thereby preventing a substitution pattern wherein the two residues are bonded to the same atom. The “bridging spiroheterocyclyl” can be substituted with 1 to 4 substituents selected from Z1, Z2, Z3 or Z4. It is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z1, Z2, Z3 or Z4. Further, it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z1, Z2, Z3 or Z4. Moreover, it is clear to a skilled person that only these hydrogen atoms which are present in the “bridging spiroheterocyclyl” group can be replaced by the substituents Z1, Z2, Z3 and Z4.
The person skilled in the art will understand that when R2 being —(CH2)a-(Q)b-(CH2)c-(G1)d-(CH2)e-(G2)f-CH2—R9 and for example G1 represents “a bridging spiroheterocyclyl” (d=1), then this “bridging spiroheterocyclyl” is attached to a first part of R2, for instance —NR15—CH2— in case a=0, b=c=1, Q=—NR5—, and a second part of R2, for instance —C4H8—R9 in case f=0 and e=3. Thus, “a bridging spiroheterocyclyl” is attached to two different residues redering it a di-yl residue.

As used herein, the term “spironitrogencyclyl” refers to the C5-C14/N1-N3-spironitrogencyclyl residues comprising or including the C5-C14-spiroheterocyclyl residues as disclosed above, wherein the heteroatom is nitrogen, i.e. Y is NH or NR11. The term “C5-C14/N1-N3” means that the spiro ring system consists of 5 to 14 carbon atoms and 1 to 3 nitrogen atoms. Moreover the spironitrogencyclyl residues can be substituted with 1 to 3 substituents selected from Z5, Z6 and Z7. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z5, Z6 or Z7. It is also possible that two of the substituents Z5, Z6 and Z7 represent together an oxygen atom and form together with the carbon atom of the spironitrogencyclyl residue to which they are both attached a carbonyl moiety. Moreover the C5-C14/N1-N3-spironitrogencyclyl residues are characterized in that the spironitrogencyclyl residue is linked through a nitrogen atom of the spiro ring system and not through a carbon atom of the spiro ring system. This means in regard to the above-mentioned C5-C14-spiroheterocycly residue that the heteroatom Y is nitrogen and that this C5-C14-spiroheterocycly residue is linked to the rest of the molecule through this nitrogen atom (which is Y). If the C5-C14/N1-N3-spironitrogencyclyl residue contains a second nitrogen atom which is substituted by one of the substituents Z5, Z6 and Z7, said Z substituent represents R12. Thus the indication “N2” refers to a first nitrogen atom through which the spironitrogencyclyl residue is linked and to the group




of the spiro ring system. If the spironitrogencyclyl residue contains a third nitrogen atom and both nitrogen atoms are substituted by one of the substituents Z5, Z6 and Z7, the first Z substituent on the second nitrogen atom represents R12 and the second Z substituent on the third nitrogen atom represents R11. Thus the indication “N3” refers to a first nitrogen atom through which the spironitrogencyclyl residue is linked and to the groups





of the spiro ring system. Thus the C5-C14/N1-N3-spironitrogencyclyl residue can contain one, two or three nitrogen atoms in the spiro ring system. The numbers of atoms “C5-C14/N1-N2” do not include C and N atoms from the substituents Z5 to Z7.

The term “C5-C14/N1-N3/O0-O2/S0-S1” means that the spiro ring system consists of 5 to 14 carbon atoms and 1 to 3 nitrogen atoms, 0 to 2 oxygen atoms and 0 or 1 sulfur atom. Moreover the nitrogenheterocyclyl residues can be substituted with 1 to 3 substituents selected from Z5, Z6 and Z7. However it is clear to a skilled person that the term “can be substituted” refers to the replacement of a hydrogen atom by one of the substituents Z5, Z6 or Z7. It is also possible that two of the substituents Z5, Z6 and Z7 represent together an oxygen atom and form together with the carbon atom of the nitrogenheterocyclyl residue to which they are both attached a carbonyl moiety. Moreover the C5-C14/N1-N3/O0-O2/S0-S1-nitrogenheterocyclyl residues are characterized by that the nitrogenheterocyclyl residue is linked through a nitrogen atom of the spiro ring system and not through a carbon atom of the spiro ring system. This means in regard to the above-mentioned C5-C14-spiroheterocycly residue that the heteroatom Y is nitrogen and that this C5-C14-spiroheterocycly residue is linked to the rest of the molecule through this nitrogen atom (which is Y). If the C5-C14/N1-N3/O0-O2/S0-S1-nitrogenheterocyclyl residue contains a second nitrogen atom which is substituted by one of the substituents Z5, Z6 and Z7, said Z substituent represents R12. Thus, the indication “N2” refers to a first nitrogen atom through which the nitrogenheterocyclyl residue is linked and to the group




of the spiro ring system. If the nitrogenheterocyclyl residue contains a third nitrogen atom and both nitrogen atoms are substituted by one of the substituents Z5, Z6 and Z7, the first Z substituent on the second nitrogen atom represents R12 and the second Z substituent on the third nitrogen atom represents R11. Thus, the indication “N3” refers to a first nitrogen atom through which the nitrogenheterocyclyl residue is linked and to the groups





and of the spiro ring system. The indication “S1” refers to the group —S— or —SO— or —SO2— of the spiro ring system. The indication “S0” means that no sulfur is present in the nitrogenheterocyclyl residue. The indication “O1” refers to the group —O— and the indication “O2” to two groups —O— which are not directly linked to each other, while “O0” indicates that no oxygen is present in the spiro ring system. Thus, the C5-C14/N1-N3/O0-O2/S0-S1-nitrogenheterocyclyl residue can contain in total 6 hetero atoms while in total not more than 3 hetero atoms should be present in the spiro ring system. Moreover it is preferred that the heteroatoms in the spiro ring system are not directly bond to each other. The numbers of atoms “C5-C4/N1-N3/O0-O2/S0-S1” do not include C, O, S and N atoms from the substituents Z5 to Z7.

SYNTHESIS OF COMPOUNDS
The inventive pyrazolo[1,5-a][1,3,5]triazines according to the present invention can be prepared by methods known to one skilled in the art. The synthesis is preferably carried out according to the general synthetic sequences, shown in schemes 3 and 4. This enables those skilled in the art to introduce to intermediate (IV) any suitable amine R2—NH2 that is commercially available or can be synthesized according to or in analogy to literature procedures. Further, after introduction of a methylsulfoxide leaving group by oxidation of the thioatom in (V) compounds with this formed methylsulfoxide group provides the basis to react with many classes of C-, S-, N- or O-nucleophiles that are available either commercially or by synthetic means. Therefore, the synthetic approach according to schemes 3 and 4 enables the synthesis of any of the pyrazolo[1,5-a][1,3,5]triazines disclosed in the present invention. However a person skilled in the art can also prepare these compounds following to other synthetic sequences.
In the following schemes occurring abbreviations mean DCM (dichloromethane); DIPEA (N-ethyl-N,N-diisopropylamine); DMF (dimethylformamide); DMSO (dimethyl sulfoxide); EtOAc (ethyl acetate); EtOH (ethanol); mCPBA (3-chlorobenzoperoxoic acid); MeOH (methanol); MeCN (acetonitrile); TFA (trifluoroacetic acid), PhNEt2 (dimethyl phenyl amine), Boc (tert-butyloxycarbonyl), Ph (phenyl), Ts (tosylate, p-toluenesulfonyl group), Mes (mesylate, methanesulfonyl group).




As depicted in scheme 1 in a first step 4-isopropyl-1H-pyrazol-5-amine was reacted with ethoxycarbonyl isothiocyanate to give a thiourea derivative that was cyclized to 2-mercaptopyrazolo[1,5-a][1,3,5]triazin-4-ol (11). The thiol (II) is then methylated by standard procedure to yield intermediate methylthioether (III).




Starting from (III) two further intermediate compounds can be derived as depicted in scheme 2. Firstly, after said methylation of the mercapto group in (II) 4-chloro-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazine (IV) was obtained by chlorination of (III) with phosphoryl trichloride in the presence of N,N-diethylaniline. Secondly, by oxidation of (III) the sulfone derivative (XVII) can be synthesized. Both, intermediate (IV) and (XVII) can be used for synthesis of the compounds of the present invention of the general formula (I) via various synthetic routes.




The residue A1 can be introduced by nuclephilic substitution reaction of (IV) with amines of the formula A1NH2, and DIPEA as a base yielding 4-amino-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazines (V) as shown in scheme 3, wherein A represents the upper benzyl building block of the compounds of the general formula (I)




wherein the R1, R3 to R7 represent the residues as defined herein.

Compounds (V) were then oxidized with 3-chlorobenzoperoxoic acid to 4-amino-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazines (VI) that could be substituted by reaction with compounds of the general formula R2—H yielding the compounds of the present invention of the general formula (I), wherein R2 and A1 represent residues as defined herein.




An alternative synthesis to the route outlined in scheme 3 is depicted in scheme 4 starting from intermediate (XVII). As one synthetic option the reaction of a nucleophile (R2—H) for introduction of the residue R2 takes place before the incorporation of the amine A1NH2 (upper pathway). In addition as a second synthetic option it is possible to obtain chloride (XX) and subsequently substitute said chloride before the sulfone is replaced by R2. The synthetic approach for the compounds of the general formula (I) according to scheme 4 has the advantage that the oxidation step for generating a sulfone from a thioether (here (III) converts to (XVII)) takes place before the introduction of the upper building block A1 by reaction with the amine A1NH2. Accordingly, moieties A1 being sensitive to oxidative reaction conditions can also be introduced, thereby broadening the scope of the compounds of the present invention significantly.
Conveniently, many substituted benzylamines A1NH2 as these are useful starting materials for the synthesis of the compounds of the general formula (I) are commercially available. Additional derivatives can be prepared by a person skilled in the art following known synthetic procedures that are disclosed in patent or non-patent literature. In principle, following any approach for the preparation of the compounds with the general formula A1-NH2 and thereby for the compounds of the present invention with the general formula (I) two aspects have to be considered. Firstly, the generation of the benzylic amino group in A1NH2 and secondly, the introduction of the desired substitution pattern as represented by R1 and R3-R7.
Journal and patent literature provide many examples for the synthesis of said alpha-alkylbenzylamines. Commonly used synthetic routes for such derivatives are outlined in scheme 5. Starting from a related imine it is possible to either alkylate with an alkyl metal species (like alkyl Grignard) or to reduce the imine double bond with hydrogen or a hydride source like NaBH4. Both reaction types may also be catalyzed and include stereoselective versions depending on the proper choice of a catalyst system or the N-substituent PG (protection group). In most cases it will be necessary to remove the N-linked moiety PG under appropriate conditions to obtain the desired alpha-alkylbenzylamines. Suitable protection groups are, for example, substituents such as alkyl sulfonyl e.g. tert.-butyl sulfonyl, alkyl silyl e.g. trimethyl silyl, alkyl, hydroxy, alcoholates, alkyl sulfinyl such as tert.-butyl sulfinyl and hydroyxalkyl such as 2-hydroxy-1-isopropylethyl.




wherein PG represents a suitable imine protection group such as alkyl sulfonyl e.g. tert.-butyl sulfonyl, alkyl silyl e.g. trimethyl silyl, alkyl, hydroxyl, alcoholates, alkyl sulfinyl such as tert.-butyl sulfinyl and hydroyxalkyl such as 2-hydroxy-1-isopropylethyl, and R1, R3 to R7 are as defined herein.

Depending on the target molecule with its specific substitution pattern (as represented by R3-R7) a person skilled in the art of organic chemistry will plan the synthetic approach for each benzylamine (XIII) individually and decide at which point the aminomethyl group and their related precursors will be synthesized.
According to the present invention alpha-substituent R1 in compounds of the general formula (I) is different from hydrogen, and preferably represents —CH3, which can easily be introduced by any amine of the formula A1-NH2. Further, as regards the substitution pattern at the phenyl group in the form of the substituents R3-R7, the skilled person will recognize that this can also be addressed readily by amines of the formula A1-NH2. Starting from a wide range of commercially available materials many synthetic approaches can therefore conveniently be applied to introduce these moieties at the respective position to yield compounds as defined in claim 1 and are well known to a person skilled in the art of synthesis. This can explicitly be performed by following any of the synthetic approaches as outlined above in schemes 3 and 4, where the moiety A1-NH2 can be conveniently introduced at different stages of the respective synthetic routes.
Further, there is also a huge number of reactions that enable a person skilled in the art of organic chemistry attaching R3, if chosen to be different from H or halide or sulfonate, in compounds of the general formula (I) via a carbon-carbon bond formation reaction. These reactions include but are not limited to catalyzed (e.g. by palladium, nickel, copper or iron species) cross-coupling reactions of an appropriate aryl halides or sulfonate (i.e. compounds of the general formula (I) with R3 being halide or sulfonate) with an alkyl, aryl or heteroaryl boron-, zinc-, magnesium-, tin- or silicon-reagent. Alternatively, for introduction of a broad range of substituents R3 it is possible to transform an aryl halide or sulfonate (e.g. triflate) into one of the above mentioned metal species that can be used in a cross-coupling reaction with for example alkyl, aryl or heteroaryl halide R3—X.
Further on scheme 3, synthetic options are presented for the rather general introduction of the residue R2 in the following schemes 6-8:




For example intermediate (VI) can be reacted with different nucleophiles to give derivatives (VII)-(IX) that all bear different residues A2 to A7 at the afore-mentioned R2 position in (I) in scheme 3.
In one embodiment in the synthesis of the compounds of the present invention amides of formula (XII) were synthesized via introduction of a cyanide group, transforming the resulting nitriles into imidoesters (XI) which underwent a subsequent nucleophilic attack with primary or secondary amines A3A4NH and hydrolysis to yield said related amides (scheme 7). In such embodiment the residue R2 is represented by the amide group —CO—NA3A4. For example, for A3 being R15 and A4 being R8 the case R2 being -Q-R8 with Q=—CO—NR15 is realized. Examples of the residue —CO—NA3A4 as represented by R2 are -Q-R8 with Q=—CO—, —CO—NH—(CH2)n—NH2, —CO—NH—(CH2)n—R9, —CO—NR10—(CH2)n—R9, —(CH2)a-(Q)b-(CH2)c-(G1)d-(CH2)e-(G2)f-(CH2)g—R8, —(CH2)a-(Q)b-(CH2)c-(G1)d-(CH2)e-(G2)f-CH2—R9 which can be synthesized according to the synthetic pathway as depicted in scheme 7.
Specifically, for R2=-Q-R8 and Q=—CO—NR15—, then A3=R15 and A4 represents R8. For R2=—CO—NH—(CH2)n—NH2, —CO—NH—(CH2)n—R9, A3=H and A4 represents (CH2)n—NH2, or (CH2)n—R9. For R2=—CO—NR1—(CH2)n—R9, A3=R10 and A4 represents (CH2)n—R9. For R2=—(CH2)a-(Q)b-(CH2)c-(G1)d-(CH2)e-(G2)f-(CH2)g—R8, a=0, b=1, and Q=—CO—NR15—, then A3=R15 and A4 represents (CH2)c-(G1)d-(CH2)e-(G2)f-(CH2)g—R8, wherein G1, G2, c, d, e, f, g, n, R8 and R9 are as defined herein.
For R2=—(CH2)a-(Q)b-(CH2)c-(G1)d-(CH2)e-(G2)f-CH2—R9, a=0, b=1, and Q=—CO—NR15—, then A3=R15 and A4 represents (CH2)c-(G1)d-(CH2)e-(G2)f-CH2—R9, wherein G1, G2, c, d, e, f, g, n, R8 and R9 are as defined herein.

As used herein, a kinase “inhibitor” refers to any compound capable of downregulating, decreasing, suppressing or otherwise regulating the amount and/or activity of a kinase. Inhibition of these kinases can be achieved by any of a variety of mechanisms known in the art, including, but not limited to binding directly to the kinase polypeptide, denaturing or otherwise inactivating the kinase, or inhibiting the expression of the gene (e.g., transcription to mRNA, translation to a nascent polypeptide, and/or final polypeptide modifications to a mature protein), which encodes the kinase. Generally, kinase inhibitors may be proteins, polypeptides, nucleic acids, small molecules, or other chemical moieties.
As used herein the term “inhibiting” or “inhibition” refers to the ability of a compound to downregulate, decrease, reduce, suppress, inactivate, or inhibit at least partially the activity of an enzyme, or the expression of an enzyme or protein and/or the virus replication.

Thus, another aspect of the present invention relates to drug combinations comprising at least one inventive compound according to general formula (I) and/or pharmaceutically acceptable salts thereof together with at least one anti-retroviral drug, especially at least one of the drugs mentioned above.
Thus, the compounds of the present invention are used for the manufacture of a pharmaceutical formulation for prophylaxis and/or treatment of infectious diseases, including opportunistic diseases, immunological diseases, autoimmune diseases, cardiovascular diseases, cell proliferative diseases, inflammation, erectile dysfunction and stroke.
The pharmaceutical compositions or formulations according to the present invention comprise at least one compound according to the present invention as an active ingredient together with at least one pharmaceutically acceptable (i.e. non-toxic) carrier, excipient and/or diluent. The pharmaceutical compositions of the present invention can be prepared in a conventional solid or liquid carrier or diluent and a conventional pharmaceutically-made adjuvant at suitable dosage level in a known way. The preferred preparations are adapted for oral application. These administration forms include, for example, pills, tablets, film tablets, coated tablets, capsules, powders and deposits.
Furthermore, the present invention also includes pharmaceutical preparations for parenteral application, including dermal, intradermal, intragastral, intracutan, intravasal, intravenous, intramuscular, intraperitoneal, intranasal, intravaginal, intrabuccal, percutan, rectal, subcutaneous, sublingual, topical, or transdermal application, which preparations in addition to typical vehicles and/or diluents contain at least one compound according to the present invention and/or a pharmaceutical acceptable salt thereof as active ingredient.
The pharmaceutical compositions according to the present invention containing at least one compound according to the present invention and/or a pharmaceutical acceptable salt thereof as active ingredient will typically be administered together with suitable carrier materials selected with respect to the intended form of administration, i.e. for oral administration in the form of tablets, capsules (either solid filled, semi-solid filled or liquid filled), powders for constitution, gels, elixirs, dispersable granules, syrups, suspensions, and the like, and consistent with conventional pharmaceutical practices. For example, for oral administration in the form of tablets or capsules, the active drug component may be combined with any oral non-toxic pharmaceutically acceptable carrier, preferably with an inert carrier like lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, talc, mannitol, ethyl alcohol (liquid filled capsules) and the like. Moreover, suitable binders, lubricants, disintegrating agents and coloring agents may also be incorporated into the tablet or capsule. Powders and tablets may contain about 5 to about 95-weight % of the pyrazolo[1,5-a][1,3,5]triazine derivatives according to the general formula (I) or analogues compound thereof or the respective pharmaceutically active salt as active ingredient.
Suitable binders include starch, gelatin, natural sugars, corn sweeteners, natural and synthetic gums such as acacia, sodium alginate, carboxymethylcellulose, polyethylene glycol and waxes. Among suitable lubricants there may be mentioned boric acid, sodium benzoate, sodium acetate, sodium chloride, and the like. Suitable disintegrants include starch, methylcellulose, guar gum, and the like. Sweetening and flavoring agents as well as preservatives may also be included, where appropriate. The disintegrants, diluents, lubricants, binders etc. are discussed in more detail below.
Moreover, the pharmaceutical compositions of the present invention may be formulated in sustained release form to provide the rate controlled release of any one or more of the components or active ingredients to optimise the therapeutic effect(s), e.g. antihistaminic activity and the like. Suitable dosage forms for sustained release include tablets having layers of varying disintegration rates or controlled release polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices.
Liquid form preparations include solutions, suspensions, and emulsions. As an example, there may be mentioned water or water/propylene glycol solutions for parenteral injections or addition of sweeteners and opacifiers for oral solutions, suspensions, and emulsions. Liquid form preparations may also include solutions for intranasal administration.
Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be present in combination with a pharmaceutically acceptable carrier such as an inert, compressed gas, e.g. nitrogen.
For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides like cocoa butter is melted first, and the active ingredient is then dispersed homogeneously therein e.g. by stirring. The molten, homogeneous mixture is then poured into conveniently sized moulds, allowed to cool, and thereby solidified. Also included are solid form preparations, which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions, and emulsions.
The compounds according to the present invention may also be delivered transdermally. The transdermal compositions may have the form of a cream, a lotion, an aerosol and/or an emulsion and may be included in a transdermal patch of the matrix or reservoir type as is known in the art for this purpose.
The term capsule as recited herein refers to a specific container or enclosure made e.g. of methylcellulose, polyvinyl alcohols, or denatured gelatins or starch for holding or containing compositions comprising the active ingredient(s). Capsules with hard shells are typically made of blended of relatively high gel strength gelatins from bones or pork skin. The capsule itself may contain small amounts of dyes, opaquing agents, plasticisers and/or preservatives.
Under tablet a compressed or moulded solid dosage form is understood which comprises the active ingredients with suitable diluents. The tablet may be prepared by compression of mixtures or granulations obtained by wet granulation, dry granulation, or by compaction well known to a person of ordinary skill in the art.
Oral gels refer to the active ingredients dispersed or solubilised in a hydrophilic semi-solid matrix.
Powders for constitution refers to powder blends containing the active ingredients and suitable diluents which can be suspended e.g. in water or in juice.
Suitable diluents are substances that usually make up the major portion of the composition or dosage form. Suitable diluents include sugars such as lactose, sucrose, mannitol, and sorbitol, starches derived from wheat, corn rice, and potato, and celluloses such as microcrystalline cellulose. The amount of diluent in the composition can range from about 5 to about 95% by weight of the total composition, preferably from about 25 to about 75 weight %, and more preferably from about 30 to about 60 weight %.
The term disintegrants refers to materials added to the composition to support break apart (disintegrate) and release the pharmaceutically active ingredients of a medicament. Suitable disintegrants include starches, “cold water soluble” modified starches such as sodium carboxymethyl starch, natural and synthetic gums such as locust bean, karaya, guar, tragacanth and agar, cellulose derivatives such as methylcellulose and sodium carboxymethylcellulose, microcrystalline celluloses, and cross-linked microcrystalline celluloses such as sodium croscaramellose, alginates such as alginic acid and sodium alginate, clays such as bentonites, and effervescent mixtures. The amount of disintegrant in the composition may range from about 2 to about 20 weight % of the composition, more preferably from about 5 to ca. 10 weight %.
Binders are substances which bind or “glue” together powder particles and make them cohesive by forming granules, thus serving as the “adhesive” in the formulation. Binders add cohesive strength already available in the diluent or bulking agent. Suitable binders include sugars such as sucrose, starches derived from wheat corn rice and potato, natural gums such as acacia, gelatin and tragacanth, derivatives of seaweed such as alginic acid, sodium alginate and ammonium calcium alginate, cellulose materials such as methylcellulose, sodium carboxymethylcellulose and hydroxypropylmethylcellulose, polyvinylpyrrolidone, and inorganic compounds such as magnesium aluminum silicate. The amount of binder in the composition may range from about 2 to about 20 weight % of the composition, preferably from about 3 to about weight %, and more preferably from about 3 to about 6 weight %.
Lubricants refer to a class of substances which are added to the dosage form to enable the tablet granules etc. after being compressed to release from the mould or die by reducing friction or wear. Suitable lubricants include metallic stearates such as magnesium stearate, calcium stearate, or potassium stearate, stearic acid, high melting point waxes, and other water soluble lubricants such as sodium chloride, sodium benzoate, sodium acetate, sodium oleate, polyethylene glycols and D,L-leucine.
Lubricants are usually added at the very last step before compression, since they must be present at the surface of the granules. The amount of lubricant in the composition may range from about 0.2 to about 5 weight % of the composition, preferably from about 0.5 to about 2 weight %, and more preferably from about 0.3 to about 1.5 weight % of the composition.
Glidents are materials that prevent caking of the components of the pharmaceutical composition and improve the flow characteristics of granulate so that flow is smooth and uniform. Suitable glidents include silicon dioxide and talc. The amount of glident in the composition may range from about 0.1 to about 5 weight % of the final composition, preferably from about 0.5 to about 2 weight %.
Coloring agents are excipients that provide coloration to the composition or the dosage form. Such excipients can include food grade dyes adsorbed onto a suitable adsorbent such as clay or aluminum oxide. The amount of the coloring agent may vary from about 0.1 to about 5 weight % of the composition, preferably from about 0.1 to about 1 weight %.

Compound (VIII-d)
(S)-8-isopropyl-N4-(1-phenylethyl)-N2-(piperidin-4-mia




20 mg (0.056 mmol) methylsulfone (VI-a) were added to a solution of tert-butyl 4-aminopiperidine-1-carboxylate (34 mg, 0.167 mmol) in 1 ml NMP and stirred 18 h at 120° C. The Boc-protected intermediate was obtained after purifying using silica gel and eluting with a cyclohexane/ethyl acetate gradient. The remaining Boc-protecting group was removed in TFA and the pure compound (VIII-a) was obtained after RP-HPLC using a water/acetonitrile (0.1% TFA) gradient.

Boc-protected (VII-bp) was obtained as described in method C but without the deprotection step. 10.9 mg (0.021 mmol) thioether were oxidized in 1 ml DCM at 0° C. using 2.9 mg (0.017 mmol) mCPBA. After 1 h the reaction mixture was diluted with ethyl acetate and washed with 2 M NaOH solution and brine. The organic phase was dried over MgSO4, concentrated under reduced pressure and purified on silica gel using an ethyl acetate/cyclohexane gradient. The resulting intermediate was dissolved in 20% TFA/DCM. After the Boc-group was cleaved the title compound was obtained after RP-HPLC using a water/acetonitrile (0.1% TFA) gradient.

After 24 h the mixture was purified on silica gel eluting with a cyclohexane/ethyl acetate gradient. The resulting intermediate was dissolved in methanol and stirred with 20 mg K2CO3 at 40° C. for 1 h. The mixture was filtered, and the solvent was removed under reduced pressure. After TFA cleavage of the Boc-protecting group, the crude product was purified by RP-HPLC using a water/acetonitrile (0.1% TFA) gradient.
Results:
1. Measurement of Binding Affinities to CDKs
This protocol describes how the Lance Kinase Activity Assay was performed to determine IC50 values of compounds of general formula (I) against CDK/Cyclin complexes. The principle behind this enzymatic assay is based upon the phosphorylation of the Ulight-Peptide Substrat. It is detected by using a specific EU-labeled anti-phospho peptide antibody. The binding of the Eu labeled anti-phospho peptide antibody to the phosphorylated ULight (trade mark) labeled peptide gives rise to a FRET-signal.
Binding of an inhibitor to the kinase prevents phosphorylation of the ULlight-MBP Substrat, resulting in a loss of FRET.

The compounds of general formula (I) exemplary summarized in Table 1 were diluted from a 10 mM DMSO stock solution 1:10 in a total volume of 15 μl DMSO. This compound predilution was then serial diluted 1:3 over 8 steps in DMSO and briefly spun down. Each compound solution was now diluted 1:20 in Enzymatic Buffer (HEPES: 50 mM, pH: 7.5; MgCl2: 10 mM; EGTA: 1 mM; DTT: 2 mM; Tween-20: 0.01%), mixed thoroughly and spun down.
For every sample, 2 μl of the diluted compound were mixed with 6 μl CDK2/CycA/substrate working solution (8.33 nM CDK2/CycA; 83.33 nM ULight MBP substrate in enzymatic buffer) and 2 μl ATP working solution (15 μM ATP in enzymatic buffer) in a well of a small volume 384 well plate (Corning Incorporated, Corning, N.Y., USA; order no. 3673). For negative controls, in each well 2 μl of DMSO working solution (5% DMSO diluted in enzymatic buffer) was mixed with 6 μl substrate working solution (83.33 nM ULightMBP substrate in enzymatic buffer) and 2 μl ATP working solution. For positive controls, 2 μl of DMSO working solution were mixed with 6 μl CDK2/CycA/substrate working solution and 2 μl ATP working solution. Positive and negative controls were calculated from at least 8 different wells. The 384 well plates were mixed in a Teleshaker plate mixer (Beckman Coulter, Brea, Calif., USA) at 2000 rpm for 40 sec, and incubated for 1 h at room temperature before addition of 10 μl LANCE Detection Buffer (EDTA: 20 nM; Eu-Anti-P-MBP: 4 nM) per well. Plates were mixed in a Teleshaker plate mixer (Beckman Coulter, Brea, Calif., USA) at 2000 rpm for sec, followed by incubation with Detection Buffer for 1 h, and reading. The FRET signal was measured at 340 nm excitation, 665 nm and 615 nm emission (for the ULight MBP substrate and LanthaScreen Eu-AB, respectively) with an Envision spectrophotometer (Perkin Elmer, Waltham, Mass., USA) with 90 μs delay and 20 μs integration time. IC50 values were determined from the sigmoidal dose response curves with the software Quattro Workflow (Quattro GmbH, Munich, Germany). In case of tight binding of the inhibitors to CDK2/CycA, final assay concentrations were adjusted to 0.25 nM Eu-Anti-MBP AB, 2 nM CDK2/CycA and 30 μM ATP, and IC50 values were converted according to the Cheng Prusoff equation to the IC50 values at the original ATP-concentration.

Comparative Examples
In order to show the surprising effects of the compounds of the present invention the Comparative Examples C-I, C-III and C-III, wherein according to the compounds of the general formula (I) R1=H, have been tested in the enzymatic activity assays for CDK2, CDK7 and CDK9 as described above. C-I and C-II have the following structural formulae:




The selectivity results of Comparable Examples C-1 and C-II are directly comparable to the compounds of the present invention as summarized in Table 5. While all compounds show potency against scree CDK-7, only the compounds of the present invention do not significantly inhibit also CDK-2 and CDK-9. Therefore, the compounds of the present invention can selectively inhibit CDK-7. The degree of selectivity is demonstrated in Table 6 by the multiplicity of the CDK2 and CDK9 activity in terms of the CDK7 activity. For example, while C-1 only shows merely the same activity for all three CDK 2, CDK 7 and CDK 9 indicating that C-1 inhibits all three CDK inhibitors simultaneously, the exemplary compound of the present invention (VII-j) selectively inhibits only CDK7 while the activities for CDK2 and CDK 9 are tremendously higher (up to over the 733-fold activity of the CDK7 activity).
Also, members of the CDK family have been validated as targets in cancer and inflammatory disease as well as in HIV-1 treatment. However, first generation CDK-inhibitors (Flavopiridol, Roscovitine, SNS-032) do typically inhibit more than one member of the CDK family. Such non specific-CDK inhibitors are meanwhile known for their toxicities and small therapeutic windows in clinical trials. Indeed, knockdown of multiple CDKs is lethal in a variety of model organisms, whereas knockdown of single CDKs is frequently tolerated; indicating that inhibition of single CDKs is less toxic. Therefore, the main goal in the field of CDK-inhibition is the optimization for selective small-molecule based CDK-inhibitors.
As becomes apparent from Table 7 below first generation CDK-inhibitors generally do not show satisfactory CDK7 inhibition in comparison to the compounds of the present invention, nor do they show any significant effect that CDK 2 or CDK 9 are not inhibited simultaneously. This could at best be addressed for BS-181, however the comparative CDK 7 inhibition is poor and the CDK 2 and CDK 9 inhibition is far below a hundred-fold activity of the CDK 7 activity. In case of SNS-032 and Flavopiridol the CDK 2 and CDK 9 activities are even lower than the CDK 7 activity.
