(C1-C6)-alkylcarbonyl, di-[C1-C8)-alkyl]-aminoalkoxycarbonyl, di-[(C1-C8)-alkyl]-amino-(C1-C8)-alkylaminocarbonyl; a = a whole number from 0 to 1; Y is taken among the group consisting of -CH2, -C(O); Z is taken among the group consisting of -CH2, -CHOH, and -C(O) under condition that when Z represents -CHOH or -C(O) then X represents -NH; is taken among the group consisting of naphthyl, 5-6-membered heteroaryl comprising 1-3 heteroatoms taken among nitrogen, oxygen and/or sulfur atoms possibly condensed with benzene ring; m = a whole number from 0 to 2; R3 is taken independently among the group consisting of halogen atom, nitro-group, (C1-C8)-alkyl, (C1-C8)-alkoxy-group, trifluorophenyl, phenyl (optionally substituted with 1-3 RB), phenylsulfonyl, naphthyl, (C1-C8)-aralkyl, 5-6-membered heteroaryl comprising 1-3 nitrogen atoms in the ring (optionally substituted with 1-3 RB). Also, invention relates to a pharmaceutical composition, a method for its preparing and methods for inhibition of phosphodiesterase V activity (PDE V), and for increase of the cGMP concentration.

EFFECT: improved preparing method, valuable medicinal and biochemical properties of compounds and composition.

FIELD: chemistry.

SUBSTANCE: claimed are novel pyrazole derivatives of formula II or its pharmaceutically acceptable salts, where C ring is selected from phenyl or pyridinyl ring and R2, R2', Rx and Ry are such as said in given description. C ring has ortho-substituent and is optionally substituted in non-ortho positions. R2 and R2' , optionally taken with their intermediate atoms, form condensed ring system, such s indazole ring, and Rx and Ry, optionally taken together with their intermediate atoms, form condensed ring system, such a quinazoline ring.

EFFECT: possibility to use compositions as inhibitors of protein kinases as inhibitors GSK-3 and other kinases and apply them for protein kinase-mediated diseases.
