SUBSTANCE: invention proposes compound of the formula (I): 
wherein cycle A represents imidazo[1,2-a]pyrid-3-yl or pyrazole[2,3-a]pyrid-3-yl; R2 is joined to cyclic carbon atom and taken among halogen atom, cyano-group, (C1-C6)-alkyl, (C1-C6)-alkoxy-group, (C1-C6)-alkyl-S(O)a wherein a = 0, phenyl, phenylthio- or (heterocyclic group)-thio-group wherein any (C1-C6)-alkyl, phenyl or heterocyclic group can be substituted optionally by carbon atom with one or some G wherein heterocyclic group represents saturated, partially saturate or unsaturated, mono- or bicyclic structure comprising 4-12 atoms among them at least atom is taken among nitrogen, sulfur or oxygen atom that can be bound if another variants are not specified with unsaturated, mono- or bicyclic structure comprising 4-12 atoms among them at least one atom is taken among nitrogen, sulfur or oxygen atoms that can be bound if another variants are not specified with carbon or nitrogen atom wherein group -CH2- can be substituted optionally with -C(O)- and cyclic atom can carry optionally (C1-C6)-alkyl group and to form quaternary compound, or cyclic atom of nitrogen and/or sulfur can be oxidized to form N-oxide and/or S-oxides; m = 0-2 and R2 values can be similar or different; R1 means halogen atom, (C1-C3)-alkyl-S(O)a wherein a = 0 wherein any (C1-C3)-alkyl can be substituted optionally by carbon atom with one or some J; n = 0-1; cycle B represents phenyl or phenyl condensed with (C5-C7)-cycloalkyl cycle; R3 means halogen atom or sulfamoyl; p = 0-2 and R3 values can be similar or different; R4 means group A-E- wherein A is taken among (C1-C6)-alkyl, phenyl, heterocyclic group, (C3-C8)-cycloalkyl, phenyl-(C1-C6)-alkyl, (heterocyclic group)-(C1-C6)-alkyl or (C3-C8)-cycloalkyl-(C1-C6)-alkyl wherein (C1-C6)-alkyl, phenyl, heterocyclic group, (C3-C8)-cycloalkyl, phenyl-(C1-C6)-alkyl, (heteroccyclic group)-(C1-C6)-alkyl or (C3-C8)-cycloalkyl-(C1-C6)-alkyl can be substituted optionally by carbon atom with one or some D and wherein above mentioned heterocyclic group comprises fragment -NH- then nitrogen atom can be substituted optionally with group taken among R; E means a simple bond or -O-, -C(O)-, -N(Ra)C(O)- or -N(Ra)SO2-, -S(O)r wherein Ra means hydrogen atom or (C1-C6)-alkyl and r = 0-2; D is taken independently among hydroxy-, amino- (C1-C6)-alkoxy-, N-(C1-C6-alkyl)-amino-, N,N-(C1-C6-alkyl)-amino-, (C1-C6)-alkoxycarbonylamino- and benzyloxycarbonylamino-group wherein any (C1-C6)-alkyl or phenyl can be substituted optionally by carbon atom with one or some K; q = 0-1; G, J and K are taken independently among hydroxy-, dimethylamino-, diethylamino-group; R is taken among (C1-C4)-alkyl; or its pharmaceutically acceptable salt. Invention proposes applying pyrimidine compounds for inhibition of activity of kinases CDK2, CDK4 and CDK6 in cellular cycle eliciting anti-proliferative properties. Indicated properties have value in treatment of cancer diseases (solid tumors and leukemia), fibroproliferative and differential disorders, psoriasis, rheumatoid arthritis, Kaposi's sarcoma, hemangioma, acute and chronic nephropathy, atheroma, atherosclerosis, arterial repeated stenosis, osseous and ophthalmic diseases with proliferation of cellular tissue in vessels.
EFFECT: valuable medicinal properties of compounds.
