HYDROXAMATE DERIVATIVES SUITABLE AS DEACETYLASE INHIBITORS

FIELD: synthesis of biologically active compounds. ^ SUBSTANCE: invention relates to hydroxamate derivatives described by general formula I: , in which R1 represents H or linear C1-C6-alkyl; R2 hydrogen, 1-10-alkyl optionally substituted by 1-5 constituents selected from hydroxy, amino, hydroxyalkyl; C4-C9-cycloalkyl; aryl; C4-C9-heterocycloalkyl, C4-C9-heterocycloalkylalkyl containing 2 heteroatoms (nitrogen and/or oxygen); C4-C9-cycloalkylalkyl; arylalkyl; heteroarylalkyl containing 1-4 nitrogen atoms as heteroatoms; -(CH2)nC(O)R6, -(CH2)nOC(O)R6, -N(R12)C(O)-W; HONH-C(O)-CH=C(R1)arylalkyl, and (CH2)nR7; R3 and R4, identical or different, independently denote hydrogen, optionally OH-substituted C1-C6-alkyl; C(O)-O-W, or -N(R12)C(O)W; or R3 and R4 together with carbon atom, to which they are linked, represent C=O; or R2 together with carbon atom, to which it is linked, and R3 together with carbon atom, to which it is linked, can form C4-C9-heterocycloalkyl containing 2 nitrogen atoms as heteroatoms; or mixed aryl or non-aryl polyheterocyclic ring; R5 is selected from hydrogen; C1-C6-alkyl; C4-C9-cycloalkyl; C(O)-W; aryl optionally substituted by 1-2 constituents selected from halogen and hydroxyalkyl; heteroaryl containing nitrogen as heteroatom; arylalkyl; aromatic polycycle; polyheteroaryl containing 1-2 nitrogen atoms as heteroatoms and optionally substituted by 1-2 substituents selected from hydroxyalkyl, halogen, alkyl, and aryl; mixed aryl-nonaryl polyheterocycle containing nitrogen or oxygen atom as heteroatom and optionally substituted by groups -N-OH, =N-OH; n, n1, n2, and n3, identical or different, are independently selected from within a range of 0-6; X and Y, identical or different, are independently selected from hydrogen, halogen, and nitro group; or pharmaceutically acceptable salt thereof. Invention also relates to a pharmaceutical composition showing inhibitory activity toward hydroxamate derivative of general formula I in combination with one or several pharmaceutically acceptable carriers. Hydroxamate derivative of general formula I are also appropriate for treating proliferative disease and regulating p21 promoter. ^ EFFECT: enabled use of hydroxamate derivatives as deacetylase inhibitors. ^ 42 cl, 6 tbl, 272 ex
