FIELD: chemistry. n SUBSTANCE: invention relates to a method of modulating expression of a target gene induced by β-catenin using an agent which increases linkage of p300 with β-catenin and reduces linkage of CBP with β-catenin, involving bringing a composition containing β-catenin, CBP and p300, where β-catenin is more likely linked to CBP than p300, into contact with an agent in an amount which is effective for changing the probability of linking β-catenin to CBP compared to p300, where the said agent is a compound with a structure selected from formula (I), or its stereoisomers: where A represents -(C=O)-, B represents -(CHR 4 )-, D represents -(C=O)-, E represents -(ZR 6 )-, G represents -(XR 7 ) n -> W represents (C=O)NH-, X represents nitrogen or CH, Z represents CH, n = 0 or 1. Values of substitutes R 1 and R 2 are indicated in the formula of invention. The invention also relates to a composition for modulating expression of a target gene induced by β-catenin. n EFFECT: novel compounds have useful biological properties. n 9 cl, 7 tbl, 30 dwg, 7 ex |
