FIELD: chemistry; medicine. ^ SUBSTANCE: compounds of claimed invention possess properties of positive allosteric modulator mGluR5. In general formula I , W represents 6-member heterocycloalkyl ring with 1-2 heteroatoms, selected from N, O; R1 and R2 independently represent hydrogen, C1-C6-alkyl; P and Q each independently is selected from: , R3, R4, R5, R6 and R7 independently represent hydrogen; halogen; -CN; nitro; C1-C6-alkyl; C3-C6-cycloalkyl; halogen-C1-C6-alkyl; 5-6-member heteroaryl with 1-2 atoms N as heteroatoms; 6-member heterocycle with 2 heteroatoms representing N, O; phenyl, optionally substituted with halogen; naphtyl; -OR8; where optionally two substituents together with located between them atoms form 9-10-member bicyclic aryl or heteroaryl ring with 1-2 heteroatoms, selected from N, S; R8 represents hydrogen, C1-C6-alkyl; D, E, F, G and H independently represent -C(R3)=, -O-, -N=, -N(R3)- or -S-; A represents ethinyl, -C(=O)NR8- or group of formula . B represents -C(=O)-C0-C2-alkyl-, -C(=O)-C2-C6-alkenyl-. Invention also relates to pharmaceutical composition based on invention compounds. ^ EFFECT: novel compounds possess useful biological proprties. ^ 20 cl, 3 dwg, 75 ex |
