FIELD: medicine, pharmaceutics.
SUBSTANCE: invention relates to compound of formula: 
or to its pharmaceutically acceptable salt, where: Ar2 represents phenyl or pyridyl, each of which is substituted by 0-4 substituents, independently selected from R2; X and Z represent N; Y represents CRX; D represents N; F represents N, CH or carbon, substituted by substituent, representing R1 or R10; Rx in each case is independently selected from hydrogen, halogen, C1-C4alkyl, amino, cyano and mono- or di-(C1-C4alkyl)amino; R1 represents 0-3 substituents, independently selected from: (a) halogen, cyano and nitro; (b) groups of formula -Q-M-Ry; R10 represents one substituent, selected from: (a) groups of formula -Q-M-Ry; so that R10 is not hydroxy, amino or unsubstituted group, selected from C1-C6alkyl, C2-C6alkenyl, C2-C6alkinyl, C1-C6aloxy, C2-C6alkyl, ether, C2-C6alkanoyl, C3-C6alcanone, C1-C6halogenalkyl, C1-C6halogenoalkoxy, mono- or di-(C1-C6alkyl)amino, C1-C6alkylsulfonyl, mono- or di-(C1-C6alkyl)aminosulfonyl or mono- or di-(C1-C6alkyl)aminocarbonyl; each Q is independently selected from C0-C4alkylene; each M is independently absent or is selected from O, C(=O), OC(=O), C(=O)O, S(O)m, N(RZ), C(=O)N(Rz), C(=NH)N(Rz), N(Rz)C(=O), N(Rz)C(=NH), N(Rz)S(O)m, S(O)mN(Rz) and N[S(O)mRz]S(O)m, where m equals 2; and Rz in each case is independently selected from hydrogen, C1-C8alkyl and groups, which taken together with Ry, form possibly substituted (4-7)-member heterocycle; and each Ry independently represents hydrogen, C1-C8halogenalkyl, C1-C8alkyl, C2-C8alkenyl, (C3-C8carbocycle)C0-C4alkyl, ((4-7)-member heterocycle)C0-C4alkyl or taken together with Rz forms (4-7) member heterocycle, where each alkyl, carbocycle and heterocycle is substituted by 0-4 substituents, independently selected from hydroxy, halogen, amino, cyano, nitro, -COOH, aminocarbonyl, aminosulfonyl, C1-C6alkyl, C3-C7cecloalkyl, C2-C6alkyl ether, C1-C6alkanoyl, C1-C6alkylsulfonyl, C1-C8alkoxy, C1-C8hydroxyalkyl, mono- and di-(C1-C6alkyl)aminocarbonyl, mono- and di-(C1-C6alkyl)aminosulfonyl, mono- and di-(C1-C6alkyl)amino, C1-C6alkanoylamino and phenyl; so that Ry is not hydrogen, if Q represents C0alkyl and M is absent; each R2: (a) is independently selected from (1) hydroxyl, amino, cyano, halogen, -COOH, nitro and (2) C1-C6alkyl, (C3-C8cycloalkyl)C0-C4alkyl, C1-C6halogenalkyl; R3 is selected from: (1) hydrogen; (2) C1-C6alkyl and (C3-C8cycloalkyl)C0-C2alkyl; and (3) groups of formula: 
where L represents C0-C6alkylene; R5 and R6: (a) are independently selected from C1-C12alkyl, (C3-C8cycloalkyl)C0-C4alkyl; or (b) are combined with formation of (4-6)-member heterocycle, containing one or two heteroatoms independently selected from O and N; and where each of (2) and (3) is substituted by 0-4 substituents, independently selected from: C1-C6alkyl and (C3-C8cycloalkyl)C0-C2alkyl, each of which is substituted by 0-4 secondary substituents, independently selected from hydroxy, C1-C4alkyl and C1-C4alkoxy; and R4 represents 0-2 substituents, independently selected from C1-C3alkyl.
EFFECT: claimed are pharmaceutical compositions for modulation of capsaicin receptor activity and methods of applying said compounds for treatment of such disorders as pain, itch, cough, hiccup, urinary incontinence or obesity.
