FIELD: chemistry. ^ SUBSTANCE: in compounds of formula: ^ , A and B denote a pair of condensed saturated or unsaturated 5- or 6-member rings, where the said system of condensed rings A/B contains 0-2 nitrogen atoms, and said rings are further substituted with 0-4 substitutes independently selected from halogen, lower alkyl or oxo; and a and b are bonding positions for residues Y and D, respectively, and these positions a and b are in the peri-position relative each other on the said condensed ring system A/B; d and e are condensed positions between ring A and ring B in the said condensed ring system A/B; D is an aryl or heteroaryl cyclic system which denotes a 5- or 6-member aromatic ring containing 0-3 heteroatoms selected from O, N or S; which can be further substituted with 0-4 substitutes independently selected from lower alkyl and amine; Y is selected from -CH2 and -O-; M is selected from aryl, aryl substituted with a halogen or alkoxy; R1 is selected from aryl, aryl substituted with a halogen, heteroaryl, heteroaryl substituted with a halogen, where heteraryl denotes a 5- or 6-member aromatic ring containing 0-3 heteroatoms selected from O, N or S, and CF3; and if Y denotes -CH2- or -O-, then R1 further denotes a lower alkyl. The invention also pertains to use of compounds in claim 1, a pharmaceutical composition, a screening method on selective ligands of prostanoid receptors, as well as compounds of the formula. ^ EFFECT: obtaining novel biologically active compounds for inhibiting binding of prostanoid E2 with EP3 receptor. ^ 25 cl, 46 ex |
