ESTER DERIVATIVE OF 2-AMINO-BICYCLO[3,1,0]HEXANE-2,6-DICARBOXYLIC ACID, WITH ANTAGONISTIC PROPERTIES TOWARDS P-GROUP METABOTROPIC GLUTAMATE RECEPTORS

FIELD: chemistry. ^ SUBSTANCE: present invention pertains to new ester derivatives of 2-amino-bicyclo[3,1,0]hexane-2,6-dicarboxylic acid, with formula [I] or [II] and their pharmaceutical salts, with antagonistic properties towards II group metabotropic glutamate receptors. In general formulae [I] or [II] R1 and R2 are identical or different, and each stands for a C1-10alkyl group, or one of R1 or R2 is a hydrogen atom, and the other is a C1-10alkyl group, C2-10alkenyl group, C2-10alkynyl group, C1-10alkyl group, substituted with a phenyl group, possibly substituted with halogen atoms, C1-4alkyl group, C1-4 alkoxyl group; hydroxyC2-10alkyl group, halogenC1-10alkyl group, azidoC1-10alkyl, aminoC2-10alkyl, C1-10alkoxycarbonylC1-10alkyl group, farnesyl group, 4-morpholinyl-C1-10alkyl group, C1-10alkyl group, substituted with a group with formula -C(O)NRaRb (where Ra and Rb are identical or different and each represents a hydrogen atom or a C1-10alkyl group), or with a group with formula -CHRcOC(O)ZRd (where Z is an oxygen atom or a single bond; Rc represents a hydrogen atom, C1-10alkyl group or aryl group, chosen from phenyl and naphthyl, which can be substituted with a C1-4alkyl group or C1-4alkoxyl group), or substituted with a group with formula [i] [ii], (where Rd denotes the same as described above), or by a group with formula [ii]; X is a fluorine atom; and Y represents -OCHR3R4, -SR3, -S(O)nR5, -SCHR3R4, -NHCHR3R4, -N(CHR3R4)(CHR3'R4'), -NHCOR3 or -OCOR5 (where R3, R3', R4 and R4' are identical or different, and each represents a hydrogen atom, C1-10alkyl group, phenyl group, naphthyl group, phenyl group substituted with one-five substitutes, chosen from a group, consisting of a halogen atom, R5 represents a phenyl group, or a phenyl group substituted with one-five substitutes, chosen from a group, consisting of a halogen atom, and n is 1 or 2). ^ EFFECT: invented compounds can be used in treating and preventing mental illnesses, such as schizophrenia, anxiety and anxiety related diseases, depression, bipolar disorders and epilepsy, invention also pertains to a medicinal preparation. ^ 30 cl, 5 tbl, 19 ex
