FIELD: organic chemistry, medicine, pharmacy. ^ SUBSTANCE: invention relates to novel compounds of the formula (IA) or (IB) given in the invention description wherein R1 means hydrogen atom, (C1-C7)-alkyl, -(CH2)n-OH, -(CH2)n-N(R6)2; R2 means (C1-C7)-alkyl, -(CH2)n-N(R6)2, -NR6C(O)C(O)O-(C1-C7)-alkyl, -NR6-(CH2)n-OH, -NR6C(O)-(C1-C7)-alkyl, -NH-benzyl; R3 means hydrogen atom or amine; or R2 and R3 in common with carbon atoms to which they are bound mean the group -N(R6)-CH2-O-CH2-; R4 means hydrogen atom or (C1-C7)-alkyl; R5 means hydrogen atom; R6 means independently of one another hydrogen atom or (C1-C7)-alkyl; R' means hydrogen atom or (C1-C7)-alkyl; n = 0, 1, 2 or 3. Also, invention relates to a medicinal agent possessing the selective blocking activity with respect of subspecies of NMDA-receptors and containing one or more compounds of the formula (IA) or (IB) or their pharmaceutically acceptable acid-additive salt or inert carrier. Invention provides preparing novel compounds possessing the high affinity to NMDA-receptors that can be used as components of a medicinal agent for treatment of diseases mediated by these receptors. ^ EFFECT: valuable medicinal properties of compounds and drug. ^ 13 cl, 35 ex |
