DERIVATIVES OF 5-(2H-PYRROLE-2-YLIDENE)METHYL-2,2'-BI-1H- -PYRROLE SHOWING IMMUNOMODULATING ACTIVITY, METHOD OF THEIR SYNTHESIS, PHARMACEUTICAL COMPOSITION BASED ON THEREOF

摘要

FIELD: organic chemistry, pharmacy. SUBSTANCE: invention proposes derivatives of 5-[(2H-pyrrole-2-ylidene)methyl] -2,2'-bi-1H- -pyrrole of the general formula (I) where R means H or C₁-C₆-alkyl; R₂,R₄,R₅ mean hydrogen atom; R₃ means C₁-C₅-alkoxy-group that can be free or substituted with phenyl; R₆ means hydrogen atom, C₃-C₁₄-alkenyl or C₁-C₂₀-alkyl that can be free or substituted with halogen atom, hydroxy-group, phenyl, phenylhydroxy-, carboxy-, cyano- or -CO-morpholino-group; or R₅ and R₆ in common form C₄-C₉-polymethylene chain that can be substituted with C₁-C₁₂-alkyl; and their pharmaceutically acceptable salts showing immunomodulating activity. Invention proposes the method of synthesis of compounds of the formula (I) by interaction of the compound of the formula (II) with the compound of the formula (III) also and the pharmaceutical composition showing immunomodulating activity. EFFECT: improved method of synthesis, valuable immunological properties. 12 cl, 10 ex
