Molecular design of multitarget neuroprotectors 2. Synthesis and bioactivity of carbazole—γ-carboline conjugates

Abstract

Earlier unknown conjugates of carbazoles and γ-carbolines were obtained by the reaction of 3,6-substituted 9-oxiranylmethylcarbazoles and 2,8-substituted 2,3,4,5-tetrahydro-1H-pyrido-[4,3]indoles. The effects of synthesized 1-(9H-carbazol-9-yl)-3-(1,2,3,4-tetrahydro-5H-pyrido-[4,3-b]indol-5-yl)propan-2-ones and their hydrochlorides on neuronal NMDA receptors, polymerization of tubulin to form microtubules, and functional characteristics of rat liver mitochondria were studied.
