The synthesis and the study of the activity of new indol-2-carboxamides and pyridazino[4,5-b]indoles as inhibitors of HIV-1 reverse transcriptase (RT) are presented. The activity of the compounds synthesized as inhibitors of different types of HIV-1 RT (wild type enzyme and mutant forms P236L, Y181C and P236L/Y181C) was evaluated. The activity of the most active compounds was investigated in the syncytia reduction in vitro assay, in HIV-1(IIIB)-infected HT4lacZ-1 cells. Their potential cytotoxicity was determined in parallel. Two lead compounds, N-[1-[2-(3-isopropylamino)pyridyl]piperazin]-5,6-methylenedioxy indol-2-carboxamide 7q and N-[1-[2-(3-ethylamino)pyridyl]piperazin] 7s have been identified.

phosphine-catalyzed [4+3] annulation between dinucleophilic indole derivatives and Morita−Baylis−Hillman (MBH) carbonates was discovered by using the N1 and N4′/C4′ nucleophilicities of the indole precursors, in which indoles act as four atom synthons. This protocol provides an efficient and facile access to indole-1,2-fused 1,4-diazepinones and azepines in good to high yields in one step, which illustrates potential
