Several 6-substituted tetrahydrocarbazole derivatives were designed, synthesized and evaluated for the antibacterialactivities against Staphylococcus aureus Newman strain. Subsequently, 2,4-diaminopyrimidine scaffold was merged with the tetrahydrocarbazole unit to generate a series of novel hybrid derivatives and the antibacterialactivities were also investigated. Among these novel hybrids, compound
设计,合成和评价了几种6-取代的四氢咔唑衍生物对金黄色葡萄球菌Newman菌株的抗菌活性。随后,将2,4-二氨基嘧啶支架与四氢咔唑单元合并以生成一系列新型杂化衍生物,并研究了其抗菌活性。在这些新型杂种中,化合物12c对金黄色葡萄球菌Newman和大肠杆菌AB1157菌株的活性最强,MIC为0.39–0.78μg/ mL 。另外,化合物12c对一组金黄色葡萄球菌的多重耐药菌株表现出低MIC值。

Abstract A convenient synthesis of 1-oxo-1,2,3,4-tetra-hydrocarbazoles has been developed by reaction of 2-aminocyclohexanone hydrochlorides with various phenylhydrazine hydrochlorides viaFischerindolesynthesis under mild conditions. The method is more satisfactory in terms of the easy availability of starting materials and the simple one-pot operation.

A series of new 5,6,11,12-tetrahydroindolo[2,3-a]carbazole derivatives (3a-h) was synthesized. Treatment of 8-methyl-1-oxo-1,2,3,4-tetrahydrocarbazole (1a) with phenylhydrazine hydrochloride in ethanol furnished the title compound (3a) in poor yield along with 8-methyl-1-phenylhydrazono-1,2,3,4-tetrahydrocarbazole (2a). Better yields were obtained when la-h were treated with phenylhydrazine in glacial acetic acid. All the newly synthesized compounds were characterized on the basis of IR, NMR, mass-spectra and elemental analysis and screened for pharmacological activities. (C) 2001 Elsevier Science S.A.
