Design, synthesis, molecular docking studies and anti-microbial activity of novel 1,2,3,4-tetrahydrocarbazole derivatives

Abstract

The heterocyclic compounds naming tetrahydrocarbazoles having the significant biological properties. The newly substituted tetrahydrocarbazole derivatives were prepared from substituted phenylhydrazine and cyclohexanone in glacial acetic acid under reflux. These intermediates on reaction with substituted aromatic acid chlorides in alkaline media finally converted to N-Substituted tetrahydrocarbazoles. Fifteen compounds are synthesized and characterized by their melting point (MP), IR, NMR, MS and elemental analysis. All the compounds were subjected to molecular docking studies for Gln-6-p enzyme (1XFF) inhibition. The results of in silico molecular docking showed that all the derivates have significant binding energies, good affinity with active pocket and it may be reflected as a good inhibitor of GlcN-6-P synthase. The anti-microbial activity was assessed by agar cup plate method and the result showed 8 compounds having the better anti-microbial response against the bacterial and fungal strains. In conclusion, the study helps to give the greater scope of developing these tetrahydrocarbazoles derivatives which help to promote the effective anti-bacterial agents.
