Molecular docking studies on binding specificity of 3,6- and 2,7-carbazoles with DNA duplexes
European Journal of Biological Research, 2020 Molecular docking is a widely used computational technique used to find the probabilistic binding sites of drugs in the vicinity of macromolecules. The drugs produce their working effect only when they bind and interact with the target macromolecule. The

Antimicrobial activity of 5,6-dihydrobenzo-[a]-carbazoles.
, 1994 peer reviewedA new series of 5,6-dihydrobenzo[a]carbazoles was synthesized, some showing good antibacterial activity. The presence of a dialkylamino ethyl chain on the 2-, 3- or 4-O-substituent seems to be critical for such ...

Synthesis of Benzo[a]carbazoles through Visible Light-Induced Cycloaromatization
We report herein a synthesis of 5,6-diarylbenzo[a]carbazoles by a sequence of 6 pi-electrocyclization followed by beta-elimination. The highly functionalized 2,3-disubstituted indoles used for this cycloaromatization process are prepared by Pd-catalyzed ...
