Exploration of newer possibilities to the synthesis of diazepine and quinoline carboxylic acid derivatives

Abstract

Heterocyclic systems containing benzothiazoles, carbazole (and azacarbazole) moieties have attracted the attention of chemists owing to these nuclei having been identified in the literature as most promising pharmacophores in drug design and synthesis. Based on these observations, it could be anticipated that incorporation of the bioactive azepine moiety and quinoline moiety into the molecular framework of benzothiazoles fused to carbazole (and azacarbazoles) could produce interesting series of compounds 912 with enhanced biological activities, whose structure was unequivocally established from its microanalyses and spectral data. © 2013 Vatsala Soni et al.
