Benzothiazole is a privileged bicyclic ring system with multiple applications. A large number of therapeutic agents are synthesized with the help of benzothiazole nucleus. Benzothiazole nucleus is found to possess a number of biological activities such as anticancer, antimicrobial, antidiabetic, anti-...
