Indazole scaffold: a generalist for marketed and clinical drugs

More and more attention has been paid to the structurally diverse indazole analogs in recent years which are widely present in numerous commercially available drugs. Indazole-containing derivatives are endowed with a broad range of biological properties, such as anti-inflammatory, antibacterial, anti-HIV, antiarrhythmics, antifungal and antitumor activities. This review is a guide for pharmacologists who are in search of valid preclinical/clinical drug compounds where the progress, from 1966 to the present day, of approved marketed drugs containing indazole scaffold is examined.
