Isatin Derivatives

Indole and its derivatives have engaged a unique place in the chemistry of nitrogen heterocyclic compounds. The recognition of the plant growthhormone, heteroauxin, the significant amino acids, tryptamine & tryptophan and anti-inflammatory drug, indomethacine are the imperativederivatives of indole which have added stimulus to this review work. Isatin (1H-indole-2,3-dione), an indole derivative of plant origin. Althoughit is a naturally occurring compound, but was synthesized by Erdmann and Laurent in 1840 before it was found in nature. Isatin is a versatileprecursor for many biologically active molecules and its diversified nature makes it a versatile substrate for further modifications. It is concernedin many pharmacological activities like anti-malarial, antiviral, anti-allergic, antimicrobial etc; isatin and its derivatives have been also found todemonstrate promising outcomes against various cancer cell lines. This review provides a brief overview on the recent advances and futureperspectives on chemistry and biological aspects of isatin and its derivatives reported in the recent past.

Nitrogen-containing heterocycles are one of the most common structural motifs in approximately 80% of the marketed drugs. Of these, benzimidazoles analogues are known to elicit a wide spectrum of pharmaceutical activities such as anticancer, antibacterial, antiparasitic, antiviral, antifungal as well as chemosensor effect. Based on the benzimidazole core fused heterocyclic compounds, crescent-shaped bisbenzimidazoles were developed which provided an early breakthrough in the sequence-specific DNA recognition. Over the years, a number of functional variations in the bisbenzimidazole core have led to the emergence of their unique properties and established them as versatile ligands against several classes of pathogens. The present review provides an overview of diverse pharmacological activities of the bisbenzimidazole analogues in the past decade with a brief account of its development through the years.
