Abstract :

Cancer continues to be a major health concern and a number of deaths are caused by cancer that is second only to cardiovascular diseases. The development of compounds that target genes involved in cancer pathogenesis is a potential area of cancer drug discovery. A number of anticancer drugs employed clinically exert their effect by inhibiting nucleic acid (DNA or RNA) or protein synthesis. It is evident that DNA is an important cellular target for many anticancer agents. Pyrrolo[2,1-c][1,4]benzodiazepines (PBDs) are naturally occurring compounds isolated from various Streptomyces species. The PBDs exert their biological activity through covalent binding within the minor groove of DNA. Several PBD conjugates have been synthesized to investigate the detailed biological aspects relating to the mechanism of action. Some of the potent molecules like PBD-quinazolinones and PBD-diaryloxadiazoles have been evaluated for their in vivo efficacy studies. These studies suggest that such PBD conjugates have promising anticancer activity. Some of the PBD conjugates act as activators of p53 and suppressors of NF-κB and thereby they could be considered as promising anticancer agents with improved potential for the suppression of tumours. To improve the selectivity as well as stability, some new β-galactoside prodrugs of PBDs have been synthesized and evaluated for their potential use in selective therapy of solid tumors by ADEPT and PMT protocols. Another important property of these molecules is their enhanced water solubility and stability, which are essential for a molecule to be an effective drug.
