Alkaloids represent an important group of molecules that have immense pharmacological potential. Benzophenanthridine alkaloids are one such class of alkaloids known for their myriad pharmacological activities that include potential anticancer activities. Chelerythrine is a premier member of the benzophenanthridine family of the isoquinoline group. This alkaloid is endowed with excellent medicinal properties and exhibits antibacterial, antimicrobial and anti-inflammatory properties. The molecular basis of its therapeutic activity is considered due to its nucleic acid binding capabilities. This review focuses on consolidating the current status on the nucleic acid binding properties of chelerythrine that is essential for the rational design and development of this alkaloid as a potential drug. This work reviews the interaction of chelerythrine with different natural and synthetic nucleic acids like double- and single-stranded DNAs, heat-denatured DNA, quadruplex DNA, double- and single-stranded RNA, tRNA and triplex and quadruplex RNA. The review emphasizes on the mode, specificity, conformational aspects and energetics of the binding that is particularly helpful for developing nucleic acid targeted therapeutics. The fundamental results discussed in this review will greatly benefit drug development for many diseases and serve as a database for the design of futuristic benzophenanthridine-based therapeutics.
