Benzophenanthridines are a class of chemical compounds that have a characteristic three-ring structure, consisting of two benzene rings fused to a phenanthrene ring. This structural core is found in several naturally occurring and synthetic compounds with various biological activities. Some benzophenanthridine alkaloids, such as sanguinarine and chelerythrine, have been studied for their antimicrobial, anti-inflammatory, and anticancer properties. However, it is essential to note that these compounds can also exhibit toxicity at higher concentrations, making their therapeutic use challenging.
