benzocphenanthridine
Benzophenanthridine is a class of organic compounds characterized by a fused ring system consisting of a benzene ring, a cyclopentadiene ring, and a pyridine ring. These structures are planar and aromatic. The core benzophenanthridine skeleton is found in a variety of naturally occurring alkaloids, particularly those derived from plants. These alkaloids often exhibit significant biological activities, leading to considerable interest in their synthesis and study.
The biosynthesis of benzophenanthridine alkaloids typically begins with amino acids like tyrosine. Through a series of
Some well-known benzophenanthridine alkaloids include sanguinarine and chelerythrine. These compounds have been investigated for a range
