Abstract:
The heterocyclic vanilloid compound capsaicin is responsible for the spicy and pungent flavor of chili peppers. Several convergent studies have shown that capsaicin suppresses the growth of multiple human cancers. Apart from capsaicin, natural and synthetic capsaicin-like compounds display growth suppressive activity in human cancers. The pharmacophore of capsaicin is comprised of three regions, namely region A (the aromatic ring), region B (the amide bond), and region C (the side chain). The present manuscript describes the isolation and synthesis of capsaicin analogs which have structural modifications in region B of the molecule. Furthermore, the pharmacokinetic properties, anticancer activity of region B capsaicin analogs, as well as the signaling pathways (underlying the growth-inhibitory effects of region B capsaicin analogs) have also been described. The discovery of novel, second-generation region B capsaicin analogs may foster the hope of innovative nutrition-based combination therapies in human cancers.
