RESUMEN
This study reports the design, synthesis, and comprehensive biological evaluation of 13 benzodioxolane derivatives, derived from the core structure of piperine, a natural product with established antitumor properties. Piperine, primarily found in black pepper, has been noted for its diverse pharmacological activities, including anti-inflammatory, antioxidant, and anticancer effects. Leveraging piperine's antitumor potential, we aimed to enhance its efficacy through structural modifications. Among the synthesized compounds, HJ1 emerged as the most potent, exhibiting a 4-fold and 10-fold increase in inhibitory effects on HeLa and MDA-MB-231 cell lines, respectively, compared to piperine. Furthermore, HJ1 demonstrated a favorable safety profile, characterized by significantly lower cytotoxicity towards the human normal cell line 293T. Mechanistic investigations revealed that HJ1 markedly inhibited clonogenicity, migration, and adhesion of HeLa cells. In vivo studies utilizing the chick embryo chorioallantoic membrane (CAM) model substantiated the robust antitumor activity of HJ1, evidenced by its ability to suppress tumor angiogenesis and reduce tumor weight. These results suggest that HJ1 holds significant promise as a lead compound for the development of novel antitumor therapies.
