Catharanthine, an anticancer vinca alkaloid: an in silico and in vitro analysis of the autophagic system as the major mechanism of cell death in liver HepG2 cells.

Catharanthine, a component of the anticancer drug vinblastine along with vindoline, disrupts the cell cycle by interfering with mitotic spindle formation. Apart from their antioxidant properties, vinca alkaloids like catharanthine inhibit phosphodiesterase activity and elevate intracellular cAMP levels. The aim of this study was to investigate how catharantine affects apoptosis and autophagy.
