[Novel derivatives of diosgenin: design, synthesis and anti-tumor activity].

Diosgenin can inhibit the growth of A375 and K562 cell lines and induce their apoptosis with an effect on pro-apoptotic members of Bcl-2 family. To study the SAR of diosgenin derivatives, and to improve the anti-tumor activity of diosgenin, a series of novel diosgenin derivatives were designed and synthesized. Their anti-tumor activities in vitro were evaluated.
