Abstract

Preclinical Research

The preparation of novel E-salignone derivatives and their biological evaluation as potential antimetastatic agents is described. The E-salignone amide derivatives were prepared from epiandrosterone and androsterone, and characterized by analytical 1H NMR, 13C NMR, and mass spectrometry. The derivatives were evaluated for antimetastatic activity in MDA-MB-231 cells by using a transwell assay. Comparing with the positive control, LY294002, compounds 19b, 19d, and 19e exhibited significant inhibitory effects on the EGF-induced invasion of MB-MDA-231 cells. Moreover, compound 19b also had antimigration effects in wound-healing assay. Compound 19b may represent a novel antimetastatic agent for treating breast cancer.
