Diosgenin, a naturally occurring steroidal saponin, has been confirmed to possess potent anticancer properties. In the current work, two series of novel diosgenin derivatives bearing 1,3,4-oxadiazole (6a-6e and 7a-7e) or 1,3,4-thiadiazole (8a-8e and 9a-9e) moieties were designed, synthesized and evaluated for their cytotoxicities in four human cancer cell lines (HepG2, A549, MCF-7 and HCT-116) and normal human gastric epithelial cells (GES-1) using the MTT assay in vitro. The results showed that compounds 8d and 9d exhibited significant cytotoxic activities against the HepG2 and A549 cells, being more potent than their parent compound diosgenin.

Isorenieratene interaction with human serum albumin: Multi-spectroscopic analyses and docking simulation.

Isorenierantene was reported to be an aromatic carotenoid and has become a food ingredient, mainly from smear cheese, which possesses special antioxidant ability and significant photoprotective effect. In this paper, the interaction of isorenieratene with human serum albumin (HSA) was explored and compared with that of nonaromatic carotenoids using multi-spectroscopic methods and docking simulations. The results suggested isorenieratene could bind to HSA through a static quenching mechanism.
