Objective: Ce/astrus orbicu/atus Thunb. has been used for thousands of years in China as a remedy against cancer and inflammatory diseases. This study aims to investigate whether C. orbiculatus extract (COE) could ...
A series of newly 1,3,4-oxadiazole-2-thioglycoside derivatives were synthesized. The key step of this protocol is the coupling between 5-herteroaryl-1,3,4-oxadiazole-2-thione and activated sugars (cyclic or acyclic su...
Grifolin,a secondary metabolite isolated from the fresh fruiting bodies of mushroom Albatrellus confluens,inhibits the growth of some cancer cell lines in vitro by induction of apoptosis in the previous studies of our...

Numerous attempts have been made to select compounds that might reduce the incidence of cancer. Previously we have found out that several kinds of natural and
Maytansine (I) (C34H46CIN3O10) is a novel type of ansa macrolide with potent antitumor activity. It was isolated by Kupchan et al. with great efforts from several Maytenus species (0.2 p.p.m.—1.5 p.p.m, dried plan...
