Based on the fact that timosaponin A-III (TA-III) exhibits potent cytotoxic effects and has been considered as a potential anti-tumor agent, a range of novel sarsasapogenin derivatives 1, 2a-2g, 3, 4, 5, 6a-6g have been synthesized by a simple and facile synthetic route. The in vitro cytotoxic
Based on the fact that Timosaponin A-III, a saponin isolated from the rhizome of Anemarrhena asphodeloides, is a promising bioactive lead compound in the treatment of cancer, structural modification at the C3 and C26 positions of sarsasapogenin has always been the focus of our structure-activity
Sarsasapogenin derivative 5n (SGD 5n) is a new compound with potent antitumor efficacy, but the low solubility severely affects its absorption and bioavailability. Therefore, the SGD 5n-loaded mPEG-PLGA block copolymer micelles were developed to improve the value of SGD 5n in clinical application.
Sarsasapogenin, a kind of mainly effective components of Anemarrhena asphodeloides Bunge (Liliaceae) has the effects of being anti-diabetes and improving memory. However, there are few reports focusing on its anti-tumor effects. In this study, the sarsasapogenin was extracted from rhizomes of A.
Sarsasapogenin, a kind of mainly effective component of Anemarrhena asphodeloides Bunge, possesses good antitumor properties. Two series of new sarsasapogenin derivatives were synthesized and evaluated for their cytotoxicities against three human cancer cell lines (HepG2, A549, MCF-7) using the MTT
The rhizome of Anemarrhena asphodeloides (AA, family Liliaceae), which contains furostanol and spirostanol saponins, is a typical herbal medicine that improves learning and memory in rats and inhibits inflammation. In a preliminary study, timosaponin AIII, one of AA main constituents, was
Timosaponin A-III (TAIII), a saponin isolated from the rhizome of Anemarrhena asphodeloides, exhibits potent cytotoxicity and has the potential to be developed as an anticancer agent. Here, we provide evidence that TAIII induces autophagy in HeLa cells followed by apoptotic cell death. TAIII-induced
The naturally derived trisaccharide steroidal saponin 1 and structurally modified derivatives 2 and 3 bearing the same sarsasapogenin aglycon were synthesized concisely via a direct transglycosylation strategy. The antitumor activities of the synthetic trisaccharide saponins 1-3 and their
One new (Sarsasapogenin O) and seven known steroids were isolated from the roots of Asparagus officinalis L. Their structures were elucidated on the basis of spectroscopic analysis, including various 2D-NMR techniques, hydrolysis, and by comparison of spectral data of known compounds. These
Steroids are perhaps one of the most widely used group of drugs in present day. Beside the established utilization as immunosuppressive, anti-inflammatory, anti-rheumatic, progestational, diuretic, sedative, anabolic and contraceptive agents, recent applications of steroid compounds include the
