Analogues of Withanolide E Sensitize Cancer Cells Toward Apoptosis
Abstract: The tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) protein has been a target of interest in cancer therapy because it plays a large role in inducing cell apoptosis in cancer cells but not in normal cells.  Although TRAIL has been reported to successfully target certain tumor cells which are resistant to traditional chemotherapy...

An Efficient And Improved Chemical Conversion Of The Natural Product Physachenolide D (LG-01) To Its Analogue LG-134 With Potent Anticancer Activity
Invention: An improved process of chemical conversion of the natural plant product physachenolide D (PCD) to a C-18 analogue (LG-134) of physachenolide C (PCC).Background: The standard yield of LG-134 using current methods is relatively low at 1/3 resultant from original products. This method allows for the yield to be double current chemical processes....

Specific 17-Beta-Hydroxywithanolides Sensitize Cancer Cells to Apoptosis in Response to Toll-like Receptor (TLR)
This invention describes the use of physachenolide C for cancer treatment through cancer cell apoptosis (cell self-destruction) through extrinsic pathways of “death ligand” proteins. Physachenolide C is a natural product in which the 17-beta-hydroxy group and orientation of the molecule chain result in improved apoptosis sensitivity, with...

Semi-Synthetic 17beta-Hydroxywithanolides (17-Bhws) Promote Caspase-8-Dependent Apoptosis in Renal Carcinoma and Melanoma and Specifically Inhibit Human Prostate Cancer Cell Proliferation
This novel, partially naturally-derived compound can be used to treat three different kinds of cancer (melanoma, renal carcinoma, and prostate cancer) in patients without other treatment options. Background: The treatment of all kinds of cancers leaves much to be desired in terms of an efficient treatment that is highly effective and has comparably...

A Water-Soluble Prodrug for the Heat Shock-Inducing Compound Withaferin A
University of Arizona researchers have developed an economically viable and environmentally friendly method for producing and isolating large quantities of both Withaferin A and the novel withanolides. Aeroponic cultivation is a significant achievement as acquiring an abundant supply of starting material is often a significant hurdle in the development...

Natural Product Modulators of Stress Response
In response to many stresses, including heat, oxidizing conditions, and exposure to toxic compounds, plant cells up-regulate an evolutionarily conserved set of helper molecules known as heat shock proteins (Hsp). Increased expression of these proteins protects the organism against stress-induced damage. The investigators have isolated a secondary...
