Product Overview:
Withaferin A is a steroidal lactone that has been found in W. somnifera with diverse biological activities.{21343,21342} It binds to and induces aggregation of vimentin intermediate filaments in cultured endothelial cells and fibroblasts, inducing apoptosis when used at concentrations ranging from 2 to 25 μM. It also induces formation of perinuclear aggregates in other intermediate filament networks including peripherin, neurofilament-triplet protein, and keratin as well as disrupts the organization of microtubules and actin/microfilaments.{21342} Withaferin A induces noncanonical ferroptosis via induction of lipid peroxidation through interaction with Kelch-like ECH-associated protein 1 (KEAP1) in IMR-32 neuroblastoma cells, an effect that is blocked by the ferroptosis inhibitors ciclopirox olamine and ferrostatin-1 (Item No. 17729).{35972} It also binds to and inhibits glutathione peroxidase 4 (GPX4) in IMR-32 cells. In vivo, withaferin A (4 mg/kg) reduces intratumor GPX4 expression and induces tumor regression in an IMR-32 mouse xenograft model. Withaferin A (2 mg/kg) also inhibits angiogenesis in a mouse model of injury-induced corneal neovascularization.{21343}

Cayman Chemical's mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.

Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.

Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.

Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
