Withania somnifera

Withaferin A is a steroidal lactone isolated from Withania somnifera, inhibits NF-kB activation and targets vimentin, with potent antiinflammatory and anticancer activities. Withaferin A is an inhibitor of endothelial protein C receptor (EPCR) shedding.

Withanolide B is an active component of W. somnifera Dunal. Withanolide B promotes osteogenic differentiation of hBMSCs via ERK1/2 and Wnt/β-catenin signaling pathways. Withanolide B exhibits neuroprotective, anti-arthritic, anti-aging and anti-cancer effects.

Sominone is the active metabolite of Withanoside IV (HY-N8693). Sominone enhances neuronal morphological plasticity by activating the RET pathway. Sominone can also induce axon/dendrite regeneration and synaptic reconstruction, thereby improving spatial memory. Sominone can be used in the research of neurodegenerative diseases such as Alzheimer's disease.

Withanone is an active ingredient from the roots of Withania somnifera and a GRP75 inhibitor. Withanone has multifunctional neuroprotective effects in alleviating cognitive dysfunction. In neuron-like cells, Withanone can inhibit NMDA-induced excitotoxicity. Withanone can inhibit white adipose tissue browning by blocking the formation of the GRP75-ANT2-UCP1 complex, thereby alleviating cancer-related cachexia. Withanone can be used in the research of tumors and nervous system diseases.

Dihydrowithaferin A (2, 3-dihydrowithaferin A) is a withanolide isolated from Withania somnifera. Dihydrowithaferin A is active against acetylcholinesterase (AChE).

Withanoside IV is an orally active, blood-brain barrier-permeable withanolide derivative. Withanoside IV specifically binds to the Sudlow I site of HSA, induces secondary structural changes in HSA, and forms stable HSA complexes. Withanoside IV inhibits the enzymatic activity of COX-2. Withanoside IV induces axonal regeneration, peripheral nervous system myelination and increased axonal density in spinal cord tissue, reduces reactive gliosis-related changes, and improves hindlimb motor function. Withanoside IV binds to amyloid-β 1-42 to inhibit its aggregation, induces neurite outgrowth and synapse reconstruction, repairs damaged axons and dendrites, enhances mitochondrial biogenesis, exerts neuroprotective effects via the BDNF and SIRT1 signaling pathways, reduces ROS production and neuronal apoptosis, and ameliorates memory deficits. Withanoside IV inhibits the activity of the SARS-CoV-2 main protease. Withanoside IV can be used in research related to spinal cord injury, Alzheimer's disease, and coronavirus disease 2019 (COVID-19).

Withaferin A (Standard) is the analytical standard of Withaferin A. This product is intended for research and analytical applications. Withaferin A is a steroidal lactone isolated from Withania somnifera, inhibits NF-kB activation and targets vimentin, with potent antiinflammatory and anticancer activities. Withaferin A is an inhibitor of endothelial protein C receptor (EPCR) shedding.

Withanoside V is a blood-brain barrier-permeable withanolide derivative. Withanoside V binds strongly to Sudlow I (domain IIA) of human serum albumin (HSA) to form a stable complex and alter the secondary structure of albumin, thereby increasing helix content and reducing β-sheet and random coil. Withanoside V binds to Aβ (1-42) to block the interaction between monomers and subsequent aggregation. Withanoside V inhibits the viability of neuroblastoma cells, reduces the number of apoptotic cells induced by Aβ (1-42), and decreases ROS production. Withanoside V inhibits SARS-CoV-2 M_pro. Withanoside V can be used for research on Alzheimer's disease and coronavirus disease 2019.

Withasomniferolide B is a withanolide. Withasomniferolide B can be isolated from a GABAA receptor positive activator methanol extract of the roots of Withania somnifera.

2,3-Dihydro-3-methoxywithaferin A is an analogue of 2,3-dihydrowithaferin-A. 2,3-Dihydro-3-methoxywithaferin A inhibits proiiferation of P388 cells[1].

Viscosalactone B is a withanolide found in Withania somnifera. Viscosalactone B shows potent inhibitory activities to NCI-H460, HCT-116, MCF-7 and SF-268 cancer cells with IC₅₀ values of 0.32, 0.47, 0.4 and 0.45 μg/mL. Viscosalactone B can be used for the research of cancer.
