| Withaferin A is a steroidal lactone derived from the medicinal plant Withania somnifera (commonly known as Ashwagandha). The main active constituents of Ashwagandha leaves are alkaloids and steroidal lactones (commonly known as Withanolides). -The main constituents of ashwagandha are withanolides such as withaferin A, alkaloids, steroidal lactones, tropine, and cuscohygrine. Ashwagandha is an herb that may reduce stress, anxiety, and insomnia. *-Ashwagandha is often characterized as an antioxidant. -Some studies suggest that while ashwagandha may protect normal cells from oxidative damage, it can simultaneously stress cancer cells by tipping their redox balance toward cytotoxicity. Pathways: -Induction of Apoptosis and ROS Generation -Hsp90 Inhibition and Proteasomal Degradation Cell culture studies vary widely, typically ranging from low micromolar (e.g., 1–10 µM). In animal models (commonly mice), Withaferin A has been administered in doses ranging from approximately 2 to 10 mg/kg body weight. - General wellness, Ashwagandha supplements are sometimes taken in doses ranging from 300 mg to 600 mg of an extract (often standardized to contain a certain percentage of withanolides) once or twice daily. - 400mg of WS extract was given 3X/day to schizophrenia patients. report#2001. - Ashwagandha Pure 400mg/capsule is available from mcsformulas.com. -Note half-life 4-6 hrs?.

| α-smooth muscle actin (α-SMA) is a protein that is often associated with cancer progression. It is a key component of the actin cytoskeleton and plays a crucial role in cell migration, invasion, and contraction. α-SMA is often expressed by cancer-associated fibroblasts (CAFs), which are a type of stromal cell that surrounds the tumor. CAFs expressing α-SMA can promote tumor growth and metastasis. High levels of α-SMA expression have been correlated with poor prognosis in various types of cancer, including breast, lung, and colorectal cancer. |
