overview | pseudolaric acid B,PAB) is a diterpenoid compound in Tiferum. Modern pharmacological studies have shown that Acetic acid has anti-tumor, anti-fertility, anti-angiogenesis, anti-fungal, and activates peroxisome proliferator-activated receptor (PPAR) and other effects. |
biological activity | Pseudolaric Acid B is a diterpene acid isolated from the root of the Pseudolarix kaempferi Gorden (pinaceae). It has anti-cancer, anti-fungal, anti-fertilization activities, and also has immunosuppressive activity on T lymphocytes. Pseudolaric Acid B inhibits hepatitis B virus (HBV) secretion through apoptosis and cell cycle arrest. Acid B was Pseudolaric to induce autophagy. |
chemical properties | white crystalline powder, soluble in chloroform, acetone, methanol, derived from wattle skin, stiletto. |
use | td> tb acetic acid has antibacterial, anti-inflammatory and anti-cancer effects. used for content determination/identification/pharmacological experiment, etc. Pharmacological effect: It has obvious anti-fertility effect on rats, hamsters, rabbits and dogs. It has antifungal effect on Candida albicans, Trichophyton and Saccharomyces cerevisiae. |
