Alisol B
Based on 1 publication(s) in Google Scholar
Alisol B is a triterpene with diverse biological activities. Alisol B binds human soluble epoxide hydrolase (sEH) with a Ki of 5.97 μM and reduces sEH activity. Alisol B inhibits RANKL-induced JNK phosphorylation, NFATc1 and c-Fos expression, osteoclast formation, mature osteoclast pit-forming and actin ring activity, and SERCA pump activity. Alisol B induces calcium mobilization, CaMKK-AMPK-mTOR pathway activation, autophagic flux, autophagosome formation, G1 phase cell cycle arrest, endoplasmic reticulum stress, unfolded protein responses, and cancer cell apoptosis. Alisol B can be used for the research of hypercalcemia, osteoporosis, rheumatoid arthritis, periodontitis, acute kidney injury, and breast cancer.
