(3β,7β,12β,20Z)-3,7,12-Trihydroxy-11,15,23-trioxo-lanost-8,20-dien-26-oic acid, a lanostane triterpenoid, demonstrates significant inhibitory effects on nitric oxide (NO) production in BV-2 microglia cells induced by n LPS, with an IC50 value of 9.55 uM. Moreover, this compound possesses anti-inflammatory properties.
18-Hydroxy-11-deoxy Corticosterone (18-OH-DOC) is a mineralocorticoid produced by the zona fasciculata of the adrenal gland, with its biosynthesis regulated by adrenocorticotropic hormone (ACTH) and angiotensin II. This regulation heightens 18-OH-DOC production in isolated human adrenal glomerulosa cells and allows for its formation from 11-deoxy corticosterone (DOC) in human SK-MEL188 melanoma cells. As an intermediate in progesterone metabolism, 18-OH-DOC can be converted to aldosterone in rat adrenal glands' capsular portion. Its continuous infusion (200 μg rat per day) has been shown to raise systolic blood pressure in uninephrectomized saline-drinking rats, and elevated plasma levels of 18-OH-DOC have been observed in the adb db mouse model of type 2 diabetes.
3β-Acetoxy-urs-11-en-28,13-olide exhibits significant protein tyrosine phosphatase 1B (PTP1B) inhibitory activity, it is a mixed-type PTP1B inhibitor. It exhibits weak-moderate antiproliferative activity against the A2780 human ovarian cancer cell line.
3β-Hydroxy-urs-11-en-28,13β-olide shows a potent concentration-independent cytoprotective effect against CCl4-induced injury on human hepatoma cell line relative to silymarin as a reference standard. It exhibits weak-moderate antiproliferative activity ag
