(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
