Application

Pristimerin has been used as an anti-tumor agent to study its effects on conditionally reprogrammed patient-derived lung adenocarcinoma cells (CRLCs). It has also been used as an anti-tumor agent to study its effects on conditionally reprogrammed patient derived-primary hepatocellular carcinoma cells (CRHCs).

Actions biochimiques/physiologiques

More active than euphol against MGL, better activity with rat neurons, but less selective relative to similar enzymes. First MGL inhibitor to act reversibly, several others covalently bind to cysteine residues. Other studies involve multiply mylome, pristimerin inhibits NF-κB activation via inhibition of IKK-α or IKK-β. It is the methyl ester of celastrol (C0869).
Pristimerin is a quinone methide triterpenoid found abundantly in Celastraceae and Hippocrateaceae families. It shows anti-inflammatory, anti-malarial, anti-bacterial, and insecticidal properties. Pristimerin exhibits anti-cancer and anti-proliferative activity by affecting vasculogenesis, apoptosis, autophagy, migration, and invasion of tumor cells. It has been studied to exhibit therapeutic effects against leukemia, glioma, breast cancer, prostate cancer, oral cancer, and lung cancer.
