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.

Naturally occurring triterpenoid compounds have long been used as anti-inflammatory, antimalarial, and insecticidal agents. It has become evident that some of the natural or synthetic triterpenoids have promising clinical potential as both a therapeutic and chemopreventive agent for cancer. However

Pristimerin and celastrol isolated from the roots of Celastrus hypoleucus (Oliv) Warb f argutior Loes exhibited inhibitory effects against diverse phytopathogenic fungi. Pristimerin and celastrol were found to inhibit the mycelial growth of Rhizoctonia solani Kuhn and Glomerella cingulata (Stonem)

Inducible nitric oxide synthase dependent production of nitric oxide (NO) plays an important role in inflammation. We investigated whether pristimerin ((20alpha)-3-hydroxy-2-oxo-24-nor-friedela-1(10),3,5,7-te traen-carboxylic acid-(29)-methylester), an antitumoral, antimicrobial as well as anti-inflammatory plant compound, has an effect on the inducible NO synthase

Pristimerin is a triterpenoid isolated from Celastrus and Maytenus spp. that has been shown to possess a variety of biological activities, including anti-cancer activity. However, little is known about pristimerin's effects on tumor angiogenesis. In this study, we examined the

A combined treatment with conventional chemotherapies can enhance the effectiveness of chemotherapeutic agents against cancers. Here, we have shown that the naturally occurring triterpenoids synergistically enhance the response of cervical cancer cells to taxol. Of the triterpenoid compounds, pristimerin enhanced
