Application

Celastrol has been:
  • used intraperitoneally to inject into experimental mice to study its role in nonalcoholic fatty liver disease (NAFLD)
  • used in culture medium to study its effect on lipopolysaccharide-induced inflammatory injury in human keratinocyte cell culture
  • used to study its effect in vitro and in vivo in VCaP cells

Biochem/physiol Actions

Celastrol is a potent antioxidant, and anti-inflammatory agent. It is a novel HSP90 inhibitor (disrupts Hsp90/Cdc37 complex), that exhibits anticancer (anti-angiogenic - suppresses VEGFR expression); antioxidant (inhibits lipid peroxidation) and anti-inflammatory activity (suppresses iNOS and inflammatory cytokine production).
Celastrol is a quinone methide triterpene naturally present in Tripterygium wilfordii. It is useful in treating rheumatoid arthritis. Celastrol prevents the action of proteasome and nuclear factor Κb.
