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.
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.

Alcoholic hepatitis (AH) is associated with liver neutrophil infiltration through activated cytokine pathways leading to elevated chemokine expression. Super-enhancers are expansive regulatory elements driving augmented gene expression. Here, we explore the mechanistic role of super-enhancers linking cytokine TNFα with chemokine

Most gastrointestinal stromal tumors (GISTs) contain KIT or PDGFRA kinase gain-of-function mutations, and therefore respond clinically to imatinib and other tyrosine kinase inhibitor (TKI) therapies. However, clinical progression subsequently results from selection of TKI-resistant clones, typically containing secondary mutations in
