Celastrol (tripterine) is a chemical compound isolated from the root extracts of Tripterygium wilfordii (Thunder god vine) and Celastrus regelii. Celastrol is a pentacyclic triterpenoid and belongs to the family of quinone methides.

In in vitro and in vivo animal experiments, celastrol exhibits antioxidant,[2] anti-inflammatory,[3][4] anticancer,[5][6][7][8] and insecticidal [9] activities. It has been shown to have obesity-controlling effects in mice.[10] Celastrol has also shown to possess (by inhibition of NF-κB in the hypothalamus[11]) anti-diabetic effects on diabetic nephropathy and improve whole-body insulin resistance[12][13]
