Celastrol
chemical compound
Celastrol (tripterine) is a bioactive chemical compound isolated from the roots of Tripterygium wilfordii (Thunder duke vine) and Tripterygium regelii (Regel's threewingnut). Celastrol is a pentacyclic nortriterpen quinone and belongs to the family of quinone methides. It has been used for centuries as a traditional Chinese medicine. In recent years, celastrol has been widely studied for its anti-inflammatory, anticancer, antioxidant, and antibacterial properties.
In mice, celastrol is an NR4A1 agonist that alleviates inflammation and induces autophagy. It also influences metabolic regulation by enhancing IL1R1 expression, which is the receptor for the cytokine interleukin-1 (IL-1). IL1R1 knock-out mice exposed to celastrol exhibit no leptin-sensitizing or anti-obesity effect.
In in vitro and in vivo animal experiments, celastrol exhibits antibacterial, antioxidant, anti-inflammatory, anticancer, and insecticidal properties. It has been shown to have obesity-controlling effects in mice by inhibiting negative regulators of leptin. Celastrol has also shown to possess anti-diabetic effects on diabetic nephropathy and improve whole-body insulin resistance, through the inhibition of NF-κB signaling in the hypothalamus.
The public source identifies “Celastrol” as chemical compound. This brief keeps that definition visible, then builds a research path around Celastrol, chemical and compound.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Celastrol”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q5057534. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
