Common NameTriptolide
DescriptionTriptolide belongs to the class of organic compounds known as oxepanes. Oxepanes are compounds containing an oxepane ring, which is a seven-member saturated aliphatic heterocycle with one oxygen and six carbon atoms. Cys342 of XPB was identified as the residue that undergoes covalent modification by the 12,13-epoxide group of triptolide, and the XPB-C342T mutant rendered the T7115 cell line nearly completely resistant to triptolide. Several putative target proteins of triptolide have been reported, including polycystin-2, ADAM10, DCTPP1, TAB1, and XPB. Triptolide is an extremely weak basic (essentially neutral) compound (based on its pKa). Its Phase II clinical trials are expected to conclude in February 2019. In a preclinical mouse model of pancreatic cancer, it was "even more effective than gemcitabine". The level of resistance conferred by the C342T mutation is about 100-fold higher than the most triptolide-resistant mutants previously identified. Consequently, a synthetic water-soluble prodrug, minnelide, is being studied clinically instead. Triptolide is a diterpenoid epoxide which is produced by the thunder god vine, Tripterygium wilfordii. However, no triptolide-resistant mutations were found in polycystin-2, ADAM10, DCTPP1 and TAB1. Water-soluble prodrugs Minnelide is a more water-soluble synthetic analog of triptolide which is converted to triptolide in vivo. Triptolide is found in Tripterygium hypoglaucum and Tripterygium wilfordii . Glutriptolide, a glucose conjugate of triptolide with better solubility and lower toxicity, did not inhibit XPB activity in vitro, but exhibited tumor control in vivo, which is likely due to sustained stepwise release of active triptolide within cancer cells.
