Chaetocin (Chetocin)
Chaetocin is an epithiodioxopiperazine antibiotic that has recently shown promise as a selective antitumor agent. Chaetocin is a specific inhibitor for the lysine-specific methyltransferase SU(VAR)3-9 both in vitro and in vivo. Chaetocin is dramatically accumulated in cancer cells via a process inhibited by glutathione. Inside the cell, its activity is mediated by the imposition of oxidative stress. Group: Biochemicals. Alternative Names: Chetocin. Grades: Highly Purified. CAS No. 28097-03-2. Pack Sizes: 1mg. US Biological Life Sciences.
