Description

PYR-41 is a ubiquitin-activating enzyme inhibitor (UBE1 inhibitor). PYR-41 blocks ubiquitination reactions but paradoxically leads to the accumulation of high MW ubiquitinated proteins. PYR-41 also mediated cross-linking of specific protein kinases (Bcr-Abl, Jak2) to inhibit their signaling activity. PYR-41 has demonstrated anti-tumor activity in animal studies, partially selective protein cross-linking may represent an alternate approach to affect signal transduction modules and ubiquitin cycle-regulatory proteins for cancer therapy. (Biochem Pharmacol. 2011 Aug 15;82(4):341-9.) (Note: PYR-41 in solution may exist as a mixture of E- and Z- isomers. HPLC may show two peaks depending on conditions).
