Potent PARP1 Degrader (PROTAC®)
Product Description
SK 575 is a potent PARP1 Degrader (PROTAC®; DC50 ≤ 6.72 nM, >99% PARP1 degradation at 10 nM). It comprises the PARP1/2 inhibitor Olaparib (Cat. No. 7579), joined by a linker to cereblon/cullin 4A ligand Thalidomide (Cat. No. 0652). SK 575 inhibits the growth of various cancer cell lines bearing BRCA1/2 mutations with IC50 values in the nanomolar range. It effectively reduces PARP1 protein levels in mouse SW620 tumor xenograft models. SK 575 dose-dependently potentiates the antitumor activity of Temozolomide (Cat. No. 2706) and Cisplatin (Cat. No. 2251) in vivo.PARP antibodies validated for Simple Western™ (automated Western) instruments and Western Blot also available: Catalog # AF-600-NA and MAB8095.
