SIAIS178 (C09-1170-039)

SIAIS178 is a potent and selective BCR-ABL degrader based on PROTAC technology with an IC 50 of 24 nM. SIAIS178 causes effective degradation of BCR-ABL protein by recruiting Von Hippel-Lindau (VHL) E3 ubiquitin ligase. SIAIS178 has anticancer activityIn VitroSIAIS178 (1-100 nM; for 16 hours) significantly reduces the BCR-ABL protein levels in a concentration dependent manner. SIAIS178 significantly inhibits the phosphorylation of BCR-ABL and the substrates STAT5. SIAIS178 (1, 10, 100, 1000 nM) exerts significant antiproliferative activity in BCR-ABL driven CML cell lines. SIAIS178 retains potency and selectivity against the BCR-ABL driven cell lines. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
