| Product Description | CF53 is a highly potent, selective and orally active inhibitor of BET protein, with a K i of <1 nM, K d of 2.2 nM and an IC 50 of 2 nM for BRD4 BD1. CF53 binds to both the BD1 and BD2 domains of BRD2 , BRD3 , BRD4 , and BRDT BET proteins with high affinities, very selective over non-BET bromodomain-containing proteins. CF53 shows potent anti-tumor activity both in vitro and in vivo In Vitro CF53 (Compound 28) binds to both the BD1 and BD2 domains of BRD2, BRD3, BRD4, and BRDT BET proteins with high affinities, K d s are 1.1 nM (BRD2 BD1), 0.6 nM (BRD2 BD2), 0.52 nM (BRD3 BD1), 0.49 nM (BRD3 BD2), 0.8 nM (BRD4 BD2), 2 nM (BRDT BD1), 2.1 nM (BRDT BD2), 47 nM (CREBBP), 570 nM (CECR2), 110 nM (EP300), respectively. CF53 exhibits IC 50 s of 7, 85 nM against MOLM-13 acute leukemia and MDA-MB-231 breast cancer cell lines, respectively. MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo CF53 (25, 50 mg/kg, p.o.) exhibits potent anti-tumor activity both in MDA-MB-231 xenograft tumor model and in RS4;11 model in mice . MCE has not independently confirmed the accuracy of these methods. They are for reference only.
