Description: | NI-42 is a potent, selective and orally active BRPF1 bromodomain inhibitor with IC50 of 7.9 nM, with excellent selectivity over nonclass IV BRDs; weakly inhibits BRPF2 (BRD1), BRPF3, BRD9 and BRD4 (BD1) with IC50 of 48, 260, 310 and 4500 nM respectively, and no activity for ATAD2A/2B (IC50>100 uM); shows a modest (GI50=1-10 uM) and selective inhibition of proliferation of certain cancer lines, particularly those lines exhibiting monocytic lineage differentiation; a novel, structurally orthogonal chemical probe for the BRPFs suitable for cellular and in vivo studies. |
Target: | BRPF1:7.9 nM (IC50) BRPF2:48 nM (IC50) BRPF3:260 nM (IC50) BRPF1:40 nM (Kd) BRPF2:210 nM (Kd) BRPF3:940 nM (Kd) BRD4 (BD1):4500 nM (IC50) BRD7:82 nM (IC50) BRD9:310 nM (IC50) BRD9:1130 nM (Kd) |
In Vitro: | NI-42 shows IC50s of 82, 310, and 4500 nM for BRD7, BRD9, and BRD4 (BD1), respectively, and has a Kd of 1130 nM for BRD9[1]. |
