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.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
