Description: OF-1 is a chemical probe for BRPF bromodomains. OF-1 has been shown to bind to BRPF1B with a KD of 100 nM (ITC), to BRPF2 with a KD of 500 nM (ITC) and to BRPF3 with a KD of 2.4 uM (ITC). Selectivity against other bromodomains is very good, in general >100-fold. The closest off-target effects are against BRD4 (39-fold selectivity) and TIF1a (50% inhibition at 20 µM in the alphascreen). OF-1 increases thermal stability in the cellular thermal shift assay (CETSA) of full length BRPF1B at 1 µM and also demonstrates accelerated FRAP recovery at 5 µM in the BRPF2 FRAP assay. It shows modest general cytotoxicity. (http://www.thesgc.org/chemical-probes/OF-1).
