I-BET567 is a potent and orally active inhibitor of pan-BET candidate with pIC₅₀s of 6.9 and 7.2 for BRD4 BD1 and BD2, respectively. I-BET567 has been demonstrated efficacy in mouse models of oncology and inflammation^[1].

I-BET567 (compound 27) (72 hours; 1.5 nM-30 μM) effectively inhibites the proliferation of human NMC cell line 11060 in vitro with a mean gpIC₅₀ 6.2 (0.63 μM)^[1].

I-BET567 (compound 27) (3, 10, and 30 mg/kg; p.o.; once daily for 20 days) leads to a significant reduction in tumor growth compared with vehicle controls at both 10 and 30 mg/kg^[1].
