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].Assessment of Pharmacokinetics (PK) profile of I-BET567 following intravenous infusion and oral administration in male wistar han rat and beagle doga[1]. species dose ivb/poc (mg/kg) CLb (mL/min/kg) CLb,u (mL/min/kg) CLrenal (mL/min/kg) Vss (L/kg) Vss,u (L/kg) t1/2 (h) Fpo (%) fub rat1.3/32510972.410.41.699d0.23 dog1.0/38.1206.91.22.91.8980.41a: Values are mean, n=3 unless otherwise stated. b: IV dose 1h infusion in DMSO and (10%, w/v) Kleptose HPB in saline (2%: 98% (v/v)). c: PO dose vehicle: 1%(w/v) methycellulose (400 cps) (aq). d: Mean n = 2.

Design, Synthesis, and Characterization of I-BET567, a Pan-Bromodomain and Extra Terminal (BET) Bromodomain Oral Candidate
J Med Chem 2022 Feb 10;65(3):2262-2287.PMID:34995458DOI:10.1021/acs.jmedchem.1c01747
Through regulation of the epigenome, the bromodomain and extra terminal (BET) family of proteins represent important therapeutic targets for the treatment of human disease. Through mimicking the endogenous N-acetyl-lysine group and disrupting the protein-protein interaction between histone tails and the bromodomain, several small molecule pan-BET inhibitors have progressed to oncology clinical trials. This work describes the medicinal chemistry strategy and execution to deliver an orally bioavailable tetrahydroquinoline (THQ) pan-BET candidate. Critical to the success of this endeavor was a potency agnostic analysis of a data set of 1999 THQ BET inhibitors within the GSK collection which enabled identification of appropriate lipophilicity space to deliver compounds with a higher probability of desired oral candidate quality properties. SAR knowledge was leveraged via Free-Wilson analysis within this design space to identify a small group of targets which ultimately delivered I-BET567 (27), a pan-BET candidate inhibitor that demonstrated efficacy in mouse models of oncology and inflammation.
