产品描述 | BRD4/CK2-IN-1 is the first highly effective and oral active dual-target inhibitor ofBRD4/CK2(bromodomain-containing protein 4/casein kinase 2), withIC50s of 180 nM and 230 nM for BRD4 and CK2, respectively. BRD4/CK2-IN-1 has strong anticancer activity without obvious toxicities. BRD4/CK2-IN-1 inducesapoptosisandautophagy-associated cell death in triple-negative breast cancer (TNBC)[1] BRD4/CK2-IN-1 (compound 44e) (0-25 μM; 24 hours) has anti-proliferation effect withIC50s of 2.66 and 3.52 μM in MDA-MB-231 and MDA-MB-468 cells, respectively[1]. BRD4/CK2-IN-1 (0-10 μM; 24 hours) dose-dependently induces apoptosis of MDA-MB-231 and MDA-MB-468 cells[1]. BRD4/CK2-IN-1 (0-10 μM; 24 hours) dose-dependently downregulates Bcl-2 but upregulates Bax and cleaved caspase-3[1]. BRD4/CK2-IN-1 (0-10 μM; 24 hours) significantly downregulates the autophagy substrate p62 and up-regulated beclin-1 and LC3II in MDA-MB-231 and MDA-MB[1].

BRD4/CK2-IN-1 (25 and 50 mg/kg; intragastric administration; daily for 19 days) inhibits tumor growth in TNBC xenograft models[1]. BRD4/CK2-IN-1 (25 and 50mg/kg; intragastric administration; daily for 19 days) shows weak toxicity measured by body weight loss in the MDA-MB-231 and MDA-MB-468 xenograft models[1]. Preliminary Assessment of Pharmacokinetics (PK) profile of BRD4/CK2-IN-1[1].
