- Y08060: A Selective BET Inhibitor for Treatment of Prostate Cancer
-
Prostate cancer is a commonly diagnosed cancer and a leading cause of cancer-related deaths. The bromodomain and extra terminal domain (BET) family proteins have emerged as potential therapeutic targets for the treatment of castration-resistant prostate cancer. A series of 2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one derivatives were designed and synthesized as selective bromodomain containing protein 4 (BRD4) inhibitors. The compounds potently inhibit BRD4(1) with nanomolar IC50 values and exhibit high selectivity over most non-BET subfamily members. One of the representative compounds 36 (Y08060) effectively suppresses cell growth, colony formation, and expression of androgen receptor (AR), AR regulated genes, and MYC in prostate cancer cell lines. In in vivo studies, 36 demonstrates a good PK profile with high oral bioavailability (61.54%) and is a promising lead compound for further prostate cancer drug development.

- Synthesis and biological evaluation of N-(3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazin-7-yl)benzenesulfonamide derivatives as new BET bromodomain inhibitors for anti-hematologic malignancies activities
-
The bromodomain and extra-terminal proteins (BETs), in particular BRD4, has been reported to play important roles in cancer, inflammation, obesity, cardiovascular disease, and neurological disorders. In this paper, a series of benzomorpholinone derivatives were synthesized and biologically evaluated as BETs inhibitors. Detailed structure–activity relationship studies led to the discovery of several new potent compounds, of which 15h and 15i displayed IC 50 values of 2.8 and 4.5 μ M against BRD4 (D1), respectively, and showed good anti-proliferation activities against four hematologic malignancies cell lines at low-micromolar concentrations, including MV4-11, OCI-LY10, Pfeifer, and Su-DHL-6 cells. This chemotype could be further optimized with respect to its potency and drug-like properties in the future.
