Disclosed are compounds of Formula (I) or a salt thereof, wherein: R1, R2, R3, R4, R5, R6, and m are defined herein. Also disclosed are methods of using such compounds to inhibit the activity of one or both of diacylglycerol kinase alpha (DGKα ) and diacylglycerol kinase zeta (DGKξ ), and pharmaceutical compositions comprising such compounds. These compounds are useful in the treatment of viral infections and proliferative disorders, such as cancer.
DGKα and ζ inhibitors notwithstanding the modest similarity between α and ζ relative to other DGK isoforms. Optimized compounds produced cytokine release and T-cell proliferation consistent with DGK inhibition and potentiated an immune response in human and mouse T-cells. Additionally, lead inhibitor BMS-502 demonstrated dose-dependent immune stimulation in the mouse OT-1 model, setting the stage for a
我们描述了一种表型筛选和优化策略,以发现阻断 T 细胞内检查点信号传导的化合物。尽管 α 和 ζ 相对于其他 DGK 同工型之间有一定的相似性,但我们还是鉴定出了 DGKα 和 ζ 双重抑制剂。优化的化合物产生与 DGK 抑制一致的细胞因子释放和 T 细胞增殖,并增强人和小鼠 T 细胞的免疫反应。此外,先导抑制剂BMS-502在小鼠 OT-1 模型中证明了剂量依赖性免疫刺激,为药物发现计划奠定了基础。
