腺苷是肿瘤微环境中的一种免疫抑制因子,主要通过激活 A 2A腺苷受体 (A 2A R),这是一种被肿瘤劫持以逃避免疫监视的机制。小分子 A 2A R 拮抗剂正在临床试验中作为免疫治疗剂进行评估,但其作为独立疗法的疗效有限。为了增强 A 2A R 拮抗剂的抗肿瘤作用,基于 A 2A R的共晶结构,设计并合成了具有 A 2A R 拮抗作用和组蛋白去乙酰化酶 (HDAC) 抑制作用的双效化合物。 化合物24e (IHCH-3064) ) 表现出与 A 2A的有效结合R ( K i = 2.2 nM) 和对 HDAC1 的选择性抑制 (IC 50 = 80.2 nM),在体外对肿瘤细胞系具有良好的抗增殖活性。24e (60 mg/kg,bid)腹腔内给药抑制小鼠MC38肿瘤生长,肿瘤生长抑制率为95.3%。这些结果表明,靶向 A 2A R 和 HDAC 的双效化合物是潜在的免疫治疗药物,值得进一步探索。
