important therapeutic targets such as the isocitrate dehydrogenase 2 (IDH2). A series of macrocyclic derivatives was designed based on the marketed IDH2 inhibitor AG-221 by using the conformational restriction strategy. The resulted compounds showed moderate to good inhibitory potential against different IDH2-mutant enzymes. Amongst, compound C6 exhibited better IDH2R140Q inhibitory potency than AG-221,
参与癌细胞代谢途径的酶已被证明是重要的治疗靶点,例如
异柠檬酸脱氢酶 2 (IDH2)。基于已上市的IDH2
抑制剂AG-221,采用构象限制策略设计了一系列大环衍
生物。所得化合物对不同的 IDH2 突变酶显示出中等至良好的抑制潜力。其中,化合物C6表现出比AG-221更好的IDH2 R140Q抑制效力,并在体外表现出优异的2-羟基
戊二酸(2-
HG)抑制活性,其
甲磺酸盐表现出良好的药代动力学特征。此外,C6对 IDH2 具有强结合模式R140Q经过计算对接和动态仿真,可作为进一步发展的良好起点。
