MDH1 and MDH2 enzymes play an important role in the survival of lung cancer. In this study, a novel series of dual MDH1/2 inhibitors for lung cancer was rationally designed and synthesized, and their SAR was carefully investigated. Among the tested compounds, compound 50 containing a piperidine ring displayed an improved growth inhibition of A549 and H460 lung cancer cell lines compared with LW1497
MDH1 和 MDH2 酶在肺癌的存活中起重要作用。本研究合理设计合成了一系列新型肺癌MDH1/2双重
抑制剂,并对其
SAR进行了仔细研究。在所测试的化合物中,与 LW1497 相比,含有
哌啶环的化合物 50 显示出对 A549 和 H460 肺癌
细胞系的生长抑制有所改善。化合物50呈剂量依赖性降低A549细胞总
ATP含量;它还以剂量依赖性方式显着抑制缺氧诱导因子 1-α (HIF-1α) 的积累和 HIF-1α 靶
基因如 GLUT1 和
丙酮酸脱氢酶激酶 1 (PDK1) 的表达。此外,化合物 50 在 A549 肺癌细胞缺氧条件下抑制 HIF-1α 调节的 CD73 表达。总的来说,
