  Due to increased lactate production during glucose metabolism, tumor cells heavily rely on efficient lactate transport to avoid intracellular lactate accumulation and acidification. Monocarboxylate transporter 4 (MCT4/SLC16A3) is a lactate transporter that plays a central role in tumor pH modulation. The discovery and optimization of a novel class of MCT4 inhibitors (hit 9a), identified by a cellular

  由于葡萄糖代谢过程中乳酸产生增加，肿瘤细胞严重依赖有效的乳酸转运来避免细胞内乳酸积累和酸化。单羧酸转运蛋白 4 (MCT4/SLC16A3) 是一种乳酸转运蛋白，在肿瘤 pH 调节中发挥核心作用。描述了通过 MDA-MB-231 细胞筛选鉴定的一类新型 MCT4 抑制剂（命中9a ）的发现和优化。在溶解 GFP 标记的转运蛋白后，通过荧光互相关光谱和显微镜研究显示了优化化合物18n与 MCT4 胞质结构域的直接靶相互作用。体外用18n处理可抑制 MCT4 高表达细胞的乳酸外流并降低细胞活力。此外， 18n的药代动力学特性允许在小鼠肿瘤模型中评估乳酸调节和抗肿瘤活性。因此， 18n是研究选择性 MCT4 抑制及其对肿瘤生物学影响的宝贵工具。
