escape and other tumor biological functions. Pharmacological inhibition of lactate transport has been viewed as a promising therapeutic strategy to target a range of human cancers. In this study, a series of new coumarin-3-carboxylic acid derivatives 5a-t and 9a-b were synthesized and evaluated as lactate transport inhibitors. Their cytotoxic activity has been tested against three cell lines high-expressing
乳酸作为肿瘤代谢物,在肿瘤增殖、转移、血管生成、免疫逃逸等肿瘤生物学功能中起着非常重要的作用。乳酸转运的药理学抑制已被视为针对一系列人类癌症的有前途的治疗策略。在这项研究中,合成了一系列新的香豆素-3-羧酸衍生物5a - t和9a - b,并作为乳酸转运抑制剂进行了评估。它们的细胞毒活性已经针对三种细胞系高表达和低表达的单羧酸转运蛋白 1 (MCT1) 进行了测试,MCT1 作为乳酸的主要载体。化合物5c-e、5g - i和5m-o对具有高 MCT1 表达的 Hela 和 HCT116 细胞系显示出显着的细胞毒性和良好的选择性。值得注意的是,coumarin-3-hydrazide 5o是具有最强细胞毒活性的先导分子,表现出显着的抗增殖和诱导凋亡作用。进一步的研究表明,化合物5o通过显着降低葡萄糖消耗和乳酸产生来降低靶标MCT1的表达水平,并抑制Hela和HCT116细胞的能量代谢。此外,
