Novel N,N-dialkyl carboxy coumarins have been synthesized as potential anticancer agents via inhibition of monocarboxylate transporter 1 (MCT1). These coumarin carboxylic acids have been evaluated for their in vitro MCT1 inhibition, MTT cancer cell viability, bidirectional Caco-2 cell permeability, and stability in human and liver microsomes. These results indicate that one of the lead candidate compounds
通过抑制单羧酸转运蛋白 1 (MCT1),合成了新型N , N-二烷基羧基香豆素作为潜在的抗癌剂。这些香豆素羧酸的体外 MCT1 抑制、MTT 癌细胞活力、双向 Caco-2 细胞通透性以及在人类和肝微粒体中的稳定性已得到评估。这些结果表明,主要候选化合物之一4a具有良好的吸收、代谢稳定性和较低的药物流出率。在健康小鼠中对先导化合物4a进行的全身毒性研究表明,与对照组相比,该抑制剂具有良好的耐受性,动物死亡率为零,体重增加正常。小鼠体内肿瘤生长抑制研究表明,候选化合物4a在表达MCT1的GL261-luc2同种移植模型中表现出显着的单药活性,但在表达MCT4的MDA-MB-231异种移植模型中没有表现出显着的活性,表明4a的选择性对于表达 MCT1 的肿瘤。
