A series of 5-alkoxy derivatives of 3,4-dichloro-5-hydroxyfuran-2-(5H)-one (mucochloric acid, MCA) were obtained and subsequently subjected to modification in the C-4 position of 2(5H)-furanone ring. The cytotoxicity of newly synthesized compounds was evaluated in MTT assay against non-small cell lung cancer (A549) and healthy lung epithelial cell line (BEAS-2B). The derivatives containing a branched
获得了一系列3,4-二氯-5-羟基呋喃-2-(5 H)-一的5-烷氧基衍生物(粘氯酸,MCA),随后在2(5 H)-呋喃酮环。在MTT分析中评估了新合成化合物对非小细胞肺癌(A549)和健康肺上皮细胞系(BEAS-2B)的细胞毒性。在C-5位上含有支链烷氧基取代基的衍生物显示出最高的抗癌特性,而对2(5 H)-呋喃酮环的C-4位上的化合物进行修饰只会稍微改善其抗增殖特性。化合物12和15表现出对A549细胞的最佳选择性,并且还在一组不同来源的癌细胞系中进行了评估。进一步的研究表明,用化合物12和15处理A549细胞系会导致G2期细胞周期停滞并诱导caspase依赖性细胞死亡。此外,发现化合物12与厄洛替尼协同作用。
