Objective: This study focuses on the design, synthesis, and antitumor evaluation of phenyl ureas bearing 5-fluoroindolin-2-one moiety. Methods: Three sets of phenylureas were designed and synthesized and their antiproliferative ability was measured against four human carcinoma cell lines (Hela, Eca-109, A549, and MCF-7) via MTT assay. In vivo anticancer activity was further evaluated in xenograft models
背景:新型抗肿瘤药的开发仍然非常需要。 目的:本研究的重点是带有5-氟吲哚-2-酮部分的苯基脲的设计,合成和抗肿瘤评估。 方法:设计并合成了三套苯基脲,并通过MTT法测定了它们对四种人类癌细胞系(Hela,Eca-109,A549和MCF-7)的抗增殖能力。在人乳腺癌的异种移植模型(MCF-7)中进一步评估了体内抗癌活性。 结果:总共合成了二十一种新化合物,并通过1H和13C NMR以及HR-MS进行了表征。最初构建了三组化合物(1a‒1c,2a‒2c和3a‒3c),并评估了这些分子对Hela,Eca-109,A549和MCF-7的初步抗增殖活性,突出了间位取代的苯基脲(1a‒1c)是最具细胞毒性的药物。然后设计并合成了一系列间位取代的苯基脲衍生物(1d‒1o)用于结构-活性关系研究。大多数新化合物显示出理想的细胞毒性,其中化合物1g对测试的人类癌细胞表现出最显着的细胞毒性作用,IC50值为1
