Abstract Many shreds of evidence have recently correlated A2B receptor antagonism with anticancer activity. Hence, the search for an efficient A2B antagonist may help in the development of a new chemotherapeutic agent. In this article, 23 new derivatives of [1,2,4]triazolo[4,3-a]quinoxaline were designed and synthesized and its structures were confirmed by different spectral data and elemental analyses
摘要 最近有许多证据表明 A2B 受体拮抗作用与抗癌活性有关。因此,寻找有效的 A2B 拮抗剂可能有助于开发新的化疗药物。本文设计合成了23种新的[1,2,4]三唑并[4,3- a ]喹喔啉衍生物,并通过不同的光谱数据和元素分析证实了其结构。这些化合物的细胞毒性评估结果显示六种有希望的活性衍生物,IC 50MDA-MB 231 细胞系上的值范围为 1.9 到 6.4 μM。此外,对所有合成化合物进行分子对接以预测它们对 A2B 受体同源模型的结合亲和力,作为其细胞毒活性的建议模式。分子对接的结果与细胞毒性研究的结果密切相关。最后,探索了新化合物的构效关系分析。 图形摘要
