Design and synthesis of a new series of 5,6-diarylimidazo[2,1-b]thiazole derivatives possessing terminal aryl sulfonamide moiety are described. Their in vitro antiproliferative activities against a panel of 57 human cancer cell lines of nine different cancer types were tested at the NCI. Compounds 8a, 8b, 8n, 8q, 8t, and 8u showed the highest mean % inhibition values over the 57 cell line panel at
描述和设计了一系列新的具有末端芳基磺酰胺部分的5,6-二芳基咪唑并[2,1- b ]噻唑衍生物。在NCI上测试了它们针对9种不同癌症类型的57种人类癌细胞系的体外抗增殖活性。在10μM下,化合物8a,8b,8n,8q,8t和8u在57个细胞系中显示出最高的平均%抑制值,并在5剂量测试模式下对其进行了进一步测试,以确定其IC 50值。在这六个化合物中,具有末端对位的化合物8u-羟基苯磺酰胺基部分和乙烯连接基显示出最高的效力。它对八种不同的细胞系显示出比索拉非尼更强的效力,并且对索罗非尼的对COLO 205结肠癌细胞系的功效相等。其相对于NCI-H460非小细胞肺癌细胞系和MCF7乳腺癌细胞系的IC 50值分别为0.845μM和0.476μM。化合物8a,8b,8q,8t和8u相对于L132正常肺细胞株显示出对癌细胞的高选择性指数。化合物8u对ERK途径的成分显示出潜在的抑制作用。其IC 50
