AbstractA series of 18 new 3,4-disubstituted-isothiochromeno[3,4-e][1,2]oxazines 28–45 has been obtained from the 3′,4′-di-substituted-4′H-spiro[isothiochromene-3,5′-isoxazol]-4(1H)-ones 10–27 in refluxing HCl acid/ethanol. A series of 15/18 compounds 28–45 was selected by the National Cancer Institute (NCI, Bethesda, USA) and were evaluated against a full panel of 60 primary human tumor cell lines
摘要从3',4'-二取代-4'H-螺[异硫代色素]获得了一系列18种新的3,4-二取代-异硫代色素[3,4- e ] [1,2]恶嗪28-45。 -3,5'-异恶唑] -4(1H)-在回流的盐酸/乙醇中为10–27。美国国家癌症研究所(NCI,Bethesda,USA)选择了一系列15/18化合物28–45,并针对来自60种源自9种人类癌症的原代人类肿瘤细胞系进行了全面评估,所有这些细胞系均具有抗增殖能力活性在微摩尔范围内。活性最高的化合物编号37(S722910)对所有测试的细胞系均具有很高的效价,其GI 50平均值在30–80μM的范围内。TGI和LC 50 值分别为12–16μM,分别对98%和63%的受试细胞系(Breast-MCF7和NCS-SF-268)有阳性反应。 图形概要
