A novel series of 2-acetamido and 2 or 3-propanamido derivatives of 4- or 5-substituted-thiazoles was designed and synthesized. Structure elucidation of the new synthesized compounds was attained by the use of 1H & 13C NMR, and Mass spectrometry. Compounds were subjected to NCI in vitro assessment for their antitumor activity, at a single dose of 10 μM of test compounds. Compounds bearing straight
设计并合成了一系列新的2-乙酰氨基和4-或5-取代的噻唑的2-或3-丙酰胺基衍生物。通过使用1 H和13 C NMR和质谱分析,可以阐明新合成的化合物的结构。以单剂量10μM的测试化合物对化合物的抗肿瘤活性进行NCI体外评估。具有直链取代基或4-苯基功能的化合物被证明比其支链或4-甲基同类物更具活性。化合物37,41和42显示出广谱抗肿瘤活性。化合物23和27被证明具有致命性,而化合物18,21,32和37显示出75.5,69.3,96.2和92.7%至白血病CCRF-CEM细胞系显着的GI值。
