Four series of 2-substituted-4-morpholino- 7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidine derivatives (9-28) were designed, synthesized and their structures were confirmed by 1H NMR, 13C NMR and MS spectrum. All compounds were evaluated for the IC50 values against three cancer cell lines (A549, PC-3 and MCF-7). And four selected compounds (10, 11, 24, 27) were further evaluated for the IC50 values against
设计,合成了4个系列的2-取代-4-吗啉代-7,8-二氢-5H-硫代吡喃并[4,3-d]嘧啶衍生物(9-28),并通过1 H NMR,13 C NMR和1H NMR证实了它们的结构。 MS质谱图。评估了所有化合物对三种癌细胞系(A549,PC-3和MCF-7)的IC50值。然后进一步评估了四种选择的化合物(10、11、24、27)针对PI3Kalpha和mTOR激酶的IC50值。七个目标化合物针对这三种癌细胞系表现出中等至出色的抗肿瘤活性。最有前途的化合物11对A549,PC-3和MCF-7细胞系显示出良好的抗肿瘤潜能,IC50值分别为0.52 +/- 0.10μM,1.41 +/- 0.10μM,4.82 +/- 0.24μM,并具有中等的抗肿瘤活性PI3Kalpha / mTOR,IC50值为6.72 +/- 0.30μM和0.94 +/- 0.10μM。结构-活性关系(SARs)和对
