A new series of 4,5-dihydro-1H-thiochromeno[4,3-d]pyrimidine derivatives have been designed and synthesized. The antitumor activities of the target compounds have been evaluated in vitro against two human cancer cell lines including A549 (human alveolar adenocarcinoma cell) and H460 (human lung cancer) by MTT assay. Most of the target compounds exhibited significant antitumor activities against A549 and H460 cancer cell lines. The most potent compound 4-(benzo[d][1,3]dioxol-5-yl)-8,9-difluoro-2-(4-methylpiperazin-1-yl)-4,5-dihydro-1H-thiochromeno[4,3-d]pyrimidine (CH05) (IC50 = 0.44 μM, 3.07 μM) was 2.0 and 8.4 times more active than gefitinib (IC50 = 0.89 μM, 16.81 μM) against A549 and H460 cell lines, respectively.
设计并合成了一系列4,5-二氢-1H-硫杂色满并[4,3-d]嘧啶衍生物。通过MTT法,在体外对两种人癌细胞系(包括A549(人肺泡腺癌细胞)和H460(人肺癌细胞))进行了目标化合物的抗肿瘤活性评估。大多数目标化合物对A549和H460癌细胞系表现出显著的抗肿瘤活性。其中最强效的化合物4-(苯并[d][1,3]二氧戊环-5-基)-8,9-二氟-2-(4-甲基哌嗪-1-基)-4,5-二氢-1H-硫杂色满并[4,3-d]嘧啶(CH05)(IC50 = 0.44 μM,3.07 μM)对A549和H460细胞系的活性分别是吉非替尼(IC50 = 0.89 μM,16.81 μM)的2.0倍和8.4倍。
