摘要
目的设计并制备了11个新型2-(4-喹啉/喹唑)啉硫代-6-氨基苯并噻唑类化合物,并探讨其抗肿瘤活性。方法依据拼合原理,将2-巯基-6-氨基苯并噻唑和4-氯-6,7-二甲氧基喹唑啉(或喹啉)两个片段结合,形成关键结构并据此合成系列衍生物,用MTT法进行体外抗肿瘤活性评价和构效关系研究。结果与结论合成的11个新化合物Ia^Ik未见文献报道;其中化合物Ic对黑色素瘤细胞株A2058的IC50为21.2μmol·L-1(Sorafenib 23.5μmol·L-1);化合物Ib、Ic对黑色素瘤细胞株A875的IC50分别为25.4、27.0μmol·L-1(Sorafenib 28.5μmol·L-1),显示的活性均优于阳性对照药物,但对测试的其他肿瘤细胞株均未显示活性。
OBJECTIVE To synthesize eleven 2 - (6,7 - dimethoxyquinolin - 4 - ykhio) benzol d] thiazol - 6 - amine derivatives, and evaluate their anticancer activities. METHODS According to combination principles, the target compounds were synthesized from the reactions of 6 - aminobenzo [ d ] thiazole - 2 - thiol and 4 - chloro - 6,7 - dimethoxyquinoline ( quinazoline ) , followed by different acyl chloride. The preliminary anticancer activity was tested by the MTT assay. RESULTS and CONCLUSION Eleven novel target compounds I a - I k were synthesized. Among these compounds, ICso value of compound Ic was 21.2 μmol·L-1 (Sorafenib was 23.5 μmol·L-1 ) against A2058; ICs~ values of compound Ib, Ic were 25.4,27.0 μmol·L-1 (Sorafenib was 28.5 μmol·L-1 ) against A875, respectively. The evaluation in vitro showed they had higher anti - tumor activity against melanoma cell than Sorafenib as positive control. However,they exhibited no activity against the other cell lines which have been tested.
