通过适当的硫代半脲酮衍生物与双-2-溴代乙酰基噻吩并[2,3- b ]噻吩衍生物在乙醇中回流下的反应,已经开发出一种新颖,简便的合成双噻唑衍生物系列的方法。新合成产物的结构是根据光谱数据(质量,IR和1 H和131 H NMR)和元素分析。评价了合成化合物中的十五种化合物对人肝肝癌细胞系(HepG2)的抗癌活性。所有化合物均显示出抗癌活性,但效力与参考药物顺铂相当。此外,使用MOE软件进行的分子对接研究预测了活性最高的化合物5o与人类热休克蛋白90的活性位点之间的最佳结合方式。计算研究证实了生物学活性的结果。
Novel 2-thiazolylphthalazine derivatives were efficiently synthesized underultrasoundirradiation, resulting in high yields and short reaction times after optimization of the reaction conditions. All prepared compounds were fully characterized using spectroscopic methods. They were screened for their antimicrobial activity against Gram-positive and Gram-negative bacteria as well as for antifungal
