A facile construction of a thiophene ring fused with N-heterocycles has been achieved via the reaction of NaSH with 2-chloro-3-alkynyl quinoxalines/pyrazines leading to novel 2-substituted thieno[2,3-b]pyrazine/quinoxaline derivatives as potential inducers of apoptosis. Some of them showed encouraging pharmacological properties when tested in zebrafish.
通过NaSH与2-氯-3-炔基喹喔啉/吡嗪反应,可轻松合成与N-杂环稠合的噻吩环,从而生成新的2-取代的噻吩并[2,3- b ]吡嗪/喹喔啉衍生物,潜在的细胞凋亡诱导剂。其中一些在斑马鱼中测试时显示出令人鼓舞的药理特性。
