for the synthesis of 3-methyl-5-phenylethynyl[1,2,4]triazine (4), 6-methyl-3-phenylethynyl[1,2,4]triazine (5), and 5-methyl-3-phenylethynyl[1,2,4]triazine (6a) as analogues of 2-methyl-6-(phenylethynyl)pyridine (2). The compounds were evaluated for antagonism of glutamate-mediated mobilization of internal calcium in an mGluR5 in vitro efficacy assay. The most potent of the three analogues was 6a. Twenty
开发了用于合成3-甲基-5-苯基乙炔基[1,2,4]三嗪(4),6-甲基-3-苯基乙炔基[1,2,4]三嗪(5)和5-甲基- 3-苯基乙炔基[1,2,4]三嗪(6a)是2-甲基-6-(苯基乙炔基)吡啶(2)的类似物。在mGluR5体外功效测定中,评估了化合物对谷氨酸介导的内部钙动员的拮抗作用。三种类似物中最有效的是6a。合成了另外20种6a类似物,并评估了mGluR5拮抗剂的功效。最有效的化合物是3-(3-甲基苯基乙炔基)-5-甲基[1,2,4]三嗪(6b),5-(3-氯苯基乙炔基)-5-甲基[1,2,4]三嗪(6c) ,和3-(3-溴苯基乙炔基)-5-甲基[1,2,4]三嗪(6d)。
