2,4-Amino, guanidinopyrimidines have diuretic activity. A representative species of these compounds is 2-guanidino-4-amino-6-chloroguanidine which is prepared by the stepwise replacement of first the 2-halo of a 2,4,6-trihalopyrimidine by guanidino and then the 4-halo by ammonia.
2,4-氨基鸟嘌呤酸具有利尿活性。这些化合物的代表物种是2-鸟氨基-4-氨基-6-氯鸟嘌呤,通过逐步替换2,4,6-三卤鸟嘌呤的第一个2-卤素原子为鸟氨基,然后再将第四个卤素原子替换为氨而制备。
