3,5-diphenyl-1H-1,2,4-triazoles with contragestational activity of the following formula ##STR1## wherein R may be located on one or the other of the two adjacent nitrogen atoms and may represent hydrogen or a group R.sub.5 CO-- wherein R.sub.5 is an aliphatic saturated or unsaturated hydrocarbyl containing from 1 to 20 carbon atoms, R.sub.1, R.sub.2 and R.sub.3, each independently are selected from hydrogen, lower alkyl and lower alkoxy or R.sub.2 and R.sub.3 together may represent a methylenedioxy group, and R.sub.4 is an aliphatic saturated or unsaturated hydrocarbyl group of from 1 to 20 carbons, with the proviso that when R is hydrogen or an R.sub.5 CO-- group wherein R.sub.5 contains 4 or less carbon atoms, R.sub.4 must contain 5 or more carbons. These compounds have proven to be highly effective in terminating pregnancy in several animal species after a single parenteral injection.
3,5-二苯基-1H-1,2,4-三唑具有以下结构的抗孕活性,其中R可能位于两个相邻氮原子中的一个,可以代表氢或一个R.sub.5 CO--基团,其中R.sub.5是含有1至20个碳原子的脂肪饱和或不饱和烃基,R.sub.1、R.sub.2和R.sub.3,每个独立地选择自氢、较低的烷基和较低的烷氧基,或者R.sub.2和R.sub.3可以共同代表一个亚甲二氧基基团,R.sub.4是含有1至20个碳原子的脂肪饱和或不饱和烃基团,但当R为氢或一个含有4个或更少碳原子的R.sub.5 CO--基团时,R.sub.4必须含有5个或更多碳原子。这些化合物已被证明在多种动物物种中通过单次肌肉注射高效地终止妊娠。
