Abstract
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.
