title: Uterine stimulant action of some omega-chain modified (+)-11-deoxyprostaglandins.
abstract: Rat uterine stimulant activity has been determined in vivo for a series of (+)-11-deoxyprostaglandins. The most active members of the series. 11-deoxy-15 methyl-PGE1, 11-deoxy-16,16-dimethyl - PGE1 and its 1-alcohol were 2-3 times more potent than PGE1. Gastrointestinal side effects assessed by the antagonism of morphine-induced constipation in the mouse, were generally relatively low with these compounds and consequently several members of the series had a more favourable relative selectivity than 16,16-dimethyl-PGE2 methyl ester.
