Abstract: Sedative effects of diphenylimidazolidine derivs. (I) of the type, NR.C(:O).CPh₂.NR'2.C:O(S), were studied on rats by using a new very exact method, permitting a large mobility record on a very large no. of exptl. animals. The analgesic effects by elec. irritations and the anticonvulsive effects were also tested. For therapeutic use the best was 2-thio-5-oxo-4,4-diphenylimidazolidine (II), which was almost nontoxic, without hypnotic effect, and in analgesic effects comparable with aminopyrine. I did not increase fatigue as phenylethylbarbituric acid, but if I were used in larger amts. the agility of animals was increased. From the galenic standpoint II can be mixed with amidopyrine, phenacetin, and caffeine.
