[Phytopharmacological study on proadiphene, amiphenazole and bemegride in association with phenobarbitone (author's transl)].

The capacity of 2-diethylaminoethyl-alpha, alpha-diphenylvalerate (proadiphene), 2,4-diamino-5-phenyl-thiazole (amiphenazole) and 2,6-dioxo-4-methyl-4-ethyl-piperidine (bemegride) of stimulating or stopping the growth of seedlings of Lepidium sativum L. was tested. Only bemegride shows a weak stimulating effect between 10(-3) and 10(-2) moles/l. In combination with phenobarbital these compounds counteract the stimulating effect and increase the inhibiting one of this barbiturate on the growth of the seedlings.
