chloropheny1)-4-[(a-methyl-29-diethylaminobuty1)-amino]-6-methylquinoline, was also active. The principle involved was then extended so that the simple central pyridine nucleus of atebrin was used as a fundamental gr~ uping.~ Among the compounds examined was Z- (py-diethylami-nopropylaminop1ienyl)-pyridine which was shown to be active in experimental avian malaria. A logical extension from the fuzed trinuclear system of atebrin ...
