Novel bis[1,6-dihydro-6,6-dimethyl-1,3,5-triazine-2,4-diamines] as antitrypanosomal agents
摘要:
A series of novel 1,1'-(4,1-phenylene)bis [1,6-dihydro-6,6-dimethyl-1,3,5-triazine-2,4-diamines] was prepared and evaluated for activity against Trypanosoma rhodesiense in mice. The importance of the bis structure and the nature of the spacer between the two phenyl rings for optimal activity have been revealed. The potent parenteral activity of several analogues within this series as well as preliminary indication of oral activity lends encouragement to further development of this structural class.

Abstract Symmetrical diarylureas can be prepared by purging an aromaticamine with carbondioxide in the presence of a strong amidine base followed addition of solid commercially available Me3N.SO3. Work up is simply by dilution with water. The procedure is far simpler and safer than traditional methods using phosgene or isocyanates.
