Studies in Potential Filaricides: Part XI - Synthesis of 2-Dialkylaminomethyl-4-substitutedamino-phenols as Amodiaquine Analogs

A number of 4,7-disubstituted quinazolines (11-17) and 2-dialkylaminomethyl-4-acetylaminophenols (19-30) have been synthesized and tested for their antifilarial activity against Litosomoides carinii in cotton rat (Sigmodon hispidus).Of the compounds tested 19-21 and 26 cause 60percent fall in microfilarial count at a dose of 30 mg/kg given intraperitoneally daily for 6 days.None of the compounds possesses any macrofilaricidal activity.
