The synthesis and filaricidal activity of l-iso-butoxycarbonyl-4-mcthylpipcrazinc against Litomosoides carinii in Sigmodon hispidus and Dipctaloncma viteae in Mastomys natalcnsis is reported. At an intrapcritoncal or oral dose of 3 mg/kg given for 6 days, the compound removed 91% of the circulating microfilariac but had no effect on adult L carinii. However, it killed all microfilariae and adults of D. viteae at a subcutaneous dose of 50 mg/kg given for 6 days. The compound also possessed ehemoprophylaetic activity against the larvae of L. carinii and D. viteae at a dose of 30 and 50 mg/kg respectively.
