title: Synthesis of potential antifilarial agents. 1-(5-Benzoylbenzimidazol-2-yl)-3-alkyl- and -arylureas.
abstract: A series of 1-(5-benzoylbenzimidazol-2-yl)-3-substituted ureas have been synthesized by reacting an appropriate isocyanate with 2-amino-5-benzoylbenzimidazole or by reacting methyl (5-benzoylbenzimidazol-2-yl)carbamate with various amines. Several of the compounds have demonstrated antifilarial activity against Brugia pahangi and Litomosoides carinii.
