Abstract

A series of guanylhydrazone, amidine, and hydrazone derivatives of 2-phenylimidazo [1, 2- a] pyridine have been prepared and evaluated for macrofilarial activity against Acanthocheilonema viteae and Brugia pahangi in jirds. Compounds with 4', 6-bis- substitution by cyclic guanylhydrazone groups show activity. 4', 6-Bis-amidines show some activity but are more toxic; 4'-or 6-monosubstituted compounds are inactive. 2, 6-Bis- ...
