Antimalarial and insecticidal activities of newly synthesized derivatives of Benzimidazole.

The bioactive benzimidazole and corresponding substituted phenacyl halides has been synthesized (11) new derivatives out of three compounds 8, 10 and 11 were found to inhibit the Plasmodium falciparum moderately after 72 hours of incubation hence acting as antimalarial agents. While these derivatives were exhibited negligible insecticidal activity too when analyzed by impregnated filter paper method.
