Synthesis and anti-staphylococcal activity of a number of substituted 2-anilinobenzimidazoles, benzothiazoles and benzoxazoles are reported. The anti-staphylococcal activities were evaluated in standard in vitro MIC assay method. While anilinobenzimidazole derivatives 11-45 showed very potent anti-staphylococcal activities (greatest activity with an MIC value of 0.095 mu g/mL), none of the 2-anilinobenzothiazoles and benzoxazole derivatives exhibited inhibitory activity. QSAR analysis of the anilinobenzimidazoles was studied on the relationship between the anti-staphylococcal activity (MIC in mu g/ml) and extrapolated log k(w) values. (c) 2007 Elsevier Masson SAS.

Synthesis and potent antiprotozoal activity of mono/di amidino 2-anilinobenzimidazoles versus Plasmodium falciparum and Trypanosoma brucei rhodesiense
antiparasitic activity against Plasmodium falciparum (P. falciparum) and Trypanosomabruceirhodesiense (T.b. rhodesiense) were evaluated in vitro. Some of the dicationic compounds (10,12,14) showed equal or very close activity against T.b. rhodesiense with melarsoprol and also showed promising activity against P. falciparum as compared to chloroquine. Among the monocationic derivatives compound 21 exhibited
