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.

threat to public health. To develop a broad-spectrum inhibitor of influenza to combat the problem of drug resistance, we previously identified the highly conserved E339...R416 salt bridge of the nucleoprotein trimer as a target and compound 1 as an inhibitor disrupting the salt bridge with an EC50 = 2.7 μM against influenza A (A/WSN/1933). We have further modified this compound via a structure-based
