Library of diversely substituted 2-(quinolin-4-yl)imidazolines delivers novel non-cytotoxic antitubercular leads.

A novel library based on quinolin-4-ylimidazoline core was designed to incorporate a general quinoline antimicrobial pharmacophore. A synthesis of the well-characterized library of 36 compounds was achieved using the Pd-catalyzed Buchwald-Hartwig-type imidazoline arylation chemistry developed earlier. Compounds were tested for biological activity and were found to possess no antimalarial activity.
