A chemical database of 30 representative imidazo-azines was built and screened against important tropical disease targets by computational docking. After three rounds of screening, an interaction profile was generated and analyzed. On the basis of binding energy and ligand efficiency, it was concluded that in general, imidazo-azine scaffold has a potential of being selective and simultaneous inhibitor against the five receptors Pf-dihydrofolate reductase, Pf-enoyl acyl carrier protein reductase, Pf-protein kinase 7, Mt-pantothenate synthetase and Mt-thymidine monophosphate kinase. Interestingly, two compounds 2-(4-chlorophenyl)-N-cyclohexyl-6-methylH-imidazo[1,2-a]pyridine-3-amine (MCL011) and N-cyclohexyl-2-(4-methoxyphenyl)-6-methylH-imidazo[1,2-a]pyridine-3-amine (MCL017) showed highest binding energy against four targets namely Pf-dihydrofolate reductase, Pf-enoyl acyl carrier protein reductase, Pf-protein kinase 7 and Mt-pantothenate synthetase. Eventually, in order to improve the decision making and success rate in actual efficacy evaluations other criteria such as lead-likeness were envisaged. (C) 2014 Elsevier Inc. All rights reserved.
