Abstract
We have developed a convenient one-pot multicomponent synthesis of highly functionalized [1,6]-naphthyridines under solvent free condition using [Et3NH][HSO4] in excellent yield. This protocol offers several advantages, including short reaction time, simple experimental workup procedure and no toxic byproducts, avoids the use of toxic organic solvents and anhydrous conditions. Further. we have screened the synthesized naphthyridines for in vitro antibacterial, antifungal and antioxidant activity. Furthermore, a molecular docking study of these compounds was carried out to investigate their binding pattern with the target, β-Ketoacyl-acyl carrier protein synthase III (FabH). Finally, the ADME parameters for these compounds showed good drug like properties and can be developed as oral drug candidates.
