Design, synthesis and exploration of in silico α-amylase and α-glucosidase binding studies of pyrrolidine-appended quinoline-constrained compounds


A series of new pyrrolidine-appended phenoxy-substituted quinoline derivatives were synthesized using 2-chloro-3-formyl quinoline. Initially, the second position of 2-chloro-3-formyl quinoline was successfully converted into various substituted phenoxy-substituted quinolines using various substituted phenols; then, its aldehyde function was reduced to its corresponding alcohols which is in turn converted into its corresponding pyrrolidine-appended phenoxy-substituted quinolines by treating it with 1-(2-chloroacetyl)pyrrolidine-2-carbonitrile. All these newly synthesized compounds were subjected to the in silico studies with the α-amylase and α-glucosidase enzymes to predict the binding affinity.
