Substituted 1,4-dihydropyridines were discovered as a novel and potent series of phosphodiesterase 4 (PDE4) inhibitors. Structure-activity relationships within this series have been carried out and studies revealed that the dihydropyridine core, with indole moiety and 3,4-dimethoxybenzyl group, is a potent analogue for PDE4 inhibition. These novel series of compounds were prepared via a 3-component reaction in a single pot. In vitro biological activity, modeling studies and crystallography data are also reported.

Multicomponent Reactions for Diverse Synthesis of<i>N</i>-Substituted and NH 1,4-Dihydropyridines
The multicomponentreactions of aldehydes, electron deficient alkynes and amines have been successfully performed to yield a number of symmetrical 2,6‐unsubstituted 1,4‐dihydropyridines (1,4‐DHPs). This method has been found generally applicable for the synthesis of both N‐substituted and N‐unsubstituted 1,4‐DHPs by employing secondary amine to activate the alkyne component via enaminoester intermediates
