Synthesis and in vitro anti-proliferative effects of 3-(hetero)aryl substituted 3-[(prop-2-ynyloxy)(thiophen-2-yl)methyl]pyridine derivatives on various cancer cell lines.

A series of 3-(hetero)aryl substituted 3-[(prop-2-ynyloxy)(thiophen-2-yl)methyl]pyridine derivatives were designed as potential anticancer agents. These compounds were conveniently prepared by using Pd/C-Cu mediated Sonogashira type coupling as a key step. Many of these compounds were found to be promising when tested for their in vitro anti-proliferative properties against six cancer cell lines.
