Design, synthesis and antitumor activity of steroidal pyridine derivatives based on molecular docking

With steroid as a carrier nucleus and introducing a pyridine heterocycle as a pharmacophore on the D ring, a series of steroidal pyridine derivatives were designed and studied for their antitumor activity by molecular docking software. The compounds were synthesized as small molecule inhibitors and studied as anticancer agents. The synthesis of the analogs was performed in a one-pot multi-component reaction and the corresponding compounds were screened in vitro for their antitumor activity. Four adherently growing cancer cell lines were used and arranged before dosing. Among all compounds screened for their antitumor activity, compounds 2f and 2p were found to be the most active. Here, the most obvious changes in the morphology of the treated cells could be observed.
