Tetrazolo[1,5‐a]quinoline‐4‐carbaldehyde, 3‐oxo‐3‐phenylpropanenitrile, and β‐enamine were reacted in one‐pot to obtain highly functionalized quinolinyl‐1,4‐dihydropyridines. In addition to spectroscopic characterization, the structure of one of the compound is confirmed by single‐crystal X‐ray diffraction. Among all compounds evaluated for cytotoxic effect against MCF7, three quinolinyl‐1,4‐dihydropyridines (SKS13, 19, and 20) were found to be most active with half inhibition concentrations value of 7.87–9.55 μM. Molecular docking of the active molecules to various breast cancer targets revealed effective compounds have multiple receptor targeting potential in breast cancer. Our results corroborate quinolinyl‐1,4‐dihydropyridines as a valuable scaffold to develop anticancer drugs.
