Abstract
The synthesis and cardiac activity of four 3,4-dihydropyrimidin-2-one-5 carboxylates are reported. We synthesized 3,4-Dihydropyrimidinones (DHPMs) by Biginelli reaction using classic and microwave methods and the yield of these methods compared with each other. Then cardiotonic activity of four derivatives of DHPMs was investigated on isolated perfused right atria. Compound 2b had significant chronotropic effect in comparison to negative control at concentration of 0.01M.
