4-Aryl-3, 4-dihydropyrimidin-2 (1H)-ones (Biginelli compounds, DHPMs) represent an azaheterocyclic system of remarkable pharmacological profile [1]. It was investigated during 1980s and 1990s that DHPMs exhibit a similar pharmacological profile to the Hantzsch's 1, 4- dihydropyridine calcium channel modulators of the nifedipine type drugs [2]. In particular, the 2-heterosubstituted 4-aryl-1, 4-dihydro-6-methyl-5-pyrimidinecarboxylic acid esters were ...
