ABSTRACT
We report the preliminary in vitro characterization of a series of pyrimidines as a new chemotype that modulates cardiovascular parameters and relaxes ileum smooth muscle according to classical calcium entry blockers. Tested compounds showed an interesting negative inotropic selectivity. In patch-clamp experiments they block L- over T-type calcium currents. Two requisites seem essential for the activity lipophilic substituents in positions 2 and 5 of the pyrimidine ring and the acetamidic function in position 6.
