The synthesis and pharmacological profile of a series of hybrid compounds bearing the dihydropyrimidine moiety and substituted phenylthioureas joined via typical b-blocker aryloxypropanolamine group are described. Seven out of 10 new compounds tested proved to be endowed with negative inotropic and chronotropic effect as compared to Adrenaline on isolated perfused frog heart. Also ECG studies that were carried out on normotensive male rats showed that the most of the compounds exhibited significant reduction in Rmax value in the first 30 min although maintaining little change in heart rate, with hypotensive effect lasting for 1 h.We concluded that the most of the synthesized novel compounds exhibited hypotensive as well as antihypertensive effects which could be attributed to blockade of Ca2+ entry and β-adrenoreceptor blocking activities due to introduction of aryloxypropanolamine linked to N-1 substituted dihydropyrimidine moiety. Brady cardiac effects of compounds 5a-5d, 6c-6e resulting from Ca2+entry and β-adrenoreceptor blocking attenuate the sympathetic activation-associated reflex tachycardia in the heart. We selected compound 5c as a promising lead for further detailed pharmacological and preclinical evaluation studies. Springer Science+Business Media, LLC 2010.
