Thiazolo[3,2-a]pyrimidine derivatives as calcium antagonists
Balkan,Uma,Ertan,Wiegrebe
, p. 687 - 688 (2007/10/02)
Some new thiazolo[3,2-a]pyrimidine derivatives were prepared refluxing 2-thioxo-1,2,3,4-tetrahydropyrimidine derivatives with phenacyl bromide in glacial acetic acid. Calcium antagonistic activities of these compounds were evaluated in K+-depolarized rat aorta, using nifedipine as reference compound.
