title: Structure-Activity studies for a novel series of tricyclic dihydropyrimidines as K(ATP) channel openers (KCOs).
abstract: A novel series of tricyclic dihydropyrimidines was synthesized and evaluated for activity as K(ATP) channel openers. The functional activity of several compounds, for example 6A (EC(50)=30nM) and its enantiomers exceeded cromakalim.
