ABSTRACT

A series of pyrimidine derivatives as acid pump antagonists (APAs) was synthesized and the inhibitory activities against H(+)/K(+) ATPase isolated from hog gastric mucosa were determined. After elaborating on substituents at C2 and C4 position of the pyrimidine scaffold, we have observed that the compound 7h is a potent APA with H(+)/K(+) ATPase, IC(50) = 52 nM.
