A series of novel 6-substituted imidazo[1,2-a]pyrazines were synthesized via palladium catalyzed amino- or alkoxycarbonylation as key step. The anti-secretory activity of these compounds has been assessed in a binding assay against H(+)/K(+)-ATPase from hog gastric mucosa. Some of the compounds proved to be potent inhibitors of the gastric acid pump.
The Invention relates to 6-substituted imidazopyrazines of formula 1, in which the substituents and symbols have the meanings Indicated in the description. The compounds have gastric secretion inhibiting and excellent gastric and intestinal protective action properties.
