Novel indanyl-substituted imidazo[1,2-a]pyridines as potent reversible inhibitors of the gastric H+/K+-ATPase

A series of novel 8-indanylamino- and 8-indanyloxy-substituted imidazo[1,2-a]pyridines with reduced lipophilicity was synthesized from easily accessible starting compounds. The anti-secretory activity of these compounds has been assessed in a competitive binding assay against H+/K+-ATPase from hog gastric mucosa. Some of the compounds proved to be potent inhibitors of the gastric acid pump.
