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.
