  2-alkylamino-5- or 6-aralkyl-substituted benzazoles were synthesized and tested for histamine H2-receptor antagonist and anti-stress ulcer activities. These new compounds showed little or no histamine H2-receptor antagonist activity in contrast to imidazo[1,2-a]pyridine analogues (I). On antiulcer assay, however, some pyridine derivatives (II) exerted higher activity than the reference compounds, sofalcone
