Synthesis and pharmacological properties of N-[3-(3-(1-Piperidinylmethyl)phenoxy)propyl]-2-(2-hydroxyethylthio)- acetamide and related compounds as antiulcer agents. I.

N-Phenoxypropylacetamide derivatives were prepared and tested for antiulcer activity. These compounds exhibited both gastric acid antisecretory and cytoprotective properties. Structure-activity studies led to the identification of N-[3-(3-(1-piperidinylmethyl)phenoxy)propyl]-2-(2-hydroxyethylt hio)acetamide (8), which was selected for further development and clinical evaluation.
