A Novel Histamine 2(H2) Receptor Antagonist with Gastroprotective Activity. II. Synthesis and Pharmacological Evaluation of 2-Furfuryl-thio and 2-Furfurylsulfinyl Acetamide Derivatives with Heteroaromatic Rings.
recently found that N-[3-[3-(piperidinomethyl)phenoxyl]propyl]acetamide derivatives with a thioether function showed gastricanti-secretory and gastroprotective activities and that the thioether function (particularly furfurylthio or furfurylsulfinyl) was essential for gastroprotection. In the present study, a series of 2-furfurylthio and 2-furfurylsulfinyl acetamide derivatives were synthesized and
