Spirocyclopropane compounds. III. Synthesis of spiro(benzofuran-2(3H),1'-cyclopropan)-3-ones for evaluation as gastric antisecretory and antiulcer agents.
抄録
Spiro [benzofuran-2 (3H), 1'-cyclopropan]-3-one (VI-1) and its derivatives (VI-2-VI-75) were synthesized in the same manner as described previously for the synthesis of spiro [cyclopropane-1, 2'-[2H] indol]-3'(1'H)-ones (I). These spiro [benzofuran-2 (3H), 1'-cyclopropan]-3-ones were evaluated for gastric antisecretory activity and protective activity against lesions induced by water-immersion restraint stress in the rat. The most potent antiulcer compounds (VI-17 and VI-55) were obtained by the introduction of an acetyl or dimethylamino group at the 5-position on the benzene ring. The most interesting member of the series, 5-acetylspiro [benzofuran-2 (3H), 1'-cyclopropan]-3-one (VI-17, AG-629), was selected as a candidate for clinical studies.
