5-Acetylspiro [benzofuran-2 (3H), 1'-cyclopropan]-3-one (1a) shows potent gastric antisecretory and antiulcer activities in rats. In an attempt to improve the pharmacological profile of 1a, we synthesized positional isomers, as well as the prenyloxy and oxime derivatives. Evaluation of their antisecretory activities and protective activities against gastric lesions induced by water-immersion restraint stress in the rat indicated that the 7-acetyl derivative (1d) was equipotent to 1a.
5-乙酰基螺[苯并呋喃-2(3H),1'-环丙烷]-3-酮(1a)在大鼠中显示出强大的胃抗分泌和抗溃疡活性。为了改善1a的药理学特性,我们合成了位置异构体以及 prenyl 氧基和肟衍生物。评估它们抗分泌活性以及对大鼠水浸束缚应激诱导的胃损伤的保护作用表明,7-乙酰衍生物(1d)与1a等效。
