Numerous analogues of N-phenethyl-2-(isochroman-1-yl)-1-methylethylamine (3b), previously found to have inhibitory activity against aspirin-induced ulcer and no gastric antisecretory activity, were prepared and examined for gastric antisecretory activity and inhibitory activity against aspirin-induced ulcers in rats. It was found that a basic amine moiety is required for the antiulcer activity. Replacement of the isochroman ring of 3b by a thioisochroman, chroman, or tetralin ring resulted in a drastic change in the antiulcer activity. Among them, the chroman analogue N-phenethyl-2-(chroman-4-yl)-1-methylethylamine (32b) was found to have the most potent antiulcer activity, comparable with that of 3b.
我们准备了多种N-苯乙基-2-(异香豆烷-1-基)-1-甲基乙胺(3b)的类似物,之前发现其对阿司匹林诱导的溃疡具有抑制活性,并且没有胃抗分泌活性。我们对这些类似物进行了胃抗分泌活性和对阿司匹林诱导溃疡的抑制活性检测。研究发现,抗溃疡活性需要一个碱性胺基团。将3b的异香豆烷环替换为硫异香豆烷、香豆烷或四氢萘环,导致抗溃疡活性的显著变化。在这些类似物中,香豆烷类似物N-苯乙基-2-(香豆烷-4-基)-1-甲基乙胺(32b)显示出最强的抗溃疡活性,效果与3b相当。
