From a search for antiulcer agents with cytoprotective activity by random screening, 1-(pyrrolidinocarbonylmethyl)-4-(2, 3, 4-trimethoxybenzyl) piperazine dimaleate (4h) was found as a lead compound. Analogues of 4h were synthesized and evaluated for antiulcer activity as well as toxicity. Four compounds (4h, p, w, x) exhibited potent antiulcer activity in several gastric ulcer models and low toxicity without any antisecretory activity. The antiulcer activity of these compounds was considered to be based on the cytoprotective activity.
通过随机筛选寻找具有细胞保护活性的抗溃疡药物的过程中,发现1-(吡咯烷甲酰甲基)-4-(2,3,4-三甲氧基苄基)哌嗪双马来酸盐(4h)是一种先导化合物。合成了4h的类似物,并评估了它们的抗溃疡活性及毒性。四种化合物(4h,p,w,x)在多个胃溃疡模型中显示出强大的抗溃疡活性,且毒性低,没有抗分泌活性。这些化合物的抗溃疡活性被认为基于其细胞保护活性。
