2-Alkoxy-4-amino-N-[(4-benzyl-2-morpholinyl)methyl]-5-chlorobenzamides had been identified as the interesting members of a series of selective and potent gastroprokinetic agents. A new series of 2-amino- and 2-(substituted amino)-N-[(4-benzyl-2-morpholinyl)methyl]benzamides (13-35) has been synthesized and these compounds were examined to determine whether they have advantages over the 2-morpholinyl benzamides 1 with a 2-alkoxy group.The gastroprokinetic activity was generally reduced, but several compounds showed relatively potent activity, comparable to that of the standard agent, metoclopramide. N-[(4-Benzyl-2-morpholinyl)methyl]-4-chloro-2-[(4-chlorobenzoyl)amino]benzamide (32) showed the most potent activity in this series.
2-烷氧基-4-氨基-N-[(4-苄基-2-吗啉基)甲基]-5-氯苯甲酰胺已被确定为一系列选择性强效胃动力药的有趣成员。我们合成了一系列新的 2-氨基-和 2-(取代氨基)-N-[(4-苄基-2-吗啉基)甲基]苯甲酰胺(13-35),并对这些化合物进行了研究,以确定它们与带有 2-烷氧基的 2-吗啉基苯甲酰胺 1 相比是否具有优势。胃动力活性普遍降低,但有几个化合物显示出相对较强的活性,可与标准药物甲氧氯普胺相媲美。N-[(4-Benzyl-2-morpholinyl)methyl]-4-chloro-2-[(4-chlorobenzoyl)amino]benzamide (32) 在该系列中显示出最强的活性。
