  Novel N-(benzo[d]thiazol-2-ylcarbamoyl)-2-methyl-4-oxoquinazoline-3(4H)-carbothioamide derivatives were synthesized and evaluation of their anticonvulsant effects was done using various models of experimental epilepsy. Initial anticonvulsant activities of the compounds were investigated using intraperitoneal (i.p.) maximal electroshock shock (MES), subcutaneous pentylenetetrazole (scPTZ) seizure models

  日期：2000.5

  The 1H and 13C NMR spectra of twelve 4H-3,1-benzoxazine-4-ones and of their acylaminobenzoic acid precursors are presented. Differentiation between these two series of compounds is best achieved through the characteristic J(CH) coupling interactions in the high frequency carbonyl region. Some 4H-pyrido[2,3-d][1,3]oxazin-4-ones have also been studied and some earlier literature assignments revised.

  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。
