1-Benzazepine derivatives acting as ATP-dependent potassium-channels antagonists
摘要:
In order to select between various pharmacological activities related to the 1-benzazepine nucleus, a set of 1-benzazepine derivatives bearing different N-1 or C-2 substituents were synthesized and tested in vitro as ATP-dependent Kf-channel antagonists on isolated guinea-pig trachea. Cumulative concentration curves to cromakalim were constructed in the absence or presence of the various compounds tested in comparison with glibenclamide. Products bearing N-1 substituents, especially (2-imidazolinyl)methyl showed a non-competitive antagonism towards ATP-dependent K+ channels.
通过氢化物转移至亚胺离子来氧化2,3-和2,5-二氢-1 H -1-苯并ze庚因:3 H -1-苯并ze庚因的合成
摘要:
通过将包括氢化物2转移到由杂环烯胺和BF 3生成的亚胺离子的氢化物2-2,3,5-二氢-1 H -1-苯并ze庚因的脱氢反应制备了一些3 H -1-苯并ze庚因。与2,5-二氢ħ -1-苯并吖庚因的5初步形成ħ观察-1-苯并吖庚因,在BF的存在下,其处理3导致3 ħ -1-苯并吖庚因。可以使用t-BuOK执行相同的重排。使用氘标记的底物证明了氢化物转移。叔二氢-1-苯并ze庚因也被氧化,但经过重排后变成萘胺衍生物。
