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.
