Synthesis and calcium antagonistic activity of diethyl styrylbenzylphosphonates
摘要:
Twenty-three new phosphonic ester derivatives of stilbene exhibiting structural analogies with fostedil are described. Examination of calcium antagonism showed that this activity could not be increased by introducing electron-withdrawing, electron-releasing or lipophilic substituents. Only compounds containing fluorine at the 2 or 4 positions exhibited similar activity to the model.
