S. Younes et al., SYNTHESIS AND CALCIUM ANTAGONISTIC ACTIVITY OF DIETHYL STYRYLBENZYLPHOSPHONATES, European journal of medicinal chemistry, 29(2), 1994, pp. 87-93
Twenty-three new phosphonic ester derivatives of stilbene exhibiting s
tructural analogies with fostedil are described. Examination of calciu
m antagonism showed that this activity could not be increased by intro
ducing electron-withdrawing, electron-releasing or lipophilic substitu
ents. Only compounds containing fluorine at the 2 or 4 positions exhib
ited similar activity to the model.
