Search for new Ca++ antagonists. Lipophilic oximes and phosphonates.
On the basis of the reported slow channel-inhibiting activity of oximes and phosphonates a series of compounds bearing such functions on lipophilic carriers were synthesized and studied. Among the compounds studied only (VI b) shows a slight cardiovascular activity. The surprising lack of activity of diethyl 3,4-dimethoxybenzyl-phosphonate (XIV), which is closely related to Fostedil, is discussed.
