title: Drug latentiation of isoxsuprine: synthesis and preliminary pharmacological activities of four monoesters.
abstract: Four new esters (1 b-e) involving the phenolic group of isoxsuprine have been prepared. Preliminary pharmacological evaluation showed that the pivaloyl ester (1 e) (LR693) lowers blood pressure values more gradually than isoxsuprine with a longer-lasting effect. This compound was selected for further assessment as a long-acting peripheral vasodilator.
