Optical Activity ( + / - )

Ecadotril or sinorphan is the S-enantiomer of racemic acetorphan (racecadotril). It inhibits enkephalinase activity. Ecadotril was studied for the treatment of hypertension and heart failure, however, its development was discontinued.

CNS Activity

Curator's Comment: Ecadotril ((S)-acetorphan) is CNS active in animals when administered parenterally. No human data available.

Sample Use Guides

Mice: 300 mg/kg
Route of Administration: Intraperitoneal
In saturation binding studies in various mouse tissues [3H]-thiorphan exhibited an affinity (Kd value) of 0.46–0.77 nM, and the density of [3H]-thiorphan binding sites was well correlated with measured enkephalinase activity in a panel of 11 different mouse tissues.
