Secoverine
Secoverine is a muscarinic cholinergic receptor (mAChR) antagonist and antispasmodic with blood-brain barrier permeability. Secoverine binds competitively to muscarinic receptors, blocks central cholinergic effects, and inhibits cholinergically induced gastrointestinal motility, intestinal smooth muscle contraction, and acetylcholine-mediated neurotransmitter release. Secoverine exerts direct antispasmodic activity on intestinal smooth muscle independent of receptor blockade, and exhibits characteristics such as reversible smooth muscle activity and long duration of action. Secoverine can be used in studies related to hyperintestinal motility, diverticular disease, and colonic spasm.

Biologische Aktivität
Secoverine acts as a non-selective high-affinity muscarinic antagonist, exhibiting identical binding affinity for rat cardiac M2, rat cerebral cortex M1, and rat cerebral cortex M2 muscarinic receptors[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Secoverine (intravenous administration, dose 2.0-3.7 mg/kg) exhibits transient, slight mydriatic activity in female Swiss CPB mice[2].
Secoverine (intravenous injection, 3.48-6.81 mg/kg) potently antagonizes oxotremorine (HY-170032)-induced central tremor in male Swiss CPB mice, with ED50 values ranging from 3.48 to 6.81 mg/kg at 1 to 20 minutes post intravenous administration[2].
