Trihexyphenidyl
Based on 3 publication(s) in Google Scholar
Trihexyphenidyl is a selective and orally active M1 muscarinic receptor antagonist with an IC50 of 3.7 nM for rat cerebral cortex M1 muscarinic receptors. Trihexyphenidyl modulates cholinergic activity, countering acetylcholine supersensitivity in neural pathways. Trihexyphenidyl improves movement disorder, inhibits McN-A-343 (HY-107648)-induced pressor responses, vagally-induced bradycardia and vasodilatation. Trihexyphenidyl can be used for the research of Parkinson's disease..

Trihexyphenidyl (Varying concentrations; 45 min) binds with highest affinity to rat cerebral cortex M1 muscarinic receptors (IC50 = 3.7 nM), moderate affinity to rat submandibular gland receptors (IC50 = 17 nM), and lowest affinity to rat heart receptors (IC50 = 31 nM), with a selectivity ratio of 8 for heart versus cortex receptors[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Trihexyphenidyl (i.v.) shows moderate selectivity for M1 muscarinic receptor-mediated ganglionic nictitating membrane contractions over peripheral muscarinic receptor-mediated vagal bradycardia and vasodilatation in anaesthetized cats, with a selectivity ratio of 9[2].
