Background:
Benztropine-13C-d3 is intended for use as an internal standard for the quantification of benztropine by GC- or LC-MS. Benztropine is an antagonist of M1 muscarinic acetylcholine receptors (Ki = 0.59 nM in rat brain membranes).1 It is selective for M1 receptors over the serotonin transporter (Ki = 5,150 nM), however, it also binds to the dopamine transporter and inhibits dopamine reuptake (Kis = 237 and 130 nM, respectively).1,2,3 Benztropine also inhibits acid sphingomyelinase by 87% when used at a concentration of 10 mM.4 Formulations containing benztropine have been used in the management of Parkinson's disease symptoms such as involuntary tremor and dystonia.
