Background:

Istradefylline-13C-d3is intended for use as an internal standard for the quantification of istradefylline by GC- or LC-MS. Istradefylline is an adenosine receptor 2A (A2A) antagonist (Ki= 2.2 nM in a radioligand binding assay).1In vivo, istradefylline inhibits catalepsy induced by haloperidol with an ED50value of 0.23 mg/kg in rats. Oral administration of istradefylline alleviates postural defects in a dose-dependent manner without inducing dyskinesias or hyperactivity in an MPTP-induced marmoset model of Parkinson's disease.2It also decreases bradykinesias induced by L-DOPA and improves attentional and working memory deficits in an MPTP-induced macaque model of Parkinson's disease.3Formulations containing istradefylline are used to extend on-time in Parkinson's disease patients experiencing motor fluctuations.
