(In Vitro)

Sarizotan concentration-dependently inhibits the electrically-induced contractions with an IC50 value of 150 nM (Emax 40% at 1 mM) [1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

(In Vivo)

Sarizotan (3, 10 mg/kg, po) at the higher dose slightly decreases 5-HT in the striatum and its metabolite 5-HIAA in frontal cortex and hippocampus. Sarizotan (10 mg/kg, po) substantially increases the DA metabolites DOPAC and HVA in the striatum and frontal cortex[1].
Sarizotan represents a new approach for the treatment of extrapyramidal motor complications such as l-DOPA-induced dyskinesia in Parkinson’s disease[1].
Sarizotan (10 ng and 1 μg, local administration) attenuates levodopa-induced dyskinesias in 6-OHDA-lesioned rats[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague-Dawley rats weighing 220-240 g (exhibiting a vigorous rotational response)[2].
Dosage: 1 ng, 10 ng and 1 μg in 0.3 μL solution.
Administration: Administered via an injection cannula inserted to the guide cannula through the STN (V -8.4 mm from skull) with the injection cannula connected to a 10-μL syringe and mounted on a microinfusion pump for 22 consecutive days.
Result: On day 23, the subthalamic administration of Sarizotan at the higher doses tested (10 ng and 1 μg) significantly decreased the total dyskinesia score in levodopa-treated rats in comparison with the rats treated only with levodopa (p<0.05, p<0.01, respectively).
