Biological Activity

Description Mardepodect (PF-2545920) is a potent and selective PDE10A inhibitor with IC50 of 0.37 nM, with >1000-fold selectivity over the PDE.
Targets
PDE10A [2]
(Cell-free assay)
0.37 nM
In vitro

PF-2545920 shows excellent potency and selectivity of PDE10A with IC50 of 1.26 nM. [1]
In vivo PF-2545920 intraperitoneally administrated at dose of 0.3, 3, and 5 mg/kg in male CF-1 mice causes striking increases in GluR1 phosphorylation levels of 3-, 5.4-, and 4.1-fold , respectively. MP-10 at concentration of 1 μM treats Rat striatal slices for 30 min, the level of GluR1S845 phosphorylation at the cell surface is significantly increased 2-fold, without change the level of total GluR1 on the cell surface. MP-10 intraperitoneally administrated at dose of 0.3, 3, and 5 mg/kg in male CF-1 mice results in robust, statistically significant increases in CREBS133 phosphorylation of 3-, 4-, and 2.6-fold, respectively. MP-10 intraperitoneally administrated at dose of 3 mg/kg increases both enkephalin and substance-P mRNA levels in striatum of CF-1 mice. MP-10 intraperitoneally administrated at dose of 0.3-1 mg/kg decreases avoidance responding with a significant treatment effect in the mouse CAR model. Mice treated with MP-10 at dose of 0.03 mg/kg spents more time in the empty than social side in the mice, MP-10 also dose-dependently decreased locomotor activity. [1] PDE10A subcutaneously administrated at dose of 1 mg/kg elevates striatal cGMP about 3 fold in male CD-1 mice, while PDE10A subcutaneously administrated at dose of 3.2 mg/kg displays a maximal elevation of striatal cGMP approximately a 5-fold increase in male CD-1 mice. PDE10A intravenous injected at a dose of 0.1 mg/kg in Sprague-Dawley rats displays clearance of 36 ml/min/Kg, DE10A intravenous injected at a dose of 0.3 mg/kg in Dog Beagle displays clearance of 7.2 ml/min/Kg in vivo clearance with a moderate volume of distribution, DE10A intravenous injected at a dose of 0.03 mg/kg in Monkey Cynomolgus displays clearance of 13.9 ml/min/Kg in vivo clearance with a moderate volume of distribution. PDE10A is active with an ED50 of 1 mg/kg at a significantly lower total plasma exposure (115 nM) in the conditioned avoidance response assay (CAR) in Sprague-Dawley rats. [2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
