Biological Activity

TAK-063 has potent inhibitory activity (IC50 = 0.30 nM), excellent selectivity (>15000-fold selectivity over other PDEs), and favorable pharmacokinetics, including high brain penetration, in mice.TAK-063 at 0.3 and 1 mg/kg p.o., increased cAMP and cGMP levels in the rodent striatum and upregulated phosphorylation levels of key substrates of cAMP- and cGMP-dependent protein kinases. TAK-063 at 0.3 and 1 mg/kg p.o., strongly suppressed MK-801 [(5R,10S)-(+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine]-induced hyperlocomotion, which is often used as a predictive model for antipsychotic-like activity in rodents. Upregulation of striatal cAMP/cGMP levels and the antipsychotic-like effect of TAK-063 were not attenuated after 15 days of pretreatment with TAK-063 in mice. The potential side effect profile of TAK-063 was assessed in rats using the clinical antipsychotics haloperidol, olanzapine, and aripiprazole as controls. TAK-063 did not affect plasma prolactin or glucose levels at doses up to 3 mg/kg p.o. At 3 mg/kg p.o., TAK-063 elicited a weak cataleptic response compared with haloperidol and olanzapine.Evaluation of pathway-specific markers (substance P mRNA for the direct pathway and enkephalin mRNA for the indirect pathway) revealed that TAK-063 activated both the direct and indirect pathways of MSNs.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
