Description:
TAK-063 is a highly potent, selective, and orally active phosphodiesterase 10A (PDE10A) inhibitor. TAK-063 is currently being evaluated in clinical trials for the treatment of schizophrenia. Phosphodiesterase 10A (PDE10A) is a cAMP/cGMP phosphodiesterase highly expressed in medium spiny neurons (MSNs) in the striatum. TAK-063 represents a promising drug for the treatment of schizophrenia with potential for superior safety and tolerability profiles.

1.TAK-063, a PDE10A Inhibitor with Balanced Activation of Direct and Indirect Pathways, Provides Potent Antipsychotic-Like Effects in Multiple Paradigms.
Suzuki K1, Harada A1, Suzuki H1, Miyamoto M1,2, Kimura H1. Neuropsychopharmacology. 2016 Feb 5. doi: 10.1038/npp.2016.20. [Epub ahead of print]
Phosphodiesterase 10A (PDE10A) inhibitors are expected to be novel drugs for schizophrenia through activation of both direct and indirect pathway medium spiny neurons. However, excess activation of the direct pathway by a dopamine D1 receptor agonist SKF82958 canceled antipsychotic-like effects of a dopamine D2 receptor antagonist haloperidol in methamphetamine (METH)-induced hyperactivity in rats. Thus, balanced activation of these pathways may be critical for PDE10A inhibitors. Current antipsychotics and the novel PDE10A inhibitor TAK-063, but not the selective PDE10A inhibitor MP-10, produced dose-dependent antipsychotic-like effects in METH-induced hyperactivity and prepulse inhibition in rodents. TAK-063 and MP-10 activated the indirect pathway to a similar extent; however, MP-10 caused greater activation of the direct pathway than did TAK-063. Interestingly, the off-rate of TAK-063 from PDE10A in rat brain sections was faster than that of MP-10, and a slower off-rate PDE10A inhibitor with TAK-063-like chemical structure showed an MP-10-like pharmacological profile.
2.The Phosphodiesterase 10A Selective Inhibitor TAK-063 Improves Cognitive Functions Associated with Schizophrenia in Rodent Models.
Shiraishi E1, Suzuki K1, Harada A1, Suzuki N1, Kimura H2. J Pharmacol Exp Ther. 2016 Mar;356(3):587-95. doi: 10.1124/jpet.115.230482. Epub 2015 Dec 16.
Cognitive deficits in various domains, including recognition memory, attention, impulsivity, working memory, and executive function, substantially affect functional outcomes in patients with schizophrenia. TAK-063 [1-[2-fluoro-4-(1H-pyrazol-1-yl)phenyl]-5-methoxy-3-(1-phenyl-1H-pyrazol-5-yl)pyridazin-4(1H)-one] is a potent and selective phosphodiesterase 10A inhibitor that produces antipsychotic-like effects in rodent models of schizophrenia. We evaluated the effects of TAK-063 on multiple cognitive functions associated with schizophrenia using naïve and drug-perturbed rodents. TAK-063 at 0.1 and 0.3 mg/kg p.o. improved time-dependent memory decay in object recognition in naïve rats. TAK-063 at 0.1 and 0.3 mg/kg p.o. increased accuracy rate, and TAK-063 at 0.3 mg/kg p.o. reduced impulsivity in a five-choice serial reaction time task in naïve rats. N-methyl-d-aspartate receptor antagonists, such as phencyclidine and MK-801 [(5R,10S)-(+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine], were used to induce working memory deficits relevant to schizophrenia in animals.

A novel series of pyridazinone-based phosphodiesterase 10A (PDE10A) inhibitors were synthesized. Our optimization efforts using structure-based drug design (SBDD) techniques on the basis of the X-ray crystal structure of PDE10A in complex with hit compound 1 (IC50 = 23 nM; 110-fold selectivity over other PDEs) led to the identification of 1-[2-fluoro-4-(1H-pyrazol-1-yl)phenyl]-5-methoxy-3-(1-phenyl-1H-pyrazol-5-yl)pyridazin-4(1H)-one (27h). Compound 27h 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. Oral administration of compound 27h to mice elevated striatal 3',5'-cyclic adenosine monophosphate (cAMP) and 3',5'-cyclic guanosine monophosphate (cGMP) levels at 0.3 mg/kg and showed potent suppression of phencyclidine (PCP)-induced hyperlocomotion at a minimum effective dose (MED) of 0.3 mg/kg. Compound 27h (TAK-063) is currently being evaluated in clinical trials for the treatment of schizophrenia.
4.In vivo pharmacological characterization of TAK-063, a potent and selective phosphodiesterase 10A inhibitor with antipsychotic-like activity in rodents.
Suzuki K1, Harada A1, Shiraishi E1, Kimura H2. J Pharmacol Exp Ther. 2015 Mar;352(3):471-9. doi: 10.1124/jpet.114.218552. Epub 2014 Dec 18.
Phosphodiesterase 10A (PDE10A) is a cAMP/cGMP phosphodiesterase highly expressed in medium spiny neurons (MSNs) in the striatum. We evaluated the in vivo pharmacological profile of a potent and selective PDE10A inhibitor, TAK-063 (1-[2-fluoro-4-(1H-pyrazol-1-yl)phenyl]-5-methoxy-3-(1-phenyl-1H-pyrazol-5-yl)-pyridazin-4(1H)-one). 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.
