Function
[PDE10_RAT] Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. Can hydrolyze both cAMP and cGMP, but has higher affinity for cAMP and is more efficient with cAMP as substrate.[1]

Publication Abstract from PubMed
Novel imidazo[1,5-a]pyrido[3,2-e]pyrazines have been synthesized and characterized as both potent and selective phosphodiesterase 10A (PDE10A) inhibitors. For in vitro characterization, inhibition of PDE10A mediated cAMP hydrolysis was used and a QSAR model was established to analyze substitution effects. The outcome of this analysis was complemented by the crystal structure of PDE10A in complex with compound 49. Qualitatively new interactions between inhibitor and binding site were found, contrasting with previously published crystal structures of papaverine-like inhibitors. In accordance with the known antipsychotic potential of PDE10A inhibitors, MK-801 induced stereotypy and hyperactivity in rats were reversed by selected compounds. Thus, a promising compound class has been identified for the treatment of schizophrenia that could circumvent side effects connected with current therapies.
