PF-04449613 is a phosphodiesterase 9A (PDE9A) inhibitor (IC50 = 22 nM).{54234} It is selective for PDE9A over PDE1C (IC50 = >1,000 nM), as well as over a variety of other PDEs, inhibiting PDE2-8, -10, and -11 activity by less than 30% in a panel of enzymes, ion channels, and transporters at 1 µM but does inhibit the human dopamine transporter (DAT; Ki = 293 nM). PF-04449613 (0.1-100 mg/kg, s.c.) increases cerebrospinal fluid (CSF) levels of cyclic GMP (cGMP) in rats. Subcutaneous administration of PF-04449613 (10 mg/kg) increases the rate of dendritic spine formation and elimination in mouse primary motor cortex pyramidal neurons in vivo.{54235} It increases the average running speed of mice in an accelerating rotarod task, indicating improved motor learning, at the same dose.
