Biochem/physiol Actions

PF-04447943 is a potent selective brain penetrant phosphodiesterase PDE9A inhibitor both potency (8 nM) and selectivity (>10 μM versus all the PDEs except PDE1C at >1 μM). It has been investigated for the treatment of cognitive disorders including Alzheimer′s Disease. PF-04447943 increased neurite outgrowth and synapse formation in hippocampal neurons in culture, exhibited synaptic stabilization in an amyloid precursor protein (APP) transgenic mouse model, and improved memory and enhanced attention in several animal models.

Selectivity for PDE9A over other PDE family members was achieved by targeting key residue differences between the

Several neurophysiological abnormalities have been described in Huntington's disease, including auditory gating deficit, which are considered to reflect impaired brain information-processing. Since transgenic animal models of Huntington's disease capture basic neuropathology of the disorder, auditory gating was studied in BACHD
