Key Product Details
Description
Potent PDE9 inhibitor; brain penetrant
Alternative Names
PF 9613
Product Description
PF 04449613 is a potent PDE9 inhibitor (IC50 = 22 nM). PF 4449613 shows more than 1000-fold selectivity for PDE9A over most of 79 other non-PDE targets investigated, except for cytochrome P450 2C19 (IC50 = 1600 nM), dopamine transporter (Ki = 110 nM), μ-opioid receptor (Ki =3500 nM), and sodium channel binding site 2 (Ki =470 nM). PF 04449613 reduces body fat in mice with diet-induced obesity, stimulating mitochondrial activity in brown and white fat, and improving cardiometabolic syndrome symptoms. Brain penetrant. PF 04449613 increases synaptic calcium activity and learning-dependent synaptic plasticity in mice.Licensing Information
