Description: PF-04447943 (Edelinontrine) is a potent and selective phosphodiesterase 9A inhibitor with an IC50 of 12 nM, which is 78-fold more selective than that used for other PDE family members (IC50>1000 nM).PF-04447943 exhibits anti-inflammatory activity, attenuates inflammatory responses by inhibiting...

PF-04447943 is a brain-permeable phosphodiesterase (PDE) inhibitor that is selective for PDE9A (IC50 = 12 nM) over other PDEs (IC50s = >940 nM) in enzymatic assays of second messenger hydrolysis. It is over 1,000-fold more selective for PDE9A over 79 non-PDE targets, with the exception of the melatonin MT3/ML2...
