PF-04447943

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 oxidative stress, inflammation, and modulating T-cell polarization, and may be useful for research on sickle cell anemia. Target: PDE. Smiles: C[C@@H]1CN(Cc2ncccn2)C[C@H]1c1nc2n(ncc2c(=O)[nH]1)C1CCOCC1. References: Kleiman RJ, et al.
