==Catalytic Domain Of Human Phosphodiesterase 4D In Complex With Cilomilast==
-
Phosphodiesterases (PDEs) comprise a large family of enzymes that catalyze, the hydrolysis of cAMP or cGMP and are implicated in various diseases. We, describe the high-resolution crystal structures of the catalytic domains, of PDE4B, PDE4D, and PDE5A with ten different inhibitors, including the, drug candidates cilomilast and roflumilast, for respiratory diseases., These cocrystal structures reveal a common scheme of inhibitor binding to, the PDEs: (i) a hydrophobic clamp formed by highly conserved hydrophobic, residues that sandwich the inhibitor in the active site; (ii) hydrogen, bonding to an invariant glutamine that controls the orientation of, inhibitor binding. A scaffold can be readily identified for any given, inhibitor based on the formation of these two types of conserved, interactions. These structural insights will enable the design of, isoform-selective inhibitors with improved binding affinity and should, facilitate the discovery of more potent and selective PDE inhibitors for, the treatment of a variety of diseases.

[https://www.uniprot.org/uniprot/PDE4D_HUMAN PDE4D_HUMAN] Note=Genetic variations in PDE4D might be associated with susceptibility to stroke. PubMed:17006457 states that association with stroke has to be considered with caution. Defects in PDE4D are the cause of acrodysostosis type 2, with or without hormone resistance (ACRDYS2) [MIM:[https://omim.org/entry/614613 614613]. ACRDYS2 is a pleiotropic disorder characterized by skeletal, endocrine, and neurological abnormalities. Skeletal features include brachycephaly, midface hypoplasia with a small upturned nose, brachydactyly, and lumbar spinal stenosis. Endocrine abnormalities include hypothyroidism and hypogonadism in males and irregular menses in females. Developmental disability is a common finding but is variable in severity and can be associated with significant behavioral problems.<ref>PMID:22464250</ref>
