Type 4 phosphodiesterase (PDE4) inhibitors are emerging as new treatments, for a number of disorders including asthma and chronic obstructive, pulmonary disease. Here we report the biochemical characterization on the, second generation inhibitor (+)-1 (L-, IC50=0.4 nM) and its enantiomer, (-)-1 (L-, IC50=43 nM) and their cocrystal structures with PDE4D at 2.0 A, resolution. Despite the 107-fold affinity difference, both enantiomers, interact with the same sets of residues in the rigid active site. The, weaker (-)-1 adopts an unfavorable conformation to preserve the pivotal, interactions between the Mg-bound waters and the N-oxide of pyridine., These structures support a model in which inhibitors are anchored by the, invariant glutamine at one end and the metal-pocket residues at another, end. This model provides explanations for most of the observed, structure-activity relationship and the metal ion dependency of the, catechol-ether based inhibitors and should facilitate their further, design.

[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>
