[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> | |||

== Publication Abstract from PubMed == | |||
Psoriasis is a common immune-mediated skin disorder manifesting in abnormal skin plaques, and phosphodiesterase 4 (PDE4) is an effective target for the treatment of inflammatory diseases such as psoriasis. Toddacoumalone is a natural PDE4 inhibitor with moderate potency and imperfect drug-like properties. To discover novel and potent PDE4 inhibitors with considerable druggability, a series of toddacoumalone derivatives were designed and synthesized, leading to the compound (2R,4S)-6-ethyl-2-(2-hydroxyethyl)-2,8-dimethyl-4-(2-methylprop-1-en-1-yl)-2,3,4, 6-tetrahydro-5H-pyrano[3,2-c][1,8]naphthyridin-5-one (33a) with high inhibitory potency (IC50 = 3.1 nM), satisfactory selectivity, favorable skin permeability, and a well-characterized binding mechanism. Encouragingly, topical administration of 33a exhibited remarkable therapeutic effects in an imiquimod-induced psoriasis mouse model. | |||
