Disease

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: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.^[1]

Function

PDE4D_HUMAN Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.^[2] ^[3]

Publication Abstract from PubMed

Inflammatory Bowel Diseases (IBDs) are chronic disorders with iterative intestinal mucosal inflammation which remain unmet medical needs. PDE4 inhibitors were reported to be novel anti-IBD agents, but their clinical use was hampered by side effects such as emesis and nausea. Herein, structure-based discovery of natural mangostanin (1) targeting the M-pocket resulted in the novel and potent PDE4 inhibitor 22d (IC(50) = 3.5 nM) and favorable physico-chemical properties. X-Ray study revealed that 22d interacted tightly with the M-pocket and maintained the key interactions between PDE4 and roflumilast. Worthy to note that compounds 22d and our previously reported 4e and 18a, originating from mangostanin, all caused no emesis on beagle dogs at the oral dose of 10 mg/kg, confirming the safety superiority of scaffold in mangostanin derivatives over that in positive roflumilast. Finally, administration of 22d (5.0 mg/kg, twice-daily) exhibited comparable anti-IBD effects to the positive control dipyridamole (25.0 mg/kg, twice-daily) in the dextran sulfate sodium (DSS)-induced IBD mice model, indicating its potential as a novel anti-IBD agent.
