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

Phosphodiesterase-4 (PDE4) is an important drug target for treatment of inflammation-related diseases. Till now, natural PDE4 inhibitors are rare and their co-crystal structures with PDE4 are hardly available. In the present study, selaginpulvilins K and L (1 and 2), two novel fluorene derivatives, were isolated from a traditional Chinese medicine Selaginella pulvinata and exhibited remarkable inhibition against phosphodiesterase-4D (PDE4D) at IC50 11nM and 90nM, respectively. Compound 1 also showed a good selectivity across PDE families with the selective fold ranging from 30 to 909. To understand the recognition mechanism of selaginpulvilins towards PDE4, the crystal structure of PDE4D bound with 1 was successfully determined by the X-ray diffraction method and presented an unusual binding mode in which the stretched skeleton of the inhibitor bound shallowly to the active site but had interactions with multi sub-pockets, such as Q, HC, M, and S, especially strong interaction with the metal region. Assisted with molecular modeling, the structure-activity relationship and the selectivity of selaginpulvilins were also well explored, which would facilitate the future rational inhibitor design or structural optimizations.

The discovery, complex crystal structure, and recognition mechanism of a novel natural PDE4 inhibitor from Selaginella pulvinata.,Huang Y, Liu X, Wu D, Tang G, Lai Z, Zheng X, Yin S, Luo HB Biochem Pharmacol. 2017 Jan 31. pii: S0006-2952(17)30046-1. doi:, 10.1016/j.bcp.2017.01.016. PMID:28159622^[4]
