Problems solved by technology

[0003] The first generation of PDE4 inhibitors such as rolipram has a good antidepressant effect, the reason why it cannot be marketed is the side effects such as nausea and vomiting caused by the inhibition of PDE4
Compared with the first-generation PDE4 inhibitors, the second-generation PDE4 inhibitors have better therapeutic effects, but so far no PDE4 inhibitors that can prevent vomiting have been marketed

Abstract

The present invention relates to a kind of Phosphodiesterase 4 inhibitors without vomiting, which is compounds or a prodrugs or solvates represented by formula (I), R 1 is an independent methoxy, bromine and substituted aryl; X is an optionally substituted six-membered heterocyclic ring; Y is -(CH 2 ) n -, -NH(CH 2 ) n -, and-NH(CH 2 ) n -O-, wherein n is any value among 0, 1, 2 and 3; Z is an optionally substituted aromatic ring or an optionally substituted heteroaromatic ring. The present invention is relates to a kind of Phosphodiesterase 4 inhibitors without vomiting, which is a novel biphenyl series PDE4D inhibitor, and can be applied to treat depression and Alzheimer's disease, improve cognitive ability and avoid vomiting.

Description

technical field [0001] The present invention relates to the technical field of compounds capable of inhibiting phosphodiesterase, especially a biphenyl PDE4D inhibitor, specifically a phosphodiesterase 4 inhibitor capable of avoiding vomiting. Drugs can be used to treat depression, Alzheimer's disease and improve cognition. Background technique [0002] Phosphodiesterase 4 (PDE4) is mainly distributed in inflammatory cells (mast cells, macrophages, lymphocytes and epithelial cells) and nerve cells. PDE4 is closely related to the functions of the central nervous system and the immune system, and its inhibitors are considered to be new anti-inflammatory drugs and central nervous system drug candidates acting on intracellular targets. Since PDE4 specifically catalyzes the hydrolysis of cAMP, it plays a key role in regulating the concentration of intracellular cAMP. Inhibiting PDE4 causes cAMP to accumulate in cells and produce various biological effects, including anti-inflamm...
