Abstract

The invention relates to a phosphodiesterase 4 inhibitor capable of avoiding a vomiting reaction. The phosphodiesterase 4 inhibitor is a compound or a pro-drug or a solvate represented by formula (I), wherein R1 is independent methoxyl, bromine and substituted aryl; X is a randomly substituted six-membered heterocycle; Y is -(CH2)n-, -NH(CH2)n- and -NH(CH2)n-O-, wherein n can be any one of 0, 1, 2 or 3; and Z is a randomly substituted aromatic ring or a randomly substituted heteroaromatic ring. The phosphodiesterase 4 inhibitor capable of avoiding the vomiting reaction is a novel biphenyl PDE4D inhibitor which is applicable to treating depression and Alzheimer's disease and improving cognitive competence, and is capable of avoiding a side effect such as the 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...
