Problems solved by technology

Our use of a D3 partial agonist to treat withdrawal-induced compulsive behaviors in morphine-addicted mice is highly effective, strongly suggesting that this new class of drug may control the addiction-driven compulsive seeking in heroin addicts drug behavior

Abstract

The present invention relates to a tricyclic compound or its stereo-isomer or its pharmaceutically-acceptable salt and their application in preparation of medicine for curing the disease of central nervous system. Besides, said invention also provides the chemical general formula of said tricyclic compound and its detailed description.

Description

technical field [0001] The invention belongs to the field of chemical medicine, and relates to a dopamine D3 receptor partial agonist, namely a tricyclic compound, and its application in pharmacy. Background technique [0002] The dopamine receptor subtype belongs to the G protein-coupled receptor family with 7 transmembrane domains. Seeman in 1988 divided the dopamine receptor subtypes into two families according to the difference in sequence and signal transduction coupling: D 1 dopamine-like receptors including D 1 and D 5 Receptor; D 2 dopamine-like receptors including D 2 ,D 3 and D 4 receptor. D. 2 The receptor is the main binding target of traditional antipsychotic drugs, but can cause extrapyramidal side effects. D. 3 Receptors are mainly concentrated in dopamine neural pathways in the limbic system of the brain, which is associated with emotional and cognitive functions. In the nerve structure of the limbic system, there are endogenous enkephalins and end...
