Problems solved by technology

However, due to the tolerance and dependent side effects of this type of drug, its application is greatly limited.
κ-opioid receptor agonists also have powerful analgesic effects, but are low in addiction. Therefore, research and development of new opioid analgesics with low addiction is of great clinical significance

The general structural formula of the compound is shown in (I), wherein, R is H, straight chain or branch chain alkyl of C1 to C10, aromatic group or aliphatic heterocyclic or non-heterocyclic substituted alkyl; X is H, -OH, alkoxy, amido, substituted amido, carboxyl, ester group, aminoacyl; Y is H, -OH, alkoxyl, amido, substituted amido, etc., and Z is various substituted pentagon, hexagon or substituted pentagon, hexagon aromatic and aliphatic heterocycle.

Description

technical field [0001] The present invention relates to a class of aromatic or aliphatic heterocyclic condensed morphinan compounds, the synthesis method and its use as an opioid receptor agonist or antagonist for the treatment of drug abuse and brain dysfunction related to drug abuse, and as a novel Uses such as analgesics. Background technique [0002] Drug abuse is a serious social and economic problem that directly endangers human health and destroys family unity. It is a chronic disease of the brain caused by long-term excessive use of excitatory substances such as cocaine and heroin. It is characterized by a slow course of disease and high relapse, accompanied by obvious psychological, intellectual and behavioral disorders [Crome, HB. Drug Alcohol Depend. 1999, 55: 247-263; NIDA (2000): Epidemiologic Trends in Drug Abuse, NIH Publication No. 00-4739A. National Institute on Drug Abuse, 99]. In recent years, with the development of neurobiology, neuropharmacology, mol...
