AI Technical Summary
Technical Problem
There is a lack of compounds with high selectivity and good pharmaceutical value for σ1 receptors in the current technology for the treatment of central nervous system diseases such as pain and mental illness.
Method used
A compound with a bicyclic structure, having specific aromatic ring groups and alkylamine substituents, was designed as a selective inhibitor of the σ1 receptor. Compounds with different substitution forms were synthesized to improve the affinity and selectivity for the σ1 receptor.
Benefits of technology
This compound exhibits significant inhibitory activity against σ1 receptors, effectively treating pain, particularly neuropathic and inflammatory pain, and its pain-relieving effect is enhanced when used in combination with morphine.

Abstract
The present application relates to the chemical medicine field, especially to a kind of sigma-1 receptor inhibitor of double ring structure. Specifically provide a kind of unique double ring structure compound of structure, it has good σ1 receptor affinity and selectivity, is the strong selective inhibitor of σ1 receptor. The double ring structure compound has the basic group structure of double aromatic ring, and the characteristic that the isoside skew symmetry position of intermediate aromatic bicyclic is respectively replaced by another double aromatic ring and alkylamine directly connected with aromatic ring.
