Problems solved by technology

In 2016, the inventors applied for a general, simple and effective total synthesis method of Bupleinol (1) and its analogue RB-2 (2), obtaining a certain amount of natural product, and then in the injury of PC12 cells by corticosteroids. In the protection experiment, it was proved that RB-2 did not protect nerve cells, on the contrary, it still had a certain damage effect on PC12 cells

Abstract

The invention belongs to the technical field of medicinal chemistry, particularly relates to conjugated dialkynediol compounds and an application thereof and aims to provide conjugated dialkynediol compounds having a protection function on nerve cells. The compounds have a protection function on corticosterone injured PC12 cells. The conjugated dialkynediol compounds have the following general structural formula shown in the specification, wherein R1 represents -(CH2)N-, and n ranges from 2 to 8; -CH=CH-(CH2)m-, m ranges from 1 to 8; in -phenyl (CH2)o-(o-, meta-, p-), o ranges from 1 to 8.

Description

technical field [0001] The invention belongs to the technical field of medicinal chemistry, and in particular relates to a conjugated diacetylene glycol compound and its application. Background technique [0002] Depression is a common mental illness characterized by high morbidity, relapse and disability [1] . Its harm has attracted more and more attention from the medical and health circles in the world. However, the clinical curative effect of the existing antidepressant western medicine is not satisfactory, and there are still problems such as narrow antidepressant spectrum, large side effects, slow onset of effect, easy recurrence and high drug price, so the development of a new generation of antidepressant drugs is a research hotspot. [0003] The pathogenesis of depression is still unclear. In recent years, a large number of experiments and clinical observations have shown that atrophy or destruction of hippocampal neurons may be the pathogenesis of depression (Fuch...
