Abstract

The invention provides a new use of salidroside, and specifically, relates to a use in preparation of complement inhibitor drugs. The salidroside drug can act on a lectin pathway and a classical pathway in a complement system, directly inhibits the activation of complement systems of nerve cells, vascular endothelial cells and other brain cells, plays a neuroprotective role, can effectively treatneuroinflammatory or neurodegenerative diseases, has the advantages of clear drug efficacy, controllable quality and safety, and provides a new choice for the clinic.

Description

technical field [0001] The present invention relates to the new application of salidroside, specifically, the application in the preparation of complement inhibitor drugs. Background technique [0002] The complement system is a group of proteins that exist in human and animal body fluids and on the surface of cells, are biologically active after activation, and can mediate immune and inflammatory responses. The complement system is widely involved in the body's microbial defense response and immune regulation, and can also mediate the damage response of immunopathology. It is an effector system and effect amplification system with important biological functions in the body. [0003] The complement system not only plays an important defense role in the body, but also plays an important role in various physiological activities and homeostasis. It can participate in the catabolism of immune complexes, the removal of necrotic cells, and the regulation of adaptive immune respons...
