Abstract

The invention discloses an application of a TRPV4 ion channel as a drug target in organophosphorus compound poisoning. A medicine is a TRPV4 inhibitor. The medicine comprises: pharmacological antagonists of TRPV4 including GSK2193874, HC-067047, GSK205, GSK3395879, RN-1734 and GSK2798745, a blocking type antibody of the TRPV4, siRNA of the TRPV4 and the like. The important point of the invention is that the TRPV4 is found to be closely related to brain injury caused by the organophosphorus compound poisoning; and the TRPV4 antagonists or the siRNA inhibits intracellular calcium flow caused bythe organophosphorus compound poisoning and NMDA receptor-mediated excitatory toxicity, so that the nervous system toxic effect induced by poisoning of two organophosphorus compounds including oxophosphorus and soman is remarkably reduced at both in-vivo and in-vitro levels. Therefore, the invention provides a new drug target for prevention and treatment of the organophosphorus compound poisoning,and provides a new strategy for clinical treatment of the organophosphorus compound poisoning.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the application of TRPV4 ion channel as a drug target in organophosphorus compound poisoning. Background technique [0002] Organophosphorus compounds are widely used in agricultural and military fields. This type of compound inhibits the activity of acetylcholinesterase, resulting in the excessive accumulation of acetylcholine in the body, which causes severe dysfunction of the central and peripheral cholinergic nervous system, and at the same time disrupts the excitatory neurotransmitter system and triggers inflammatory reactions in the later stage, eventually leading to severe Brain Injury. Common organophosphorus compounds can be divided into military nerve agents (nerve agents) and organophosphate pesticides (organophosphate pesticides, OPS) according to their uses. Among them, military nerve agents are represented by tabun, sarin, soman and Viex (VX), which have been used many tim...
