Edaravone is a new type of free radical scavenger that was first launched in Japan in April 2001 and is mainly used clinically for the treatment of ischemic stroke. Edaravone exists in the form of an anion and can provide one electron to free radicals to achieve the goal of scavenging free radicals. Due to its molecular structure containing lipophilic groups, it is easy to reach brain tissue through the blood-brain barrier and has a protective effect on neural cell damage caused by cerebral ischemia.
Mainly used for synthesizing pyrazolone antipyretic and analgesic drugs such as analgin, antipyrine, and aminopyrine; It is also an intermediate of pyrazolone acid dyes such as acidic mordant magenta BN, eternal yellow G, as well as color film dyes, pesticides, and other fine chemicals.
