Researchers first developed the free radical scavenger edaravone in late 1980s as a treatment for stroke. The approach, introduced by Koji Abe, now at Okayama University Hospital in Japan, aimed to prevent the swelling of the brain which may occur after a stroke.
The free radical theory of aging states that organisms age because cells accumulate free radical damage over time. [1] A free radical is any atom or molecule that has a single unpaired electron in an outer shell. [2] While a few free radicals such as melanin are not chemically reactive, most biologically relevant free radicals are highly ...
The introduction of protein-based cross-links, [59] the introduction of free-radical scavenging molecules such as sorbitol, [60] and minimal stabilisation of the HA chains through chemical agents such as NASHA (non-animal stabilised hyaluronic acid) [61] are all techniques that have been used to preserve its shelf life.

The radical cyclization step usually involves the attack of a radical on a multiple bond. After this step occurs, the resulting cyclized radicals are quenched through the action of a radical scavenger, a fragmentation process, or an electron-transfer reaction. Five- and six-membered rings are the most common products; formation of smaller and ...
2-Methyl-2-butene, 2m2b, 2-methylbut-2-ene, beta-isoamylene, or Trimmethylethylene is an alkene hydrocarbon with the molecular formula C 5 H 10.. Used as a free radical scavenger in trichloromethane (chloroform) and dichloromethane (methylene chloride).
