A series of glutamic acid derivatives was synthesized and evaluated for their antioxidant activity and stability. We found several potent and stable glutamic acid derivatives. Among them, compound 12b exhibited good in vitro activity, chemical stability and cytotoxicity. A prototype compound 12b showed an anti-inflammatory effect in LPS-stimulated RAW 264.7 cell lines and in a zebrafish model.

Disclosed is a method of the synthesis of ramalin. It comprises reacting a glutamic acid derivative, which is prepared using alkylchloroformate, with a hydrazine salt compound, which is prepared from hydroxy aniline, whether protected or not. The synthesis method allows ramalin, excellent in antioxidant and anti-inflammatory activity, to be simply synthesized at stable yield even without use of a highly toxic solvent such as DMF. In addition, the method is cost competitive, and provides ramalin at high efficiency, thus enabling the mass production of ramalin.

A new aryl-hydrazide l-glutamic acid derivative, pygmeine (3), was isolated from a methanolic extract of Lichina pygmaea, a marine lichen. Synthetic derivatives obtained via a two-step coupling of l-glutamic acid with phenylhydrazine moieties were useful
