Novel type of carbon-centered antioxidants arylmethyl Meldrum’s acids inhibit free radicals

Abstract

Arylmethyl Meldrum’s acids should be highlighted as potential antioxidants for increasing oxidative stability of various products containing, for example, esters of poly-unsaturated fatty acids. It should be admitted that the structure of the title compounds can be widely modified by substituents in the aromatic ring without remarkable loss of antioxidant and antiradical activity, but other properties (like solubility) may be improved. In order to apply the title antioxidants into products like cosmetics additional tests regarding toxicity are required. However, these antioxidants can be recommended for increasing oxidative stability for products used in technique.
