Antiinflammatory activity of methionine, methionine sulfoxide and methionine sulfone
Agents and Actions, 1990The oxidation of methionine in peptides is often associated with the loss of biological activity. Since methionine showed good antiinflammatory activity, its oxidized products methionine sulfoxide and methionine sulfone were tested. The sulfone was more active than the sulfoxide although methionine was most active indicating that the antiinflammatory ...

Purpose of review In this review, we summarize the biological roles of methionine, methionine adenosyl transferase 2A (MAT2A) and S-adenosyl methionine (SAM) in methylation reactions during tumorigenesis. Newly emerged inhibitors targeting the methionine−MAT2A−SAM axis will be discussed. Recent

C(α)-C(β) chromophore bond dissociation in some selected methionine-containing dipeptides induced by UV photons is investigated. In methionine containing dipeptides with tryptophan as the UV chromophore, the tryptophan side chain is ejected either as an ion or as a neutral fragment while in dipeptides with tyrosine, the tyrosine side chain is lost only

L-Methionine has been used in various industrial applications such as the production of feed and food additives and has been used as a raw material for medical supplies and drugs. It functions not only as an essential amino acid but also as a physiological effector, for example, by inhibiting fat accumulation and enhancing immune response.

In 1944 Albanese, Frankston and Irby1 published their hydrogen peroxide – perchloric acid oxidation method for the estimation of methionine in protein hydrolysates and human urine. They stated: “… the applicability of the procedure to the urine was established by means of a study which demonstrated that the normal urinary constituents failed to react ...

11C-Methionine (11 C-METH) is an aminoacidic PET tracer whose main employment regards the diagnosis of central nervous system tumors. Methionine is, in fact, one of the five essential amino acids that can be involved in different metabolic pathways at a cellular level.

Abstract The metabolic pathways of methionine sulphoxide and methionine sulphone were investigated employing a combination of gas chromatography, thin-layer chromatography, paper chromatography, and radioactive methods of analyses. Gas chromatographic analysis demonstrated that methionine, methionine sulphoxide, and methionine sulphone all yielded ...
