Description générale

α-Keto-γ-methylthiobutyric acid (KMTB) is a keto derivative of L-methionine that shows considerable potential as a substitute for L-methionine. The sodium salt of KMTB can be employed in nucleophilic substitution reactions. Additionally, it acts as a building block for the synthesis of amino acids, peptides, and other complex organic compounds.

Application


  • Measuring antioxidant capacity using the ORAC and TOSC assays.: This study details the use of α-Keto-γ-(methylthio)butyric acid sodium salt in assessing antioxidant capacity through ORAC and TOSC assays, emphasizing its utility in metabolic and chemical synthesis research (Garrett AR et al., 2010).

The CtBP transcriptional corepressors promote cancer cell survival and migration/invasion. CtBP senses cellular metabolism via a regulatory dehydrogenase domain, and is antagonized by p14/p19(ARF) tumor suppressors. The CtBP dehydrogenase substrate 4-methylthio-2-oxobutyric acid (MTOB) can act as a CtBP inhibitor at
