Medchemexpress LLC L-Valine-13C5,15N | 202407-30-5 | 123.10 | 25 MG
L-Valine-13C5,15N is the 13C- and 15N-labeled L-Valine. It is a nonlinear semiorganic material that causes lipid peroxidation and accumulation of malondialdehyde (MDA), and exhibits inhibitory activity against cyanobacteria. This compound inhibits multidrug-resistant bacteria through activation of PI3K/Akt signaling pathway and inhibition of arginase. Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs.
