N-Acetyl-L-tryptophan-d₃ 

N-Acetyl-L-tryptophan-d₃ is the deuterium labeled N-Acetyl-L-tryptophan (HY-W011978). N-Acetyl-L-tryptophan is an antagonist of the neurokinin-1 receptor (NK-1R), disrupting the binding of substance P (SP) to NK-1R. This action provides neuroprotective effects, improving memory deficits and motor impairments. N-Acetyl-L-tryptophan is also an inhibitor of cytochrome c (Cytochrome c), and it exerts antioxidant and anti-inflammatory effects by inhibiting the expression of IL-1β and the activation of caspase-1. N-Acetyl-L-tryptophan holds promise for research in neurodegenerative and inflammatory diseases^[1][2][3][4].

2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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.
