1. Application of 3-Nitro-L-tyrosine CAS 621-44-3:

3-Nitro-L-tyrosine is a nitrosylation modification product of protein tyrosine residues mediated by peroxynitrite, primarily serving as a biomarker for assessing oxidative and nitrosative stress.
In medical research, 3-nitro-L-tyrosine is extensively employed to monitor the progression of neurological disorders (such as neurodegenerative diseases) and cardiovascular conditions. Elevated levels correlate with excessive nitric oxide production and oxidative damage, enabling prediction of disease severity in conditions like hepatic injury.
Within the biotechnology sector, this compound frequently serves in antibody preparation and immunoassays. For instance, it is conjugated with carriers like bovine serum albumin to create artificial antigens, subsequently enabling the development of highly sensitive detection tools such as ELISA or molecularly imprinted polymers. This facilitates precise quantitative analysis of 3-nitro-L-tyrosine within biological samples.
In pharmacological studies, 3-nitro-L-tyrosine has been found to modulate angiotensin II-induced haemodynamic changes by inhibiting α1-adrenergic receptor-mediated responses, suggesting potential biological activity in cardiovascular function regulation.
