l-cysteine s-sulfate

L-Cysteine S-sulfate (S-Sulfo-L-cysteine) is an effective N-methyl-d-aspartate (NMDA) glutamatergic receptors agonist. L-Cysteine S-sulfate is the substrate for cystine lyase [1].

L-Cysteine S-sulfate sodium salt sesquihydrate is a sulfated derivative of cysteine that structurally mimics excitatory amino acids and acts as an agonist for glutamate receptors (such as NMDA receptors). In neuroscience research, L-Cysteine S-sulfate sodium salt sesquihydrate is commonly used to induce excitotoxicity models to study neuronal damage and the underlying signaling pathways.
