L-Cysteinesulfinic acid is an endogenous neurotransmitter with agonistic effects on a variety of metabotropic glutamate receptors (mGluRs), including mGluR1, mGluR5, mGluR2, mGluR4, mGluR6, and mGluR8, with a pEC50 = 2.7 to 4.0. L- Cysteinesulfinic acid is a pld-coupled agonist of metabotropic excitatory amino acid (EAA) receptors.

DL-Cysteine (Standard) is a reference standard for DL-Cysteine, suitable for quantitative analysis, quality control, and biochemical experiments.At high concentration, DL-Cysteine acts as an agonist for NMDA/quisqualate receptors and is commonly used in exploring neurobiological mechanisms.

Acetylcysteine (NAC) is an N-acetyl derivative of cysteine, a ROS inhibitor and mucolytic agent. Acetylcysteine induces apoptosis, can be used to reduce mucus thickness, and has anti-influenza viral activity.

Penicillamine (Artamine), possessing antineoplastic properties, induces apoptosis by a p53-mediated mechanism and inhibits angiogenesis by chelating with copper, a cofactor for angiogenesis. Artamine is a beta dimethyl analog of the amino acid cysteine. As a degradation product of penicillin antibiotics, Artamine chelates with heavy metals and increases their urinary excretion.

S-Allylmercapturic Acid (N-Acetyl-S-allyl-L-cysteine) is a metabolite of S-allyl-L-cysteine present in black garlic with potential anti-gout effects, inhibiting both CYP2D6 and CYP-catalyzed reactions.

Gamma-glutamylcysteine TFA (γ-glutamylcysteine TFA) is a precursor of glutathione (GSH) with antioxidant and anti-inflammatory properties. It alleviates oxidative stress and mitochondrial damage induced by ethanol in hepatocytes by increasing cellular GSH, SOD activity, and mitochondrial membrane potential, protecting cells from alcohol-induced liver disease (ALD) by inhibiting oxidative stress, reducing inflammation, and preventing cell apoptosis.
