l-cysteine-glutathione

L-Cysteine-glutathione disulfide is a potential biomarker for curing tuberculosis, present in mammalian cells with hepatoprotective effects, useful in acetaminophen-induced liver toxicity research.

Glutathione oxidized (L(-)-Glutathione) is a GLUTATHIONE dimer formed by a disulfide bond between the cysteine sulfhydryl side chains during the course of being oxidized.

L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

L-Cysteine hydrochloride hydrate (L-Cysteine hydrochloride monohydrate) is a conditionally essential amino acid, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), taurine and glutathione. L-Cysteine hydrochloride hydrate suppresses ghrelin and reduces appetite in rodents and humans.

D-Ribose-L-cysteine is the antioxidant glutathione precursor.

Ophthalmic acid is a glutathione analog in which cysteine is substituted by L-aminobutyrate.

S-(N-Methylsulfinylbutylthiocarbamoyl)-L-cysteine (SFN-Cys) is an isothiocyanate derivative, functioning as an active metabolite of sulforaphane, a class I and II histone deacetylase (HDAC) inhibitor, and anticancer agent. This compound is generated from sulforaphane through intermediates - DL-sulforaphane glutathione and sulforaphane cysteinylglycine - via the mercapturic acid pathway enzymes. At a concentration of 20 µM, SFN-Cys diminishes invasion and migration of U87MG and U373 MG glioblastoma cells as observed in wound healing and chamber assays. Furthermore, at 45 µM, it significantly lowers the expression of α-tubulin, βIII-tubulin, stathmin 1, and X-linked inhibitor of apoptosis (XIAP), and also reduces cell density in paclitaxel-resistant A549 lung cancer cells (A549/T). Additionally, when used at 30 µM, SFN-Cys prompts apoptosis and cell cycle arrest at the G2/M phase in U87MG and U373 MG cells.

L-Cysteine-d3 is a deuterated compound of L-Cysteine. L-Cysteine has a CAS number of 52-90-4. L-Cysteine is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture.
