L-Kynurenine is a key intermediate in the breakdown of L-tryptophan and the formation of nicotinamide adenine dinucleotide (NAD+) via the kynurenine pathway. It is involved in a variety of neurological processes and diseases. L-Kynurenine is a substrate for kynureninase/kynurenine hydrolase; kynurenine 3-monooxygenase and kynurenine-oxoglutarate transaminase.

Levadopa Related Compound A is the 6-hydroxy derivative of the amino acid L-DOPA with neurotoxic properties. Studies show that exogenously administered 6-Hydroxy-L-DOPA is biotransformed by amino acid decarboxylase to the highly potent and catecholamine-selective neurotoxin, 6-Hydroxydopamine. The treatment of 6-Hydroxy-L-DOPA in rats resulted in the stimulation of acetylcholinesterase.

Aceglutamide is a psychostimulant, nootropic, and antiulcer agent that is marketed in Spain and Japan. It is an acetylated form of the amino acid L-glutamine, the precursor of glutamate in the body and brain. Aceglutamide functions as a prodrug to glutamine with improved potency and stability. Aceglutamide is used as a psychostimulant and nootropic, while aceglutamide aluminum is used in the treatment of ulcers. Aceglutamide can also be used as a liquid-stable source of glutamine to prevent damage from protein energy malnutrition. The drug has shown neuroprotective effects in an animal model of cerebral ischemia.

S-Ethyl glutathione is an inhibitor of the enzyme Glyoxalase 1.

S-methyl glutathione is a methionine containing peptide and glyoxylase inhibitor.

Dicentrine, (-)- is an aporphinic alkaloid found in several plant species, mainly from Lauraceae family, which showed significant antinociceptive activity in an acute model of visceral pain in mice. It has also been shown to reduce spontaneous nociception and attenuating mechanical and cold hypersensitivity, probably via a TRPA1-dependent mechanism.

N-Monoacetylcystine is an antidote for paracetamol poisoning. It is also an antioxidant, used in the treatment of influenza A virus pandemic. N-Acetyl-L-cystine promotes fertilization by reducing disulfide bonds in zona pellucida of mouse.

Butyrylcarnitine is elevated in patients with Acyl-CoA dehydrogenase, short-chain (SCAD) deficiency, in infants with acute acidosis and generalized muscle weakness and in middle-aged patients with chronic myopathy localized in muscle; very long chain Acyl-CoA dehydrogenase deficiency, and celiac disease.

Benzoylphenylalanine is a photoaffinity label.

Argininosuccinic acid is an amino acid formed during the urea cycle from citrulline, aspartate and ATP. This reaction is catalyzed by argininosuccinic acid synthetase.

Amoxicillin, L- is an antibiotic useful for the treatment of a number of bacterial infections.

Pepstatin inhibits the aspartic protease endothiapepsin.

Methyldopate HCl si an antihypertensive.

Selenocystine, L- is used as a building block in biologically active selenol compounds.

Oxydisulfoton is an insecticide.

Chinomethionat is an acaricide, insecticide and fungicide.

Allura Red AC is a red azo dye that goes by several names.[1] It is used as a food dye and has the E number E129. It is usually supplied as its dark red sodium salt, but can also be used as the calcium and potassium salts. These salts are soluble in water. In solution, its maximum absorbance lies at about 504 nm.
