Amino Acids and Derivatives

Pepstatin (Pepsin Inhibitor S 735A) is an aspartate protease inhibitor that also inhibits HIV protease activity with specific and oral activity. Pepstatin inhibits autophagy.

L-Tryptophan (Tryptophane), an essential amino acid, is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid) and of INDOLE ALKALOIDS in plants. It can be a precursor to NIACIN, although inefficiently in mammals.

L-Ornithine ((S)-2,5-Diaminopentanoic acid) exhibits an anti-fatigue function by promoting ammonia excretion and enhancing energy consumption efficiency.

L-Tyrosine ((S)-Tyrosine) is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine, considered a non-essential amino acid. L-Tyrosine(L-p-Tyrosine) is the levorotatory isomer of the aromatic amino acid tyrosine.

N-Palmitoyl-L-glutamine is a glutamine derivative, with palmitoyl and glutamine as the primary structures, with low activity (38.8 U mg) as a substrate for the enzyme PmAcy, which is increased by activation at high temperatures and by addition of metal ions.PmAcy (aminoacylase from Paraburkholderia monticola DSM 100849) is an aminoacylase that synthesizes n -acyl amino acids.

L-5-Hydroxytryptophan (L-5-HTP), the immediate precursor in the biosynthesis of SEROTONIN from tryptophan, is used as an antiepileptic and antidepressant.

Cis-ACBD (cis-1-aminocyclobutane-1,3-dicarboxylic acid) is a potent and selective N-methyl-D-aspartate receptor agonist.

Uridine-5-methylamino acetic acid (CMAMU) is a derivative of glycine and uracil with a substituent at position 5 of the uracil ring, and is commonly used to study the synthesis and translation processes of nucleic acids, RNA and tRNA.

L-SelenoMethionine (L-(+)-Selenomethionine) is a naturally occurring amino acid. It promotes cell cycle progression and elevates the expression of the antioxidant enzymes thioredoxin reductase, glutathione reductase.

TAME hydrochloride (Tos-Arg-OMe HCl) is a kind od amino acid derivatives.

DL-Selenomethionine (Seleno-DL-methionine) is a selenium (Se) analogue of methionine in which sulfur is replaced with the trace element selenium. Selenomethionine (SeMet) can incorporate into proteins in place of methionine with no effects on protein structure and function, providing a mechanism for reversible Se storage in organs and tissues.

γ-Glu-Gly (gamma-Glutamylglycine), a γ-glutamyl dipeptide, is a human lipid metabolite with a structure resembling that of GABA (γ-aminobutyric acid). It functions as an antagonist of excitatory amino acids.

Fmoc-Lys(Alloc)-OH is a lysine derivative containing Fmoc protecting group, which can be used for peptide synthesis and drug design.

L-Isoleucine (Ile) is an essential branched-chain aliphatic amino acid found in many proteins. It is an isomer of LEUCINE. It is important in hemoglobin synthesis and regulation of blood sugar and energy levels.

Aceglutamide (N2-Acetylglutamine) is an acetyl derivative of the amino acid L-glutamine, used to improve memory.

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(1H-imidazol-4-yl)propanoic acid is a histidine derivative.

O-Phospho-L-serine (Phosphoserine) is the phosphoric acid ester of serine.

L-Arginine hydrochloride is a nitrogen donor for synthesis of nitric oxide.

Fmoc-L-aspartic acid (Fmoc-Asp-OH) is an aspartic acid derivative.

Fmoc-Aib-OH (Fmoc-alpha-methylalanine) is an alanine acid derivative containing an Fmoc protecting group, which can be used for peptide synthesis and biopharmaceutical design.

Fmoc-Cys(Acm)-OH (Fmoc-S-acetamidomethyl-L-cysteine) is a cysteine derivative.

DL-o-Tyrosine is a metabolite of Phenylalanine and is a precursor in the formation of catecholamines. It is used as biomarkers of protein oxidative damage in β-thalassemia.

DL-Glutamine (2-amino-4-carbamoylbutanoic acid), a non-essential amino acid, exists abundantly throughout the body and is participated in many metabolic processes. It is synthesized from glutamic acid and ammonia, and is the main carrier of nitrogen in the body and is an important energy source for many cells.

Fmoc-Lys-OH (Nα-Fmoc-L-lysine) is a lysine derivative commonly utilized in the synthesis of active compounds.
