L-Leucine ((S)-Leucine) is one of nine essential amino acids in humans (provided by food), L-Leucine is important for protein synthesis and many metabolic functions. L-Leucine contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. L-Leucine also prevents breakdown of muscle proteins after trauma or severe stress and may be beneficial for individuals with phenylketonuria. L-Leucine is available in many foods and deficiency is rare.

D-Leucine ((R)-Leucine) potently terminates seizures even after the onset of seizure activity. D-leucine reduces long-term potentiation but had no effect on basal synaptic transmission in vitro.

N-Acetylleucine belongs to the class of organic compounds known as leucine and derivatives. Leucine and derivatives are compounds containing leucine or a derivative thereof resulting from reaction of leucine at the amino group or the carboxy group, or fro

L-Alanyl-L-leucine (H-Ala-Leu-OH) is a dipeptide compound that is involved in protein synthesis.

N-Benzoyl-L-Leucine is a useful organic compound for research related to life sciences and the catalog number is T131571.

Glycyl-L-leucine (Gly-Leu) is a substrate for the assay of glycyl-L-leucine dipeptidase.

N-Cholyl-L-leucine is a bile acid amidate. It has been found in fecal samples from extremely premature infants with mild or severe brain injuries. N-Cholyl-L-leucine has been used as a standard for the detection of endogenous bile acid amidates in human plasma and fecal samples.

Fructose-leucine (Fru-Leu) is an Amadori compound that can be detected in tobacco and serves as an aroma precursor formed during the initial stages of the Maillard reaction.

Venuloside A (ESK246), a monoprostane glycoside from Pittosporum venulosum, is a LAT3 inhibitor and a leucine uptake inhibitor that inhibits the transporter of leucine through LAT3, and may be used in the study of prostate cancer.

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.

Bestatin (Ubenimex) competitively inhibits many aminopeptidases, including B, N and leucine aminopeptidases. Ubenimex is a microbial metabolite and dipeptide with potential immunomodulatory and antitumor activities. Aminopeptidases has been implicated in the process of cell adhesion and invasion of tumor cells. Therefore, inhibiting aminopeptidases may partially attribute to the antitumor effect of ubenimex. This agent also activates T lymphocyte, macrophage, and bone marrow stem cell as well as stimulates the release of interleukin-1 and -2, thus further enhances its antitumor activity.

L-Norleucine ((S)-Norleucine) is an isomer of leucine, specifically affects protein synthesis in skeletal muscle, and has antivirus activity.

Methylglutaric acid is a leucine metabolite. A large amount of methylglutaric acid is identified in urine of patients with deficiency of 3-methylglutaconyl coenzyme A hydratase (PMID 6181239 ). Methylglutaric acid is also found to be associated with 3-hyd

Leu-Leu-OH is a derivative dipeptide of leucine that can be used to study the function of the double leucine motif, is present as a metabolite in the human body, and is also detected in certain bacteria (e.g. Mycoplasma genitalium).

N-Isovaleroylglycine (Isovaleroylglycine) is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases, the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine < -- > CoA + N-acylglycine. N-Isovaleroylglycine is a byproduct of the catabolism of the amino acid leucine. Accumulation of N-Isovaleroylglycine occurs in Isovaleric Acidemia (IVA).

3-Amino-4-methylpentanoic acid (DL-Homovaline) is a beta-amino acid that is pentanoic acid substituted at positions 3 and 4 by amino and methyl groups respectively. It has a role as a human metabolite.

L-Leucyl-L-alanine, a simple dipeptide, consists of L-leucine and L-alanine>[1].

Enocyanin, an anthocyanin extracted from grapes, exhibits inhibitory effects on leucine aminopeptidase, acid phosphatase, γ-glutamyl transpeptidase, and esterase activity.

Actinonin ((-)-Actinonin) is a naturally occurring antibacterial agent produced by Actinomyces and a potent reversible peptide deformylase (PDF) inhibitor with a Ki of 0.28 nM. It also induces apoptosis and inhibits aminopeptidase M, aminopeptidase N, and leucine aminopeptidase, as well as MMP-1, MMP-3, MMP-8, MMP-9, and meprin α with Ki values of 300 nM, 1,700 nM, 190 nM, 330 nM, and 20 nM, respectively. Actinonin exhibits antiproliferative and antitumor activities [1][2][3][4][5].

Isovalerylcarnitine (3-methylbutyrylcarnitine) is a small molecule compound produced by the catabolism of L-leucine and the accumulation of isovaleric acid. Isovalerylcarnitine is also a selective and effective calpain activator that can promote cell apoptosis. Isovalerylcarnitine is related to isovaleric acidemia and can be used as a marker of isovaleric acidemia.

2,3-dihydroxy-3-methylbutanoic acid is a natural metabolite of the branched-chain amino acid leucine.
