N-Cbz-L-Leucine (N-[(Phenylmethoxy)carbonyl]-L-leucine) is a leucine derivative, a commonly used amino acid protecting group.

Tyrosylleucine is a dipeptide composed of tyrosine and leucine. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following

Prolylleucine (((Benzyloxy)carbonyl)-L-prolyl-D-leucine) is a dipeptide containing branched-chain amino acids.

N-[(1,1-Dimethylethoxy)carbonyl]-L-leucyl-L-leucine is a useful organic compound for research related to life sciences. The catalog number is T65042 and the CAS number is 73401-65-7.

Cyclo(Pro-Leu) (Cyclo-L-prolyl-L-leucine) is a marine-derived natural product with brine shrimp lethality.

Gamma-Methylleucine (2-Amino-3-tert-butylpropionic acid) is an auxiliary for copper-catalyzed asymmetric Michael reactions.

L-Leucine benzyl ester p-toluenesulfonate salt is a useful organic compound for research related to life sciences. The catalog number is T65805 and the CAS number is 1738-77-8.

Phenylalanylleucine is a bioactive chemical.

Tuna AI acetate is an inhibitor of angiotensin-converting enzyme (ACE) in non-competitive manner derived from tuna muscle.

H-Leu-Leu-OMe . HBr is a dipeptide condensation product of L-leucine methyl ester generated by human monocytes or polymorphonuclear leukocytes. H-Leu-Leu-OMe . HBr induces endolysosomal pathway stress and selectively eliminates lymphocytes with cytotoxic potential.

H-Leu-Leu-Ala-OH, a tripeptide consisting of two L-leucine residues linked to L-alanine via peptide bonds, exhibits antioxidant activities [1].

L-K6L9, a cytolytic peptide comprised of L-isomer leucine and lysine, demonstrates cytotoxicity against both androgen-independent (LNCaP-CL1) and androgen-dependent (22Rv1 and LNCaP) human prostate cancer cells, with LC50 values of 4, 4, and 6 µM, respectively. It also affects non-cancerous cells, including NIH3T3 mouse fibroblasts and OL human foreskin fibroblasts, with LC50s of 7 and 5 µM, respectively. Furthermore, at a concentration of 100 µM, L-K6L9 induces hemolysis in isolated human erythrocytes.

L-Leucyl-L-alanine is a simple dipeptide composed of L-leucine and L-alanine>[1].
