YNPCVMYL (Thioester: Cys4-Leu8) is a polypeptide chain with a thioester bond in its sequence. Specifically, this bond forms between the fourth amino acid, cysteine (Cys4), and the eighth amino acid, leucine (Leu8).

YNPCVMYL (Thioester: Cys4-Leu8) TFA is a polypeptide chain with the sequence YNPCVMYL. Within this sequence, a thioester bond forms between the fourth amino acid, cysteine (Cys4), and the eighth amino acid, leucine (Leu8), connecting them via a thioester linkage.

E-2078, known chemically as (N-Me-Tyr1,N-Me-Arg7,D-Leu-NHEt8)-Dynorphin A (1-8), is a stable analog of Dynorphin A (1–8) and functions as a kappa opioid receptor (KOR) agonist [1].

D[LEU4,LYS8]-VP TFA is a selective agonist for the vasopressin V1b receptor, with Ki values of 0.16 nM for rat, 0.52 nM for human, and 1.38 nM for mouse V1b receptors. This compound exhibits limited antidiuretic, vasopressor, and oxytocic activities in vitro [1] [2].

Acetyl-(D-Phe2,Lys15,Arg16,Leu27)-VIP(1-7)-GRF(8-27) is a selective antagonist for the vasoactive intestinal peptide 1 (VIP 1) receptor.

Daaccal can be used for relevant research in the life sciences. Its product number is T31173 and CAS number is 103614-06-8.

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.

Boc-D-Leu-OH is a useful organic compound for research related to life sciences. The catalog number is T66581 and the CAS number is 16937-99-8.

TNO211 is a bioactive peptide that functions as a highly soluble fluorogenic substrate for select Matrix Metalloproteinases (MMPs)—specifically MMP-2, 8, 12, 13, and 14. Incorporating a cleavable Gly-Leu bond and an EDANS/DABCYL fluorophore/quencher pair, TNO211 enables sensitive detection of MMP activity through fluorescence assays, with an absorption/emission profile at 340/490 nm. It is particularly effective in analyzing MMPs in culture media from endothelial cells as well as untreated synovial fluid from patients, highlighting its utility in investigations of MMP-associated cellular behaviors, including proliferation, migration (adhesion/dispersion), differentiation, angiogenesis, apoptosis, and host defense.

8-Bromo NAD+ serves as a prodrug for the cyclic ADP-ribose (cADPR) inhibitor, 8-bromo cADPR, undergoing conversion to its active form by the enzyme CD38. At a concentration of 1 mM, it effectively inhibits the rise in intracellular calcium levels and chemotaxis triggered by N-formyl-Met-Leu-Phe (fMLP) in mouse bone marrow-derived neutrophils. Furthermore, when applied at 100 µM, this compound reduces LPS-induced nitrite production and decreases the secretion of TNF-α and IL-2 in mouse primary microglial cells.

Pro-Leu-Gly-NHOH hydrochloride functions as an MMP-8 inhibitor [1].

N-Formyl-Nle-Leu-Phe-Nle-Tyr-Lys TFA (For-Nle-Leu-Phe-Nle-Tyr-Lys-OH (TFA)) (For-Nle-Leu-Phe-Nle-Tyr-Lys-OH TFA) is a formyl peptide receptor (FPR) agonist and a potent chemoattractant for human neutrophils, with its radioiodinated form retaining full biological activity.

Cyclo(L-Leu-L-Trp) is a diketopiperazine metabolite initially derived from Penicillium, exhibiting antibacterial (MICs = 125-1000 µg/ml) and antifungal activities (MICs = 8-64 µg/ml). It also demonstrates antioxidant properties by reducing the production of hydroxy radicals, as evidenced in an electron spin resonance (ESR) spectroscopy assay (IC50 = 1.8 µM). Additionally, Cyclo(L-Leu-L-Trp) has been identified as a bitter compound capable of quickly crossing rat taste cell membranes ex vivo at a 1 mM concentration. Furthermore, it acts as a melatonin receptor agonist in X. laevis melanophores, suppressing cAMP accumulation at a 20 µM concentration, with this effect being negated by the melatonin receptor antagonist luzindole.
