Mal-PEG4-Glu(OH)-NH-m-PEG24 is a polyethylene glycol-based (PEG-based) linker, specifically designed for the synthesis of proteolysis-targeting chimeras (PROTACs)[1].
Mal-PEG4-Glu(TFP ester)-NH-m-PEG24 is a polyethylene glycol (PEG)-based linker essential for the synthesis of proteolysis targeting chimeras (PROTACs)[1].
γ-Glu-Gly TFA, a γ-glutamyl dipeptide, is a human lipid metabolite with a structure resembling GABA (γ-aminobutyric acid). It serves as an excitatory amino acid antagonist [1][2][3].
γ-Glu-Cys is an intermediate in glutathione (GSH) synthesis.1It is formed by ATP-dependent condensation of cysteine and glutamate by γ-glutamylcysteine synthetase. γ-Glu-Cys is also an essential component of phytochelatins, the heavy metal detoxifying enzymes in plants.2
Abz-Ala-Pro-Glu-Glu-Ile-Met-Arg-Arg-Gln-EDDnp is a fluorescence-quenched peptide substrate for human neutrophil elastase (kcat/Km = 531 mM-1s-1). Enzymatic peptide hydrolysis disrupts the Abz:EDDnp donor-acceptor pair allowing fluorescence measurement of Abz (ex = 320 nm; em = 420 nm).
Boc-Glu-OBzl is an amino acid building block.1,2It has been used in the synthesis of peptide-based inhibitors of human caspases and human rhinovirus (HRV) 3C protease that have enzyme inhibitory activityin vitro. 1.Garcia-Calvo, M., Peterson, E.P., Leiting, B., et al.Inhibition of human caspases by peptide-based and macromolecular inhibitorsJ.

Fmoc-Ala-Glu-Asn-Lys-NH2 is a peptide inhibitor that selectively targets asparagine endopeptidase (AEP) and inhibits the cleavage of amyloid precursor protein (APP). AEP, a pH-controlled cysteine proteinase, plays a crucial role in the proteolytic processing of APP, and its activity is enhanced during the aging process [1].
SuO-Glu-Val-Cit-PAB-MMAE is a chemical compound comprising a cleavable ADC linker, SuO-Glu-Val-Cit-PAB, and a potent tubulin inhibitor known as MMAE. It is utilized in the synthesis of antibody-drug conjugates (ADCs).
