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].
Mal((3S,3aR,6S,6aR)-Hexahydrofuro[3,2-b]furan-3,6-diamine-PEG12)-β-Glu-PAB-Exatecan (LP1) 是一种用于ADC(抗体偶联药物)的药物-连接体偶联物。它由DNA拓扑异构酶 I 的强效抑制剂Exatecan和连接子Mal((3S,3aR,6S,6aR)-Hexahydrofuro[3,2-b]furan-3,6-diamine-PEG12)-β-Glu-PAB构成,用于制备抗体偶联物AZD0516。
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.
