| | Azido-PEG4-t-butyl acetate Usage And Synthesis |
| Description | Azido-PEG4-CH2CO2-t-butyl ester is a PEG reagent containing an azide group and a t-butyl protected carboxyl group. The azide group enables Click Chemistry. The protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. t-butyl ester can be deprotected by acidic or basic hydrolysis. The hydrophilic PEG spacer increases solubility in aqueous media. | | Uses | Azido-PEG4-CH2-Boc is a cleavable 4 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. Azido-PEG4-CH2-Boc is also a PEG- and Alkyl/ether-based PROTAC linker that can be used in the synthesis of PROTACs[2]. Azido-PEG4-CH2-Boc is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups. | | IC 50 | PEGs; Alkyl/ether; Cleavable Linker | | References | [1] Shiladitya Sengupta, et al.
