compound introduction
DBCO-PEG5-NHS ester 是一种 PROTAC 连接桥，属于 PEG 类和 Alkyl/ether 类，用于合成一系列 PROTAC 分子。DBCO-PEG5-NHS ester 是一种可降解 (cleavable) 的 ADC 连接桥，用于抗体活性分子结合物 (ADCs) 的合成。DBCO-PEG5-NHS ester 是一种点击化学试剂。它含有 DBCO 基团，可以和含有 Azide 基团的分子发生环张力 (strain) 促进的炔-叠氮环加成反应 (SPAAC)。 DBCO-PEG5-NHS Ester is a PEG derivative containing NHS ester that can react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer increases the water solubility of compounds in aqueous media. DBCO is commonly used for copper-free Click Chemistry reactions due to its high activation energy.
