dbco nhs ester 2

DBCO-NHS ester 2 is a cleavable linker employed in the synthesis of antibody-drug conjugates (ADCs). It is a Dibenzylcyclooctyne (DBCO) derivative specifically designed for application in copper-free click chemistry [1].

DBCO-NHCO-PEG2-NHS ester, a PEG-based PROTAC linker, enables the synthesis of PROTACs[1].

DBCO-NH-PEG7-C2-NHS ester is a polyethylene glycol (PEG) derived linker that possesses a terminal DBCO moiety. It functions as an N-hydroxysuccinimide (NHS) ester, making it suitable for the efficient synthesis of proteolysis-targeting chimeras (PROTACs)[1].

DBCO-PEG2-NHS 酯是一种配备NHS酯的聚乙二醇(PEG)点击化学试剂，具备叠氮基团，可于中性或微碱性环境下与伯胺（例如赖氨酸残基侧链或氨基硅烷包被表面）实现特异性高效的共价键合成。其聚乙二醇间隔臂的亲水性显著增强了水溶性，并提供灵活长链结构以极大降低空间位阻，优化了连接效率。主要应用于无铜点击化学反应中。产品为试剂级，仅限研究使用。

DBCO-NHCO-PEG4-NHS ester ester is a MMP-2- and cathepsin B- (CatB) cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1].

DBCO-NHS ester 3 (Compound 12) is a cleavable linker utilized in the synthesis of antibody-drug conjugate (ADC). It is a derivative of Dibenzylcyclooctyne (DBCO) resulting from the activation of N-hydroxysuccinimide by the carboxylic acid moiety of both methyl-oxanorbornadiene (MeOND) and dibenzoazacyclooctyne (DIBAC)[1][2].

N-DBCO-N-bis(PEG2-C2-NHS ester)是一种PEG类的PROTAC linker，可用于合成 PROTAC 分子，同时含有DBCO基团，可以和Azide基团发生点击化学反应。
