2015年12月21日 · We demonstrate that site-specific incorporation of pAMF facilitates near complete conjugation of a DBCO-PEG-monomethyl auristatin (DBCO-PEG-MMAF) drug to the tumor-specific, Her2-binding IgG Trastuzumab using strain-promoted azide-alkyne cycloaddn.

Here we describe C lick- A ssisted N CL (CAN), in which peptides are incorporated with traceless “helping hand” lysine linkers that enable addition of dibenzocyclooctyne (DBCO) and azide handles. The resulting strain-promoted alkyne-azide cycloaddition (SPAAC) increases their effective concentration to greatly accelerate ligations.

2020年1月29日 · In this study, we combined a non-site-directed antibody conjugation technique using copper-free click chemistry with ion-exchange chromatography to obtain purified single and double...

2022年11月1日 · We describe practical methods to prepare DOTAGA-DBCO and DFO-DBCO from commercially available starting materials. DOTAGA-DBCO is available in five steps from cyclen with a 33 % overall yield at gram scale.

We report a site-selective cysteine-cyclooctyne conjugation reaction between a seven-residue peptide tag (DBCO-tag, Leu-Cys-Tyr-Pro-Trp-Val-Tyr), at the N or C-terminus of a peptide or protein, and various aza-dibenzocyclooctyne (DBCO) reagents.

The synthesis of 4- [11,12-didehydrodibenzo [b, f]azocin-5 (6 H)-yl]-4-oxobutanoic acid, also known as dibenzoazacyclooctyne (DBCO) or aza-dibenzocyclooctyne (ADIBO), was optimized for large-scale preparations of at least 10 g with an overall yield of 42%.

Successful DBCO-modification was determined by LC-MS (Figure 4(B1,B2) and showed nearly complete conversion by a quantitative shift in the HPLC trace compared to the unmodified peptide (Figure 4(B1)).

2023年2月23日 · DBCO (二苯并环辛炔, Dibenzocyclooctyne) 试剂是用于应变促进的炔叠氮化物环加成（SPAAC）的最具反应性的环炔之一，可实现无铜点击化学。 通常利用多肽中的氨基，巯基或羧基，把DBCO连接到多肽上， DBCO用于无需铜离子催化的叠氮-炔环加成 (SPAAC) 反应，该反应的二级反应动力学常数可达到 1。 DBCO 系列产品包括可用于进一步连接的 DBCO-acid、DBCO-amine、DBCO-PEG-COOH、DBCO-PEG-amine，以及 DBCO 标记的 Biotin、荧光染 …

DBCO-amine is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). DBCO-amine is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.

DBCO-amine 是一种可降解 (cleavable) 的 ADC linker，用于抗体偶联活性分子 (ADCs) 的合成。 DBCO-amine 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-acid 是一种点击化学试剂，可用于合成 ADC linker DBCO-NHS ester (HY-115524 和 HY-115545)，及偶联物 DBCO-PEG-MMAE (HY-111012 和 HY-126690)。 DBCO-acid 含有 DBCO 基团，可以和含有 Azide 基团的分子发生环 …
