DBCO-NHCO-PEG4-amine 是一种 PROTAC 连接桥，属于 PEG 类。DBCO-NHCO-PEG4-amine 是一种可降解 (cleavable) 的 ADC linker，可用于连接 MMAE (HY-15162) 和抗体 (例如 DBCO-VCpAB MMAE 和 DBCO-TRX MMAE，对 SKBR3 细胞的 EC50 分别为 280 nM 和 22 nM)。 DBCO-PEG4-Amine TFA is a heterobifunctional building block with two reactive terminals. The Dibenzocyclooctyne (DBCO) terminus is useful for copper-free click chemistry. DBCO compounds react with azides without need of Cu(I) catalyst due to the strained nature of alkyne resulting in formation of fast and stable triazole linkage. The amine terminus is useful for reaction with carboxylic acid containing linkers in presence in actiavtors such as EDC or HATU. DBCO-NHCO-PEG4-amine is a PEG-based PROTAC linker can be used in the synthesis of PROTACs. DBCO-NHCO-PEG4-amine is a cleavable ADC linker used to conjugate MMAE (HY-15162) and antibody (e.g., DBCO-VCpAB MMAE and DBCO-TRX MMAE with EC50s of 280 nM and 22 nM in SKBR3 cells, respectively)
