Numerous antibody-drug conjugate (ADC) linker technologies exist for the synthesis of ADCs with drug-to-antibody ratios (DARs) being an even integer (typically 2, 4 or 8). However, ADCs with odd-integer DARs are significantly harder to synthesise. Here, we report the synthesis of ADCs loaded with a single warhead, using TetraDVP linkers which simultaneously re-bridge all four interchain disulfides of an IgG1 antibody.
存在许多抗体药物偶联物 (ADC) 连接子技术，可用于合成药物抗体比 (DAR) 为偶数整数（通常为 2、4 或 8）的 ADC。然而，奇数整数 DAR 的 ADC 更难合成。在这里，我们报告了使用 TetraDVP 接头合成负载单个弹头的 ADC 的方法，该接头可同时重新桥接 IgG1 抗体的所有四个链间二硫键。
