抗体-药物偶联物(ADC)接头连接器和偶联策略介绍
发布时间:2021-04-07     作者:axc   分享到:

抗体-药物偶联物(ADC)由三个基本原件组成:特异性单克隆抗体(mAb),被称为载荷的细胞*性小分子,以及连接mAb和载荷的化学连接器。与细胞表面上的相应抗原结合后,将ADC/抗原复合物内化,然后释放载荷,从而导致细胞*性。

当前在ADC中使用的链接器分为两大类:可裂解的和不可裂解的链接器。

可裂解的链接器对几种细胞内条件。例如:缬氨酸-瓜氨酸(Val-Cit)和缬氨酸-丙氨酸(Val-Ala)。

不可裂解链接器:硫醚链接器,N-琥珀酰亚胺基-4-(N-马来酰亚胺甲基)环己烷-1-甲酸SMCC)和马来酰亚胺基己酰基(MC)。
