抗体偶联药物“ADC”作用机制

ADCs是单克隆抗体和细胞分子的偶联物,兼具抗体的较高选择性、较好的稳定性及药代动力学特征和细胞分子的高*性。

ADCs可分为三部分: 单克隆抗体( monocl onal anti bodi esmAbs) 、细胞*分子( warhead or payl oad) 和连接基( 1i nker)

ADCs对细胞的作用机制

ADCs以静脉注射的方式进入血液循环, 能避免被胃酸和蛋白水解酶破坏。 通过血液循环进入**组织后, 与**细胞表面的抗原结合,在受体介导下通过网格蛋白( clathrin) 的牵引发生细胞内吞, 形成核内体,氢离子流入核内体中形成酸性环境, 有利于新生的Fc受体与ADCsmAbs部分结合, 其中部分ADCsFcRns结合后被排出细胞外, 在碱性环境下, 释放出ADCs, 重新进入体循环,随后核内体与溶酶体发生融合, 未被排出细胞外的ADCs在溶酶体的降解下,释放细胞分子到细胞质中。 细胞分子与DNA、微管蛋白等结合后, 影响其复制或有丝分裂, 导致细胞凋亡。
