ADCs(antibody-drugconjugates)技术是通过linker将单抗和药物分子偶联在一起,利用抗体的特异性靶向运输药物分子到靶组织发挥作用,降低药物的系统性毒副作用,提高药物治疗窗和拓展抗体治疗潜能[1]。血液中循环的ADC与靶抗原结合后,通过网格蛋白介导的内吞作用被内化(图1)[2]。内化的复合物随后进入内体-溶酶体途径,大多...
背景 抗体-药物偶联物(Antibody–drug conjugates ADCs)药物是由抗体(antibodies)通过连接子(linkers)结合细胞毒性药物(弹头 Payload/Warhead)组成。ADCs药物在循环中需要处于稳定状态,可以被认为是一种前药(prodrug),药物结合靶点后,内吞入细胞,通常在溶酶体释放细胞毒药物,进行肿瘤细胞杀伤作用。由于抗体靶向性强,携带...
这种技术叫TDCs(THIOMAB drug conjugates TDCs),这样可以生成接近一致的药物抗体比(Drug‐to‐Antibody Ratio DAR)为2或者4的ADC药物,而不用破坏抗体上的二硫键(半胱氨酸桥),不幸的是,第一个TDCs药物在循环中也存在较高的解偶联率,这是由于马来酸亚胺(maleimide)可以与血浆中的白蛋白、自由半胱氨酸、谷胱甘肽发生...

Antibody–drug conjugates come of age in oncology Article12 June 2023 Introduction Cancer has become the second greatest global health threat, accounting for approximately 10.0 million deaths from cancer occurred in 2020.1Cytotoxic agents based chemotherapy has been the main approach for the treatment of...
而抗体-药物偶联物(Antibody–Drug Conjugates ADCs)药物可以弥补这些缺点。ADCs药物是由抗体(antibodies)通过连接子(linkers)结合细胞毒性药物(弹头 Payload/Warhead)组成。ADCs药物在循环中需要处于稳定状态,可以被认为是一种前药(prodrug),药物结合靶点后,内吞入细胞,通常在溶酶体释放细胞毒药物,进行肿瘤细胞杀伤作用。
Antibody–Drug Conjugates The concept of delivering cytotoxic payloads to specific targets using the high affinity, specificity, and long half-life of antibodies has been around for several decades. Early attempts were hampered by the instability of linkers, immunogenic potential, and inappropriate spec...
Antibody-Drug Conjugates have demonstrated their ability to deliver cytotoxic small-molecule drugs through a selective and targeted mechanism in the fight against cancer. In recent years, ADCs have entered almost 600 clinical trials with more than 60 distinct ADC molecules currently under development. ...
