图1. 常见ADC药物使用的细胞毒素载荷(payload) 体外研究结果显示,PBD二聚体对各种癌细胞类型表现出皮摩尔范围内的细胞毒性,这意味着PBD二聚体是迄今为止市售ADC中使用的具有极强肿瘤杀伤效果的细胞毒素payload(如图2所示)8 图2. 不同...
CAS1222490-34-7 PBD-dimer PBD二聚体 ADC抗体简介 接下来由r瑞 x禧小编来为大家介绍——ADC由“抗体”、“接头”和“效应分子”三个主要组件构成。效应分子(payload)原指细胞毒素加上接头部分,现经常和细胞*素混用。其中接头通常还包括和抗体偶联的隔离区(spacer) .化学或酶裂解区、释放效应分子的消除区等。
ADC由“抗体”、“接头”和“效应分子”三个主要组件构成。效应分子(payload)原指细胞毒素加上接头部分,现经常和细胞*素混用。其中接头通常还包括和抗体偶联的隔离区(spacer) .化学或酶裂解区、释放效应分子的消除区等。ADC在抗**领域己经演变成为生物抗体药的主要类别之一。和传统的部分人源化抗体或抗体片段相比,...

We examined 15 ADCs with PBD-dimer payloads and a DAR of 2 and concluded that dose limiting toxicities in animals and in humans are generally related to the payload. Both the payloads and the ADCs had pro-inflammatory responses causing severe toxicities that were at times of low incidence, ...
Study Evaluates Pyrrolobenzodiazepine (PBD)-dimers Containing Disulfide-based Prodrugs as Payloads for Antibody-Drug... Peter Hofland A number of cytotoxic pyrrolobenzodiazepine (PBD) monomers containing various disulfide-based prodrugs were evaluated for their ability to undergo activation (disulfide cleava...
Trastuzumab-PBD, with good efficacy and safety profile. Meanwhile, the PBD analogues could also be used for conjugation to other monoclonal antibodies, to explore the feasibility of the PBD compounds as new ADC payload. 结题摘要 结题摘要基于PBDs类化合物和倍癌霉素类化合物相似的细胞毒性作用机理,...
Payload:ADC Therapeutics公司使用的PBD为二代PBD,其优点在于不依赖于细胞分裂周期,不会使DNA双螺旋扭曲,从而有效避免DNA的修复机制,细胞毒性更佳。临床前结果显示,新一代PBD弹头比目前市场上ADC使用的毒性弹头强100倍,与第一代PBD相比,第二代PBD并非多重耐药蛋白的底物,因此不易产生耐药性。
