产品详情
Tesirine (SG3249) 是一种抗体偶联药物 (ADC) 的吡咯苯并二氮卓 (PBD) 二聚体。Tesirine 结合了抗肿瘤活性和理想的物理化学性质,如良好的疏水性和改进的共轭特性。SG3199 (HY-101161) 是 ADC 有效载荷 Tesirine 的释放弹头成分。SG3199 在一组癌细胞系中保持皮摩尔活性。PBD 二聚体是一种高效的 DNA 小沟交联剂,具有很强的细胞毒性。
生物活性
Tesirine (SG3249) is an antibody-drug conjugate (ADC) pyrrolobenzodiazepine (PBD) dimer payload. Tesirine combines potent antitumor activity with desirable physicochemical properties such as favorable hydrophobicity and improved conjugation characteristics. SG3199 (HY-101161) is the released warhead component of the ADC payload Tesirine. SG3199 retains picomolar activity in a panel of cancer cell lines. PBD dimers are highly efficient DNA minor groove cross-linking agents with potent cytotoxicity.
