| Bioactivity | Trastuzumab deruxtecan (DS-8201a) is an anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugate (ADC). Trastuzumab deruxtecan is composed of a humanized anti-HER2 antibody, an enzymatically cleavable peptide-linker, and a topoisomerase I inhibitor. Trastuzumab deruxtecan can be used for the research of HER2-positive breast cancer and gastric cancer[1][2]. |
| Invitro | Trastuzumab deruxtecan（1 pM-10 nM；5 天）抑制 HER2 阳性 KPL-4 细胞的生长，IC50 为 109.7 pM[2]。Trastuzumab deruxtecan（10 nM；5 天）在 HER2 阴性 MDA-MB-468 细胞中表现出旁观者杀伤作用[2]。 |
| In Vivo | Trastuzumab deruxtecan（3 mg/kg；单次静脉注射）在联合接种条件下不仅对 HER2 阳性肿瘤而且对 HER2 阴性肿瘤均显示出抗肿瘤活性[2]。Trastuzumab deruxtecan（10 mg/kg；在第 0 天和第 7 天静脉注射）抑制 EMT6-hHER2 同源小鼠模型中的肿瘤生长[3]。 |
