产品活性:Trastuzumab deruxtecan (T-DXd; DS-8201a) 是一种抗人表皮生长因子受体 2 (HER2) 抗体-活性分子偶联物 (ADC)。Trastuzumab deruxtecan 由人源化抗 HER2 抗体、酶促裂解的肽接头、拓扑异构酶 I 抑制剂 (毒素成分 Dxd) 组成。Trastuzumab deruxtecan 可用于 HER2 阳性乳腺癌和胃癌的研究。
体外: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]。 MCE尚未独立证实这些方法的准确性。仅供参考。
体内: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]。 MCE尚未独立证实这些方法的准确性。仅供参考。
