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, a topoisomerase I inhibitor (a toxin component of Dxd). Trastuzumab deruxtecan can be used for the research of HER2-positive breast cancer and gastric cancer.

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。< br/> 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。
