Molecule	Description
Synonyms: trastuzumab deruxtecan enhertu DS-8201a fam-trastuzumab deruxtecan-nxki	Fam-trastuzumab deruxtecan-nxki is a HER2-directed antibody-drug conjugate. The antibody is a humanized anti-HER2 IgG1. The small molecule, DXd, is a topoisomerase I inhibitor attached to the antibody by a cleavable linker. Following binding to HER2 on tumor cells, fam-trastuzumab deruxtecan-nxki undergoes internalization and intracellular linker cleavage by lysosomal enzymes. Upon release, the membrane-permeable DXd causes DNA damage and apoptotic cell death. Molecular weight: Formula: CLOGP: LIPINSKI: None HAC: None HDO: None TPSA: ALOGS: ROTB: None
