体外研究 (In Vitro) |
Dxd (Exatecan derivative for ADC) is a potent DNA topoisomerase I inhibitor, with an IC50 of 0.31 μM, used as a conjugated drug of HER2-targeting ADC (DS-8201a). Dxd is cytotoxic to human cancer cell lines of KPL-4, NCI-N87, SK-BR-3, and MDA-MB-468 with IC50s of 1.43 nM-4.07 nM, but the control IgG-ADC (Dxd is the payload) shows no inhibition on the four cell lines (with HER2 expression). DS-8201a (Dxd is the payload) displays significant suppression on the HER2-positive KPL-4, NCI-N87, and SK-BR-3 cell lines, with IC50 values of 26.8, 25.4, and 6.7 ng/mL, respectively, but with no such inhibition on MDA-MB-468 (IC50, >10,000 ng/mL)[1]. 上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods.

体内研究 (In Vivo) |
DS-8201a (Dxd is the payload, 10 mg/kg, i.v.) shows potent antitumor activity in HER2-positive models with KPL4, JIMT-1, and Capan-1 and in HER2 low-expressing ST565 and ST313 models with HER2 IHC 1+/FISH-negative expression[1]. 上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods.

Cell Assay [1] |
Cells are seeded to a 96-well plate at 1,000 cells per well. After overnight incubation, Dxd is added. Cell viability is evaluated after 6 days using a CellTiter-Glo Luminescent Cell Viability Assay. For the detection of HER2 expression in each cell line, cells are incubated on ice for 30 minutes with FITC Mouse IgG1, κ Isotype Control, or anti-HER2/neu FITC. After washing, the labeled cells are analyzed by FACSCalibur. Relative mean fluorescence intensity (rMFI) is calculated[1]. 上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods.
