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].

Various indicated cancer lines were seeded at low density and treated with titrated doses of DXd (1-10000 nM) or DM1, with DMSO solvent used as control treatment group. Cells were cultured for 5 days or until control groups reached >90% confluency. Cell viability and drug induced toxicity were assessed by cellular ATP quantification using using CellTiter-Glo Luminescent Cell Viability Assay following manufacturer’s protocol.

Protocol
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].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice[1]
Briefly, each cell suspension or tumor fragment is inoculated subcutaneously into specific pathogen-free female nude mice. When the tumor has grown to an appropriate volume, the tumor-bearing mice are randomized into treatment and control groups based on the tumor volumes, and dosing is initiated on day 0. Each substance (DS-8201a, 1 or 10 mg/kg, i.v.; Dxd is the payload) is administered intravenously to the mice. Tumor growth inhibition (TGI, %) is calculated[1].
