生物活性

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

体外研究

Trastuzumab deruxtecan (1 pM-10 nM; 5 days) inhibits the growth of HER2‐positive KPL‐4 cells, with an IC50 of 109.7 pM.
Trastuzumab deruxtecan (10 nM; 5 days) shows bystander killing effects in HER2‐negative MDA‐MB‐468 cells.

Cell Viability Assay

Cell Line: KPL‐4 and MDA‐MB‐468 cells
Concentration: 1, 10, 100, 1000, 10000 pM
Incubation Time: 5 days
Result: Killed both HER2‐positive KPL‐4 cells and HER2‐negative MDA‐MB‐468 cells.
体内研究

Trastuzumab deruxtecan (3 mg/kg; a single i.v.) shows antitumor activity against not only HER2‐positive tumors but also HER2‐negative tumors under the co‐inoculated condition.
Trastuzumab deruxtecan (10 mg/kg; i.v. on days 0 and 7) inhibits the tumor growth in in EMT6-hHER2 syngeneic mouse model.

Animal Model: Female BALB/c nude mice injected with NCI‐N87 and MDA‐MB‐468‐Luc cells
Dosage: 3 mg/kg
Administration: A single i.v.
Result: Almost all of the HER2‐positive and HER‐negative cells disappeared and there were little or no cancer cells remaining in the tumors.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
