Full List of Activity Data of This Antibody-drug Conjugate
Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | half-maximal cytotoxicity Concentration (CC50) | 0.148 nM | High TROP2 expression (TROP2 +++) | ||
| Method Description |
Specifically, human pancreatic cancer cell lines (BxPC - 3, Capan - 1 and PATU - 8988s), breast cancer cell lines (JIMT - 1 and MDA - MB - 468), gastric cancer cell lines (NCI - N87, SNU - 601 and SNU - 620), colon cancer cell lines (HCT15, HT29, DLD - 1, SW480 and COLO205), ovarian cancer cell lines (OVCAR - 3), prostate cancer cell lines (PC - 3 and LNCaP) and Non small cell lung cancer cell lines (NCI - H1781, HCC827, Calu - 1 and Calu - 3). Use MMAE in standalone drug form and SG2057 (cAS #: 260417-62-7, MedKooBiosciences) as PBD dimer included in the ADC prepared according to Example 3. Inoculate each cancer cell line from 500 cells/well to 5000 cells/well into a 96 well plate and culture for 24 hours, followed by treatment with concentrations ranging from 0.256pM to 100nM (5-fold continuous dilution) of ADC1, ADC2, and ADC3 produced according to Example 3, as well as individual drugs MMAE and SG2057. After 144 hours, the number of live cells was quantified using sulforhodamine B (SRB) dye or Cell titrer glo.
