Cytotoxic activity of INA-UV treatment measured on different cancer cell lines by the MTS assay
| Cell line | Human cancer types | IC50 ± SE (μM)* |
| MCF7 | Breast adenocarcinoma | 20.6 ± 8.8 |
| HeLa | Cervical cancer | 11.2 ± 1.7 |
| U251 | Glioma | 15.4 ± 1.0 |
| SKOV-3 | Ovarian carcinoma | 17.6 ± 1.0 |
| SKBR-3 | Breast carcinoma | 7.8 ± 1.5 |
| KB3-1 | Epidermoid carcinoma | 16.0 ± 0.7 |
| KBV1 | Epidermoid carcinoma overexpressing Pgp | 12.3 ± 4.4 |
| 293 | Epithelial cell line from embryonic kidney | 8.6 ± 0.9 |
| 293/MRP1 | Epithelial cell line from embryonic kidney overexpressing MRP1 | 7.3 ± 1.0 |
| SupT1 | T lymphoblastoid | 4.9 ± 0.6 |
* Seven independent measurements were performed and analyzed together. IC50 values were computed by fitting a four-parameter nonlinear regression model with R statistical software [57]. The standard error (SE) represents the 95% confidence interval.
