IC50 (nanograms per milliliter) of cytotoxic agents
| Cell line | Taxol | SS1P | ATFP |
|---|---|---|---|
| A431/K5 | 4 | 0.4 | 0.3 |
| KB-3–1 | 3 | 5 | 0.4 |
| KB-8–5 | 30 | 3 | 0.4 |
The calculation of IC50 is based on the in vitro cytotoxicity assays of these drugs on several cell lines with the WST-8 assay.
