In Vitro Inhibitory and Cytotoxic Activity of MFM 501, a Novel Codonopsinine Derivative, against Methicillin-Resistant Staphylococcus aureus Clinical Isolates

Table 3

Cytotoxicity and SI values of MFM 501 against three normal cell lines.

Cell linesIC50SI (IC50/MIC*)

Vero>62519.97
WRL-68>62519.97
3T3>62519.97

MIC values of 31.3 µg/mL were chosen to calculate the selectivity index (SI) value.
