Table 3.

CC50 values and selectivity index (SI) of the most active compounds on normal VERO

Test compound (CC50)a (µg/mL) Selectivity index (SI)b
10 250 10
13 125 5

aCC50 is the concentration of compound required to kill 50% of the fibroblast cells

bThe selectivity index (SI) was calculated using the formula, SI = CC50/MIC
