Table 2.

Cytotoxic concentration (CC₅₀), inhibitory concentration (IC₅₀) and selectivity index (SI) of isenolic^® formulations.

Isenolic^® formulation	CC₅₀ (µg/ml)^a	IC₅₀ (µg/ml)^a	S.I.
4% EA	218.2 ± 8.9	171.4 ± 13.3	1.3
8% EA	149.7 ± 2.1***	65.5 ± 4.8*	2.3

^{^a}

CC₅₀ and IC₅₀ values are expressed as mean ± SEM of at least two independent assays and were interpolated from non-linear regression analysis. Statistical differences of CC₅₀ and IC₅₀ values comparing 4% and 8% formulations were evaluate by Student's t-test *P < 0.05 vs 4% EA; ***P < 0.001 vs 4% EA.
