Table 1. Activity of compounds 1 and 2 against T. brucei 427WT and the isometamidium-resistant strain ISMR1.
Compounds | T. b. brucei 427WT | T. b. brucei ISMR1 | Resistance Factor vs. Tb247WT |
---|---|---|---|
EC50 (μM) ± SEM | EC50 (μM) ± SEM | ||
1 | 0.83 ± 0.08a | 105.3 ± 3.2 | 127 *** |
2 | 0. 220 ± 0.002a | 29.0 ± 0.7 | 132 *** |
Isometamidium | 0.016 ± 0.001 | 1464 ± 94 | 92522 *** |
EC50 values are given as mean of at least three independent determinations and SEM. The resistance factor (RF) is the ratio of the EC50 values of the adapted strain and the wild-type control. Statistical significance was determined using a two-tailed unpaired t-test.
aReference (3). Asterisks represent P-values for statistically significant resistance, as calculated using a two-tailed unpaired Student's t-test: ***, P-value <0.0001.
