In pairwise combination studies, AZD5847 exerts additivity with known TB drugs
Drug combination | MIC (μg/ml) |
ΣFICa | |
---|---|---|---|
Alone | Combinationb | ||
AZD5847 | 0.5 | 0.5 | 1.13 |
Isoniazid | 0.03 | 0.004 | |
AZD5847 | 0.5 | 0.125 | 0.8 |
Rifampin | 0.015 | 0.008 | |
AZD5847 | 0.5 | 0.5 | 1.12 |
Ethambutol | 1 | 0.125 | |
AZD5847 | 0.5 | 0.5 | 1.24 |
Streptomycin | 0.25 | 0.06 | |
AZD5847 | 0.5 | 0.5 | 1.06 |
Moxifloxacin | 0.125 | 0.008 |
A ΣFIC (fractional inhibitory concentration [FIC] index) value of ≤0.5 denotes synergy, one of ≥4.0 denotes antagonism, and values in between denote additivity.
The MIC in the combination was determined using a checkerboard method.
