    MedChemExpress posaconazole
    Summary of drug interaction for the combination of BA and azoles. (A) Species–specific summary of interactions between BA–azole combinations and pathogenic fungi. (B) Azole–specific summary of interactions between BA–azole combinations and pathogenic fungi. (C) Isobologram analysis of the synergistic interaction between BA and POS. The X-axis represents normalized POS concentration, and the Y-axis represents normalized BA concentration. Normalized concentration was calculated as the MIC of the drug in combination divided by the MIC of the drug alone. The solid diagonal line represents the theoretical additive effect based on the Loewe additivity model. The upper and lower dashed lines indicate the 95% confidence intervals of the additive line. Each symbol corresponds to a different clinical isolate. Data points located below the lower 95% confidence line indicate synergistic activity. S, synergy (FICI≤0.5); I, indifference (FICI from >0.5 to ≤4); A, antagonism (FICI of >4); BA, betulinic acid; ITR, itraconazole; VOR, voriconazole; POS, <t>posaconazole;</t> FLC, fluconazole. The synergism rate was calculated by dividing the number of strains exhibiting synergism by the total number of strains tested.

(B) Azole–specific summary of interactions between BA–azole combinations and pathogenic fungi. (C) Isobologram analysis of the synergistic interaction between BA and POS. The X-axis represents normalized POS concentration, and the Y-axis represents normalized BA concentration. Normalized concentration was calculated as the MIC of the drug in combination divided by the MIC of the drug alone. The solid diagonal line represents the theoretical additive effect based on the Loewe additivity model. The upper and lower dashed lines indicate the 95% confidence intervals of the additive line. Each symbol corresponds to a different clinical isolate. Data points located below the lower 95% confidence line indicate synergistic activity.
