Ibrexafungerp citrate is a triterpenoid antifungal agent that inhibits the synthesis of 1,3-β-D-glucan in fungal cell walls, and although its functional outcome is similar to echinocandins, it binds to a distinct site on the glucan synthase enzyme, resulting in limited cross-resistance. Ibrexafungerp citrate exhibit concentration-dependent fungicidal activity against Candida species and retaining strong in vitro efficacy against the majority of fluconazole-resistant strains, supporting its use in antifungal resistance and drug development research.

| In vitro | In fungal susceptibility assays, Ibrexafungerp citrate acted as a β-1,3-glucan synthase inhibitor, disrupting cell wall integrity. It exhibited a minimum inhibitory concentration (MIC50) of 0.5 μg/mL against various Candida species, including multidrug-resistant Candida auris, resulting in broad-spectrum fungicidal activity [1]. |

DMSO
| |||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
