Enfumafungin, a triterpene glycoside, was extracted from fungus Hormonema carpetanum extract. Enfumafungin is an antifungal compound that acts on the fungal cell wall as a (1,3)-beta-D-glucan synthase inhibitor. Enfumafungin is specific for yeasts and fungi (except Cryptococcus) and does not suppress the growth of Bacillus subtilis.

Biological Activity

Targets	(1,3)-beta-D-glucan synthase[1]
ln Vitro	Enfumafungin has less than 0.5 μg/mL minimum inhibitory concentration (MIC) against Aspergillus and Candida (24–48 hours) [1]
ln Vivo	In mouse kidneys, Enfumafungin (50–200 mg/kg; i.p. twice daily for two days) decreases the amount of C. albicans colonies with an ED90 of 90 mg/kg[1].

Additional Infomation	Enfumafungin is a triterpene glycoside and hemiacetal isolated from a fermentation of Hormonema sp. and which specifically inhibits glucan synthesis in fungal cells. It has a role as an antifungal agent. It is a triterpenoid saponin, a monosaccharide derivative and a lactol. Enfumafungin has been reported in Hormonema with data available.

Solubility Data

Solubility (In Vitro)

DMSO : 100 mg/mL (141.07 mM)

Solubility (In Vivo)

Solubility in Formulation 1: ≥ 2.5 mg/mL (3.53 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (3.53 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.5 mg/mL (3.53 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.)

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
