Enfumafungin, a triterpene glycoside, is isolated from extracts derived from an endophytic species of Hormonema. Enfumafungin is an antifungal compound that is acting on the fungal cell wall, as the (1,3)-beta-D-glucan synthase inhibitor. Enfumafungin is specific for yeasts and fungi (excluding Cryptococcus) and does not inhibit the growth of Bacillus subtilis^[1][2].

(1,3)-beta-D-glucan synthase^[1]

Enfumafungin (24-48 h) has MICs of less than 0.5 μg/mL against the Candida and Aspergillus species tested and it is inactive against Cryptococcus, including the decapsulated form (MY2062)^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Enfumafungin (50-200 mg/kg; i.p. twice daily for 2 days) produces a significant decrease in the number of c.f.u. in kidneys of mice challenged with C. albicans, with an ED₉₀ of 90 mg/kg^[1].
