Echinocandin mode of action
WebMechanism of Action Rezafungin is a semi-synthetic echinocandin. Rezafungin inhibits the 1,3-β-D-glucan synthase enzyme complex, which is present in fungal cell walls but not in mammalian cells. This results in inhibition of the formation of 1,3-β-D-glucan, an essential component of the fungal cell wall of many fungi, including WebMar 1, 2003 · It belongs to the echinocandin family, and is a derivative of pneumocandin B o.
