Emeguisin A is a depsidone fungal metabolite originally isolated fromE. unguis.1It is active against the bacteriaS. aureusand methicillin-resistantS. aureus(MRSA; MIC = 0.5 μg ml for both), the fungusC. neoformans(MIC = 0.5 μg ml), and the protozoanP. falciparum(IC50= 2.2 μM).2 1.Kawahara, N., Nozawa, K., Nakajima, S., et al.Isolation and structures of novel fungal depsidones, emeguisins A, B, and C, from Emericella unguisJ.
