A novel sordarin derivative, moriniafungin (1), containing a 2-hydroxysebacic acid residue linked to C-3' of the sordarose residue of sordarin through a 1,3-dioxolan-4-one ring was isolated from the fungus Morinia pestalozzioides. Isolation of moriniafungin employed a highly specific bioassay consisting of a panel of Saccharomyces cerevisiae strains containing chimeric eEF2 for Candida glabrata, Candida krusei, Candida lusitaniae, Crytpococcus neoformans, and Aspergillus fumigatus as well as wild type and human eEF2. Moriniafungin exhibited an MIC of 6 microg/mL versus Candida albicans and IC(50)'s ranging from 0.9 to 70 microg/mL against a panel of clinically relevant Candida strains. Moriniafungin was shown to inhibit in vitro translation in the chimeric S. cerevisae strains at levels consistent with the observed IC(50). Moriniafungin has the broadest antifungal spectrum and most potent activity of any natural sordarin analog identified to date

Trivial name: moriniafungin
Compound class: glycoside
Methods: 13C NMR, 1H NMR, NMR-2D, IR, HPLC, extraction, optical rotation measurement, column chromatography, cell growth, centrifugation, antifungal activity test, countercurrent chromatography, ESI-FTMS
Biological activity: moriniafungin shows antifungal activity against the ascomycetous yeasts, S. cerevisiae, C. albicans, and C. glabrata, but displays no antifungal activity against the basidiomycetous yeast Cr. neoformans and the ascomycetous yeasts C. parapsilosis, C. krusei, and C. lusitaniae. Moriniafungin has acquired significant activity against the C. krusei chimeric construct, against which sordarin is completely inactive
Comments, role: atom enumeration is according to the Fig. 1 in the paper
