natural antifungal drugs

in our search for natural products with a broad spectrum of antifungal activity as lead compounds for novel treatments for mycoses, we have isolated echinocandin-type lipopeptide fr901379 and lipopeptidolactone fr901469, as novel water-soluble antifungal agents that inhibit the synthesis of 1,3-î²-glucan, a key component of the fungal cell wall. the main thrust of our work to date has been replacement of the highly flexible lipophilic side chains of the natural products with a view to reducing the hemolytic potential associated with these compounds, and to enhance chemical stability and/or in vivo antifungal efficacy.




micafungin is currently in phase iii clinical trials worldwide as a parenteral agent for various mycoses, and a new drug application (nda) was recently filed in japan. sciencedirect â® is a registered trademark of elsevier b.v.
