Outline of Final Research Achievements |
The in vivo-mimic assay system using silkworm larvae was performed as the primary screening tool to discover antifungal antibiotics against Candida albicans. 9,500 Microbial cultures were screened in this in vivo-mimic assay system, resulting that five known compounds showing a therapeutic effect were identified. At the same time, in the course of screening for amphotericin B potentiators of microbial origins, four new compounds, designated shodoamides A to D, were isolated from the culture broth of unidentified fungal strain BF-0158. Furthermore, stereochemistries, antifungal activities and mode of action of new antifungal antibiotics, simplifungin and valsafungins A and B, were also elucidated.
