Structural Elucidation of YM-75518, A Novel Antifungal Antibiotic Isolated from Pseudomonas sp. Q38009

An antifungal antibiotic, YM-75518, was isolated from the fermentation broth of Pseudomonas sp. Q38009. Structural elucidation of YM-75518 was accomplished through extensive 2D NMR spectroscopy including 15N- 1H HMQC and 15N-HMBC at natural abundance. YM-75518 consisted of a unique 15-membered macro...

Summary:An antifungal antibiotic, YM-75518, was isolated from the fermentation broth of Pseudomonas sp. Q38009. Structural elucidation of YM-75518 was accomplished through extensive 2D NMR spectroscopy including 15N- 1H HMQC and 15N-HMBC at natural abundance. YM-75518 consisted of a unique 15-membered macrolactone ring and a methoxy imino structure. © 1997 Elsevier Science Ltd.
