Abstract:
:Penicillium digitatum, as well as five other citrus pathogenic species, (Penicillium ulaiense Link, Geotrichum citri Link, Botrytis cinerea P. Micheli ex Pers., Lasiodiplodia theobromae (Pat.) Griffon & Maubl., and Phomopsis citri (teleomorph Diaporthe citri)) were observed to convert 6',7'-epoxybergamottin (1) into 6',7'-dihydroxybergamottin (2), bergaptol (3), and an opened lactone ring metabolite 6,7-furano-5-(6',7'-dihydroxy geranyloxy)-2-hydroxy-hydrocoumaric acid (4). Metabolism of 2 by these fungi also proceeded to 4. The structure of 4 was established by high resolution mass spectrometry and (1)H and (13)C NMR techniques. The inhibitory activity of 4 towards human intestinal cytochrome P450 3A4 (CYP3A4) was greatly decreased (IC(50) >172.0 μM) compared to 2 (IC(50)=0.81 μM).
