  Biotransformation of Cycloartane-Type Triterpenes by the Fungus Glomerella fusarioides

  摘要：

  Biotransformation of three cycloartane-type triterpenes, cycloartenol (1), 24-methylenecycloartanol (2), and cycloartenone (3), by the fungus Glomerella fusarioides was studied. Compound 1 was converted to 3, cycloart-25-ene-3 beta, 24-diol (4), and cycloartane-3 beta, 24,25-triol (5). Compound 2 was metabolized to cycloeucalenol (6) and two new compounds, 24-methylcycloartane-3 beta,24,24(1)-triol (7) and 24(1)-methoxy-24-methylcycloartane-3 beta, 24-diol (8). Compound 3 was converted into two new metabolites, 4 alpha,4 beta,14 alpha-trimethyl-9 beta, 19-cyclopregnane-3,20-dione (9) and 25-hydroxy-24-methoxycycloartan-3-one (14), and four known compounds, viz., cycloartane-3,24-dione (10), 24-hydroxycycloart-25-en-3-one (11), (23E)-25-hydroxycycloart-23-en-3-one (12), and 24,25-dihydroxycycloartan-3-one (13). The structures of four new metabolites, 7, 8, 9, and 14, were established by spectroscopic methods.
