19-trihydroxystemarane (13). 19-N,N-Dimethylcarbamoxy-13-hydroxystemarane (14) was not transformed by the fungus. Stemodin (1) was incubated with Whetzelinia sclerotiorum ATCC 18687 to produce 2alpha,7beta,13-trihydroxystemodane (6) and 2alpha,11beta,13-trihydroxystemodane (4). Stemodinone (7) was converted to 7beta,13-dihydroxystemodan-2-one (10). Compounds 2, 4, 9, 10, 12 and 13 have not been previously
用毛霉属植物 ATCC 4740 孵育大黄素 (1) 导致形成 2alpha,6beta,13-trihydroxystemodane (2)、2alpha,3beta,13-trihydroxystemodane (3)、2alpha,11beta,13-trihydroxystemodane (4) 和 2alpha ,13,14-trihydroxystemodane (5),而甾体酮 (7) 提供 6alpha,13-dihydroxystemodan-2-one (8) 和 6alpha,12alpha,13-trihydroxystemodan-2-one (9)。从 Stemarin (11) 的生物转化中获得的代谢物是 8,13,19-trihydroxystemarane (12) 和 2alpha,13,19-trihydroxystemarane (13)。19-N,
