In this paper, the microbial transformation of resibufogenin (1) by Curvularia lunata AS 3.4381 was investigated, and four transformed products were isolated and characterized as 3-epi-resibufogenin (2), 12α-hydroxy-3-epi-resibufogenin (3), 12-oxo-16β-hydroxy-3-epi-resibufogenin (4), and 12β,15-epoxy-3-epi-bufalin-14,15-ene (5). Among them, 4 and 5 are new compounds, and isomerization, hydroxylation
本文研究了Curvularia lunata AS 3.4381对Resibufogenin (1)的微生物转化,分离了四个转化产物,并将其表征为3- Epi- Resibufogenin(2),12α-hydroxy-3- epi - Resibufogenin(3)。 ,12-oxo-16β-羟基-3 - epi - resibufogenin(4)和12β,15-epoxy-3- epi -bufalin-14,15-ene(5)。其中4和5是新的化合物,在微生物转化过程中观察到异构化,羟基化和氧化反应。另外,还研究了转化产物的细胞毒性(2 – 5)。
