A Furantaxane with an Unusual 6/8/6/5 Ring System and Potent Tumor MDR Reversal Activity Obtained via Microbial Transformation
摘要:
A furantaxane (4) with an unusual 6/8/6/5 ring system and two hydroxylated products (2, 3) were isolated following the biotransformation of a taxane (1) by Streptomyces griseus. The structures of the isolates were elucidated by spectroscopic analysis. The absolute configuration of 4, which exhibited potent reversal activity in the A549/taxol MDR tumor cell line, was unambiguously deduced by single-crystal X-ray diffraction.
