    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.

    the multidrug resistance of cancer cells. The cytotoxicity (IC(50)) of the compounds was examined against human normal cell line, WI-38, and cancer model cell lines, VA-13 and HepG2. Since compounds 6 and 8 had no cytotoxicity, they were expected to be lead compounds of MDR cancer reversal agents. On the contrary, compounds 3, 5, and 9a showed cell growth inhibitory activity toward VA-13 and/or HepG2
    通过对紫杉云南碱C进行化学修饰和生物转化,获得了一系列在不同位置(如C-2,C-5,C-7,C-9,C-10或C-14)带有较大基团的新一代紫杉类化合物(1 )及其类似物4、5和10。化合物3、5、6、8和9a对MDR 2780AD细胞中的钙黄绿素蓄积具有显着的活性。实际上,最有效的化合物9a在C-14处具有肉桂酰氧基,在C-10处具有羟基,实际上对于MDR 2780AD细胞中抗癌剂长春新碱的细胞蓄积是有效的。6和9a对紫杉醇,阿霉素和长春新碱的增强作用与维拉帕米对MDR 2780AD细胞的增强作用相同。因此,化合物6和9a可以调节癌细胞的多药耐药性。检查了这些化合物对人正常细胞系的细胞毒性(IC(50)),WI-38和癌细胞模型VA-13和HepG2。由于化合物6和8没有细胞毒性,因此它们有望成为MDR癌症逆转剂的先导化合物。相反,化合物3、5和9a在MDR 2780AD中表现出对VA-

    Microbial transformation of two taxadienes (1, 2) was individually investigated with two filamentous fungi, Cunninghamella echinulata CGMCC 3.3400 and Aspergillus niger CGMCC 3.1858, and two actinomycete stains, Streptomyces griseus CACC 200300 and Nocardia purpurea CGMCC 4.1182. A total of 21 products were obtained, 13 of which were new compounds. The reactions that occurred exhibited diversity, including

    Sinenxan A, a taxoid isolated from callus tissue cultures of Taxus yunnanensis was converted into 13-oxo-7,9-dideoxy-2-debenzoyl-2-acetyl-baccatin IV and 7.9-dideoxy-2-debenzoyl-4-deacetyl-baccatin IV, a key framework of 1,7,9-trideoxypaclitaxel. Several special steps in this transformation are worthy of note: (1) deoxygenation by treatment with hypophosphorous acid at C-14 positions (2) a highly regioselective O-deacetylation of taxane:, at C-5 position; and (3) stereoselective reduction of the 13-carbonyl group by transannular assistance from the C-4-hydroxyl.
