A novel angiogenesis inhibitor, 5-demethoxyfumagillol (1), was obtained by isolation, purification and saponification of cultured broth of Aspergillus fumigatus. The structure was assigned as (3R,4R,6R)-4-[(2R,3R)-2-methyl-3-(3-methyl-but-2-enyl)-oxiranyl]-1-oxa-spiro[2,5]octan-6-ol (1) by spectroscopic analysis and confirmed by independent synthesis from fumagillol (3). In addition, 6-O-(chloroacetylcarbamoyl)-5-demethoxyfumagillol (7) showed a potential anti-angiogenic activity in CAPE cells in vitro.
通过分离、纯化和皂化烟曲霉的培养液,获得了一种新型血管生成抑制剂--5-去甲氧基烟曲霉醇(1)。通过光谱分析,其结构被归类为 (3R,4R,6R)-4-[(2R,3R)-2-甲基-3-(3-甲基-丁-2-烯基)-环氧乙烷基]-1-氧杂螺[2,5]辛烷-6-醇 (1),并通过与烟曲霉醇 (3) 的独立合成得到证实。此外,6-O-(氯乙酰氨基甲酰基)-5-去甲氧基烟酰醇(7)在体外 CAPE 细胞中显示出潜在的抗血管生成活性。
