摘要: 我们在进行微生物来源的5-脂氧合酶抑制剂的筛选过程中, 得到了一株具有活性的曲霉菌F06Z-509。经过对其发酵产物进行分离纯化, 最终得到三个活性化合物, 分别为F06Z-509-A, B 和 C。通过对它们核磁和质谱数据进行分析, 确定其结构分别与已知化合物butyrolactone II, I和III相同。它们对5-脂氧合酶都表现出较强的抑制活性, IC50值分别为21.43, 22.51和11.83 μg/mL。它们对5-脂氧合酶的抑制活性未见报道。

关键词: 5-脂氧合酶抑制剂, Butyrolactones, 真菌代谢产物

Abstract:

In our ongoing search for new inhibitors of 5-lipoxygenase (5-LOX) from microbial resources, Aspergillus F06Z-509 was found to produce active components. Three active compounds named F06Z-509-A, B and C were obtained and identified as butyrolactone II, I and III by NMR and MS data analyses. They showed inhibitory activity against 5-LOX with IC50 of 21.43, 22.51 and 11.83 μg/mL, respectively. Butyrolactones are shown to be inhibitors of 5-LOX for the first time.

Key words: 5-Lipoxygenase inhibitors, Butyrolactones, Fungal metabolites
