The present invention relates to an anti-inflammatory use of macrolactin compounds such as macrolactin A, 7-O-malonyl macrolactin A and 7-O-succinyl macrolactin A, which are produced from a novel Bacillus strain of Bacillus polyfermenticus KJS-2 (KCCM10769P). The macrolactin compounds provided by the present invention were confirmed to greatly suppress the expression and formation of inducible nitric oxide synthetase (iNOS) and cyclooxygenase-2 (COX-2) which are proteins related to the formation of inflammatory mediators, and to accordingly inhibit the formation of nitric oxide (NO) and of prostaglandin E2 (PGE2) which are the metabolites of the proteins. In addition, the macrolactin compounds provided by the present invention were confirmed to have excellent effects in inhibiting the formation of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and granulocyte macrophage colony-stimulating factor (GM-CSF), which are pro-inflammatory cytokines. Therefore, the macrolactin compounds produced by the Bacillus polyfermenticus KJS-2 strain according to the present invention can provide excellent anti-inflammatory agents.
本发明涉及大内酯化合物如大内酯A、7-O-丙二酰大内酯A和7-O-琥珀酰大内酯A的抗炎用途,大内酯A和7-O-琥珀酰大内酯A由新型芽孢杆菌菌株聚发酵芽孢杆菌KJS-2(KCCM10769P)产生。经证实,本发明提供的大环内酯化合物能极大地抑制诱导型一氧化氮合成酶(iNOS)和环氧化酶-2(COX-2)的表达和形成(这两种蛋白与炎症介质的形成有关),并相应地抑制一氧化氮(NO)和前列腺素 E2(PGE2)的形成(这两种蛋白的代谢产物)。此外,本发明提供的大环内酯化合物被证实在抑制肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)、白细胞介素-6(IL-6)和粒细胞巨噬细胞集落刺激因子(GM-CSF)这些促炎细胞因子的形成方面具有极佳的效果。因此,根据本发明由多发酵芽孢杆菌 KJS-2 菌株产生的大乳酸化合物可以提供极佳的抗炎剂。
