摘要:

对海洋放线菌Actinoplanes sp. M4I6的次生代谢产物进行分离鉴定, 并评价了其生物活性。采用正相硅胶柱色谱、反相C18柱色谱、Sephadex LH-20凝胶柱色谱和高效液相色谱等技术进行分离纯化, 运用核磁共振波谱技术对分离所得化合物进行结构鉴定。对分离得到化合物进行了抗枯草芽孢杆菌(Bacillus subtilis ATCC 6633)和抑制乙酰胆碱酯酶活性评价。共分离得到9个化合物, 经鉴定为(E)-prop-1-enyl-2-hydroxypropanoate(1)、cyclo-(R-Pro-R-Phe)(2)、cyclo-(L-Val-L-Leu)(3)、cyclo-(L-Phe-L-Val)(4)、cyclo-(L-Leu-L-Phe)(5)、lumichrome (6)、2-(4-hydroxyphenyl)ethylacetate(7)、4-hydroxysattabacin(8)、3-hydroxybutan-2-yl 2-phenylacetate (9), 其中化合物1为新天然产物。化合物5689Bacillus subtilis ATCC 6633有一定的抑制活性, 化合物46对乙酰胆碱酯酶有较弱的抑制活性。

Abstract:

The secondary metabolites of marine actinomycete Actinoplanes sp. M4I6 were isolated and identified, moreover their biological activities were evaluated. The compounds were separated and purified by Silica gel, C18, Sephadex LH-20 column chromatography and high performance liquid chromatography (HPLC), and their structures were identified by NMR spectroscopic method. These compounds were evaluated for anti-Bacillus subtilis (ATCC 6633) and inhibition of acetylcholinesterase activity. Nine compounds were separated and identified as (E)-prop-1-enyl-2-hydroxypropanoate(1), cyclo-(R-Pro-R-Phe)(2), cyclo-(L-Val-L-Leu)(3), cyclo-(L-Phe-L-Val)(4), cyclo-(L-Leu-L-Phe) (5), lumichrome (6), 2-(4-hydroxyphenyl)ethylacetate(7), 4-hydroxysattabacin(8), 3-hydroxybutan-2-yl 2-phenylacetate(9), compound 1 is a new natural product. Compounds 5, 6, 8 and 9 showed certain inhibitory activities against Bacillus subtilis(ATCC 6633). Compounds 4 and 6 showed weak inhibitory activities against acetylcholinesterase.
