(7), from the ethyl acetate extract of the culture of the marine sponge-associated fungus Neosartorya glabra KUFA 0702. The structures of the new compounds were established based on extensive 1D and 2D spectral analysis. X-ray analysis was also used to confirm the relative configuration of the amino acid constituents of sartoryglabramide A (5), and the absolute stereochemistry of the amino acid constituents
分离出两个新的环四肽,sartoryglabramides A(5)和B(6)和一个新的法伐他汀A(8)类似物,以及六个已知化合物,包括ergosta-4、6、8(14),22-tetraen-3 -一,麦角固醇5,8-内过氧化物,己二酸,天青素(1),(3R)-3-(1H-吲哚-3-基甲基)-3,4-二氢-1H-1,4-苯并二氮杂-2, 5-二酮(2),高ak酰胺(3),(11aR)-2,3-二氢-1H-吡咯并[2,1-c] [1,4]苯并二氮杂5,11(10H,11aH)-二酮( 4)和氟尿嘧啶A(7),是从海洋海绵相关真菌Neosartorya glabra KUFA 0702的乙酸乙酯提取物中提取的。新化合物的结构是根据广泛的1D和2D光谱分析建立的。X射线分析还用于确定sartoryglabramide A(5)氨基酸成分的相对构型,并通过与d-和l-氨基酸标准品共同进样,通过手
