The structures and the chemical nature of a novel gastroprotective substance AI-77-B (1) and its analogues AI-77-C (2), D (3), F (4) and G (5), which are produced by Bacillus pumilus AI-77, are described. The structure of 1 was confirmed to be 6-[[1(S)-(3(S), 4-dihydro-8-hydroxy-1-oxo-1H-2-benzopyran-3-yl)-3-methylbutyl]amino]-4(S),5(S)-dihydroxy-6-oxo-3(S)-aminohexanoic acid by X-ray in combination
新型胃保护物质AI-77-B(1)及其类似物AI-77-C(2),D(3),F(4)和G(5)的结构和化学性质。描述了短小芽孢杆菌AI-77。证实1的结构为6-[[1(S)-(3(S),4-二氢-8-羟基-1-氧代-1H-1H-2-苯并吡喃-3-基)-3-甲基丁基]。氨基] -4(小号),5(小号) -二羟基-6-氧代-3(小号)-aminohexanoic酸由X射线与化学研究和组合的结构2,3,4和5通过1的化学合成和光谱分析确定。
