海洋细菌弧菌 sp。 DS40M4 被发现可产生一种新的三儿茶酚酰胺铁载体 trivanchrobactin (1)、一种相关的新型双儿茶酚酰胺化合物 divanchrobactin (2),以及先前报道的铁载体 vanchrobactin (3) 和 anguibactin (4)。 Vanchrobactin 由 L-丝氨酸、d-精氨酸和 2,3-二羟基苯甲酸组成,而 trivanchrobactin 是由两个丝氨酸酯键连接的 vanchrobactin 线性三聚体。未检测到环状三万菌素产物。除了铁载体的产生外,弧菌提取物。对DS40M4进行生物活性分子筛选; anguibactin 被发现对 P388 小鼠白血病细胞系具有细胞毒性(IC50 < 15 μM)。
The marine bacterium Vibrio sp. DS40M4 has been found to produce a new triscatechol amide siderophore, trivanchrobactin (1), a related new biscatecholamide compound, divanchrobactin (2), as well as the previously reported siderophores, vanchrobactin (3) and anguibactin (4). Vanchrobactin is comprised of l-serine, d-arginine- and 2,3-dihydroxybenzoic acid, while trivanchrobactin is a linear trimer of vanchrobactin joined by two serine ester linkages. The cyclic trivanchrobactin product was not detected. In addition to siderophore production, extracts of Vibrio sp. DS40M4 were screened for biologically active molecules; anguibactin was found to be cytotoxic against the P388 murine leukemia cell line (IC50 < 15 μM).
