Two anabaenopeptin-type peptides, lyngbyaureidamides A and B, together with two previously reported peptides lyngbyazothrins C and D, were isolated from the cultured freshwater cyanobacterium Lyngbya sp. (SAG 36.91). Their structures were determined by spectroscopic and chemical methods. Lyngbyazothrins C and D were also able to inhibit the 20S proteasome with IC(50) values of 7.1 μM and 19.2 μM, respectively
从培养的淡水蓝藻 Lyngbya sp. 中分离出两种鱼腥藻肽类肽,lyngbyaureidamides A 和 B,以及两个先前报道的肽 lyngbyazothrins C 和 D。(SAG 36.91)。它们的结构是通过光谱和化学方法确定的。Lyngbyazothrins C 和 D 也能够抑制 20S 蛋白酶体,IC(50) 值分别为 7.1 μM 和 19.2 μM,而 lyngbyaureidamides A 和 B 在 50 μM 时没有活性。
