A new indole diterpene, 26-dihydroxyaflavininyl acetate (1), along with five known analogs (2–6) were isolated from the liquid fermentation of Aspergillus flavus GZWMJZ-288, an endophyte from Garcinia multiflora. The structures of these compounds were identified through NMR, MS, chemical reaction, and X-ray diffraction experiments. Enzyme inhibition activity screening found that compounds 1, 4, and
从黄曲霉 GZWMJZ-288(一种来自藤黄果的内生菌)的液体发酵中分离出一种新的吲哚二萜,26-二羟基黄素乙酸酯 (1) 以及五种已知的类似物 (2-6)。通过NMR、MS、化学反应和X射线衍射实验鉴定了这些化合物的结构。酶抑制活性筛选发现,化合物1、4、6与NPC1L1具有良好的结合亲和力,其中化合物6在10μM浓度下表现出比依折麦布更强的结合能力。此外,化合物5对α-葡萄糖苷酶具有抑制活性,IC50值为29.22±0.83μM,比阿卡波糖强13倍。结果表明,这些黄素类似物可以作为开发针对 NPC1L1 和 α-葡萄糖苷酶的药物的先导化合物。生物活性化合物与 NPC1L1 和 α-葡萄糖苷酶的结合模式也通过计算机对接研究进行。
