hybrid metabolites, were discovered from the endophytic fungus Periconia sp. F-31. Their structures and absolute configurations were elucidated by extensive spectroscopic data and electronic circular dichroism analyses. Preliminary biological evaluation revealed that pericoannosins C–D exhibited anti-HIV activities with IC50 values of 15.5 and 13.5 μM. Furthermore, the bioinspired syntheses of pericoannosins
在我们的生物合成假说的指导下,从内生真菌Periconia sp。中发现了皮环红素C–F,四种新的PKS–NRPS杂合代谢物。F-31。通过广泛的光谱数据和电子圆二色性分析,阐明了它们的结构和绝对构型。初步生物学评估表明,二十碳五环素C–D具有抗HIV活性,IC 50值为15.5和13.5μM 。此外,还成功完成了生物启发的pericoannosins C–E的合成。
