nigripes (called Wuling Shen in Chinese)¸ was found to be a selectiveinhibitor against monoamine oxidase A (MAO-A) and might play an important role in the clinical usage of this edible fungus as an anti-depressive traditional Chinese medicine (TCM). Based on the discovery and hypothesis, a variety of (R)-5-MM analogs were synthesized and evaluated in vitro against two monoamine oxidase isoforms (MAO-A
The syntheses of racemic and optically active pseudodeflectusin and ustusorane C are described. The 1H- and 13C-NMR data for our synthetic pseudodeflectusin and ustusorane C were identical to those of the corresponding natural products. We also synthesized the proposed structure of aspergione A and B whose 1H- and 13C-NMR data were identical to those of ustusorane C and pseudodeflectusin. The 1H- and 13C-NMR spectra of our synthetic aspergione A and B were different from those of the natural compounds. Our results confirm that aspergione A and B are in fact ustusorane C and pseudodeflectusin, respectively.
我们描述了外消旋和光活性假偏转素及乌斯托索烯 C 的合成。我们合成的假偏转素和乌斯托索烯 C 的 1H-和 13C-NMR 数据与相应的天然产物完全一致。我们还合成了拟议的天青素 A 和 B 的结构,其 1H-和 13C-NMR 数据与乌斯托索烯 C 和假偏转素一致。我们合成的天青素 A 和 B 的 1H-和 13C-NMR 光谱与天然化合物不同。我们的结果确认天青素 A 和 B 实际上分别是乌斯托索烯 C 和假偏转素。
