O-Methylasparvenone (1) and asparvenone (2) were isolated from an Aspergillus parvulus Smith broth in a microbial screening for 5-HT2C ligands and found to be 5-HT2C antagonists. They represent the first nitrogen-free serotonin ligands. The absolute configuration of 1 was determined to be S by X-ray analysis of the corresponding Mosher-ester. A short and efficient synthesis of rac-1 was developed. This protocol was applied to the synthesis of derivatives of 1 and a structure-affinity relationship was established.
在针对5-HT2C配体的微生物筛选中,从小球曲霉史密斯肉汤中分离出了O-甲基天冬酰胺(1)和天冬酰胺(2),发现它们是5-HT2C拮抗剂。它们是首批无氮血清素配体。通过对相应莫舍尔酯的X射线分析确定1的绝对构型为S。开发了一种简短而有效的外消旋-1合成方法。该方法应用于1的衍生物合成,并建立了结构-亲和力关系。
