the signal transduction of steroid hormone receptors. Single nucleotide polymorphisms in the gene encoding FKBP51 have been associated with a variety of psychiatric disorders. Rapamycin and FK506 are two macrocyclic natural products, which tightly bind to most FKBP family members, including FKBP51 and FKBP52. A bioisosteric replacement of the α-ketoamide moiety of rapamycin and FK506 with a sulfonamide
FK506结合蛋白(FKBP)51和52是可调节类
固醇激素受体
信号转导的伴侣蛋白。编码FKBP51的
基因中的单核苷酸多态性已与多种精神疾病有关。
雷帕霉素和FK506是两个大环
天然产物,它们与大多数FKBP家族成员紧密结合,包括FKBP51和FKBP52。考虑到保留保守的氢键,用磺酰胺对
雷帕霉素和FK506的α-酮酰胺部分进行
生物等位取代。重点研究了基于固体支持物的合成方案,该方案导致对FKBP51和FKBP52具有亚微摩尔亲和力的
配体。一种磺酰胺类似物的分子结合模式通过X射线晶体学证实。
