(+)- and (-)-Lesinurad were isolated as atropisomers from racemic lesinurad for the first time. No interconversion was observed between the two atropisomers under various conditions tested. The two atropisomers showed significant differences in hURAT1 highly expressed HEK293 cell-based inhibition assays, monkey pharmacokinetic studies, and human recombinant CYP2C9 stability studies. It was speculated that (+)-lesinurad might offer a better hyperuricemia/gout therapy than (-)-lesinurad or the racemate.
首次从外消旋雷西纳德中分离出(+)-和(-)-雷西纳德作为阻转异构体。在各种测试条件下,未观察到两种阻转异构体之间的相互转化。在基于高表达hURAT1的HEK293细胞的抑制试验、猴子药代动力学研究和人重组CYP2C9稳定性研究中,这两种阻转异构体表现出显著差异。据推测,(+)-雷西纳德可能比(-)-雷西纳德或外消旋体提供更好的高尿酸血症/痛风治疗效果。
