healthy volunteers following oral administration were analyzed to identify circulating and excreted metabolites of the parent drug. One major circulating metabolite (1) was found in pooled human plasma samples, accounting for approximately half of the observed drug-related material. Isolation of metabolite 1 from urine samples followed by MS and NMR studies led to a putative structural assignment of 1
GSK2798745 是一种瞬时受体电位香草酸 4 (TRPV4) 离子通道的拮抗剂,最近在用于治疗心脏和呼吸系统疾病的临床试验中进行了研究。对口服给药后从健康志愿者收集的人血浆和尿液样本进行分析,以确定母体药物的循环和排泄代谢物。在合并的人血浆样本中发现了一种主要的循环代谢物 ( 1 ),约占观察到的药物相关物质的一半。从尿样中分离代谢物1 ,然后进行 MS 和 NMR 研究,推定结构分配为1其中 GSK2798745 的羟基化发生在中心环上,产生含有三个立体中心的五取代环己烷结构。开发了所提出结构的两种独特的化学合成方法,以确认代谢物1的身份,并为生物表征提供克数。
