ionization‐tandemmassspectrometry (UHPLC‐ESI‐MS/MS) and ion mobility spectrometry (IMS)–high‐resolution massspectrometry (HRMS) to fully characterize the GP derivatization products. Analytes were studied in positive ionization mode, and MS/MS was performed using nonresonance and resonance excitation collision‐induced dissociation.ResultsWe observed the successful GP derivatization of spironolactone
基本原理螺内酯是一种用于治疗多种疾病的类固醇药物,给药后会迅速广泛代谢。由于源内碎片和电喷雾电离相对较差的电离,使用质谱 (MS) 测量螺内酯及其代谢物仍然具有挑战性。因此,需要改进测量方法,特别是在样品量较小的情况下。方法采用螺内酯的吉拉德试剂 P (GP) 衍生化来提高响应,并为螺内酯及其代谢物的测量提供基于 MS 的解决方案。我们进行了超高效液相色谱-电喷雾电离-串联质谱(UHPLC-ESI-MS/MS)和离子迁移谱(IMS)-高分辨率质谱(HRMS)来全面表征GP衍生化产物。在正电离模式下研究分析物,并使用非共振和共振激发碰撞诱导解离进行 MS/MS。结果我们使用真实的化学标准品观察到螺内酯及其代谢物成功的 GP 衍生化。 GP 衍生化的螺内酯及其代谢物观察到信号增强了 1-2 个数量级。此外,GP 衍生化消除了源内碎片。最后,我们对螺内酯治疗组和对照动物的小体积小鼠血清(20 μL)进行了

Spironolactone is a renal competitive aldosterone antagonist. One of its most important metabolite is the 7 alpha-methylthio spironolactone: thus it is very important to have an efficient and safe access to this compound, for pharmacokinetic studies. In this context, we synthesized this metabolite by thioalkylation of 7 alpha-thio spironolactone using Hunig's base with a very good yield. We also used our procedure to prepare, with an easy work-up and high yields, 7 alpha-thioether and thioester derivatives of spironolactone, that could be useful for further Structure-Activity Relationships studies.
