Nordoxepin-D3 hydrochloride是Nordoxepin的氘标记类似物，是三环类抗抑郁药多塞平的主要活性代谢物。Nordoxepin-D3 hydrochloride在生物等效性研究、临床毒理学和法医尿液药物检测的LC-MS/MS和GC/MS应用中用作内标，以量化代谢物水平。

Dabigatran acyl-β-D-glucuronide is a major active metabolite of the thrombin inhibitor dabigatran . The prodrug of dabigatran, dabigatran etexilate , is hydrolyzed by plasma esterases to form dabigatran, which is metabolized primarily by the UDP-glucuronosyltransferase (UGT) isoform UGT2B15 to form dabigatran acyl-β-D-glucuronide. Dabigatran acyl-β-D-glucuronide increases activated partial thromboplastin time (aPTT) in isolated human platelet-poor plasma equipotently to dabigatran.
