General description

3-hydroxy Desloratadine is a major metabolite of desloratadine and loratadine, which are non-sedating tricyclic antagonists of the histamine H1 receptor and antihistamine drugs used to manage allergic rhinitis and chronic idiopathic urticaria.

Application

3-Hydroxy Desloratadine finds application in metabolomics and drug discovery research

Biochem/physiol Actions

3-hydroxydesloratadine formation involves the oxidation of desloratadine by cytochrome P450 (CYP2C8) and subsequent glucuronidation by UDP-glucuronosyltransferase UGT2B10 in cryopreserved human hepatocytes. This pathway leads to the production of 3-hydroxydesloratadine, a major active human metabolite.

Features and Benefits

  • High quality compound suitable for multiple research applications
  • Compatible with a wide variety of chromatographic and spectrometry techniques
