Bioactivity | Levocetirizine-d4 ((R)-Cetirizine-d4) is the deuterium-labeled Levocetirizine (HY-B0814)[1]. Levocetirizine ((R)-Cetirizine) is a third-generation peripheral H1-receptor antagonist. Levocetirizine is an antihistaminic agent which is the R-enantiomer of Cetirizine. Levocetirizine has a higher affinity for the histamine H1-receptor than (S)-Cetirizine and can effectively treat allergic rhinitis and chronic idiopathic urticaria[2]. |
Invitro | 氢、碳和其他元素的稳定重同位素已被纳入药物分子中,主要作为药物开发过程中定量的示踪剂。氘化引起了人们的关注,因为它可能影响药物的药代动力学和代谢谱[1]。 |
