产品描述 | Ebastine-d5is intended for use as an internal standard for the quantification of ebastine by GC- or LC-MS. Ebastine is a potent second generation histamine H1receptor antagonist (IC50= 45 nM) that does not cross the blood brain barrier.1It undergoes extensive first-pass metabolism by hepatic cytochrome P450 3A4 into its active carboxylic acid metabolite, carebastine , which exerts most of the pharmacological effects.2At 10 μM, ebastine has been shown to inhibit T cell proliferation and the production of Th2-type pro-inflammatory cytokines by macrophages.3 1.Abou-Gharbia, M., Moyer, J.A., Nielsen, S.T., et al.New antihistamines: Substituted piperazine and piperidine derivatives as novel H1-antagonistsJ.
