产品描述

Hydroxyzine-d8 is intended for use as an internal standard for the quantification of hydroxyzine by GC- or LC-MS. Hydroxyzine is a histamine H1 receptor antagonist (Ki = 1.9 nM).1 It binds competitively with the H1 receptor inverse agonist mepyramine with an IC50 value of 80 µM in polymorphonuclear leukocytes.2 In vivo, it is metabolized to the H1 receptor antagonist cetirizine .3 In situ, hydroxyzine (10 µM) prevents recruitment of rolling leukocytes induced by histamine in rat mesentery post-capillary venules.4 Hydroxyzine also decreases anxiety-like behavior in mice, increasing the time spent in the open arms of the elevated plus maze and in the light side of the light-dark exploration test.5 Formulations containing hydroxyzine have been used in the treatment of anxiety and as antihistamines in the treatment of allergic rhinitis.

Efficient synthesis of deuterium labeled hydroxyzine and aripiprazole

J Labelled Comp Radiopharm 2015 Jun 15;58(7):304-7.PMID:26011470DOI:10.1002/jlcr.3298

Hydroxyzine and aripiprazole are active pharmaceutical ingredients that have been largely acknowledged for their antipsychotic properties. Deuterium labeled isotopes of hydroxyzine and aripiprazole are internal standards that can aid in the further research of non-isotopic forms via quantification analysis using HPLC-MS/MS. The synthesis of Hydroxyzine-d8 was accomplished by coupling piperazine-d8 with 4-chlorobenzhydryl chloride followed by the reaction of the first intermediate with 2-(2-chloroethoxy) ethanol to afford 11.7% of Hydroxyzine-d8 with 99.5% purity. The synthesis of aripiprazole-d8 was also achieved in two steps. 1,4-Dibromobutane-d8 reacted with 7-hydroxy-3,4-dihydro-2(1H)-quinolinone. The first intermediate was then coupled with 1-(2, 3-dichlorophenyl)piperazine hydrochloride to produce 33.4% of aripiprazole-d8 with 99.93% purity.
