Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	Histamine H1 receptor ^[1]
In vitro	Meclizine is a histamine H1 receptor antagonist used to treat nausea and motion sickness, possesses anticholinergic, central nervous system depressant, and local anesthetic effects. ^[1] Meclizine is an agonist ligand for mouse CAR (constitutive androstane receptor), and an inverse agonist for human CAR. Meclizine increases mCAR transactivation in a dose-dependent manner, stimulates binding of steroid receptor coactivator 1 to the murine receptor in vitro. In contrast, meclizine suppresses hCAR transactivation and inhibits the phenobarbital-induced expression of the CAR target genes, cytochrome p450 monooxygenase (CYP)2B10, CYP3A11, and CYP1A2, in primary hepatocytes derived from mice expressing hCAR, but not mCAR. ^[2]
In vivo	Meclizine administration to mice increases expression of CAR target genes in a CAR-dependent manner. ^[2] Meclizine silence oxidative metabolism, suppresses apoptotic cell death in a murine cellular model of polyglutamine (polyQ) toxicity. ^[3]
