Alizarin

Catalog No.S2526 Synonyms: Anthraquinonic

For research use only.

Alizarin (Anthraquinonic) strongly inhibits P450 isoform CYP1A1, CYP1A2 and CYP1B1 with IC50 of 6.2 μM, 10.0 μM and 2.7 μM, respectively; weakly inhibits CYP2A6 and CYP2E1, and does not inhibit CYP2C19, CYP3A4 and CYP3A5.

Biological Activity

Description Alizarin (Anthraquinonic) strongly inhibits P450 isoform CYP1A1, CYP1A2 and CYP1B1 with IC50 of 6.2 μM, 10.0 μM and 2.7 μM, respectively; weakly inhibits CYP2A6 and CYP2E1, and does not inhibit CYP2C19, CYP3A4 and CYP3A5.

CYP1B1 [1] CYP1A1 [1] CYP1A2 [1]
2.7 μM 6.2 μM 10.0 μM
In vitro

Alizarin weakly inhibits CYP2A6 and CYP2E1. Alizarin shows competitive inhibition against CYP1B1 with Ki of 0.5 μM. Alizarin reduces the mutagenicity of MeIQx, which induced by each CYP1A2 or CYP1B1, while does not effectively reduce the mutation induced by B[a]P. [1] Alizarin exhibits antioxidants against iodophenol-derived phenoxyl radicals, superoxide anion radicals and lipid peroxidation in rat liver microsomes. [2]

In vivo Alizarin also reduces the hepatic content of thiobarbituric acid-reactive substances and the serum level of alanine aminotransferase in poisoned animals. [2]

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.
