Biological Activity

Description Acarbose(BAY g 5421) is an inhibitor of intestinal alpha-glucosidase, used to treat type 2 diabetes mellitus.
alpha-glucosidase [1]
In vitro

Acarbose reversibly inhibits intestinal alpha-glucosidases, enzymes responsible for the metabolism of complex carbohydrates into absorbable monosaccharide units.[1]

In vivo Acarbose reduces the absorption of monosaccharides derived from dietary carbohydrates, which play an important role in the metabolism and toxicity of some chemical compounds. Acarbose alone potentiates carbon tetrachloride (CCl4) andacetaminophen (AP) hepatotoxicity, as evidenced by significantly increased levels of both alanine transaminase (ALT) and aspartate transaminase (AST) in the plasma of rats pretreated with acarbose. [2] Acarbose treatment suppresses weight gain and the development of hepatic steatosis in sqstm1 gene knockout mice. Acarbose treatment up-regulates hepatic expression of the pparalpha, ucp-2, and abca1 genes, as well as srebp1c, pparalpha, and ppargamma in adipose tissue. [3] Acarbose-treated rats have lower body weights at 3 months of age with unaltered food consumption, and a similar effect is seen with a high-fructose diet in the JCR:LA-corpulent rat. [4] Acarbose markedly improves postprandial hyperglycemia, postprandial insulin level, total cholesterol, triglyceride, and free fatty acid level in Goto-Kakizaki (GK) rats. Acarbose efficiently reduces the number of monocytes adherent to aortic endothelial layer, improves acetylcholine-dependent vasodilatation, and reduces intimal thickening of the aorta in GK rats.

Calculation results:

Working concentration: mg/ml;

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.
