Description

In Vitro

Cinnamtannin A2 (0.125-2.0 μg/mL) inhibits LDL oxidation induced by copper ions or MeO-AMVN^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Cinnamtannin A2 (10 mg/kg; i.p. for 30 days) ameliorates the level of KIM1 and NAGL in 5/6 nephractomized rats by regulating Nrf2- Keap1 pathway^[2].
Cinnamtannin A2 (10 μg/kg; p.o.) increases the secretion of insulin and glucagon-like peptide-1 (GLP-1) in plasma of mice^[1].
Cinnamtannin A2 (10 μg/kg; p.o.) significantly promotes phosphorylation of both IRB and IRS-1 in mice^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Male Sprague-Dawley rats (250-300 g) were induced chronic renal failure (CRF) by removing the kidneys^[2]
Dosage:	10 mg/kg
Administration:	I.p. for 30 days
Result:	Ameliorated the altered level of creatinine, blood urea nitrogen, Neutrophil gelatinase-associated lipocalin, Kidney Injury Molecule-1 and cytokines in the serum and microalbuminurea. Reduced the oxidative stress level. Attenuated the altered expression of proteins involved in Nrf2-Keap1 pathway in the kidney tissue. Reduced the tubular injury score in the kidney tissue.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
