生物活性

Vescalagin is a hexahydroxyphenol. Vescalagin is isolable from Camu-camu (Myrciaria dubia) and immature wax apple fruits. Vescalagin exhibits inhibitory activity against a variety of enzymes, with a Ki value of 5.87 nM against AChE, 3.89 nM against BChE, 11.75 nM against hCA I, 16.23 nM against hCA II, and 16.08 nM against α-glucosidase. Vescalagin inhibits hCA I, hCA II and α-glucosidase in a non-competitive manner. Vescalagin downregulates JNK/p38 MAPK to protect pancreatic β-cells and improve insulin secretion in methylglyoxal-treated rats. Vescalagin reduces hyperglycemia and hypertriglyceridemia in rats fed a high-fructose diet. Vescalagin possesses anti-inflammatory and antioxidant properties[1].

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.
