Danshensu sodium salt

Danshensu (sodium salt) is odium salt of danshensu from the widely used Chinese herb Danshen. It can inhibited phenylephrine- and CaCl2-induced vasoconstriction in Ca2+-free medium. In vitro: Sodium danshensu showed a biphasic effects on vessel tension. While low dosage of sodium danshensu produced small contraction possibly through transient enhancement of Ca2+ influx, high dosage produced significant vasodilation mainly through promoting the opening of non-selective K+ channels and small-conductance calcium-sensitive K+ channels in the vascular smooth muscle cells.[1]In vivo: Danshensu did not change the expression of AGEs but partly blocked the increased expression of RAGE in the hippocampus of diabetic mice. Danshensu could ameliorate the cognitive decline in streptozotocin-induced diabetic mice by attenuating advanced glycation end product-mediated neuroinflammation.

How to use

In Vitro:

Sodium Danshensu is a mono sodium of danshensu which is a compound isolated from Salvia miltiorrhiza Bge. Danshensu is an efficient radical scavenger and antioxidant which exhibits higher scavenging activities against free hydroxyl radicals (HO()), superoxide anion radicals (O(2)(-)), 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) radicals and 2-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radicals than vitamin C. Sodium danshensu shows a biphasic effects on vessel tension. In phenylephrine-precontracted thoracic arteries with or without endothelium, low concentration (0.1-0.3 g/L) of sodium danshensu produces a weak contraction, while high concentrations (1-3 g/L) produces a pronounced vasodilator after a transient vasocontraction. Pre-incubation with sodium danshensu could inhibit vessel contraction induced by phenylephrine and potassium chloride in a concentration-dependent way. Sodium danshensu also inhibits phenylephrine- and CaCl2-induced vasoconstriction in Ca(2+)-free medium.
