Biological Activity

Salvianolic acid A is a natural water-soluble polyphenolic antioxidant that inhibits protein-protein interactions mediated by the Src homology 2 (SH2) domains of Src-family tyrosine kinases, including Src and Lck. By blocking SH2 domain binding, it disrupts downstream kinase signaling pathways and scavenges free radicals, thereby reducing oxidative stress and inhibiting platelet activation and cellular injury.

Solubility

Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 99 mg/mL (200.22 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
Ethanol 99 mg/mL
Water 33 mg/mL
FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
