Biological Activity

Sasapyrine (Salsalate) is a nonsteroidal anti-inflammatory agent that acts as a prodrug of salicylate and functions as an activator of AMP-activated protein kinase (AMPK) and an inhibitor of the NF-kB signaling pathway. By activating AMPK, Sasapyrine stimulates fatty acid oxidation and suppresses lipid synthesis in metabolic tissues. Additionally, its inhibition of NF-kB signaling attenuates inflammatory responses and reduces the expression of pro-inflammatory cytokines. [1]

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).
