Ordering Information

Biological Activity

Loureirin B is a natural flavonoid extracted from Dracaena cochinchinensis that acts as an inhibitor of plasminogen activator inhibitor-1 (PAI-1). It downregulates p-ERK and p-JNK signaling in TGF-β1-stimulated fibroblasts to attenuate fibrotic phenotypes. In addition, Loureirin B promotes insulin secretion by upregulating Pdx-1 and MafA expression, increasing intracellular ATP, inhibiting KATP channels, and stimulating intracellular Ca2+ influx.

Solubility

Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 100 mg/mL (316.1 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
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).
