Ordering Information

Biological Activity

SB-3CT is a potent, mechanism-based gelatinase inhibitor that selectively targets matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9). Inhibition of these gelatinases disrupts extracellular matrix degradation and blocks downstream proteolysis of essential structural proteins. Consequently, SB-3CT attenuates toxic signaling pathways, prevents pericellular laminin degradation, and suppresses neuronal apoptosis and neurovascular damage in preclinical cerebral ischemia models.

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).
