Biological Activity

Mirodenafil (SK3530) is a potent and selective inhibitor of phosphodiesterase type 5 (PDE5). By blocking PDE5-mediated hydrolysis of cyclic guanosine monophosphate (cGMP), it prevents cGMP degradation, leading to elevated intracellular cGMP levels. This accumulation downstream activates protein kinase G (PKG) and promotes smooth muscle relaxation in vascular tissues, thereby enhancing erectile responses in preclinical 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).
