Biological Activity
Vardenafil is an orally active and selective inhibitor of phosphodiesterase-5 (PDE5) (IC50 =. By competitively blocking PDE5-mediated hydrolysis of cyclic guanosine monophosphate (cGMP), it increases intracellular cGMP levels and promotes downstream NO/cGMP signaling pathway activation. This accumulation of cGMP leads to vascular smooth muscle relaxation and enhanced vasodilation, supporting its investigation in cardiovascular and metabolic disease models. [1]

| Solvent | Solubility & Note |
|---|---|
| DMSO |
98 mg/mL
(200.57 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.) |
| Water | 98 mg/mL |
| Ethanol | 16 mg/mL |
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).
