Cas No.: 330808-88-3
Sample solution is provided at 25 µL, 10mM.
Vardenafil is a potent and selective inhibitor of phosphodiesterase type5 (PDE5) with the IC50 value of 0.7 nM in enzymatic assay in vitro [1]. Vardenafil HCl Trihydrate is a salt form of vardenafil. [1]
Vardenafil has shown a greater selective inhibition towards PDE5 than PDEs from bovine, with the IC50 values of 180nM,>10000nM, 2500nM, 4000nM and 11nM for PDE1, PDE2, PDE3, PDE4 and PDE6, respectively. Besides, Vardenafil has been reported to significantly enhance the SNP-induced, ACh-induced and transmural electrical stimulation-induced relaxation of human trabecular smooth muscle. Vardenafil has been revealed to increase the amount of cGMP in human corpus cavernosum. Apart from these, Vardenafil has also enhanced the length of penile in the conscious rabbit [1].

| Kinase experiment [1]: | |
|
Enzyme inhibition assays |
PDE5 and 3H-cGMP were added in DMSO (final concentration of DMSO 0.1%). Incubation period was 15 min at 30 ℃. All tests were done in duplicate and were repeated at least three times. The IC50 value for the PDE5 inhibition were determined from sigmoidal curves, fitted to plots of enzyme activity vs log compound concentration using a GraphPad curve fitting program. |
| Cell experiment [1]: | |

Cell lines |
Human trabecular smooth muscle cells |
|
Preparation method |
This compound is soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 °C for several months. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
