Technical Data

Formula

C22H19N3O4
Molecular Weight 389.4 CAS No. 171596-29-5
Solubility (25°C)* In vitro DMSO 88 mg/mL (225.98 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.9mg/ml Taking the 1 mL working solution as an example, add 50 μL of clarified DMSO stock solution of 78 mg/ml to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Tadalafil is a PDE-5 inhibitor with IC50 of 1.8 nM in a cell-free assay. Tadalafil is at least 9000 times more selective for PDE5 than most of the other families of PDEs, with the exception of PDE11. It can partial inhibits PDE11
Targets
PDE5 [1]
(Cell-free assay)
1.8 nM
In vitro Tadalafil binds to PDE5 with KD of 2.4 nM. cGMP stimulates the binding of [3H]Tadalafil. [1] Tadalafil (1 mM) results increased CYP3A protein expression in human hepatocytes. [2]
In vivo Tadalafil (2 mg/kg) almost completely restores penile oxygenation and abolishes neurotomy induced increase and substantially rescues muscle/fiber ratio in penile sectionsin sham-operated rats. [3] Tadalafil (2 mg/kg or 10 mg/kg) significantly improves neurological functional recovery and increases cerebral vascular density and the percentage of BrdU-positive endothelial cells around the ischemic boundary. Tadalafil selectively increases cGMP but not cAMP in brain of rats. [4] Tadalafil decreases the number of apoptotic cells and increases the phosphorylation of the 2 survival associated kinases Akt and extracellular signal-regulated kinase 1/2 in mice. [5]
Features Much more potent to PDE-5 than PDE-1 or PDE-6.
