| Cell experiment [1]: | |
|
Cell lines |
human hepatocytes |
|
Preparation method |
The solubility of this compound in DMSO is >16.6mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
1 μM |
|
Applications |
Tadalafil (1 μM) increased CYP3A protein expression in human hepatocytes. |
| Animal experiment [2,3]: | |
|
Animal models |
Rat model with bilateral cavernous neurotomy (BCN)-induced penile damage and hypo-oxygenation, Mice with cavernous nerve resection |
|
Dosage form |
2 mg/kg, daily for 3 months |
|
Application |
Tadalafil (2 mg/kg) almost completely restored penile oxygenation and abolished neurotomy induced increase and substantially rescued muscle/fiber ratio in penile sectionsin sham-operated rats. Tadalafil decreased the number of apoptotic cells and increased the phosphorylation of the 2 survival associated kinases Akt and extracellular signal-regulated kinase 1/2 in mice. |
|
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. |

Tadalafil, also known as IC351 or Cialis, is a potent, reversible and competitive small-molecule inhibitor of phosphodiesterase 5 (PDE5), a predomiant PDE in the pulmonary vasculature that hydrolyzes cyclic guanosine monophosphate (cGMP) and is involved in the pathobiology of pulmonary arterial hypertension (PAH). The inhibitory effect of tadalafil is PDE5 specific with the selectivity of 10000 times greater than that of PDE1, PDE4, PDE7, PDE8, PDE9 and PDE10 and of 780 times greater than that of PDE6. Although it is used for the treatment of erectile dysfunction through oral administration, tadalafil also improves the vasoconstrictive-predominate condition of PAH through elevating cGMP levels in pulmonary vessels resulted from PDE5 inhibition.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
