Biological Activity

Description Doxofylline (Doxophylline) is a phosphodiesterase inhibitor and a xanthine derivative drug for asthma.
Targets
PDE [1]
In vitro
In vitro Doxofylline has PDE inhibitor activity and can increase the level of cAMP, which could, therefore, be used for the treatment of asthma and COPD. EC50 value of Doxofylline is 15 times higher than that of aminophylline in inhibiting the adenosine-induced relaxation of tracheal smooth muscle and 10 times higher in reducing the negative inotropic effect induced by adenosine on isolated guinea-pig atria. Doxofylline could effectively decrease the open probability of the calcium-activated potassium channels as a result of both the shortening of open period and the prolongation of close time. Doxofylline has greatly decreased affinity towards adenosine A1 and A2 receptors when compared with theophylline, which may contribute to the better safety profile. Moreover, unlike theophylline, Doxofylline does not interfere with calcium influx into cells nor antagonizes the action of calcium-channel blockers. [1]
In Vivo
In vivo Doxofylline has been shown to have better efficacy with fewer side effects than theophylline. 30 mg/kg Doxofylline increases heart rate of anaesthetized cat by 13 beats/min. The effective therapeutic dose of Doxofylline has less cardio-stimulant effects than Theophylline, such that Doxofylline does not out significantly increase the cardiac frequency nor does it have arrhythmogenic effects.

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.
