Proxyphylline is a methylxanthine derivative clinical used as cardiac stimulant, vasodilator and bronchodilator.

Name	7-(β-Hydroxypropyl)theophylline
Synonyms	MFCD00022833 7-(2-hydroxypropyl)-1,3-dimethylpurine-2,6-dione (1,3-Dimethyl-7-[2-hydroxypropyl]-2,6-dioxopurine) EINECS 210-028-7 Proxyphylline 7-(2-Hydroxypropyl)theophylline

In Vitro	Proxyphylline has shown vasodilatory and cardiac stimulatory effects. Proxyphylline produces an increase in the coronary flow associated with a definite positive inotropic effect[1]. Proxyphylline inhibits tracheal PDE-activity and half-maximum relaxation of tracheal smooth muscle is obtained with 100 μg/mL proxyphylline[2]
In Vivo	In a double-blind cross-over study, proxyphylline exhibits bronchodilatory effect[3]. Proxyphylline inhibits cAMP and cGMP hydrolysis in human lung tissue. The apparent inhibition constant of proxyphylline is 0.06-0.7 mM at low cAMP concentrations and it is 1.0 mM at high cAMP concentrations[3].
