PROXYPHYLLINE Usage And Synthesis

Chemical Properties

White Solid

Uses

A metabolite of Theophylline in human plasma.

Definition

ChEBI: Proxyphylline is an oxopurine.

Biological Activity

ki: 82 nm for bovine brain a1 adenosine receptorproxyphylline is an a1 adenosine receptor antagonist.the a1 adenosine receptor, the best characterized purinergic receptor family, can mediate responses via multiple pertussis toxin-sensitive gtp binding proteins to various different effectors.

in vitro

previous study showed that proxyphylline could selectively antagonize a1 adenosine receptors versus a2 adenosine receptors (ki = 850 μm for platelets) [1].

in vivo

in a previous study, rats that were allodynic following the vincristine injections were randomly allocated into four groups. theoesberiven f (a combination of proxyphylline and melilotus extract) was administered to rats. results showed that the decreased paw withdrawal threshold induced by vincristine injection was increased by theoesberiven f treatment and the increased withdrawal frequency to cold stimuli was also reduced by theoesberiven f treatment [2].

Purification Methods

Crystallise it from EtOH, aqueous MeOH or EtOAc. Roth Archiv Pharmazie 292 234 1959, Zelnik et al. Bull Soc Chim Fr 1733 1956, Beilstein 26 III/IV 2366.]
