ENPROFYLLINE Usage And Synthesis

Description

3-Propylxanthine is a xanthine derivative that antagonizes adenosine receptors (Kis = 44, 32, and 6.3 μM for A1, A2A, and A2B, respectively) and cAMP phosphodiesterase (Ki = 42 μM). Through these actions, 3-propylxanthine induces smooth muscle relaxation, blocks smooth muscle contraction and VEGF secretion driven by adenosine receptor agonists, and reduces bronchial hyperresponsiveness.

Uses

Bronchodilator.

Uses

Enprofylline is a xanthine lacking adenosine receptor antagonism.

Definition

ChEBI: Xanthine bearing a propyl substituent at position 3. A bronchodilator, it is used for the symptomatic treatment of asthma and chronic obstructive pulmonary disease, and in the management of cerebrovascular insufficiency, sickle cell disease, and diabetic n uropathy.

in vivo

Enprofylline increases heart rate (HR). Injection of Enprofylline (7.5 and 30 mg/kg) increases HR in male WT mouse from 529±23 to 590±20 and 562±20 after the low and high dose, respectively[3].
A high dose of Enprofylline (30 mg/kg) also decreases temperature compared with saline injection in female (but not in males) WT mice, but a low dose (7.5 mg/kg) has little effect on mouse temperature[3].

Animal Model:A1RKO mice (were cross-bred to C57BL/6 mice for six generations) and A2ARKO mice (were backcrossed to C57BL/6 mice for more than 10 generations)[3]
Dosage:30 mg/kg
Administration:Intraperitoneally injected (bolus) at 2-h intervals
Result:Increased HR in male WT mouse from 529±23 to 590±20 and 562±20 after the low (7.5 mg/kg) and high dose (30 mg/kg), respectively.

IC 50

A2B receptor: 7 μM (Ki)
