Application

Aminophylline has been used:
  • as a positive control in the selective inhibitor of nuclear export, KPT-350 zebrafish dosing experiments
  • as a positive control for the determination of the spasmolytic activity of C. aeruginosa extracts
  • as a phosphodiesterase (PDE) inhibitor in inhibitor studies to quantify its potency to inhibit PDE4A1A and PDE3A enzyme in an assay

Biochem/physiol Actions

Aminophylline is a methylxanthine compound containing theophylline andethylenediamine in a ratio of 2:1. It acts as a bronchodilator and is used to treat chronic lung diseases like asthma, bronchitis, or emphysema.

There is a need to prognosticate the severity of cystic fibrosis (CF) detected by newborn screening (NBS) by early assessment of CF transmembrane conductance regulator (CFTR) protein function. We introduce novel instrumentation and protocol for evaluating CFTR activity as reflected

Screening of AMP- and GMP-producing enzymes such as phosphodiesterases (PDEs), ligases, and synthetases would be simplified by the ability to directly detect unmodified nucleoside monophosphates. To address this need, we developed polyclonal and monoclonal antibodies that recognize AMP and GMP

Adenosine cardiovascular magnetic resonance (CMR) can accurately quantify myocardial perfusion reserve. While regadenoson is increasingly employed due to ease of use, imaging protocols have not been standardized. We sought to determine the optimal regadenoson CMR protocol for quantifying myocardial perfusion

The functional roles of the capsaicin receptor, TRPV1, outside of sensory nerves are unclear. We mapped TRPV1 in the mouse circulation, revealing extensive expression in the smooth muscle of resistance arterioles supplying skeletal muscle, heart and adipose tissue.  Activation of
