Some quinolone antibiotics cause increases in levels of theophylline in plasma that lead to serious adverse effects. We investigated the mechanism of this interaction by developing an in vitro system of human liver microsomes. Theophylline (1,3-dimethylxanthine) was incubated with human

In a continuing effort to explore structural and functional dynamics in RNA catalysis, we have created a series of allosteric hammerhead ribozymes that are activated by theophylline. Representative ribozymes exhibit greater than 3000-fold activation upon effector-binding and cleave with maximum

Pharmacokinetics of theophylline was investigated in Cyp1(+/+) wild-type mice, Cyp1a1(-/-) and Cyp1a2(-/-) knockout mice, and humanized hCYP1A1_1A2 mice lacking either the mouse Cyp1a1 or Cyp1a2 gene. Animals received a single dose of theophylline (8 mg/kg i.p.), either alone or pretreated

RNAs often exhibit a high degree of conformational dynamics and heterogeneity, leading to a rugged energy landscape. However, the roles of conformational heterogeneity and rapid dynamics in molecular recognition or RNA function have not been extensively elucidated. Ultrafast time-resolved fluorescence

HPLC Analysis of Xanthines on Purospher® STAR RP-18 endcapped

Xanthine is a purine base found in most human body tissues and fluids as well as in other organisms. Methylated xanthines (methylxanthines), which include caffeine, paraxanthine, theobromine, and theophylline, commonly used for their effects as mild stiµlants and as bronchodilators, notably in the treatment of asthma symptoms. This application shows the efficient separation of several common xanthines and may be applied their analysis in any number of desired matrices.
