Theophylline and silymarin are potent inhibitors of IL-4 secretion from activated human basophils

American Journal of Experimental and Clinical Research, 2018
Basophils are the most important cells in allergic reactions and secret interleukin 4 (IL-4) and tumor necrosis factor α (TNFα) mediators. Theophylline as a phosphodiesterase 4 inhibitor and silymarin with its anti-inflammatory effects seem to be useful ...

In Vitro and In Vivo Evaluation of pH-Sensitive Hydrogels of Carboxymethyl Chitosan for Intestinal Delivery of Theophylline

ISRN Pharmaceutics, 2012
Chitosan is a natural polymer which has limited solubility. Chitosan gets solubilized at acidic pH but is insoluble at basic pH. In the present study, carboxymethyl chitosan (CMC) was prepared which shows high swelling in basic pH and thus can delay the ...

An RNA aptamer-based electrochemical biosensor for detection of theophylline in serum.

Journal of the American Chemical Society, 2008
An electrochemical RNA aptamer-based biosensor for rapid and label-free detection of the bronchodilator theophylline was developed. The 5'-disulfide-functionalized end of the RNA aptamer sequence was immobilized on a gold electrode, and the 3'-amino ...
