A sensitive and specific method for the estimation of theophylline-7-acetic acid in plasma by high performance liquid chromatography is described. Acidified plasma is extracted with chloroform-n-butanol (85: 15), back extracted with phosphate buffer (0.5 mmol-1, pH 6.5), and finally the

Theophylline-polyrotaxane conjugates were synthesized by coupling theophylline with alpha-cyclodextrins (alpha-CDs) in the polyrotaxane. The polyrotaxane is a molecular assembly in which many alpha-CDs are threaded onto a poly(ethylene glycol) (PEG) chain capped with L-phenylalanine (L-Phe). Theophylline-7-acetic acid was activated by

Some esters of 7-theophyllinylacetic acid were synthetized, characterized physicochemically and tested for their anti-inflammatory properties. As compared to indomethacin, reference anti-inflammatory drug, all synthetized compounds were less toxic. The anti-inflammatory properties are influenced by the nature of the ester group
