beta-HET (beta-Hydroxyethyltheophylline), the major metabolite of the antibronchospastic, antiasthmatic drug doxofylline was studied in several in vitro and in vivo trials to characterize its pharmaco-toxicological profile. When compared to the parent compound, beta-HET was found to be significantly less active.

Differentiation-based therapeutics are an underutilized but potentially a significant option for cancer treatment. The effect of methylxanthines on melanoma cell differentiation has been well documented. We report the in-vitro and in-vivo anticancer potential of a theophylline analogue, 7-(2-hydroxyethyl)theophylline (HET), on

Pharmacokinetics of a sustained release (SR) and conventional formulations of theophylline plus hydroxyethyltheophylline was compared with tablet aminophylline. Time concentration curve of serum theophylline with the three formulations after single and multiple dosage schedules revealed significantly retarded absorption with the
