Synthesis and Biological Evaluation of Theophylline Methyl 1,3,4-Oxadiazole as Anticancer Agents

Abstract: A series of theophylline methyl 1,3,4-oxadiazole small molecules were obtained via cyclization of theophylline-7-acetohydrazide with different benzoic acids. The compounds (IVa–j) were synthesized and characterized by using conventional methods. The new compounds obtained were evaluated for their cytotoxic effect in three different cancer lines, the activity obtained varies depending upon the structure of a molecule. The compound (IVb) and (IVf) showed promising effect than other compounds of the series. Thus, these two derivatives have the potential for developing as anticancer agents.

Nucleoside derivative for preventing and treating inflammatory reaction as well as application thereof

The invention provides a nucleoside derivative for preventing and treating inflammatory reaction as well as application of the derivative to preparation of medicines for preventing and treating inflammatory diseases. The nucleoside derivative for preventing and treating inflammatory reaction, which is provided by the invention, can obviously improve the disease conditions of pancreatitis, hepatitis, arthritis and the like, can improve the damaged and inflammatory indexes of organs and has the effect better than that of a positive control medicine indometacin. Compared with the traditional anti-inflammatory medicines aspirin, ibuprofen, indometacin, butazodine, diclofenac, piroxicam and glucocorticoid, the nucleoside derivative for preventing and treating inflammatory reaction, which is provided by the invention, has the advantage that the side effect is obviously smaller.
