SYNTHESIS OF SOME NUCLEOSIDES WITH EXPECTED BIOLOGICAL ACTIVITY

Aiming to increase the biological activity of some interesting nucleosides, the presented study is directed to prepare some cytidine and inosine nucleosides concerning modification in their structures. 2`,3`-O-Isopropylidene cytidine was used as a suitablFurthermore, 5-bromocytidine was reacted with maleic anhydride and cytidine was allowed to react with furfural and with 2-carboxylic thiophene. On the other side, the synthesis of some other desired compounds can also be achieved by introducing some modif
