New Heterocyclo-Substituted Pyrazolo[3,4-b]pyridine Derivatives.

Research Abstract
In this investigation and in continuance with our previous work in the synthesis of some heterocyclic compounds fused with pyridine moiety, we used 3-amino-4,6-diphenyl-1H-pyrazolo[3,4-b]pyridine (II) as starting material to synthesize many heterocyclic compounds containing pyrazolopyridine moiety.

Synthesis of Some NewHeterocyclic Compounds Based on Thiopyrane-2-thione as Antimicrobial Agents

Research Abstract
Some new derivatives containing both thiopyrane-2-thione (I) and β-lactams, thiazolidinones, triazoles, sulfonamides and tricyclic compound have been previously prepared. Here we attempted to use the compound I, for synthesis of new heterocycles
