Synthesis and antimicrobial activity of some new substituted 9-[1H-pyrazolo[3,4-b] quinolin-1-YL] acridines

2-Chloro-6-methyl/methoxy-3-formylquinoline upon condensation with substituted 9- hydrazino-acridine afforded corresponding hydrazones which were cyclized under alkaline condition to give 9-[6-substituted-1H-pyrazolo[3,4-b]quinolin-1-yl] acridine analoges. All of the synthesized compounds were characterized by their elemental analysis, IR and NMR spectral studies. Biological screening of the prepared compounds have been screened on some strain of bacteria and fungus
