title: Synthesis, spectral analysis, antibacterial and antifungal activities of some 4,6-diaryl-4,5-dihydro-3-hydroxy-2[H]-indazole-a novel fused indazole derivative.
abstract: A novel class of 4,6-diaryl-4,5-dihydro-3-hydroxy-2[H]-indazoles 25-32 were synthesized and evaluated for their in vitro antibacterial and antifungal activities. Four Compounds, which all possessed electron withdrawing functional groups (-Cl, -NO(2), -Br) 27, 28, 30 and 32 were more potent against the tested bacterial/fungal strains than the standard bacterial and fungal drugs ciprofloxacin and fluconazole respectively.
