Design, synthesis, characterization and in vitro antimicrobial evaluation of 4,6-diaryl-4,5-dihydro-2-phenyl-2H-indazol-3-ols.
New 4,6-diaryl-4,5-dihydro-2-phenyl-2H-indazol-3-ols 25-32 were designed, synthesized and in vitro microbially evaluated using clinically isolated bacterial strains viz Staphylococcus aureus, beta-Heamolytic streptococcus, Vibreo cholerae, Salmonella typhii, Shigella felxneri and fungal strains viz Aspergillus flavus, Mucor, Rhizopus and Microsporum gypsuem. Results of this study showed that the nature of the substituents on the phenyl rings viz., methyl, methoxy, chloro, nitro as well as the bromo functions at the meta and para positions of the aryl moieties determined the nature and extent of the activity of the fused indazolonol compounds 25-32.
