Pyrazole and Nicotinonitrile Derivatives Synthesized from Sulfa Drugs, and Their Antibacterial Activity

Utility of sulfadiazine and sulfaguanidine in synthesis of new series of pyrazoles and 2-pyridones is described. Diazotization of sulfadiazine that results in formation of diazonium salt 2 followed by coupling of the latter with active methylene compounds

Synthesis of some potential antibacterial pyrazoles and pyrazolones

1-Guanyl-3-methyl-4-[4'-(substituted)sulphonamoyl]hydrazono-2-pyrazolin- 5-one nitrate and 1-guanyl-3,5-diphenyl-4-[4'- (substituted)sulphonamoyl]azopyrazole nitrate have been synthesised and characterised by spectral techniques.

Synthesis of some New Pyrazolin-5-ones

Synthesis of some sufonamoylhydrazonopyrazolin-5-ones have been reported.
