GREEN SYNTHESIS AND ANTIMICROBIAL EVALUATION OF SOME THIOSEMICARBAZONE AND SEMICARBAZONE DERIVATIVES.

The interaction of substituted pyridine carboxaldehyde with thiosemicarbazide and semicarbazide via a greener approach resulted in the synthesis of thiosemicarbazone and semicarbazone derivatives; respectively. The resultant compounds were synthesized in aqueous media and were characterized by FTIR and 1H-NMR spectral studies. The antimicrobial evaluation of the final compounds has proven that they are active against the strains (S. aureus, P. aeruginosa, A. niger, and C. glabrata) incorporating the microdilution method.
