Synthesis and antimicrobial activities of a new series of 4- S-[4 1-amino-5 1-oxo-6 1-substituted benzyl-4 1,5 1-dihydro-1 1,2 1,4 1-triazin-3-yl]mercaptoacetyl-3-arylsydnones

The synthesis of some 4- S-(4 1-amino-5 1-oxo-6 1-substituted benzyl-4 1,5 1-dihydro-1 1,2 1,4 1-triazin-3-yl)mercaptoacetyl-3-arylsydnones by the reaction of 3-aryl-4-bromoacetylsydnones with 6-substituted-4-amino-3-mercapto-1,2,4-triazin-5-ones is described. The IR, 1H NMR, mass spectra and elemental analysis characterized the newly synthesized compounds. The synthesized compounds were screened for their antimicrobial activity. All the compounds showed higher activity than that of standard drug during antimicrobial studies and the activity was comparable with the standard drug for antifungal activity. [Display omitted]
