A series of 3,6-disubstituted 1,2,4–triazolo[3,4-b]-1,3,4-thiadiazoles and 7H-[1,2,4] triazolo[3,4-b][1,3,4]thiadiazine were synthesized from methyl {3-[(6-chloropyridin-3- yl)methyl]-4-oxo-3,4-dihydrophthalazin-1-yl}acetate in multiple steps. Most of the newly synthesized compounds were screened for their antimicrobial activity against variety of human pathogenic bacteria’s. Many of the compounds were found to be potent as antimicrobials
