Abstract

The article is aimed to synthesize, characterize and screening the biological activity of novel a series of 6-(Benzo Thiophen-3-Yl)-3-Para-Substituted-[1,2,4] Triazolo[3,4-a] Phthalazine Derivatives (8 a-j)with good yields. The newly synthesized compounds were characterized by IR, 1H-NMR, 13C NMR and Mass spectral data. The anti-microbial activity of the novel compounds were screened by disc diffusion method. Compounds 8h, 8g, and 8f demonstrated good antimicrobial activity against all the tested microbial strains. Fused Phialazine 1, 2,4 Triazole linked thiophene with 2,5 di fluoro nucleus has shown good antibacterial and antifungal activities.
