Synthesis of Some Biologically Active Pyrazolylphthalazine Derivatives and Acyclo-C-nucleosides of 6-(2,4,6-trimethylphenyl)-1,2,4-triazolo[3,4-a]phthalazine
1-Chloro-4-(2,4,6-trimethylphenyl) phthalazine (2) was used as a precursor for preparation of some novel pyrazolylphthalazine derivatives 6-13 and 15-19. Moreover, the acyclonucleosides 20-23 a-e were prepared by the reaction of hydrazinophthalazine derivative 3 with different aldoses. All new phthalazine derivatives were characterized using H-1 NMR, C-13 NMR, FTIR, mass spectrum and elemental analysis. The newly synthesized compounds showed highly activity against different species of bacteria and fungi, in addition to an excellent antiinflammatory property.
