Synthesis, Characterization and Biological Evaluation of Novel Triazolo- and Tetrazolopyrimidines

2-Hydrazinyl-4,6-diphenylpyrimidine was used as an excellent precursor for the synthesis of a new heterocyclic compounds such as 9, 11, 13, 15, 20, 22 and 23. The compounds were characterized on the basis of IR, 1H-NMR, mass spectral data and elemental analysis. The newly synthesized compounds were screened for their anticancer activity against MCF-7 cell line (breast carcinoma). Some of these compounds revealed that they possess highly significant activity. Also, the synthesized compounds have been evaluated for their in vitro antibacterial and antifungal activities. Keywords - Triazolopyrimidine, Pyrazinopyrimidine, Pyrimidotriazoloindole, Pyrimidotetrazine, Tetrazolopyrimidine and Breast Carcinoma
