Abstract
4-Amino-3-(4-chlorophenyl)-1H-pyrazol-5-yl-(3,5-dimethyl-1H-pyrazol-1-yl)-methanone and 6-amino-3-(4-chlorophenyl)-5-methyl-1,6-dihydro-7H-pyrazolo[4,3-d]-pyrimidin-7-one derivatives have been synthesized. Most of the newly synthesized compounds have good to excellent antimicrobial activity. Compounds 7a,b and 15 exhibited higher anticancer activity than the doxorubicin as reference drug.

A series of [4-amino-3-(4-chlorophenyl)-1H-pyrazol-5-yl](3,5-dimethyl-1H-pyrazol-1-yl)-methanone and 6-amino-3-(4-chlorophenyl)-5-methyl-1,6-dihydro-7H-pyrazolo[4,3-d]-pyrimidin-7-one have been synthesized from ethyl 4-amino-3-(4-chlorophenyl)-pyrazol-5-carboxylate. The newly synthesized compounds were characterized by IR, 1H NMR, 13CNMR, Mass spectra and Elemental analysis. The compounds were evaluated for their in vitro antimicrobial and anticancer activity. Among the synthesized compounds, compounds 7a,b and 15 exhibited higher anticancer activity than the doxorubicin as reference drug. Most of the newly synthesized compounds have good to excellent antimicrobial activity.
