5-Amino-1-phenyl-1H-pyrazole-4-carbohydraizde(1) was used as a key to synthesize new imidazopyrazol-5(1H)-one 5, pyrazolopyrimidines 7 and 9. Furthermore, imidazopyrazoles 13, 15, pyrazolopyridine 16 and pyrazolopyrazolopyridopyrimidine 17 were prepared from pyrazoles 10 and 11. The structure of the new compounds was confirmed by spectral data as well as elemental analysis. Some compounds were selected by the national cancer institute NCI (USA) for anticancer activity against different human cancer cell lines. The results indicated that compound 12 exhibited strong anticancer activity toward Renal Cancer UO-31(GI, 42.81%), while compound 3 was strong active against Breast Cancer MCF7 (GI, 49.88%) and moderate against T-47D (GI, 38.15%) cell lines. However, compound 17 showed strong activity against Leukemia CCRF-CEM (GI, 41.37%) and SR (GI, 44.95%), whereas, compound 9 showed weak activity toward all tested cancer cell lines.
