Received: 8 April 2011; in revised form: 9 May 2011 / Accepted: 11 May 2011 / Published: 24 May 2011 Abstract: A series of new N 1-(coumarin-7-yl)amidrazones incorporating N-piperazines and related congeners were synthesized by reacting the hydrazonoyl chloride derived from 7-amino-4-methylcoumarin with the appropriate piperazines. The chemical structures of the newly prepared compounds were supported by elemental analyses, 1H-NMR, 13C-NMR, and ESI-HRMS spectral data. The antitumor activity of the newly synthesized compounds was evaluated. Among all the compounds tested, 7-{2-[1-(4-(1-benzyl-2-ethyl- 4-nitro-1H-imidazol-5-yl)piperazin-1-yl)-2-oxopropylidene
