In recent years, besides the main field of nonsteroidal anti-inflammatory agents, the interest towards pyrazolone derivatives has been renewed because of their wide biological and pharmacological applications [1]. Currently, particular attention is focused on such a class of compounds due to the affinity with sigma receptor and their relationship with cancer [2].To these purposes we planned to design, synthesize and evaluate the antiproliferative activity (MTS assays) of a new series of 3-methyl-2-(1-R-naphthalen-2-yl)-1,2-dihydropyrazol-3-one derivatives 1 against HeLa, MCF-7, LAN-5, Caco2 in order to explore their anticancer potential. Additionally, further elaboration of the amino derivative 1 led to the tetracycle 2, possessing a reactive tetrazinone core which conferred valuable antiproliferative activity as previously reported [3]. Synthesis and biological results will be presented. [1] G. Mariappan, B.P. Saha, L. Sutharson, Anki, S. Garg, L. Pandey, D. Kumar, J. Pharm. Res., 2010, 3(12), 2856. [2] E. Aydar, C.P. Palmer, M. B.
