Abstract

This research project is based on the biological results obtained under financial support from FAPESP, project-number: 2001/03756-1 e 2004/11351-0, exhibited by polifunctional phenols and its derivatives. The compound, sodium 4-[5-(4-hydroxy-3-methoxyphenyl)-3-oxo-penta-1,4-dienyl]-2-methoxy-phenolate, DM1 exhibited marked action as a potent antitumor agent against melanoma and breast cancer. Also, this compound exhibited an excellent activity as powerful adjuvant agent for a higher antitumor activity of conventional chemotherapeutic drugs, as a potent antimethastatic and antimutagenic, protecting and stimulating bone marrow. For this reason, we planned with DM1: a) In vivo analgesic assay in rats. We planned the synthesis of new substituted acetophenone and derivatives starting from 2-hydroxy-5-(2-methylbut-2-enyl)acetophenone used as stardard antitumor reference. Therefore we planned the synthesis of 1,4-pentadien-3-ones, starting from iodated polifunctional phenols and aromatic 1-alkyne or with alkyl acrylate, respectivelly, in the presence of different Pd-catalysts. All the compounds will be purified and their structures shall be characterized by spectroscopic methods and organic elemental quantitative analysis.Finally, antitumor, antioxidant, analgesic and anti-inflammatory properties will be determined and the impact of the in vitro treatment with synthesized componds, on epigenetic regulation of immune system cells, besides looking for markers of differential metilation on DNA, after the employment of these compounds.
