RESUMEN
Ten ester derivatives from caffeic acid were synthesized, and their antinociceptive properties are evaluated in mice. The most active compound, dodecyl ester derivative, exhibited potent and dose-related activity against the writhing test, with a calculated ID(50) value of 15.1 (11.9-19.1)micromol/kg and MI of 78.8% being several times more active than reference drugs. It was also effective in other experimental models, such as formalin, capsaicin and glutamate-induced pain tests, but was inactive in the hot-plate test. Although the mechanism of action has still not been elucidated, these results appear to support its therapeutic potential against painful diseases.
