Abstract : 2-Hydroxy-5-nitro benzoic acid 1 has been synthesized from acetyl salicylic acid known as aspirin. The synthesized compound has been characterized using proton, carbon-13 Nuclear Magnetic Resonance data. The evaluation of its in vivo antipyretic activities above the Wistars rats shows that the derivative 1 is most active than its analogue aspirin. The derivative 1 shows an average temperature decrease of 1,4°C at the minimal concentration of 0,125 mol/l against Plasmodium bergei inoculated to the Wistars rats, whereas aspirin doesn’t show any activity under the same conditions. The higher antipyretic activity of the derivative 1 is explained by the pharmacophore character of the phenolic group reinforced with intramolecular H-bonds and the aromatic electron-withdrawing effect of substituents
Keywords : Aspirin derivative, higher in vivo antipyretic activity, phenolic group, electron-withdrawing substituents, pharmacophores for antipyretic activity.
