| description | Aspirin is an analgesic and a derivative of salicylic acid. The synthesis of
methyl acetylsalicylate and methyl benzoylsalicylate as aspirin analog has been
carried out by esterification. Methyl acetylsalicylate and methyl benzoylsalicylate
were synthesized by reacting methyl salicylate from wintergreen oil with acetyl
chloride and benzoyl chloride in pyridine (modified Schotten-Baumann method).
The analgesic activity of the synthesized compound was evaluated by acetic acid
induction method (writhing test) in male mice strain swiss. The orally doses methyl
acetylsalicylate and methyl benzoylsalicylate are 50, 100 and 200 mg/kgBW.
Acetylsalicylic acid at dose of 100 mg/kgBB as a positive control and
carboxylmethylcellulose 0.5% as a negative control.
The synthetic products is methyl acetylsalicylate (mp. 51 °C) with yielded of
59.07% and methyl benzoylsalicylate (mp. 87 °C) with yielded of 48.44%. Both
products had a white solid and odour like aspirin. Structure elucidation those
synthetic products by infrared spectrofotometer (FTIR), 1H-NMR and mass
spectrofotometer showed the structure of methyl acetylsalicylate and methyl
benzoylsalicylate. Respectively, the analgesic percent protection of methyl
acetylsalicylicate was 20.92%, 47.70% and 63.39%. Respectively, the analgesic
percent protection of methyl benzoilsalicylate was 34.31%, 69.04% and 83.47%.
Methyl acetylsalicylate and methyl benzoylsalicylate had a stronger analgesic
activity than aspirin (32.01%) at the same dose (100 mg/kgBW). It can be concluded
that methyl acetylsalicylate and methyl benzoylsalicylate have an analgesics activity. |
