Abstract:
The present invention relates to a novel α,β-unsaturated amide compound expressed by following Chemical Formula 1, a method for preparing a composition for preventing or treating obesity; and a composition for preventing or treating obesity including the α,β-unsaturated amide compound, the method being characterized by comprising: screening a compound exhibiting the effect of treating or preventing obesity from a compound library including one or more of α,β-unsatruated amide compound(s); and preparing a composition for treating or preventing obesity containing the selected compound. [Chemical Formula 1]. Since the α,β-unsatruated amide compound of the present invention is a compound having a scaffold which mimics a natural substance, piper amide, showing various activity, the α,β-unsatruated amide compound would exhibit various pharmacological activities. Also, as an intermediate, soluble by-products are produced by using β-phosphono-N-hydroxysuccinimidyl ester, and thus a pure compound is obtainable without a need for performing the typically used purification process through column chromatography. Furthermore, pharmacological activity is tested from a chemical library thus synthesized to screen a compound which serves as an agonist against BRS-3a and thus this compound can be useful as a composition for treating or preventing obesity.
