Methyl cinnamate (Methyl 3-phenylpropenoate), an active component of Zanthoxylum armatum, is a widely used natural flavor compound. Methyl cinnamate (Methyl 3-phenylpropenoate) possesses antimicrobial activity and is a tyrosinase inhibitor that can prevent food browning. Methyl cinnamate (Methyl 3-phenylpropenoate) has antiadipogenic activity through mechanisms mediated, in part, by the CaMKK2-AMPK signaling pathway^[1]. In Vitro: In 3T3-L1 cell model, Methyl cinnamate (Methyl 3-phenylpropenoate) inhibits adipocyte differentiation by attenuating expression of the adipogenic transcription factors SREBP-1, PPARγ, and C/EBPα and the transcriptional activity of PPARγ. In addition, Methyl cinnamate (Methyl 3-phenylpropenoate) activates the CaMKK2−AMPK signaling cascade involved in the regulation of adipogenesis^[1].
