Methyl cinnamate

Methyl cinnamate (CAS No.: 103-26-4) is a plant derived phenylpropanoid ester commonly identified as a bioactive constituent of Zanthoxylum armatum and related botanical sources, and it is broadly categorized in life sciences research as a natural product tool compound for studying antimicrobial responses, melanogenesis associated enzymology, inflammatory signaling, vascular biology, and adipogenesis related metabolism in preclinical systems. Current evidence supports its functional role as a tyrosinase inhibitory molecule and as a modulator of adipocyte differentiation linked to CaMKK2 AMPK pathway activation in 3T3 L1 preadipocyte models, with additional reports describing effects consistent with regulation of inflammatory and vasorelaxant processes, although these latter mechanisms are generally treated as pathway level observations requiring context specific validation. Across in vitro assay platforms, activity is commonly described at micromolar scale exposures, often spanning low to moderate micromolar ranges depending on endpoint selection, organism or cell type, and assay conditions, while antimicrobial performance is typically assessed using strain dependent susceptibility formats in which inhibitory levels can vary across a broad micromolar to higher concentration interval. In biomedical discovery workflows, this molecule is therefore used primarily as a reference or exploratory pharmacology probe in cell based phenotypic screening, enzyme focused assays, and mechanism oriented studies, and it may also be included in animal experiment designs that investigate metabolic or inflammatory biology under controlled laboratory conditions, where the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
