Cinnamyl acetate

Cinnamyl acetate (CAS No.: 103-54-8) is a naturally occurring phenylpropanoid ester and fragrance related small molecule, commonly identified in plant derived volatile fractions and historically used in flavor and aroma contexts, that is currently positioned in life sciences research as a bioactive natural product scaffold for chemical biology, microbiology, and early stage anti infective discovery workflows; based on available literature level evidence and class informed inference, it is primarily categorized as a membrane active and stress modulating antimicrobial lead like compound rather than a selective, single protein inhibitor, with reported broad spectrum antibacterial effects that are generally interpreted to involve perturbation of microbial membrane integrity, modulation of redox homeostasis, and downstream disruption of energy metabolism and macromolecular biosynthesis, while definitive high confidence target deconvolution and pathway assignment remain incomplete and should be experimentally validated in each platform using orthogonal assays such as membrane permeability profiling, transcriptomic response mapping, and phenotypic rescue designs; in vitro activity is typically described at micromolar to low millimolar exposure windows with organism and assay dependent variability, and may be benchmarked in microbiological panels through growth inhibition and viability readouts rather than fixed universal potency constants, whereas mammalian cell based studies commonly apply concentration ranges selected to separate mechanistic bioactivity from nonspecific cytotoxicity; in translationally oriented preclinical research settings, this molecule is used as a reference or exploratory component in combination testing, structure activity relationship expansion of aromatic ester analogs, and phenotypic screening cascades that evaluate microbial burden, biofilm related behavior, and host cell compatibility in vitro and in exploratory animal models, and the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
