β-Caryophyllene

β-Caryophyllene (CAS No.: 87-44-5) is a naturally occurring bicyclic sesquiterpene widely distributed in plant essential oils and is primarily classified in research catalogs as a natural product bioactive and pharmacological tool compound for inflammation, immunology, and neurobiology related discovery workflows; mechanistically, it is recognized as a selective cannabinoid receptor type 2 agonist and is commonly used to interrogate CB2 associated signaling networks, including Gi or o coupled modulation of cyclic AMP, regulation of MAPK and NF kappa B linked inflammatory transcriptional programs, and broader effects on cytokine associated cellular responses in stimulated immune and tissue relevant systems. In vitro studies reported across the literature generally describe measurable activity at CB2 in the nanomolar to micromolar range depending on assay platform, receptor expression context, and pathway readout, while off target effects and polypharmacology profiles may vary with concentration, matrix composition, and exposure duration, supporting its use as a context dependent probe rather than a single pathway definitive modulator. In biomedical research settings, β-Caryophyllene is frequently applied in cell based inflammation or oxidative stress paradigms, receptor deconvolution experiments, transcriptomic or proteomic pathway mapping, and in vivo mechanistic studies in preclinical animal models designed to examine immune signaling and tissue response biology under controlled laboratory conditions; the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives, and study interpretation generally benefits from orthogonal target validation, appropriate vehicle and antagonist controls, and assay specific benchmarking against reference agonists.
