(1R)-(-)-Menthyl acetate

(1R)-(-)-Menthyl acetate (CAS No.: 2623-23-6) is a naturally occurring monoterpene ester and a menthol derived small molecule commonly cataloged in natural products and chemical biology collections for microbiology, barrier biology, and transdermal absorption research, where it is used as a functional probe to study membrane related effects rather than as a selective receptor ligand; available evidence indicates broad antimicrobial and antifungal activity in vitro with inhibitory potency reported in low volume per volume to single digit volume per volume ranges in standard susceptibility assays and with measurable suppression of fungal biofilm development, while mechanistic interpretation generally centers on physicochemical perturbation of microbial membranes, altered membrane permeability, and downstream disruption of biofilm associated stress adaptation pathways, and in skin permeation studies it is widely characterized as an enhancer of 5 aminolevulinic acid transport across the stratum corneum, supporting its use in experimental models of cutaneous delivery, diffusion kinetics, and formulation screening; because validated single protein targets and pathway specific binding constants are limited for this compound, it is most appropriately classified as a multiparametric bioactive modulator in phenotypic workflows, including cell based antimicrobial profiling, ex vivo skin penetration platforms, and exploratory in vivo pharmacology models, with concentrations or doses selected according to assay format, tissue matrix, formulation composition, and specific research objectives in early stage drug discovery and translational preclinical investigation.
