Menthol and Its Derivatives: Exploring the Medical Application Potential

ABSTRACT Menthol, a natural organic compound and the primary component of mint, exhibits diverse biological activities, including analgesic, anti‐inflammatory, antibacterial, neuroprotective, and anticancer effects. The chemical modification of menthol, through processes such as esterification and amination, further enhances these activities, expanding its potential applications in drug development, agriculture, and food preservation. This review explores the structure‐activity relationships (SAR) of menthol and its derivatives, emphasizing the significance of molecular modifications in enhancing their pharmacological effects. Research indicates that menthol and its derivatives can improve drug permeation, reduce inflammation, enhance memory, and even target cancer cells through various mechanisms. In addition, we examine the safety and pharmacokinetics of menthol and its derivatives to better understand their clinical potential. Although significant progress has been made in preclinical models, further research is necessary to fully elucidate their mechanisms of action and optimize their therapeutic efficacy in clinical settings. Continued innovation in drug delivery technologies and the development of novel menthol derivatives present promising prospects for future therapeutic applications.
