As the global population grows and ages, cancer has become a leading cause of death, partly due to significant reductions in mortality rates from stroke and coronary heart disease in many countries. Despite significant advances in cancer therapy, there is a substantial interest in developing new anticancer agents with different mechanisms of action, as cancer cells have developed resistance to current treatments. Noteworthy anticancer agents in this category include doxorubicin, 5-fluorouracil, and methotrexate among others. There has been a concerted effort to develop rapid, sensitive, and non-destructive methods for detecting the effects and mechanisms of anticancer drugs both in vitro and in vivo. Currently, methods such as mass spectrometry-based liquid chromatography (LC-MS), capillary electrophoresis (CE), and mass spectrometry-based gas chromatography (GC-MS) are still widely used to study anticancer drugs. However, electroanalytical techniques have recently gained popularity due to their higher sensitivity, greater selectivity, eco-friendliness, shorter analysis time, and lower cost. These techniques are now frequently used to detect anticancer drugs. Identifying anticancer drugs at low concentrations and with high sensitivity is crucial for tracking these medications.

Consequently, global F-NPS use poses a critical challenge, as metabolic data from F-NPS have often proven insufficient to support law enforcement agencies in combating emerging analogs. In this study, an <em>in vitro</em> human liver microsome model was used to incubate nine alicyclic F-NPS derivatives and the metabolites was analyzed by using liquid chromatography-ion trap tandem time-of-flight mass spectrometry. We systematically characterized the metabolic profiles of the alicyclic F-NPS and elucidated the structural determinants that influence metabolism. Our findings revealed that <em>sp</em><sup>3</sup>-carbon monohydroxylation occurring at the alicyclic ring, a distinctive metabolic pathway in this subclass, is governed by the C–H Laplacian bond order, intermediate radical stability, alicyclic ring rigidity, and steric hindrance, while also competing with analogous metabolic pathways at other sites. Notably, alicyclic dehydrogenation, a previously unreported metabolic pathway, correlated with the stability of alicyclic alkenes and conjugative stabilization through adjacent carbonyl groups. <em>N</em>-oxidation metabolism was significantly modulated by <em>N</em>-dealkylation metabolism at adjacent positions and substituents on the phenyl group of the core. Furthermore, >N–CH₂–CH₂– serves as the primary metabolic hotspot within the F-NPS skeleton structure, with the total relative contents of corresponding metabolites accounting for > 80 % (and up to 98 %). The monohydroxylation of the phenyl group adhered to an electrophilic substitution mechanism governed by the electron density and both the theoretical calculation results and mass spectrometric data consistently indicated that <em>sp</em><sup>2</sup>-carbon monohydroxylation occurred exclusively at the phenethyl group in the tail.

To address these challenges, this study developed an integrated strategy to identify and isolate acetylcholinesterase inhibitors (AChEIs) from Gardenia jasminoides Ellis (<em>GJE</em>)—a plant with both medicinal and edible value—while evaluating their potential against Alzheimer’s disease (AD). First, affinity ultrafiltration-liquid chromatography-mass spectrometry (AUF-LC-MS) (a technique that uses AChE as a target to specifically capture binding compounds from complex extracts) was employed to screen candidate AChEIs from <em>GJE</em>. To verify the anti-dementia potential of these candidates and analyze their binding stability with AChE, we used molecular docking integrated with molecular dynamics simulation (a type of kinetic simulation approach that predicts static binding affinity and dynamic complex stability, respectively). Next, based on activity screening results, offline two-dimensional countercurrent chromatography (Offline 2D-CCC) (a separation technique that first groups compounds with similar polarity via 1st-dimensional separation and then purifies each group with optimized solvent systems via 2nd-dimensional separation) was used to isolate the active components. To clarify the inhibitory mechanism of the isolated compounds on AChE, we performed targeted enzymatic kinetics analysis (including determining inhibition type, calculating the half-inhibitory concentration IC₅₀, and measuring the inhibition constant K<em>ᵢ</em>—parameters that characterize how compounds block AChE activity). To systematically confirm the anti-AD mechanism of <em>GJE</em> components and assess potential toxic effects, we applied network pharmacology—a method that constructs “compound-target-disease” interaction networks to reveal multi-component, multi-target, and multi-pathway relationships (instead of focusing on single targets). This approach helped identify cross-talk between <em>GJE</em>’s therapeutic effects and potential toxicity. Nine potential AChEIs were finally screened from <em>GJE</em>: Geniposidic acid, Genipin-1-<em>O</em>-gentiobioside, Gardenoside, Croceic acid, Rutin, Crocin I, Crocin II, Quercetin, and Nevadensin. Their binding energies with AChE (a key parameter for evaluating binding strength) were −8.8, −8.9, −8.2, −8.7, −9.3, −10.4, −10.6, −10.2, and −10.3 kcal/mol, respectively.
