Xanthoxylin (Brevifolin), isolated from Zanthoxylum piperitum (Japanese pepper tree) and Sapium sebiferum (Chinese tallowtree), is a cytotoxic and fungicidal compound with the characteristics of a typical phytoalexin.
Xanthoxylin (RCX) exhibits potent cytotoxicity in a panel of different cancer cells. It presents IC50 values of 1.6 and 26.0?μM for the HCT116 and ACP-03 cancer cell lines, respectively. Xanthoxylin causes apoptosis in a time- and concentration-dependent manner and induces mitochondrial depolarization in HepG2 cells. It induces DNA intercalation, inhibited DNA synthesis and triggered the caspase-mediated apoptosis pathway in HepG2 cells, as observed by cell shrinkage, internucleosomal DNA fragmentation, externalization of phosphatidylserine, loss of mitochondrial transmembrane potential and activation of caspase-3, -8 and -9[1]. Xanthoxylin increases melanin production, number of dendrites, tyrosinase, and microphthalmia-associated transcription factor (MITF) expression in cultured B16F10 cells[2].
Xanthoxylin presents a potent in vivo antitumor effect in C.B-17 SCID mice engrafted with HepG2 cells[1].

Design, molecular Docking, synthesis and evaluation of Xanthoxylin hybrids as dual inhibitors of IL-6 and acetylcholinesterase for Alzheimer's disease
Bioorg Chem 2022 Apr;121:105670.PMID:35189442DOI:10.1016/j.bioorg.2022.105670.
Interleukin-6 (IL-6) and acetylcholinesterase (AChE) are two important targets implicated in progression of Alzheimer's Disease (AD). Simultaneous inhibition of both IL-6 and AChE by a molecule presents an effective strategy for the treatment of AD. In this study, the pharmacophores for inhibition of IL-6 and AChE are identified, and coupled to design novel molecules capable of acting as dual inhibitors of IL-6 and AChE. Literature review reveals that Xanthoxylin and a disubstituted or a carbamoyl amine are pharmacophore for IL-6 and AChE inhibition, respectively. Therefore, Xanthoxylin is coupled with various disubstituted amines or carbamoyl amines through alkyl linkers of different lengths (1-4 carbon atoms) to design two series of 80 compounds. All designed compounds are docked in AChE. Based on their docking score, 15 compounds are selected for synthesis and evaluation of AChE inhibitory activity. The compounds showing > 45% inhibition of EeAChE are selected for evaluation of IL-6 and butyrylcholinesterase (BuChE) inhibitory activities. Compound Y13g is found to be the most potent inhibitor of EeAChE, BuChE and IL-6. It is further evaluated in vivo using STZ-induced amnesia model in mice at three doses (0.2, 0.4 and 0.8 mg/kg), wherein it shows dose-dependent effects. At 0.8 mg/kg, it reverses the STZ-induced memory deficit, and shows histopathology similarly as in normal animals. The findings suggest that compounds derived from coupling of Xanthoxylin with piperazine through a 3-carbon chain provides a useful template for the development of new chemical entities effective against AD.
Metabolomic Profiling Identified Serum Metabolite Biomarkers and Related Metabolic Pathways of Colorectal Cancer
Dis Markers 2021 Dec 7;2021:6858809.PMID:34917201DOI:10.1155/2021/6858809.
Background: The screening and early detection of colorectal cancer (CRC) still remain a challenge due to the lack of reliable and effective serum biomarkers. Thus, this study is aimed at identifying serum biomarkers of CRC that could be used to distinguish CRC from healthy controls. Methods: A prospective 1 : 2 individual matching case-control study was performed which included 50 healthy control subjects and 98 CRC patients. Untargeted metabolomic profiling was conducted with liquid chromatography tandem mass spectrometry (LC-MS/MS) to identify CRC-related metabolites and metabolic pathways. Results: In total, 178 metabolites were detected, and an orthogonal partial least-squares-discriminant analysis (OPLS-DA) model was useful to distinguish CRC patients from healthy controls. Nine metabolites showed significantly differential serum levels in CRC patients under the conditions of variable importance in projection (VIP) > 1, p < 0.05 using Student's t-test, and fold change (FC) ≥ 1.2 or ≤0.5. The above nine metabolites were 3-hydroxybutyric acid, hexadecanedioic acid, succinic acid semialdehyde, 4-dodecylbenzenesulfonic acid, prostaglandin B2, 2-pyrocatechuic acid, Xanthoxylin, 12-hydroxydodecanoic acid, and formylanthranilic acid. Four potential biomarkers were identified to diagnose CRC through ROC curves: hexadecanedioic acid, 4-dodecylbenzenesulfonic acid, 2-pyrocatechuic acid, and formylanthranilic acid. All AUC values of these four serum biomarkers were above 0.70. In addition, the exploratory analysis of metabolic pathways revealed the activated states for the vitamin B metabolic pathway and the alanine, aspartate, and glutamate metabolic pathways associated with CRC. Conclusion: The 4 identified potential metabolic biomarkers could discriminate CRC patients from healthy controls, and the 2 metabolic pathways may be activated in the CRC tissues.
When a Tritrophic Interaction Goes Wrong to the Third Level: Xanthoxylin From Trees Causes the Honeybee Larval Mortality in Colonies Affected by the River Disease
J Chem Ecol 2021 Sep;47(8-9):777-787.PMID:34287796DOI:10.1007/s10886-021-01296-5.
The "River Disease" (RD), a disorder impacting honeybee colonies located close to waterways with abundant riparian vegetation (including Sebastiania schottiana, Euphorbiaceae), kills newly hatched larvae. Forager bees from RD-affected colonies collect honeydew excretions from Epormenis cestri (Hemiptera: Flatidae), a planthopper feeding on trees of S. schottiana. First-instar honeybee larvae fed with this honeydew died. Thus, we postulated that the nectars of RD-affected colonies had a natural toxin coming from either E. cestri or S. schottiana. An untargeted metabolomics characterization of fresh nectars extracts from colonies with and without RD allowed to pinpoint Xanthoxylin as one of the chemicals present in higher amounts in nectar from RD-affected colonies than in nectars from healthy colonies. Besides, Xanthoxylin was also found in the aerial parts of S. schottiana and the honeydew excreted by E. cestri feeding on this tree. A larva feeding assay where xanthoxylin-enriched diets were offered to 1st instar larvae showed that larvae died in the same proportion as larvae did when offered enriched diets with nectars from RD-colonies. These findings demonstrate that a xenobiotic can mimic the RD syndrome in honeybee larvae and provide evidence of an interspecific flow of Xanthoxylin among three trophic levels. Further, our results give information that can be considered when implementing measures to control this honeybee disease.
A novel ruthenium complex with Xanthoxylin induces S-phase arrest and causes ERK1/2-mediated apoptosis in HepG2 cells through a p53-independent pathway
Cell Death Dis 2018 Jan 23;9(2):79.PMID:29362398DOI:10.1038/s41419-017-0104-6.
Ruthenium-based compounds have gained great interest due to their potent cytotoxicity in cancer cells; however, much of their potential applications remain unexplored. In this paper, we report the synthesis of a novel ruthenium complex with Xanthoxylin (RCX) and the investigation of its cellular and molecular action in human hepatocellular carcinoma HepG2 cells. We found that RCX exhibited a potent cytotoxic effect in a panel of cancer cell lines in monolayer cultures and in a 3D model of multicellular cancer spheroids formed from HepG2 cells. This compound is detected at a high concentration in the cell nuclei, induces DNA intercalation and inhibits DNA synthesis, arresting the cell cycle in the S-phase, which is followed by the activation of the caspase-mediated apoptosis pathway in HepG2 cells. Gene expression analysis revealed changes in the expression of genes related to cell cycle control, apoptosis and the MAPK pathway. In addition, RCX induced the phosphorylation of ERK1/2, and pretreatment with U-0126, an MEK inhibitor known to inhibit the activation of ERK1/2, prevented RCX-induced apoptosis. In contrast, pretreatment with a p53 inhibitor (cyclic pifithrin-α) did not prevent RCX-induced apoptosis, indicating the activation of a p53-independent apoptosis pathway. RCX also presented a potent in vivo antitumor effect in C.B-17 SCID mice engrafted with HepG2 cells. Altogether, these results indicate that RCX is a novel anticancer drug candidate.
Neutrophil Immunomodulatory Activity of Farnesene, a Component of Artemisia dracunculus Essential Oils
Pharmaceuticals (Basel) 2022 May 23;15(5):642.PMID:35631467DOI:10.3390/ph15050642.
Despite their reported therapeutic properties, not much is known about the immunomodulatory activity of essential oils present in Artemisia species. We isolated essential oils from the flowers and leaves of five Artemisia species: A. tridentata, A. ludoviciana, A. dracunculus, A. frigida, and A. cana. The chemical composition of the Artemisia essential oil samples had similarities and differences as compared to those previously reported in the literature. The main components of essential oils obtained from A. tridentata, A. ludoviciana, A. frigida, and A. cana were camphor (23.0-51.3%), 1,8-cineole (5.7-30.0%), camphene (1.6-7.7%), borneol (2.3-14.6%), artemisiole (1.2-7.5%), terpinen-4-ol (2.0-6.9%), α-pinene (0.8-3.9%), and santolinatriene (0.7-3.5%). Essential oils from A. dracunculus were enriched in methyl chavicol (38.8-42.9%), methyl eugenol (26.1-26.4%), terpinolene (5.5-8.8%), (E/Z)-β-ocimene (7.3-16.0%), β-phellandrene (1.3-2.2%), p-cymen-8-ol (0.9-2.3%), and Xanthoxylin (1.2-2.2%). A comparison across species also demonstrated that some compounds were present in only one Artemisia species. Although Artemisia essential oils were weak activators of human neutrophils, they were relatively more potent in inhibiting subsequent neutrophil Ca2+ mobilization with N-formyl peptide receptor 1 (FPR1) agonist fMLF- and FPR2 agonist WKYMVM, with the most potent being essential oils from A. dracunculus. Further analysis of unique compounds found in A. dracunculus showed that farnesene, a compound with a similar hydrocarbon structure as lipoxin A4, inhibited Ca2+ influx induced in human neutrophils by fMLF (IC50 = 1.2 μM), WKYMVM (IC50 = 1.4 μM), or interleukin 8 (IC50 = 2.6 μM). Pretreatment with A. dracunculus essential oils and farnesene also inhibited human neutrophil chemotaxis induced by fMLF, suggesting these treatments down-regulated human neutrophil responses to inflammatory chemoattractants. Thus, our studies have identified farnesene as a potential anti-inflammatory modulator of human neutrophils.
