(-)-Guaiol is a sesquiterpene alcohol that has been found in several traditional Chinese medicinal plants and has antiproliferative, pro-autophagic, insect repellent, and insecticidal biological activities. It selectively inhibits proliferation of A549 and H1299 non-small cell lung carcinoma (NSCLC) cells over BEAS-2B normal lung cells (IC50s = 121.7, 211.5, and 297.1 μM, respectively). It also dose-dependently induces formation of DNA double-strand breaks (DSBs) and autophagy in A549 and H1299 cells and increases levels of microtubule-associated protein 1 light chain 3 isoform II (LC3-II). (-)-Guaiol (8 mg/kg three times per week) inhibits tumor growth in an NSCLC mouse xenograft model. It deters A. aegypti and A. quadrimaculatus mosquitoes from feeding on a synthetic blood substitute with a biting-deterrent index (BDI) of 0.82 when used at a concentration of 25 nmol per cm2. (-)-Guaiol is also lethal to fourth instar M. separata and third instar P. xylostella larvae (LD50s = 0.07 and 8.9 mg/larva, respectively).

(-)-Guaiol triggers immunogenic cell death and inhibits tumor growth in non-small cell lung cancer
Mol Cell Biochem 2022 Nov 28.PMID:36441354DOI:10.1007/s11010-022-04613-y.
(-)-Guaiol is a sesquiterpenoid found in many traditional Chinese medicines with potent antitumor activity. However, its therapeutic effect and mechanism in non-small cell lung cancer (NSCLC) have not been fully elucidated. In this study, (-)-Guaiol was found to induce immunogenic cell death (ICD) in NSCLC in vitro. Using (-)-Guaiol in vivo, we found that (-)-Guaiol could suppress tumor growth, increase dendritic cell activation, and enhance T-cell infiltration. Vaccination experiments suggest that cellular immunoprophylaxis after (-)-Guaiol intervention can suppress tumor growth. Previous studies have found that (-)-Guaiol induces apoptosis and autophagy in NSCLC. Apoptosis and autophagy are closely related to ICD. To explore whether autophagy and apoptosis are involved in (-)-Guaiol-induced ICD, we used inhibitors of apoptosis and autophagy. The results showed that the release of damage-associated molecular patterns (DAMPs) was partly reversed after inhibition of apoptosis and autophagy. In conclusion, these results suggested that the (-)-Guaiol triggers immunogenic cell death and inhibits tumor growth in NSCLC.
(-)-Guaiol regulates autophagic cell death depending on mTOR signaling in NSCLC
Cancer Biol Ther 2018 Aug 3;19(8):706-714.PMID:29611762DOI:10.1080/15384047.2018.1451277.
(-)-Guaiol, a sesquiterpene alcohol with the guaiane skeleton, has been found in many Chinese medicinal plants and been reported to comprise various guaiane natural products that are well known for their antibacterial activities. Previously, we have shown its antitumor activity by inducing autophagy in NSCLC cells. However, its potential mechanism in inducing autophagy is still under our investigation. Here, data from our western blotting assays showed that, in NSCLC cells, (-)-Guaiol significantly blocked the mTORC2-AKT signaling by suppressing mTOR phosphorylation at serine 2481 (S2481) to induce autophagy, illustrated by the increasing ratio of LC3II/I. Besides, it impaired the mTORC1 signaling by inhibiting the activity of its downstream factors, such as 4E-BP1 and p70 S6K, all of which could obviously rescued by the mTOR activator MHY1485. Afterwards, results from biofunctional assays, including cell survival analysis, colony formation assays and flow cytometry assays, suggested that (-)-Guaiol triggered autophagic cell death by targeting both mTORC1 and mTORC2 signaling pathways. In summary, our studies showed that (-)-Guaiol inhibited the proliferation of NSCLC cells by specifically targeting mTOR signaling pathways, including both mTORC1 and mTORC2 signaling, providing a better therapeutic option for substituting rapamycin in treating NSCLC patients.
(-)-Guaiol regulates RAD51 stability via autophagy to induce cell apoptosis in non-small cell lung cancer
Oncotarget 2016 Sep 20;7(38):62585-62597.PMID:27566579DOI:10.18632/oncotarget.11540.
(-)-Guaiol, generally known as an antibacterial compound, has been found in many medicinal plants. Its roles in tumor suppression are still under investigation. In the study, we mainly focused on exploring its applications in dealing with non-small cell lung cancer (NSCLC) and the underlying mechanisms. Here, we show that (-)-Guaiol significantly inhibits cell growth of NSCLC cells both in vitro and in vivo. Further high throughput analysis reveals that RAD51, a pivotal factor in homologous recombination repair, is a potential target for it. The following mechanism studies show that (-)-Guaiol is involved in cell autophagy to regulate the expression of RAD51, leading to double-strand breaks triggered cell apoptosis. Moreover, targeting RAD51, which is highly overexpressed in the lung adenocarcinoma tissues, can significantly increase the chemosensitivity of NSCLC cells to (-)-Guaiol both in vitro and in vivo. All in all, our studies provide an attractive insight in applying (-)-Guaiol into NSCLC treatments and further suggest that knockdown of oncogenic RAD51 will greatly enhance the chemosensitivity of patients with NSCLC.
Integrating Network Pharmacology, Molecular Docking, and Experimental Validation to Investigate the Mechanism of (-)-Guaiol Against Lung Adenocarcinoma
Med Sci Monit 2022 Jul 25;28:e937131.PMID:35871777DOI:10.12659/MSM.937131.
BACKGROUND Lung adenocarcinoma (LUAD) is the most common type of lung cancer, which poses a serious threat to human life and health. -(-)Guaiol, an effective ingredient of many medicinal herbs, has been shown to have a high potential for tumor interference and suppression. However, knowledge of pharmacological mechanisms is still lacking adequate identification or interpretation. MATERIAL AND METHODS The genes of LUAD patients collected from TCGA were analyzed using limma and WGCNA. In addition, targets of (-)-Guaiol treating LUAD were selected through a prediction network. Venn analysis was then used to visualize the overlapping genes, which were further condensed using the PPI network. GO and KEGG analyses were performed sequentially, and the essential targets were evaluated and validated using molecular docking. In addition, cell-based verification, including the CCK-8 assay, cell death assessment, apoptosis analysis, and western blot, was performed to determine the mechanism of action of (-)-Guaiol. RESULTS The genes included 959 differentially-expressed genes, 6075 highly-correlated genes, and 480 drug-target genes. Through multivariate analysis, 23 hub genes were identified and functional enrichment analyses revealed that the PI3K/Akt signaling pathway was the most significant. Experiment results showed that -(-)Guaiol can inhibit LUAD cell growth and induce apoptosis. Additional evidence suggested that the PI3K/Akt signaling pathway established an inseparable role in the antitumor processes of -(-)Guaiol, which is consistent with network pharmacology results. CONCLUSIONS Our results show that the effect of (-)-Guaiol in LUAD treatment involves the PI3K/Akt signaling pathway, providing a useful reference and medicinal value in the treatment of LUAD.
Microbial transformation of (-)-Guaiol and antibacterial activity of its transformed products
J Nat Prod 2007 May;70(5):849-52.PMID:17385913DOI:10.1021/np068052a.
Microbial transformation of the sesquiterpene (-)-Guaiol (1) [1(5)-guaien-11-ol] was investigated using three fungi, Rhizopus stolonifer, Cunninghamella elegans, and Macrophomina phaseolina. Fungal transformation of 1 with Rhizopus stolonifer yielded a hydroxylated product, 1-guaiene-9 beta,11-diol (2). In turn, Cunninghamella elegans afforded two mono- and dihydroxylated products, 1-guaiene-3beta,11-diol (3) and 1(5)-guaiene-3beta,9 alpha,11-triol (4), while Macrophomina phaseolina produced two additional oxidative products, 1(5)-guaien-11-ol-6-one (5) and 1-guaien-11-ol-3-one (6). All metabolites were found to be new compounds as deduced on the basis of spectroscopic techniques. Compounds 1-6 were evaluated for their activity against several bacterial strains.
