Cancer metastasis is a serious threat to human health. Cancer stem cells (CSC) are closely related to tumor metastasis, but it is difficult to achieve accurate drug delivery and effective inhibition of CSC due to the complex tumor microenvironment. Herein, we report a living cell delivery system, C-H@M2, engineered by loading M2 macrophages with carrier-free Ce6/Honokiol self-assembled nanoparticles. This system is designed to harness the tumor’s intrinsic recruitment mechanism for targeted anti-metastasis therapy. Acting as a “Trojan Horse”, C-H@M2 exploits the active recruitment of M2 macrophages by CSC to achieve precise tumor homing. Upon laser irradiation, the macrophages undergo photo-triggered immunogenic lysis (“self-explosion”), leading to the burst release of therapeutic payloads and the induction of robust immunogenic cell death (ICD). HK as an inhibitor of Forkhead box M1 (FOXM1) inhibits CSC stemness and epithelial mesenchymal transition (EMT) in tumor tissues. In vivo experimental results demonstrate that C-H@M2 significantly inhibits tumor and lung metastasis through a triple-modal strategy: Self-explosion enhanced ICD effect, stemness and EMT inhibition, CSC killing by stemness inhibition and PDT. Our study provides a novel strategy for CSC targeted therapy and cancer metastasis inhibition. Graphical

Porcine reproductive and respiratory syndrome (PRRS) is a highly contagious swine disease and poses a severe economic burden to the global swine industry. Owing to the inadequacy of current prevention and control measures, developing effective antiviral strategies for preventing PRRS epidemics is imperative. Honokiol (HNK) is a bioactive component of the dietary supplement magnolia extract. Here, we demonstrated that HNK exhibited potent antiviral effects against different PRRSV strains in vitro. Mechanistically, HNK was shown to interfere with PRRSV replication rather than attachment, internalization, or release. HNK was further determined to target PRRSV RNA-dependent RNA polymerase to impair viral genomic RNA synthesis. In addition, HNK was found to decrease PRRSV-triggered inflammatory responses. More importantly, HNK was revealed to reduce viral loads and alleviate lung damage in vivo. This study highlights the potential of HNK as an inhibitor of PRRSV and provides novel insights into its antiviral properties.

Diabetes mellitus (DM) is a chronic disease influenced by gut microbiome disturbances. Honokiol (HON), a low oral bioavailability compound from Magnolia officinalis bark, has demonstrated potential as a treatment for DM. This research investigates the effects of HON on gut microbiota and host metabolism to elucidate its mechanism of action in DM. After 8 weeks of intervention through fecal microbiota transplantation (FMT) or antibiotic treatment, HON improved glucose tolerance and lipid metabolism in a gut microbiota-dependent manner. Specifically, HON administration significantly increased Akkermansia muciniphila (AKK) abundance and modulated tryptophan (TRP) metabolism, as evidenced by 16S ribosomal ribonucleic acid (rRNA) gene sequencing and untargeted/targeted metabolomics analysis. Notably, research revealed that AKK metabolized TRP into tryptamine (TA) and other metabolites in vitro . Both AKK and TA activated the aryl hydrocarbon receptor (AHR) pathway, increasing circulating glucagon-like peptide-1 (GLP-1) levels and ameliorating diabetes-related symptoms in DM mice. These findings indicate that HON’s hypoglycemic effect primarily stems from AHR-GLP-1 pathway activation through targeted modulation of AKK and microbial TRP metabolite TA, potentially enhancing HON’s clinical applications.

Many kinds of antibacterial coatings have been designed to prevent the adherence of bacteria onto the surface of a fixed orthodontic device of brackets. However, the problems such as weak binding force, undetectable, drug resistance, cytotoxicity and short duration needed to be solved. Thus, it has great value in developing novel coating methods with long-term antibacterial and fluorescence properties according to the clinical application of brackets. In this study, we synthesized blue fluorescent carbon dots (HCDs) using the traditional Chinese medicinal honokiol, which could cause irreversible killing effects on both gram-positive and gram-negative bacteria through positive charges on the surface and inducing reactive oxygen species (ROS) production. Based on this, the surface of brackets was serially modified with polydopamine and HCDs, taking advantage of the strong adhesive properties as well as the negative surface charge of polydopamine particles. It is found that this coating exhibits stable antibacterial properties in 14 days with good biocompatibility, which can provide a new solution and strategy to solve the series of hazards caused by bacterial adhesion on the surface of orthodontic brackets.

BACKGROUND Kiwifruit rot is an important disease caused by different fungal pathogens, which can lead to huge economic loss in the kiwifruit industry. The aims of this study were to discover an effective botanical compound that significantly inhibits the pathogens causing kiwifruit rot, evaluate its control efficacy against this disease, and reveal the underlying mechanisms. RESULTS A strain of Fusarium tricinctum (GF-1), isolated from diseased kiwifruit, could cause fruit rot in both Actinidia chinensis var. chinensis and Actinidia chinensis var. deliciosa . Different botanical chemicals were used for antifungal activity test against GF-1 and thymol was the most effective one with a 50% effective concentration (EC 50 ) of 30.98 mg L −1 . The minimal inhibitory concentration (MIC) of thymol against GF-1 was 90 mg L −1 . Control efficacy of thymol against kiwifruit rot was evaluated and the results indicated that thymol could effectively decrease the occurrence and spread of kiwifruit rot. The mechanisms underlying the antifungal activity of thymol against F. tricinctum were investigated, and it showed that thymol could significantly damage the ultrastructure, destroy the plasma membrane integrity, and instantaneously increase energy metabolisms of F. tricinctum . Further investigations indicated that thymol could extend shelf life of kiwifruit by increasing their storability. CONCLUSION Thymol can effectively inhibit F. tricinctum that is one of the causal agents of kiwifruit rot. Multiple modes of action are involved in the antifungal activity. The results of this study indicate that thymol can be a promising botanical fungicide to control kiwifruit rot and provide useful references for thymol application in agriculture system. © 2023 Society of Chemical Industry.

Alzheimer's Dementia (AD) and Vascular Dementia (VaD) are two main types of dementias for which no specific treatment is available. Chronic Cerebral Hypoperfusion (CCH) is a pathogenesis underlying AD and VaD that promotes neuroinflammatory responses and oxidative stress . Honokiol (HNK) is a natural compound isolated from magnolia leaves that can easily cross blood brain barrier and has anti-inflammatory and antioxidant effects. In the present study, the effects of HNK on astrocyte polarization and neurological damage in in vivo and in vitro models of chronic cerebral hypoperfusion were explored. We found that HNK was able to inhibit the phosphorylation and nuclear translocation of STAT3 , A1 polarization, and reduce conditioned medium's neuronal toxicity of astrocyte under chronic hypoxia induced by cobalt chloride ; STAT3 phosphorylation inhibitor C188-9 was able to mimic the above effects of HNK, suggesting that HNK may inhibit chronic hypoxia-induced A1 polarization in astrocytes via STAT3. SIRT3 inhibitor 3-TYP reversed, while Sirt3 overexpression mimicked the inhibitory effects of HNK on oxidative stress, STAT3 phosphorylation and nuclear translocation, A1 polarization and neuronal toxicity of astrocyte under chronic hypoxic conditions. For in vivo research, continuous intraperitoneal injection of HNK (1 mg/kg) for 21 days ameliorated the decrease in SIRT3 activity and oxidative stress, inhibited astrocytic STAT3 nuclear translocation and A1 polarization, and prevented neuron and synaptic loss in the hippocampal of CCH rats. Besides, HNK application improved the spatial memory impairment of CCH rats, as assessed with Morris Water Maze . In conclusion, these results suggest that the phytochemical HNK can inhibit astrocyte A1 polarization via regulating SIRT3-STAT3 axis, thus improving CCH-induced neurological damage. These results highlight HNK as novel treatment for dementia with underlying vascular mechanisms.

Preparing biobased thermosetting resins with high mechanical properties and superior heat resistance is an important issue for the sustainable development and applications of high performance resins. Herein, a novel biobased allyl compound (DBB) with aryl propargyl ether groups was synthesized from renewable honokiol , which was then used to copolymerize with 4,4′-bismaleimidodiphenylmethane (BDM) to develop new biobased resins (BDM/DBB). The effects of the molar ratio of BDM to DBB on the thermal and mechanical properties were studied. Results show that all BDM/DBB resins possess both high thermal and mechanical properties. Specifically, their glass transition temperatures ( T g > 440 °C) and storage moduli (> 1.3 GPa at 400 °C) are higher than those of biobased allyl compounds modified BDM resins reported so far (SCI database); moreover, their initial thermal decomposition temperatures are about 448 °C and flexural strengths range from 106 to 117 MPa. These excellent comprehensive performances are attributed to the unique crosslinked network resulted from the complex curing mechanism of BDM/DBB, which including the copolymerization between imide groups and allyl groups as well as the additional thermal crosslinking of aryl propargyl ether. This work provides a sustainable and facile strategy to construct high performance biobased resins.

Bacterial infection, oxidative stress and inflammation are the main obstacles in wound healing. Hydrogels with moist and inherent properties are beneficial to wound healing. Here, we fabricated a honokiol-laden micelle-crosslinked hyaluronate-based hydrogel by simply mixing honokiol-laden PF127-CHO micelles, 3,3′-dithiobis(propionohydrazide) grafted hyaluronic acid and silver ions. PF127 could not only effectively load hydrophobic small molecules but also be macromolecular crosslinker for preparing hydrogels. Hyaluronic acid plays an essential role in wound healing processes including regulating macrophage polarization towards M2 phenotype. The chemical dynamic acylhydrazone crosslinking and physical crosslinking among PF127-CHO micelles constructed hydrogel's networks, which endowed hydrogel with excellent self-healing properties. PF-HA-3 hydrogel also exhibited outstanding antioxidant and antibacterial capabilities. In a full-thickness skin defect model, this degradable and biocompatible hydrogel could promote wound healing by remodeling wound tissues, regulating M2 polarization and angiogenesis . In summary, this inherent multifunctional hydrogel will provide a promising strategy for designing bioactive compounds-based wound dressings.

Bacterial infections severely threaten human health; therefore, it is important to endow the matrix for tissue engineering with antibacterial efficiency. The loading of antibacterial drugs on nanomaterials provides an efficient strategy to realize synergistic antibacterial efficiency. By depositing various metal–organic frameworks, such as UIO-66, onto konjac glucomannan (KGM), composite hydrogels (KGM/UIO-66) were created. These hydrogels were used as drug carriers, enabling the development of antibacterial hydrogels with high drug loading capacities (e.g., the maximum loading amount of pterostilbene on KGM/UIO-66 reached 0.157 mg/mg) and sustained drug release. The resulting KGM/UIO-66/pterostilbene hydrogel exhibited a three-dimensional porous structure, excellent biocompatibility, antibacterial efficiency, and anti-inflammatory activity. It effectively protected cells from bacterial attacks while ensuring cell adhesion and proliferation, demonstrating great potential as a three-dimensional substrate for biomedical applications, including tissue engineering and regenerative medicine.

Schwann cells injury induced by high glucose (HG) contributes to the development of diabetic peripheral neuropathy (DPN). Honokiol has been reported to regulate glucose metabolism, however, its effect on DPN and the precise molecular mechanisms remain unclear. This study aimed to investigate the role of AMPK/SIRT1/PGC-1α axis in the protective effects of honokiol on DPN. The biochemical assay and JC-1 staining results demonstrated that honokiol reduced HG-induced oxidative stress and ferroptosis as well as mitochondrial dysfunction in Schwann cells. RT-qPCR and western blotting were utilized to investigate the mechanism of action of honokiol, and the results showed that HG-induced inhibition of AMPK/SIRT1/PGC-1α axis and changes of downstream gene expression profile were restored by honokiol. Moreover, silencing of Sirt1 by siRNA delivery markedly diminished the changes of gene expression profile induced by honokiol in HG-induced Schwann cells. More importantly, we found that administration of honokiol remarkably attenuated DPN via improving sciatic nerve conduction velocity and increasing thermal and mechanical sensitivity in streptozotocin-induced diabetic rats. Collectively, these results demonstrate that honokiol can attenuate HG-induced Schwann cells injury and peripheral nerve dysfunction, suggesting a novel potential strategy for treatment of DPN.

The prevalence of acne vulgaris is high, but the topical retinoids used as the foundation of treatment have teratogenic and photosensitivity properties. Previous studies have suggested that honokiol, a small-molecule compound extracted from Magnolia officinalis, could effectively inhibit Cutibacterium acnes (C acnes) and inflammation in vitro. However, the effect in vivo is unclear. The rabbit ear acne model that we created showed obvious comedones and hyperkeratosis. These lesions were repeatedly measured and recorded by dermatoscopy (ultraviolet light). Compared with the control group, topical 2.5% honokiol cream obviously improved the comedones and hyperkeratosis and effectively reduced sebum secretion, as shown by Oil Red O staining. The effects were equivalent to those of adapalene gel without local side effects. We added honokiol's other functions to acne treatment in addition to antiinflammation, but further studies are needed.

Cadmium (Cd) pollution in environment is toxic to birds. This study aimed to assess antagonistic effect of honokiol (HNK) on Cd-induced quail ( Coturnix japonica ) liver tissue damage and Cd-induced vacuolation in hepatocytes. We found that HNK alleviated Cd-induced liver pathological damage marked by elevated serum liver biochemical indicators, disordered antioxidant levels and trace elements in quails. HNK reduced Cd-induced liver cell apoptosis as assessed by western blotting and TUNEL staining. The ultrastructure of hepatocytes under transmission electron microscope revealed that Cd induced mitochondrial damage in addition to abnormal enlargement and increased vacuolar structure of cells. Mitochondrial damage and vacuolization were reduced in the HNK + Cd group. Cd induced an increase in the levels of endosomal/lysosomal-related genes, while HNK treatment reversed this effect. Finally, we demonstrated that vacuolation in buffalo rat liver 3A (BRL 3A) cells occurred primarily due to Cd-induced oxidative stress damage that reduces mitochondrial ATP content and indirectly led to dysfunction of ATP-dependent lipid kinase PIKfyve complex. In summary, we are the first to report that Cd induces abnormal enlargement of endosome/lysosomes in quail liver cells and HNK alleviated this phenomenon by reducing mitochondrial damage and increasing intracellular ATP level. This study demonstrated the toxic effect of Cd pollution on birds and how HNK mitigated these effect at the cellular level. Overall, more research on Cd pollution and HNK use in animal husbandry is warranted.
