To isolate and identify new types of nitrogenous constituents from leaves of Moringa oleifera, as well as to further investigate their potential cytoprotective effects against H2O2-induced cellular injury, thirteen secondary metabolites were purified included one new nitrile glycoside (1), one new pyrrole alkaloid (2), and eleven nitrogenous phytoconstituents (3-13), determined based on chemical and spectroscopic data, such as 1D and 2D NMR, and mass spectra. Among them, the protective effects of compounds 1-13 on adrenal pheochromocytoma (PC12) cells exposed to hydrogen peroxide were evaluated. Compound 2 showed significant neuroprotective activity at concentrations of 1, 5, and 10 μM. Compounds 5 and 9 showed significant neuroprotective activity at concentrations of 5 and 10 μM. Compound 10 displayed significant neuroprotective activity against H2O2-induced cell damage at a concentration of 10 μM. In general, nitrogenous compounds from Moringa Oleifera leaves exhibited a potential cytoprotective effect against H2O2-induced cellular injury.
PURPOSE:Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide. Tumor-associated macrophages (TAMs) are key components of the immunosuppressive tumor microenvironment and represent significant obstacles to effective immunotherapy. Phyllanthus emblica L. (PE), a medicinal plant traditionally used in Tibet, has shown therapeutic promise. This study investigates the effects of the tannin fraction of PE (PE-TF) on HCC and its ability to modulate the tumor immunosuppressive microenvironment. METHODS:We evaluated the antitumor efficacy of PE-TF using H22 xenografts and Hepa1-6 orthotopic mouse models. Transcriptomic analysis was performed to identify molecular targets underlying PE-TF suppression of HCC growth. Additionally, UPLC-MS/MS analysis identified the prototypic and metabolic components of PE-TF present in serum, tumor tissues, and adjacent normal liver tissues in the orthotopic HCC model. RESULTS:PE-TF significantly suppressed tumor growth in both subcutaneous and orthotopic HCC models and promoted reprogramming of TAMs toward an antitumor M1 phenotype in vivo. Furthermore, PE-TF counteracted the protumoral effects mediated by bone marrow-derived macrophages (BMDMs) exposed to Hepa1-6-derived conditioned medium (HCM). Although TBH promoted macrophage M2 polarization, the reactive oxygen species (ROS)-scavenging activity of PE-TF effectively inhibited this process. Modulation of the tumor microenvironment by PE-TF-enhanced CD8+T cell infiltration and bolstered their antitumor response, as evidenced by increased transcription of perforin, IFN-γ, and IL-2. Transcriptomic analysis further revealed that T-cell receptor and cytotoxic T-cell signaling pathways are critical mediators of PE-TF' therapeutic effects. Moreover, we preliminarily characterized 79 components across serum, liver, and tumor tissues, and identified metabolic pathways for PE-TF ingredients-including methylation and glycosylation modifications of tumor-enriched constituents. Notably, seven components, such as corilagin and urolithin D, are hypothesized to possess immunomodulatory properties. CONCLUSION:Our findings underscore the potential of PE-TF as an adjuvant immunotherapy for HCC. By scavenging ROS, PE-TF reverses the immunosuppressive M2-TAM phenotype and remodels the tumor microenvironment, thereby enhancing antitumor immunity. Additionally, integrating chemical and metabolic profiling offers a promising strategy for refining candidate selection in future drug discovery endeavors.
Covering: 2009 up to the end of 2023Stilbenes, an emblematic group of polyphenols, have attracted the attention of numerous researchers owing to their intriguing polycyclic architectures and diverse bioactivities. In this updated review, natural stilbenes were analysed, especially oligomeric stilbenes, which are an emblematic group of polyphenols that harbor intriguing polycyclic architectures and diverse bioactivities compared with those previously anticipated. Oligomeric stilbenes with unique skeletons comprise a large majority of natural stilbenes owing to their structural changes and different substitutions on the phenyl rings. These compounds can be promising sources of lead compounds for studying new drugs and medicines. In addition, the exploration of unusual structures of oligomeric stilbenes such as polyflavanostilbenes A and B, analysing their absolute stereochemistry, and improving their yield using synthetic biology methods have recently gained interest. This review provides a systematic overview of 409 new stilbenes, which were isolated and identified over time from January 2009 to December 2023, focusing on the classification and biomimetic syntheses of oligomeric stilbenes, in addition to presenting meaningful insights into their structural diversity and biological activities, which will inspire further investigations of biological activities, structure-activity relationships, and screening of drug candidates.
BACKGROUND:Lung cancer is one of the deadliest cancers world-wide and immunotherapy has been considered as a promising therapeutic strategy. Previously, our study found that tannins in Phyllanthus emblica L. (PTF) could inhibit the growth of tumor by activating the immune response in liver cancer, and also exhibited a cytotoxicity on human lung cancer cells A549, H460, H1703 in vitro.OBJECTIVE:To explore whether PTF inhibited the growth of lung cancer through its immune-regulating function and to clarify underlying mechanisms.METHODS:The induction of immunogenic cell death (ICD) were characterized by calreticulin exposure, extracellular ATP secretion, and High Mobility Group Box 1(HMGB1) release both in vivo using LLC-derived xenograft tumor model and in vitro using both mouse LLC and human A549 cancer cells.RESULTS:PTF inhibited lung cancer cells growth and tumorigenesis in vivo/vitro and promoted anti-tumor immune responses. We further found that PTF could induce ICD, which then activated Type I interferon responses and CXCL9/10-mediated chemotaxis. Mechanistically, PTF induced the formation of intracellular protein aggregates and following activation of PERK/ATF4/CHOP-dependent endoplasmic reticulum stress-related ICD. Moreover, PTF improved the antitumor efficacy of cisplatin by inducing ICD both in vitro and in vivo. Finally, we screened out 5 components from PTF, including gallocatechin, gallic acid, methyl gallate, ethyl gallate and ellagic acid, which could induce ICD in vitro and might be considered as the potential antitumor pharmacodynamic substances.CONCLUSION:In conclusion, PTF inhibits the growth of lung cancer by triggering ICD and remodeling the tumor microenvironment, suggesting that PTF may have promising prospects as an adjacent immunotherapy for cancers.
Correction for ‘ Moringa oleifera leaf polysaccharides exert anti-lung cancer effects upon targeting TLR4 to reverse the tumor-associated macrophage phenotype and promote T-cell infiltration’ by Shukai Wang et al. , Food Funct. , 2023, 14 , 4607–4620, https://doi.org/10.1039/D2FO03685A.
The objective of the present study was to develop PTF-loaded solid lipid nanoparticles (PTF-SLNs) and investigate their efficacy in treating lung cancer. The PTF-SLNs were prepared by the thin film hydration method and verified by FTIR and TEM. Their physicochemical properties were characterized by particle size, polydispersity index (PDI), zeta potential, entrapment efficiency (EE), drug loading (DL), etc. Then, the pharmacodynamic studies of PTF-SLNs were performed on Lewis lung cancer cells and tumor-bearing mice. Finally, the safety studies were assessed by organ index, serum biochemical indicators, and histopathological changes. The PTF-SLNs were characterized by around 50 nm sphere nanoparticles, sustained ideal stability, and controlled drug release effects. The pharmacodynamic evaluation results showed that PTF-SLNs had stronger anti-tumor efficacy than PTF. An in vitro study revealed a more obvious cytotoxicity and apoptosis effect. The IC 50 values of PTF and PTF-SLNs were 67.43 μg/mL and 20.74 μg/mL, respectively. An in vivo study showed that the tumor inhibition rates of 2 g/kg PTF and 0.4 g/kg PTF-SLNs were 59.97% and 64.55%, respectively. The safety preliminary study indicated that PTF-SLNs improve the damage of PTF to normal organs to a certain extent. This study provides a nanoparticle delivery system with phenolic herbal extract to improve anti-tumor efficacy in lung cancer.

Tumor-associated macrophages (TAMs) participate in tumorigenesis, growth, invasion as well as metastasis by facilitating an immunosuppressive tumor microenvironment. Reversing the pro-tumoral M2 phenotype of TAMs has become a hot spot in advancing cancer immunotherapy. In the current study, the content of Moringa oleifera leaf polysaccharides (MOLP) was determined and characterized, along with the anti-cancer mechanism of MOLP studied in a Lewis lung cancer (LLC) tumor-bearing mouse model and bone marrow-derived macrophages. The monosaccharide composition and gel permeation chromatography analyses show that MOLP are mainly composed of galactose, glucose, and arabinose, with approximately 17.35 kDa average molecular weight (Mw). In vivo studies demonstrate that MOLP convert TAMs from the immunosuppressive M2 phenotype to the antitumor M1 phenotype, thus inducing CXCL9 and CXCL10 expression and increasing T-cell infiltration in the tumor. Furthermore, macrophage depletion and T cell suppression demonstrated that the tumor suppressive effect of MOLP was reliant on reprogramming macrophage polarization and T cell infiltration. In vitro studies revealed that MOLP could induce the phenotypic switch from M2 macrophages to M1 by targeting TLR4. The current study highlights that MOLP are promising anticancer plant-derived polysaccharides with potential in modulating the immune microenvironment and have a bright application prospect in the immunotherapy of lung cancer.
Elucidating the underlying mechanism of the processing of Chinese herbal medicine (CHM) is crucial and also challenging for the modernization of Traditional Chinese Medicine (TCM). Herein, inspired by the traditional method for processing the Chinese herb Polygonum multiflorum (PM) Thunb with excipient black beans, the representative herbal components trans-2,3,5,4'-tetrahydroxystilbene 2-O-β-D-glucopyranoside (TSG) and cyanidin-3-O-β-glucoside (C3G) from each herbal medicine were selected to investigate the processing mechanism at the supramolecular level. The co-assemblies of TSG/C3G were found to be formed, and their structure was characterized by electronic microscopy and a small angle X-ray scattering (SAXS) technique. In addition, the supramolecular interactions between TSG and C3G were fully probed with UV-Vis, fluorescence, XRD, and NMR spectroscopy. Molecular dynamics were further performed to simulate the assembly processes of TSG and C3G. Notably, the formation of TSG/C3G co-assemblies was found to significantly enhance the stability of TSG against light, Fe3+, and simulated intestinal fluids. The co-assembly of TSG and C3G that leads to supramolecular aggregates discovered here may imply the underlying mechanism of processing PM with black beans. Our results may also suggest that a new effective form of TCM is supramolecular aggregates rather than each component.

Background:There is growing evidence to suggest that ginsenoside Rd (GRd) has a therapeutic effect on depression, but the specific mechanisms behind its activity require further study.Objective:This study is designed to investigate the antidepressant-like effect and underlying mechanisms of GRd.Methods:In this study, the behavioral despair mouse model of depression and chronic unpredictable mild stress (CUMS) rat model of depression were established to explore the effects of GRd on depression-like behavior and its underlying mechanisms. Behavioral tests were used to evaluate the replication of animal models and depression-like behaviors. The hypoxia-inducible factor-1α (HIF-1α) blocker 2-methoxyestradiol (2-ME) was injected to determine the role of HIF-1α in the antidepressant-like effect of GRd. In addition, molecular biology techniques were used to determine the mRNA and protein expression of HIF-1ɑ signaling pathway and synaptic plasticity-related regulators, that is synapsin 1 (SYN 1) and postsynaptic density protein 95 (PSD 95). In silico binding interaction studies of GRd with focused target proteins were performed using molecular docking to predict the affinity and optimal binding mode between ligands and receptors.Results:Our data show that GRd significantly reversed depression-like behavior and promoted mRNA and protein expression of HIF-1ɑ signaling pathway and synaptic plasticity-related regulators. However, the antidepressant-like effect of GRd disappeared upon inhibition of HIF-1α expression following administration of 2-ME. Furthermore, molecular docking results showed that GRd possessed significant binding affinity for HIF-1α, VEGF, and VEGFR-2.Conclusion:Our results show that GRd exhibits significant antidepressant-like effect and that HIF-1α signaling pathway is a promising target for the treatment of depression.

The aim of this study is to evaluate the anti-hyperuricemia effect and clarify the possible mechanisms of flavonoids and phenolics of MOL (MOL-FP) in mice. Hyperuricemia mice were generated via intraperitoneal (i.p.) administration of potassium oxonate (PO) and oral gavage (p.o.) of hypoxanthine (HX). Serum uric acid (UA), weight, serum XO activity, hepatic XO activity, urea nitrogen (BUN), creatinine (CRE), serum AST level, serum ALT level, mRNA expression of renal urate-anion transporter 1 (URAT1), glucose transporter 9 (GLUT9), organic anion transporters 1 (OAT1), organic anion transporters 3 (OAT3), and ATP-binding cassette transporter G2 (ABCG2) were determined. The molecular docking was conducted using AutoDock Vina 1.2.0 to screen potential XO inhibitors in MOL-FP. Serum metabolomics was established to collect the metabolic profiles of mice and explore the metabolic changes that occurred after MOL-FP treatment. MOL-FP could notably reduce the serum UA level of hyperuricemia mice by inhibiting XO activity and regulating renal urate transporters. Molecular docking studies indicated that 5-p-coumaroylquinic acid, 3-p-coumaroylquinic acid, and catechin could be potential XO inhibitors. Besides, MOL-FP prevented the pathological process of hyperuricemia by regulating biomarkers associated with purine metabolism, amino acid metabolism, and lipid metabolism.

Tumor-associated macrophages (TAMs) are the major immunosuppressive components infiltrating the tumor microenvironment (TME). Targeting TAMs has emerged as a promising strategy to remodel immunosuppressive TME and enhance T-cell mediated anti-tumor immunity for cancer therapy. In this study, we investigate the effect and mechanism of total tannin fraction of Terminalia bellirica (Gaertn.) Roxb. (TB-TF) against hepatocellular carcinoma (HCC) using established Hepa1–6 orthotopic mouse model and murine bone marrow derived macrophage polarization model. Here we showed that TB-TF significantly inhibited orthotopic tumor growth and promoted the polarization of M2-TAMs toward the anti-tumor M1 phenotype in vivo. Further studies showed that TB-TF reversed tumor-conditioned medium induced M2 polarization of macrophages as indicated by increased expression of TNF-α, IL-1β, and iNOS, and decreased expression of Arg-1, thereby re-educating macrophages co-cultured with tumor-conditioned medium into M1 phenotype. In addition, we found that TB-TF also promoted T cell infiltration mediated by chemokines such as CCL5 and CXCL10, and restored the cytotoxic function of CD8+T cells as evidenced by upregulated expression of Granzyme B, Perforin, and IFN-γ. Our data suggest TB-TF as a promising anti-cancer agent, mediates its anti-tumor effects via remodeling the tumor immunosuppressive microenvironment, indicating its potential in the immunotherapy for hepatocellular carcinoma.
