Piperine: an emerging biofactor with anticancer efficacy and therapeutic potential

Anticancer drug discovery needs serious attention to overcome the high mortality rate caused by cancer. There are still many obstacles to treating this disease, such as the high cost of chemotherapeutic drugs, the resulting side effects from the drug, and the occurrence of multidrug resistance. Herbaceous plants are a reservoir of natural compounds that can be anticancer drugs with novel mechanisms of action. Piperine, a bioactive compound derived from Piper species, is gaining attention due to its unique dual role in directly inhibiting tumor growth and enhancing the bioavailability of chemotherapeutic drugs. Unlike conventional treatments, Piperine exhibits a novel mechanism of action by modulating multiple signaling pathways, including apoptosis and autophagy, with low toxicity. Additionally, Piperine acts as a bioenhancer by improving the absorption and effectiveness of other anticancer agents, reducing the required dosage, and minimizing side effects. Therefore, this review aims to visualize a summary of Piperine sources, phytochemistry, chemical structure-anticancer activity relationship, anticancer activities of semi-synthetic derivatives, pharmacokinetic and bioavailability, in vitro and in vivo preclinical studies, mechanism of antitumor action, human clinical trials, toxicity, side effects, and safety of Piperine. References were collected from the Pubmed/MedLine database (https://pubmed.ncbi.nlm.nih.gov/) with the following keywords: "Piperine anticancer," "Piperine derivatives," "Piperine antitumor mechanism" and "Piperine pharmacokinetic and bioavailability," after filter process by inclusion and exclusion criteria, 101 were selected from 444 articles. From 2013 to 2023, there were numerous studies regarding preclinical studies of Piperine of various cell lines, including breast cancer, prostate cancer, lung cancer, melanoma, cervical cancer, gastric cancer, osteosarcoma, colon cancer, hepatocellular carcinoma, ovarian cancer, leukemia, colorectal cancer, and hypopharyngeal carcinoma. In vivo, the anticancer study has also been conducted on some animal models, such as Ehrlich carcinoma-bearing mice, Ehrlich ascites carcinoma cells-bearing Balbc mice, hepatocellular carcinoma-bearing Wistar rat, A375SM cells-bearing mice, A375P cells-bearing mice, SNU-16 cells-bearing BalbC mice, and HGC-27-bearing baby mice. Treatment with this compound leads to cell proliferation inhibition and induction of apoptosis. Piperine has been used for clinical trials of diseases, but no cancer patient report exists. Various semi-synthetic derivatives of Piperine show efficacy as an anticancer drug across multiple cell lines. Piperine shows promise for use in cancer clinical trials, either as a standalone treatment or as a bioenhancer. Its bioenhancer properties may enhance the efficacy of existing chemotherapeutic agents, providing a valuable foundation for developing new anticancer therapies.

Betanin inspired zinc oxide nanoparticles: The potential antioxidant and anticancer activity against human lung cancer cell line (A549)

BACKGROUND INFORMATION

Lung cancer is the most frequently reported disease on a global scale. The bioactive substances are less successful in specifically destroying cancer cells. To prevent early inactivation and ensure targeted delivery of bioactive chemicals to cancer cells. Betanin is known as nitrogenous water-soluble molecule which possess anti-inflammatory, hepatoprotective, antioxidant, and anticancer properties.

AIM OF THE STUDY

This work evaluates the anti-cancer and anti-oxidant properties of Betanin coated zinc oxide nanoparticles on the A549 lung cancer cell line.

MATERIALS AND METHODS

In the current work, Betanin coated Zinc oxide nanoparticles (Betanin coated ZnO NPs) were made utilizing Betanin, a phytochemical. SEM, FTIR, DLS, and UV-Vis were used to evaluate their properties. Trypan blue and MTT were used to confirm cell survival and cytotoxicity of ZnO nanoparticles at various dosages. The morphological evaluation of A549 cells was investigated by phase contrast microscopy and apoptosis by propidium iodide staining. The membrane integrity of mitochondria was investigated by rhodamine 123 staining and observed under fluorescence microscope. The anti-oxidant ability of ZnO nanoparticles was analyzed by level of catalase, glutathione, nitric oxide, lipid peroxidation, and superoxide dismutase using UV spectrophotometric analysis. Studies on gene expression (Bcl2, P53and BAX) were conducted to assess the molecular mechanism of apoptosis mediated by synthesized nanoparticle and level of matrix metalloproteinase -2 (MMP-2) by gelatin zymography.

RESULTS

At the peak of 383 nm in the UV band, zinc oxide NP synthesis was confirmed. The FT-IR data demonstrated that zinc oxide nanoparticles were effectively coated with Betanin and by dynamic light scattering analysis confirmed particle size to be 100.8 nm. The presence of cubic, spherical, and platelet-shaped zinc oxide nanoparticles has been observed by SEM analysis. The nanoparticles of zinc oxide (ZnO) were synthesized chemically and exhibited decreasing cell viability and increasing cytotoxicity and apoptosis in dose dependent manner. The levels of LPO activity increased significantly and NO, antioxidant enzymes (GSH, SOD, and CAT) activity decreased significantly (P <0.0001). Our results demonstrated that A549 cells treated with Betanin loaded ZnO nanoparticles to prevent oxidation by scavenging free radicals and increased levels of gene expression related to apoptotic proteins BAX, p53 and decreased level of expression in Bcl2. Further, level of matrix metalloproteinase -2 (MMP-2) decreased with increase in concentration of nanoparticle.

CONCLUSION

As per the research described above, lung cancer cells were effectively targeted by the anticancer and antioxidant abilities of ZnO nanoparticles inspired by Betanin (A549).

Beetroot extract@chitosan nanocomposite as a promising approach towards cancer therapy

The exceptional antioxidant properties of beetroot (BR) and the cancer antiproliferative effects of chitosan nanoparticles (CS NP) have led to the synthesis of a BR@CS nanocomposite (NC) in this study. The novel BR@CS NC was applied to human epithelial colorectal adenocarcinoma (Caco-2), human epithelial ductal breast carcinoma (T-47D), and human epithelial lung carcinoma (A549) cells. SEM characterization of CS NP revealed a variety of particle shapes ranging from 20 to 58 nm in diameter. UV-VIS analysis confirmed the formation of the BR@CS NC, while FTIR analysis demonstrated strong hydrogen bonds between CS NP and BR. These bonds reduced the positive surface charge of CS NP, as indicated by zeta potential analysis. When applied to cancer cell lines at a concentration of 250 μg/mL, the BR@CS NC successfully eradicated 89 % of A549, 88 % of T-47D, and 83 % of Caco-2 cell lines. The cell death mode exhibited extensive, apoptotic, and massive necrotic changes in all cell lines treated with BR@CS NC. Caspase 3 (CasP3) and P53 levels were elevated in BR@CS NC-treated cells. This study merges BR's antioxidant and anti-inflammatory properties with the antiangiogenic mechanism and inhibition of tumors by CS NP, resulting in a unique and innovative strategy for cancer treatment.

Cinnamaldehyde as a Promising Dietary Phytochemical Against Metabolic Syndrome: A Systematic Review

BACKGROUND

Metabolic syndrome (METS) is a set of unhealthy medical conditions considered essential health problems today. Cinnamaldehyde (CA) is the major phytochemical present in the essential oil of cinnamon and possesses antioxidant, anti-inflammatory, hypoglycemic, and antihyperlipidemic activities.

AIM

We aim to systematically review the effects of CA in preventing and attenuating METS components. Moreover, the cellular and molecular mechanisms of actions of CA, its pharmacokinetics features, and potential structure-activity relationship (SAR) were also surveyed.

METHODS

PubMed, Science Direct, Scopus, and Google Scholar were searched to retrieve the relevant papers.

RESULTS

CA possesses various anti-METS activities, including anti-inflammatory, antioxidant, antidiabetic, antidyslipidemia, antiobesity, and antihypertensive properties. Various molecular mechanisms such as stimulating pancreatic insulin release, exerting an insulinotropic effect, lowering lipid peroxidation as well as pancreatic islet oxidant and inflammatory toxicity, increasing the activities of pancreatic antioxidant enzymes, suppressing pro-inflammatory cytokines production, regulating the molecular signaling pathways of the PPAR-γ and AMPK in preadipocytes and preventing adipocyte differentiation and adipogenesis are involved in these activities.

CONCLUSIONS

CA would effectively hinder METS; however, no robust clinical data supporting these effects in humans is currently available. Accordingly, conducting clinical trials to evaluate the efficacy, safe dosage, pharmacokinetics characteristics, and possible unwanted effects of CA in humans would be of great importance.

Anticancer properties of red beetroot hydro-alcoholic extract and its main constituent; betanin on colorectal cancer cell lines

Colorectal cancer (CRC) is the third most common type of cancer worldwide. Red beetroot (Beta vulgaris) contains Betanin as its major betacyanin, possessing wide proapoptotic effects. This study aimed to investigate the anticancer and pro-papoptotic effects of beetroot hydro-alcoholic extract (BHE) and betanin, on colorectal cancer cell lines. BHE and betanin were used to treat Caco-2 and HT-29 colorectal cancer cells. MTT assay, DAPI staining, and FACS-flow cytometry tests were used to determine the half-maximal inhibitory concentration (IC50) and apoptosis-inducing evaluations. Intended genes were assessed by real-time polymerase chain reaction (RT-PCR). The IC50 for HT-29 and Caco-2 cell lines were 92 μg/mL, 107 μg/mL for BHE, and 64 μg/mL, 90 μg/mL for betanin at 48 h, respectively. BHE and betanin significantly inhibited the growth of both cancer cell lines time and dose-dependently. DAPI staining and flow cytometry results revealed significant apoptosis symptoms in treated cancerous cell lines. The expression level of proapoptotic genes (BAD, Caspase-3, Caspase-8, Caspase-9, and Fas-R) in treated HT-29 and Caco-2 cells was higher than in untreated and normal cells. In contrast, the anti-apoptotic gene (Bcl-2) was significantly downregulated. BHE and betanin effectively inhibited cancer cell proliferation and induced apoptosis via the modification of effective genes.

Effect of Ginger on Inflammatory Diseases

Ulcerative colitis, Crohn's disease, rheumatoid arthritis, psoriasis, and lupus erythematosus are some of common inflammatory diseases. These affections are highly disabling and share signals such as inflammatory sequences and immune dysregulation. The use of foods with anti-inflammatory properties such as ginger (Zingiber officinale Roscoe) could improve the quality of life of these patients. Ginger is a plant widely used and known by its bioactive compounds. There is enough evidence to prove that ginger possesses multiple biological activities, especially antioxidant and anti-inflammatory capacities. In this review, we summarize the current knowledge about the bioactive compounds of ginger and their role in the inflammatory process and its signaling pathways. We can conclude that the compounds 6-shoagol, zingerone, and 8-shoagol display promising results in human and animal models, reducing some of the main symptoms of some inflammatory diseases such as arthritis. For lupus, 6-gingerol demonstrated a protective attenuating neutrophil extracellular trap release in response to phosphodiesterase inhibition. Ginger decreases NF-kβ in psoriasis, and its short-term administration may be an alternative coadjuvant treatment. Ginger may exert a function of supplementation and protection against cancer. Furthermore, when receiving chemotherapy, ginger may reduce some symptoms of treatment (e.g., nausea).

The Role of Natural Products as Inhibitors of JAK/STAT Signaling Pathways in Glioblastoma Treatment

The permeability of glioblastoma, as well as its escaping the immune system, makes them one of the most deadly human malignancies. By avoiding programmed cell death (apoptosis), unlimited cell growth and metastatic ability could dramatically affect the immune system. Genetic mutations, epigenetic changes, and overexpression of oncogenes can cause this process. On the other hand, the blood-brain barrier (BBB) and intratumor heterogeneity are important factors causing resistance to therapy. Several signaling pathways have been identified in this field, including the Janus tyrosine kinase (JAK) converter and signal transducer and activator of transcription (STAT) activator pathways, which are closely related. In addition, the JAK/STAT signaling pathway contributes to a wide array of tumorigenesis functions, including replication, anti-apoptosis, angiogenesis, and immune suppression. Introducing this pathway as the main tumorigenesis and treatment resistance center can give a better understanding of how it operates. In light of this, it is an important goal in treating many disorders, particularly cancer. The inhibition of this signaling pathway is being considered an approach to the treatment of glioblastoma. The use of natural products alternatively to conventional therapies is another area of research interest among researchers. Some natural products that originate from plants or natural sources can interfere with JAK/STAT signaling in human malignant cells, also by stopping the progression and phosphorylation of JAK/STAT, inducing apoptosis, and stopping the cell cycle. Natural products are a viable alternative to conventional chemotherapy because of their cost-effectiveness, wide availability, and almost no side effects.

Protective effects of functional foods against Parkinson's disease: A narrative review on pharmacology, phytochemistry, and molecular mechanisms

In Persian Medicine (PM), PD (brain-based tremor) is a known CNS disorder with several therapeutic and preventive options. In their medical textbooks and pharmacopeias, Persian great scientists such as Rhazes (854-925 AD), Avicenna (980-1037 AD), and Jorjani (1042-1136 AD), have discussed pharmacological and nutritional strategies for the prevention, slowing progression, and treatment of PD. In the present study, we surveyed plant- and animal-based foods recommended by PM for the prevention and treatment of CNS-related tremors. In vivo and in-vitro pharmacological evidence supporting the beneficial effects of PM-recommended foods in prevention and alleviating PD, major active phytochemicals along with the relevant mechanisms of action were studied. Several PM plants possess potent antioxidant, antiinflammatory, and PD preventing properties. Garlic and allicin, cabbage and isothiocyanates, chickpea seed and its O-methylated isoflavones biochanin A and formononetin, cinnamon, and cinnamaldehyde, saffron and its crocin, crocetin, and safranal, black cumin and its thymoquinone, black pepper and piperine, pistachio and genistein and daidzein, and resveratrol are among the most effective dietary itemsagainst PD. They act through attenuating neurotoxin-induced memory loss and behavioral impairment, oxidative stress, and dopaminergic cell death. PM-recommended foods can help alleviate PD progression and also discovering and developing new neuroprotective anti-PD pharmaceuticals.

Novel cinnamon-laden nanofibers as a potential antifungal coating for poly(methyl methacrylate) denture base materials

OBJECTIVES

To modify the surface of denture base material by coating it with cinnamon-laden nanofibers to reduce Candida albicans (C. albicans) adhesion and/or proliferation.

MATERIALS AND METHODS

Heat-cured poly(methyl methacrylate) (PMMA) specimens were processed and coated, or not, with cinnamon-laden polymeric nanofibers (20 or 40 wt.% of cinnamon relative to the total polymer weight). Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) analyses of the nanofibers were performed. Antifungal activity was assessed through agar diffusion and colony-forming unit (CFU/mL) assays. Representative SEM morphological analysis was carried out to observe the presence/absence of C. albicans on the fibers. Alamar blue assay was used to determine cell toxicity. Analysis of variance and the Tukey's test were used to analyze the data (α = 0.05).

RESULTS

SEM imaging revealed nanofibers with adequate (i.e., bead-free) morphological characteristics and uniform microstructure. FTIR confirmed cinnamon incorporation. The cinnamon-laden nanofibers led to growth inhibition of C. albicans. Viable fungal counts support a significant reduction on CFU/mL also directly related to cinnamon concentration (40 wt.%: mean log 6.17 CFU/mL < 20 wt.%: mean log 7.12 CFU/mL), which agrees with the SEM images. Cinnamon-laden nanofibers at 40 wt.% led to increased cell death.

CONCLUSIONS

The deposition of 20 wt.% cinnamon-laden nanofibers onto PMMA surfaces led to a significant reduction of the adhesive and/or proliferative ability of C. albicans, while maintaining epithelial cells' viability.

CLINICAL RELEVANCE

The high recurrence rates of denture stomatitis are associated with patient non-adherence to treatments and contaminated prostheses use. Here, we provide the non-patients' cooperation sensible method, which possesses antifungal action, hence improving treatment effectiveness.

Immunometabolism modulation, a new trick of edible and medicinal plants in cancer treatment

The edible and medicinal plants (EMPs) are becoming an abundant source for cancer prevention and treatment since the natural and healthy trend for modern human beings. Currently, there are more than one hundred species of EMPs widely used and listed by the national health commission of China, and most of them indicate immune or metabolic regulation potential in cancer treatment with numerous studies over the past two decades. In the present review, we focused on the metabolic influence in immunocytes and tumor microenvironment, including immune response, immunosuppressive factors and cancer cells, discussing the immunometabolic potential of EMPs in cancer treatment. There are more than five hundred references collected and analyzed through retrieving pharmacological studies deposited in PubMed by medical subject headings and the corresponding names derived from pharmacopoeia of China as a sole criterion. Finally, the immunometabolism modulation of EMPs was sketch out implying an immunometabolic control in cancer treatment.

Beetroot as a functional food with huge health benefits: Antioxidant, antitumor, physical function, and chronic metabolomics activity

Previously, beetroot is mainly consumed as a food additive. In recent years, the beetroot, especially the betalains (betanin) and nitrates it contains, now has received increasing attention for their effective biological activity. Betalains have been proven to eliminate oxidative and nitrative stress by scavenging DPPH, preventing DNA damage, and reducing LDL. It also has been found to exert antitumor activity by inhibiting cell proliferation, angiogenesis, inducing cell apoptosis, and autophagy. In some chronic diseases, nitrate is the main component for lowing blood lipids, glucose, and pressure, while its role in treating hypertension and hyperglycemia has not been clearly stated. Moreover, the intake of nitrate-rich beetroot could enhance athletic performance and attenuate muscle soreness in certain types of exercise. The objective of this review is to provide sufficient evidence for the clarification of health benefits of beetroot, especially in the aspect of biooxidation, neoplastic diseases, some chronic diseases, and energy supplementation.

Bryonia multiflora Extract Induces Autophagy via Regulating Long Non-coding RNAs in Breast Cancer Cells

Bryonia multiflora, one of the species of Bryonia L. (Cucurbitaceae) genus, is a perennial, dioecious, herbaceous plant with rhizome-shaped roots. Bryonia species have anti-inflammatory, antimicrobial, cytotoxic, antioxidant, etc., activities and their components consume antitumoral effects. Purpose of the study to investigate the effect of Bryonia Multiflora extract (BMST) on breast cancer cells. Our results revealed that MCF-7 and MDA-MB-231 cells underwent significant morphological changes leading to cell rounding. No significant changes were observed in the cell viability by MTT. Acridine orange staining of our cells gave rise to think that BMST might lead our cells to autophagy. Therefore, possible molecular mechanisms underlying morphological changes such as autophagy (LC-3B, Beclin, AMBRA1) and apoptosis (Bcl-2) were evaluated on mRNA and protein levels. BMST treated MCF-7 and MDA-MB-231 cells had increased levels of autophagy markers whereas decreased levels of Bcl-2. p21 levels were also found to be increased in both cells. Analysis of lncRNA expressions has shown that BMST treatment led to changes in the expression levels of several lncRNAs playing roles in autophagy. The current study has shown that BMST induces autophagy in MCF-7 and MDA-MB-231 cells via regulating the lncRNAs revealing that BMST could be a promising therapeutic agent.

Beetroot as a Potential Functional Food for Cancer Chemoprevention, a Narrative Review

Patients with cancer are prone to several debilitating side effects including fatigue, insomnia, depression and cognitive disturbances. Beetroot (Beta vulgaris L.) as a health promoting functional food may be potentially beneficial in cancer. As a source of polyphenols, flavonoids, dietary nitrates and other useful nutrients, beetroot supplementation may provide a holistic means to prevent cancer and manage undesired effects associated with chemotherapy. The main aim of this narrative review is to discuss beetroot's nutrient composition, current studies on its potential utility in chemoprevention and cancer-related fatigue or treatment-related side effects such as cardiotoxicity. This review aims to provide the current status of knowledge and to identify the related research gaps in this area. The flavonoids and polyphenolic components present in abundance in beetroot support its significant antioxidant and anti-inflammatory capacities. Most in vitro and in vivo studies have shown promising results; however, the molecular mechanisms underlying chemopreventive and chemoprotective effects of beetroot have not been completely elucidated. Although recent clinical trials have shown that beetroot supplementation improves human performance, translational studies on beetroot and its functional benefits in managing fatigue or other symptoms in patients with cancer are still lacking.

Donkey milk inhibits triple-negative breast tumor progression and is associated with increased cleaved-caspase-3 expression

Donkey milk is considered an ideal substitute for human milk and is considered a potential complementary dairy product for the treatment of a variety of human diseases, including cancer. The purpose of this study was to investigate the inhibitory effect of donkey colostrum (DC) and mature milk (DM) on 4T1 triple-negative breast cancer (TNBC) tumors in mice. Metabolomics analyses showed that a total of 476 possible metabolites were found in both types of milk. Among them, 34 differential metabolites were identified, including 25 up-regulated and 9 down-regulated metabolites in the DC compared with DM. Both DC and DM are rich in many known anticancer constituents. The inhibitory effects of DC and DM on 4T1 primary tumors and the relative organ weight of the liver and lungs were determined by measuring the volume of primary tumors and weighing the liver and lungs. Both DC and DM significantly reduced both the primary tumor size and relative organ weight of the liver and lungs in 4T1 mice without affecting the bodyweight of mice. When the expression of cleaved caspase-3, Bax, and MMP2 was investigated by immunohistochemistry, the results showed that DC and DM inhibited the progression of 4T1 tumors by inducing the expression of cleaved-caspase-3 and Bax, and inhibiting the expression of MMP2 and CD31. Our data suggest that DC and DM inhibit the growth and metastasis of mouse 4T1 tumors by inducing apoptosis.
