Abstract
Nicotine pouches contain fewer characteristic toxicants than conventional tobacco products. However, the associated risks in terms of toxicity and addiction potential are still unclear. Therefore, endpoints of toxicity and contents of flavoring substances were investigated in this study. The in vitro toxicity of five different nicotine pouches and the reference snus CRP1.1 were studied in human gingival fibroblasts (HGF-1). Cells were exposed to product extracts (nicotine contents: 0.03-1.34 mg/mL) and sampled at different time points. Cytotoxicity, total cellular reactive oxygen species (ROS) levels, and changes in the expression levels of inflammatory and oxidative stress genes were assessed. Flavor compounds used in the nicotine pouches were identified by GC-MS. Cytotoxicity was observed in two nicotine pouches. Gene expression of interleukin 6 (IL6) and heme oxygenase 1 (HMOX1) was upregulated by one and three pouches, respectively. ROS production was either increased or decreased, by one pouch each. CRP1.1 caused an upregulation of IL6 and elevated ROS production. Toxicity was not directly dependent on nicotine concentration and osmolarity. A total of 56 flavorings were detected in the five nicotine pouches. Seven flavorings were classified according to the harmonized hazard classification system as laid down in the European Classification, Labelling and Packaging regulation. Nine flavorings are known cytotoxins. Cytotoxicity, inflammation, and oxidative stress responses indicate that adverse effects such as local lesions in the buccal mucosa may occur after chronic product use. In conclusion, flavorings used in nicotine pouches likely contribute to the toxicity of nicotine pouches.

Abstract
Chili peppers pungent and spicy flavor is caused by capsaicin, which is one of their active components. As well as being an important aspect of fruit quality, the hot sensation is a key attribute linked to members of the Capsicum genus. Extraction is one of the most popular techniques for separating and purifying organic materials, but the technique must be quick, affordable, adaptable, efficient, and high performing. This review formulates the extraction of Capsaicin from chili peppers. The extraction methods used were solvent extraction (SE), ultrasound assisted extraction (UAE), microwave assisted extraction (MAE), enzymatic treatment, supercritical fluid extraction (SFE), solid phase microextraction (SPME), aqueous two phase system (ATPS) and liquid under pressure (PLE). The content of capsaicin in the extract was evaluated by using Thin Layer Chromatography (TLC), Fourier Transform Infrared Spectroscopy (FTIR) and High performance Liquid Chromatography (HPLC). The insecticidal activity of capsaicin in storage insects in food grains for shelf life enhancement and bio availability of capsaicinoids in terms of absorption, distribution, metabolism, and elimination were also discussed.

Abstract
Capsaicin is the main food active component in Capsicum that has gained considerable attention due to its broad biological activities, including antioxidation, anti-inflammation, anti-tumor, weight regulation, cardiac protection, anti-calculi, and diurnal-circadian regulation. The potent biological effects of capsaicin are intimately related to metabolic pathways such as lipid metabolism, energy metabolism, and antioxidant stress. Mass spectrometry (MS) has emerged as an effective tool for deciphering the mechanisms underlying capsaicin metabolism and its biological impacts. However, it remains challenging to accurately identify and quantify capsaicin and its self-metabolites in complex food and biological samples, and to integrate multi-omics data generated from MS. In this work, we summarized recent advances in the detection of capsaicin and its self-metabolites using MS and discussed the relevant MS-based studies of metabolic pathways. Furthermore, we discussed current issues and future directions in this field. In-depth studies of capsaicin metabolism and its physiological functions based on MS is anticipated to yield new insights and methods for preventing and treating a wide range of diseases.

Abstract
Capsaicin widely exists in the Capsicum genus (e.g., hot peppers) and is commonly used as a food additive or medicinal material. In this work, microbial transformation of capsaicin was performed based on the three cultivated human intestinal fungi. Fourteen metabolites were obtained, and their chemical structures were elucidated by spectroscopic data analysis, including 13 compounds with undescribed structures. Hydroxylation, lactylation, succinylation, citric acylation, and acetylation were observed for these microbial metabolites derived from capsaicin, which indicated diverse catalytic characteristics of human intestinal fungi. In an in vitro bioassay, four metabolites and capsaicin inhibited the activity of lysine-specific demethylase 1 (LSD1) with a more than 70% inhibitory rate at 10 μM. In particular, 9,5'-dihydroxycapsaicin displayed the strongest inhibitory effect with an IC50 of 1.52 μM. Therefore, capsaicin analogs displayed potential application as LSD1 inhibitors against the invasion and migration of cancer cells.

Lactobacillus rhamnosus attenuates Thai chili extracts induced gut inflammation and dysbiosis despite capsaicin bactericidal effect against the probiotics, a possible toxicity of high dose capsaicin. PLoS One 2021; 16:e0261189. [PMID: 34941893 PMCID: PMC8699716 DOI: 10.1371/journal.pone.0261189] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 11/24/2021] [Indexed: 12/23/2022] Open
Abstract
Because of a possible impact of capsaicin in the high concentrations on enterocyte injury (cytotoxicity) and bactericidal activity on probiotics, Lactobacillus rhamnosus L34 (L34) and Lactobacillus rhamnosus GG (LGG), the probiotics derived from Thai and Caucasian population, respectively, were tested in the chili-extract administered C57BL/6 mice and in vitro experiments. In comparison with placebo, 2 weeks administration of the extract from Thai chili in mice caused loose feces and induced intestinal permeability defect as indicated by FITC-dextran assay and the reduction in tight junction molecules (occludin and zona occludens-1) using fluorescent staining and gene expression by quantitative real-time polymerase chain reaction (qRT-PCR). Additionally, the chili extracts also induced the translocation of gut pathogen molecules; lipopolysaccharide (LPS) and (1→3)-β-d-glucan (BG) and fecal dysbiosis (microbiome analysis), including reduced Firmicutes, increased Bacteroides, and enhanced total Gram-negative bacteria in feces. Both L34 and LGG attenuated gut barrier defect (FITC-dextran, the fluorescent staining and gene expression of tight junction molecules) but not improved fecal consistency. Additionally, high concentrations of capsaicin (0.02-2 mM) damage enterocytes (Caco-2 and HT-29) as indicated by cell viability test, supernatant cytokine (IL-8), transepithelial electrical resistance (TEER) and transepithelial FITC-dextran (4.4 kDa) but were attenuated by Lactobacillus condition media (LCM) from both probiotic-strains. The 24 h incubation with 2 mM capsaicin (but not the lower concentrations) reduced the abundance of LGG (but not L34) implying a higher capsaicin tolerance of L34. However, Lactobacillus rhamnosus fecal abundance, using qRT-PCR, of L34 or LGG after 3, 7, and 20 days of the administration in the Thai healthy volunteers demonstrated the similarity between both strains. In conclusion, high dose chili extracts impaired gut permeability and induced gut dysbiosis but were attenuated by probiotics. Despite a better capsaicin tolerance of L34 compared with LGG in vitro, L34 abundance in feces was not different to LGG in the healthy volunteers. More studies on probiotics with a higher intake of chili in human are interesting.

Abstract
Capsaicin, primarily known as the pungent ingredient in hot peppers, is rapidly metabolized in the human body by enzymatic processes altering the pharmacological as well as toxicological properties. Herein, the oxidative transformation of capsaicin was investigated in vitro with electrochemistry as well as human liver microsomal incubations. The reaction mixtures were analyzed with liquid chromatography-mass spectrometry. Structure elucidation involved accurate mass measurements and multistage tandem mass spectrometry experiments. In total, 126 transformation products were detected. Electrochemistry provided evidence for 101 transformation products and the microsomal incubations for 46 species. 21 compounds were observed with both approaches. Identified oxidative pathways likely occurring during the phase I metabolism included dehydrogenation, O-demethylation, and hydroxylation reactions as well as combinations thereof. Furthermore, trapping of reactive intermediates either with glutathione or with electrochemically activated ribonucleosides provided evidence for the possible production of phase II metabolites and covalent adducts with a genetic material. Evidence for the occurrence of some capsaicin metabolites in humans was obtained by urine screening.

Abstract
Stress granules (SGs) are cytoplasmic biomolecular condensates that are formed against a variety of stress conditions when translation initiation is perturbed. SGs form through the weak protein-protein, protein-RNA, and RNA-RNA interactions, as well as through the intrinsically disordered domains and post-translation modifications within RNA binding proteins (RBPs). SGs are known to contribute to cell survivability by minimizing the stress-induced damage to the cells by delaying the activation of apoptosis. Here, we find that dihydrocapsaicin (DHC), an analogue of capsaicin, is a SG inducer that promotes polysome disassembly and reduces global protein translation via phosphorylation of eIF2α. DHC-mediated SG assembly is controlled by the phosphorylation of eIF2α at serine 51 position and is controlled by all four eIF2α stress kinases (i.e., HRI, PKR, PERK, and GCN2) with HRI showing maximal effect. We demonstrate that DHC is a bonafide compound that induces SG assembly, disassembles polysome, phosphorylates eIF2α in an HRI dependent manner, and thereby arrest global translation. Together, our results suggest that DHC is a novel SG inducer and an alternate to sodium arsenite to study SG dynamics.

Abstract
Cardiopulmonary functions such as respiratory depression, severe irritation, inflamed respiratory tract, hyperventilation and, tachycardia are the most affected ones when it comes to the riot control agent oleoresin capsicum (OC) exposure. However, no studies have been done to elucidate the mechanism underlying deterioration of the combined cardiopulmonary functions. Parameters such as acute respiratory, cardiac, parameters and ultrasonography (USG) measurements were investigated in an in vivo setup using Wistar rats at 1 h and 24 h post inhalation exposure to 2%, 6% and 10% OC, whereas, cell migration in rat peritoneal mast cells (RPMCs), metabolomics and eosinophil peroxidase (EPO) activity in bronchoalveolar lavage fluid (BALF) were investigated in an in vitro setup. Results obtained from electrophysiological recording indicated that OC exposure produces apnea and decrease in mean arterial pressure (MAP) was obtained from hemodynamic parameters whereas cardiac parameters assessment revealed increase in the level of cardiac output (CO) and decrease in stroke volume (SV) with recovery towards the post-exposure period. A decrease in the percentage area of certain fatty acid pathway metabolites in BALF appropriately linked the lung injury following OC exposure which was further cemented by increasing concentration of EPO. Histopathology and SEM also proved to be favorable techniques for the detection of OC induced physiological cardiac and pulmonary modifications respectively. Furthermore, Boyden chamber experiment established the chemoattractant property of OC. It may be concluded from the above studies that these newly reported facets may be utilized pharmacologically to mitigate cardiopulmonary adverse effects owing to OC exposure.

Abstract
Aim: The use of oleoresin capsicum (OC) sprays, due to their irreversible health effects has now grown into a matter of heated debate. In the present study, the early phase pulmonary events involving chemotactic and inflammatory mediators after short-exposure duration to OC have been presented.Materials and methods: Female Wistar rats used in the evaluation of respiratory parameters at 1 h, 3 h, and 24 h post-exposure, were sacrificed for the evaluation of blood cell counts, BALF cytokine estimation, lung capillary leakage, study of oxidative stress and histopathology of the lungs.Results: Results confirmed a dose-dependent effect of OC exposure on serum clinical chemistry and hematological parameters. Subsequent upregulation of IL-l and TNF-α indicated lung's responses to acute oxidant-induced injury and inflammation after OC exposure. Significant alterations in the pulmonary levels of reactive oxygen intermediates were seen following the inhalation of OC. Infiltration of polymorphonuclear leukocytes, mostly neutrophils, into the site of infection was evident in the cytocentrifuged samples of BALF. Histological samples of rat lung sections revealed the recruitment of inflammatory cells in the airways and around blood vessels in the subepithelium of conducting airways.Conclusion: Results of the present study demonstrated that, exposure to OC spray may mitigate inflammatory response and development of acute lung injury in rats. However, it can be concluded that although OC spray causes pulmonary hazards in the aforementioned concentrations, it can be used as a non-lethal riot control agent in minimal concentration. Understanding the in-depth mechanism of action in the molecular and receptor level will help in developing effective antagonist against OC.

Abstract
Capsaicin (CAP) is a principal pungent ingredient in hot peppers, it is also employed as a common food additive, an efficient pharmaceutical component, or even a riot control agent. CAP exerts various pharmacological activities as well as associated adverse physiological responses and causes moderate toxicity if overused. A full screening and identification of CAP metabolites in combination with its main detoxification pathways are crucial for the clear demonstration on its pharmacological and toxicological significance. Here, we employed a post-acquisition data-mining metabolic screening approach to rapidly find and identify a broad range of CAP metabolites generated from in vitro human liver microsomes, based on an ultra-performance liquid chromatography-quadrupole orbitrap high resolution tandem mass spectrometric method. First, we collected full scan MS and MS/MS data sets by a data-dependent acquisition method in positive ion mode, and then we employed a modified mass defect filter and a diagnostic ion filter to screen and identify all the probable CAP metabolites, combining with information including retention time, accurate mass, characteristic fragments, and relevant drug biotransformation patterns. In comparison with the stable isotope-labeled CAP involved biotransformation products, we confirmed 19 functionalized metabolites and 13 glutathione (GSH) conjugates of CAP, in which 13 metabolites are reported for the first time. We then briefly depicted an overview metabolic pathway of CAP from the GSH detoxification viewpoint, revealed that various metabolites of CAP can be generated from single or multiple biotransformation and metabolic reactions. Both CAP and its reactive metabolites produced relevant GSH conjugates, which indicates a wide and important detoxification value of GSH conjugation way.

[PMID: 31724206 DOI: 10.1111/jfbc.13099] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 10/08/2019] [Accepted: 10/28/2019] [Indexed: 12/20/2022]
Abstract
Chili is a spicy plant and is widely used in traditional medicine. Capsaicin and dihydrocapsaicin belong to the capsaicinoid group, which is produced from chili. This study aims to investigate the antidiabetic properties and anti-melanin synthesis of capsaicinoids by studying the inhibitory activity of capsaicin and dihydrocapsaicin with α-glucosidase, α-amylase, and tyrosinase. The results revealed that dihydrocapsaicin with IC50 had 4.13-fold and 3.00-fold for α-glucosidase and α-amylase, respectively, which are lower than capsaicin. Moreover, the IC50 of capsaicin with tyrosinase had 1.73 times less than dihydrocapsaicin. The inhibition constant (Ki ) also supported that the dihydrocapsaicin had higher inhibitory activity than capsaicin against α-glucosidase and α-amylase, but lower inhibitory activity than capsaicin on tyrosinase. Capsaicin and dihydrocapsaicin functioned in mixed-type inhibition on each enzyme, except that capsaicin functioned in competitive inhibition of tyrosinase. The results indicated that capsaicin and dihydrocapsaicin had more potent anti-melanin synthesis than antidiabetic properties. PRACTICAL APPLICATIONS: This study presents the inhibition potential of capsaicin and dihydrocapsaicin on antidiabetes and anti-melanin properties by standard methods for inhibitory activity against α-glucosidase, α-amylase, and tyrosinase. We suggest the application of these results in the development of antidiabetes and anti-melanin drugs for pharmaceutical and cosmetic industries.

Abstract
Cytotoxic chemotherapy is the mainstay of cancer treatment. Conventional chemotherapeutic agents do not distinguish between normal and neoplastic cells. This leads to severe toxic side effects, which may necessitate the discontinuation of treatment in some patients. Recent research has identified key molecular events in the initiation and progression of cancer, promoting the design of targeted therapies to selectively kill tumor cells while sparing normal cells. Although, the side effects of such drugs are typically milder than conventional chemotherapies, some off-target effects still occur. Another serious challenge with all chemotherapies is the acquisition of chemoresistance upon prolonged exposure to the drug. Therefore, identifying supplementary agents that sensitize tumor cells to chemotherapy-induced apoptosis and help minimize drug resistance would be valuable for improving patient tolerance and response to chemotherapy. The use of effective supplementary agents provides a twofold advantage in combination with standard chemotherapy. First, by augmenting the activity of the chemotherapeutic drug it can lower the dose needed to kill tumor cells and decrease the incidence and severity of treatment-limiting side effects. Second, adjuvant therapies that lower the effective dose of chemotherapy may delay/prevent the development of chemoresistance in tumors. Capsaicinoids, a major class of phytochemical compounds isolated from chili peppers, have been shown to improve the efficacy of several anti-cancer drugs in cell culture and animal models. The present chapter summarizes the current knowledge about the chemosensitizing activity of capsaicinoids with conventional and targeted chemotherapeutic drugs, highlighting the potential use of capsaicinoids in novel combination therapies to improve the therapeutic indices of conventional and targeted chemotherapeutic drugs in human cancers.

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2019; 156:145-151. [PMID: 31027574 DOI: 10.1016/j.pestbp.2019.02.015] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/16/2018] [Revised: 02/18/2019] [Accepted: 02/24/2019] [Indexed: 06/09/2023]
Abstract
Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is the most abundant capsaicinoids found in hot peppers (Capsicum annum and Capsicum frutescens). It has been well documented that capsaicin plays an important role in the defense against the attack of herbivores or pathogens on Capsicum plants. A few insect herbivores such as Helicoverpa armigera and Helicoverpa assulta have been recorded to be capable of feeding on hot pepper fruits, suggesting that these insects evolve mechanisms against the toxicity of capsaicin. Although cytochrome P450-meidated detoxification is considered to be an important mechanism by which cotton bollworms cope with capsaicin, experimental evidence is lacking. In this study, we compared the capacity of four H. armigera P450s (CYP6B6, CYP9A12, CYP9A14 and CYP9A17) in capsaicin metabolism, and the capsaicin metabolites were screened and tentatively identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). HPLC analyses showed that depletion rates of capsaicin were 21.9 ± 0.1, 11.9 ± 1.5, 16.3 ± 1.4 and 14.8 ± 0.2 min-1 for CYP6B6, CYP9A12, CYP9A14 and CYP9A17 respectively. The transformation of capsaicin was inhibited by the P450 inhibitor piperonyl butoxide. A total of seven products were detected, and hydroxylation (aromatic and aliphatic) and dehydrogenation were found to be two main pathways in capsaicin metabolism. In addition, capsaicin metabolism was enzyme selective: M1 (ω-hydroxylated N-macrocyclic metabolite) and M3 (ω-hydroxylated metabolite) were uniquely detected in the CYP6B6 catalytic reaction, while M4 (ω-n hydroxylated capsaicin), M5 (diene of capsaicin) and M6 (doubly oxidized metabolite of dehydrogenated capsaicin) were only detectable in CYP9A metabolisms. A capsaicin dimer (5, 5'-dicapsaicin) was found to be the major metabolite of CYP9A reactions, but the minor product produced by CYP6B6. An overall more similar behavior in capsaicin metabolism was observed among CYP9As than between CYP6B6 and CYP9As. Our data demonstrate that CYP6B6 and CYP9As have a potent capability to transform capsaicin, and individual P450 produce unique metabolite profile. These findings help us to understand the molecular basis of capsaicin adaptation in H. armigera.

Abstract
Two compounds termed 1 and 2 were isolated from the leaves of Capsicum chinense using column chromatography. Their structures were identified as amide scaffolds by analyzing spectroscopic signals. Compounds 1 and 2 have been confirmed to be competitive soluble epoxide hydrolase (sEH) inhibitors that suppress the catalytic reaction of sEH in a dose-dependent manner in vitro. Molecular docking was used for analyzing two binding clusters of ligand and receptor. The results confirmed that the key amino acids interacting with the ligand were Asp335, Tyr383, and Gln384. On the basis of molecular dynamics, inhibitors 1 and 2 were noted to interact at a distance of 3.5 Å from Asp335, Tyr383, Leu408 and Tyr466, and Asp335, Tyr383, and Tyr466, respectively. These results highlight the potential of N-trans-coumaroyltyramine (1) and N-trans-feruloyltyramine (2) as sEH inhibitors.

Abstract
Capsaicinoids are reported to have a bunch of promising pharmacological activities, among them antibacterial effects against various strains of bacteria. In this study the effect on efflux pumps of mycobacteria was investigated. The importance of efflux pumps, and the inhibition of these, is rising due to their involvement in antibiotic resistance development. In order to draw structure and activity relationships we tested natural and synthetical capsaicinoids as well as synthetical capsinoids. In an accumulation assay these compounds were evaluated for their ability to accumulate ethidium bromide into mycobacterial cells, a well-known substrate for efflux pumps. Capsaicin and dihydrocapsaicin, the two most abundant capsaicinoids in Capsicum species, proved to be superior efflux pump inhibitors compared to the standard verapamil. A dilution series showed dose dependency of both compounds. The compound class of less pungent capsinoids qualified for further investigation as antibacterials against Mycobacterium smegmatis.

Abstract
The nutritional compound capsaicin is the major spicy ingredient of chili peppers. Although traditionally associated with analgesic activity, recent studies have shown that capsaicin has profound antineoplastic effects in several types of human cancers. However, the applications of capsaicin as a clinically viable drug are limited by its unpleasant side effects, such as gastric irritation, stomach cramps, and burning sensation. This has led to extensive research focused on the identification and rational design of second-generation capsaicin analogs, which possess greater bioactivity than capsaicin. A majority of these natural capsaicinoids and synthetic capsaicin analogs have been studied for their pain-relieving activity. Only a few of these capsaicin analogs have been investigated for their anticancer activity in cell culture and animal models. The present review summarizes the current knowledge of the growth-inhibitory activity of natural capsaicinoids and synthetic capsaicin analogs. Future studies that examine the anticancer activity of a greater number of capsaicin analogs represent novel strategies in the treatment of human cancers.

Abstract
A significant number of experimental and clinical studies published in peer-reviewed journals have demonstrated promising pharmacological properties of capsaicin in relieving signs and symptoms of non-communicable diseases (chronic diseases). This chapter provides an overview made from basic and clinical research studies of the potential therapeutic effects of capsaicin, loaded in different application forms, such as solution and cream, on chronic diseases (e.g. arthritis, chronic pain, functional gastrointestinal disorders and cancer). In addition to the anti-inflammatory and analgesic properties of capsaicin largely recognized via, mainly, interaction with the TRPV1, the effects of capsaicin on different cell signalling pathways will be further discussed here. The analgesic, anti-inflammatory or apoptotic effects of capsaicin show promising results in arthritis, neuropathic pain, gastrointestinal disorders or cancer, since evidence demonstrates that the oral or local application of capsaicin reduce inflammation and pain in rheumatoid arthritis, promotes gastric protection against ulcer and induces apoptosis of the tumour cells. Sadly, these results have been paralleled by conflicting studies, which indicate that high concentrations of capsaicin are likely to evoke deleterious effects, thus suggesting that capsaicin activates different pathways at different concentrations in both human and rodent tissues. Thus, to establish effective capsaicin doses for chronic conditions, which can be benefited from capsaicin therapeutic effects, is a real challenge that must be pursued.
