Anti-Inflammatory, Cytotoxic, and Genotoxic Effects of Soybean Oligopeptides Conjugated with Mannose. Foods 2024; 13:2558. [PMID: 39200485 PMCID: PMC11353420 DOI: 10.3390/foods13162558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 08/12/2024] [Accepted: 08/14/2024] [Indexed: 09/02/2024] Open
Abstract
Soy protein is considered to be a high-quality protein with a range of important biological functions. However, the applications of soy protein are limited due to its poor solubility and high level of allergenicity. Its peptides have been of interest because they exert the same biological functions as soy protein, but are easier to absorb, more stable and soluble, and have a lower allergenicity. Moreover, recent research found that an attachment of chemical moieties to peptides could improve their properties including their biodistribution, pharmacokinetic, and biological activities with lower toxicity. This study therefore aimed to acquire scientific evidence to support the further application and safe use of the soybean oligopeptide (OT) conjugated with allulose (OT-AL) or D-mannose (OT-Man). The anti-inflammation, cytotoxicity, and genotoxicity of OT, OT-AL, and OT-Man were investigated. The results showed that OT, AL, Man, OT-AL, and OT-Man at doses of up to 1000 µg/mL were not toxic to HepG2 (liver cancer cells), HEK293 (kidney cells), LX-2 (hepatic stellate cells), and pre- and mature-3T3-L1 (fibroblasts and adipocytes, respectively), while slightly delaying the proliferation of RAW 264.7 cells (macrophages) at high doses. In addition, the oligopeptides at up to 800 µg/mL were not toxic to isolated human peripheral blood mononuclear cells (PBMCs) and did not induce hemolysis in human red blood cells (RBCs). OT-Man (200 and 400 µg/mL), but not OT, AL, Man, and OT-AL, significantly reduced the production of NO and the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX2) stimulated by lipopolysaccharide (LPS) in RAW 264.7 cells, suggesting that the mannose conjugation of soy peptide had an inhibitory effect against LPS-stimulated inflammation. In addition, the secretion of interleukin-6 (IL-6) stimulated by LPS was significantly reduced by OT-AL (200 and 400 µg/mL) and OT-Man (400 µg/mL). The tumor necrosis factor-α (TNF-α) level was significantly decreased by OT (400 µg/mL), AL (400 µg/mL), OT-AL (200 µg/mL), and OT-Man (200 and 400 µg/mL) in the LPS-stimulated cells. The conjugation of the peptides with either AL or Man is likely to be enhance the anti-inflammation ability to inhibit the secretion of cytokines. As OT-Man exhibited a high potential to inhibit LPS-induced inflammation in macrophages, its mutagenicity ability was then assessed in bacteria and Drosophila. These findings showed that OT-Man did not trigger DNA mutations and was genome-safe. This study provides possible insights into the health advantages and safe use of conjugated soybean peptides.

Abstract
Biochemical analysis of human normal bronchial cells (BEpiC) and human cancer lung cells (A549) has been performed by using Raman spectroscopy and Raman imaging. Our approach provides a biochemical compositional mapping of the main cell components: nucleus, mitochondria, lipid droplets, endoplasmic reticulum, cytoplasm and cell membrane. We proved that Raman spectroscopy and Raman imaging can distinguish successfully BEpiC and A549 cells. In this study, we have focused on the role of mannose in cancer development. It has been shown that changes in the concentration of mannose can regulate some metabolic processes in cells. Presented results suggest lipids and proteins can be considered as Raman biomarkers during lung cancer progression. Analysis obtained for bands 1444 cm-1, and 2854 cm-1 characteristic for lipids and derivatives proved that the addition of mannose reduced levels of these compounds. Results obtained for protein compounds based on bands 858 cm-1, 1004 cm-1 and 1584 cm-1 proved that the addition of mannose increases the values of protein in BEpiC cells and blocks protein glycolisation in A549 cells. Noticing Raman spectral changes in BEpiC and A549 cells supplemented with mannose can help to understand the mechanism of sugar metabolism during cancer development and could play in the future an important role in clinical treatment.

Abstract
The nature of alpha-D-mannose-natural aldohexose sugar, C-2 glucose epimer, whose intended use is for preventing urinary tract infections-in the interaction with E. coli is addressed in order to drive the issue of its regulatory classification as a medicinal product or medical device. PRISMA systematic review approach was applied; Delphi Panel method was used to target consensus on statements retrieved from evidence. Based on regulatory definitions and research evidence, the mechanism of D-mannose does not involve a metabolic or immunological action while there is uncertainty regarding the pharmacological action. Specific interaction between the product and the bacteria within the body occurs, but its nature is inert: it does not induce a direct response activating or inhibiting body processes. Moreover, the action of D-mannose takes place, even if inside the bladder, outside the epithelium on bacteria that have not yet invaded the urothelial tissue. Therefore, its mechanism of action is not directed to host structures but to structures (bacteria) external to the host's tissues. On the basis of current regulation, the uncertainty as regard a pharmacological action of alpha-D-mannose makes possible its medical device classification: new regulations and legal judgments can add further considerations. From a pharmacological perspective, research is driven versus synthetic mannosides: no further considerations are expected on alpha-D-mannose.

Abstract
Urinary tract infections (UTIs) are among the most common bacterial infections seen in clinical practice. The ascent of UTI-causing pathogens to the kidneys results in pyelonephritis, which can trigger kidney injury, scarring and ultimately impair kidney function. Despite sizable efforts to understand how infections develop or are cleared in the bladder, our appreciation of the mechanisms by which infections develop, progress or are eradicated in the kidney is limited. The identification of virulence factors that are produced by uropathogenic Escherichia coli to promote pyelonephritis have begun to fill this knowledge gap, as have insights into the mechanisms by which kidney tubular epithelial cells oppose uropathogenic E. coli infection to prevent or eradicate UTIs. Emerging data also illustrate how specific cellular immune responses eradicate infection whereas other immune cell populations promote kidney injury. Insights into the mechanisms by which uropathogenic E. coli circumvent host immune defences or antibiotic therapy to cause pyelonephritis is paramount to the development of new prevention and treatment strategies to mitigate pyelonephritis and its associated complications.

Young Women's Attitudes and Behaviors in Treatment and Prevention of UTIs: Are Biomedical Students at an Advantage? Antibiotics (Basel) 2023; 12:1107.

Abstract
We wanted to investigate whether students who study within biomedical fields (i.e., medicine, pharmacy science) differ from those whose studies are not connected to the biomedical field in terms of their attitudes and behaviors related to urinary tract infections (UTIs). This was a cross-sectional survey-based study conducted among 392 female students, of whom 243 attended a biomedical school and 149 (38.0%) attended a non-biomedical school, using a previously published tool. The survey was distributed as an online link via student representatives at different faculties. Only 22 (5.6%) of women felt that they could not recognize a UTI. A greater proportion of biomedical students wiped front to back, while significantly more non-biomedical students chose cotton underwear and avoided daily sanitary pads compared to biomedical students. As many as 215 (54.8%) women stated that they used cranberry preparations. Biomedical students showed greater awareness about possible resistance to repeated treatment (p = 0.002) and greater knowledge of possible interactions of antibiotics (p < 0.001). This study reveals that young women are confident in recognizing an UTIs, are open to alternative treatments, and would consider UTI management in a pharmacy setting. However, it reveals that there might be gaps in their knowledge regarding antibiotic resistance risks, possible interactions, and efficacy of available preparations, as participants from the group of biomedical students showed greater knowledge and different behaviors.

D-Mannose Plus Saccharomyces boulardii to Prevent Urinary Tract Infections and Discomfort after Cystoscopy: A Single-Center Prospective Randomized Pilot Study. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1165. [PMID: 37374369 DOI: 10.3390/medicina59061165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 06/14/2023] [Accepted: 06/15/2023] [Indexed: 06/29/2023]
Abstract
Background and Objectives: Patients undergoing cystoscopy can experience discomfort or pain during the procedure. In some cases, a urinary tract infection (UTI) with storage lower urinary tract symptoms (LUTS) may occur in the days following the procedure. This study aimed to assess the efficacy of D-mannose plus Saccharomyces boulardii in the prevention of UTIs and discomfort in patients undergoing cystoscopy. Materials and Methods: A single-center prospective randomized pilot study was conducted between April 2019 and June 2020. Patients undergoing cystoscopy for suspected bladder cancer (BCa) or in the follow-up for BCa were enrolled. Patients were randomized into two groups: D-Mannose plus Saccharomyces boulardii (Group A) vs. no treatment (Group B). A urine culture was prescribed regardless of symptoms 7 days before and 7 days after cystoscopy. The International Prostatic Symptoms Score (IPSS), 0-10 numeric rating scale (NRS) for local pain/discomfort, and EORTC Core Quality of Life questionnaire (EORTC QLQ-C30) were administered before cystoscopy and 7 days after. Results: A total of 32 patients (16 per group) were enrolled. No urine culture was positive in Group A 7 days after cystoscopy, while 3 patients (18.8%) in Group B had a positive control urine culture (p = 0.044). All patients with positive control urine culture reported the onset or worsening of urinary symptoms, excluding the diagnosis of asymptomatic bacteriuria. At 7 days after cystoscopy, the median IPSS of Group A was significantly lower than that of Group B (10.5 vs. 16.5 points; p = 0.021), and at 7 days, the median NRS for local discomfort/pain of Group A was significantly lower than that for Group B (1.5 vs. 4.0 points; p = 0.012). No statistically significant difference (p > 0.05) in the median IPSS-QoL and EORTC QLQ-C30 was found between groups. Conclusions: D-Mannose plus Saccharomyces boulardii administered after cystoscopy seem to significantly reduce the incidence of UTI, the severity of LUTS, and the intensity of local discomfort.

Abstract
PURPOSE OF REVIEW There is a growing interest in nonantibiotic prevention strategies for recurrent urinary tract infections (rUTIs). Our objective is to provide a focused, pragmatic review of the latest evidence. RECENT FINDINGS Vaginal estrogen is well tolerated and effective for preventing rUTI in postmenopausal women. Cranberry supplements at sufficient doses are effective in preventing uncomplicated rUTI. Methenamine, d -mannose, and increased hydration all have evidence to support their use, although the evidence is of somewhat variable quality. SUMMARY There is sufficient evidence to recommend vaginal estrogen and cranberry as first-line rUTI prevention strategies, particularly in postmenopausal women. Prevention strategies can be used in series or in tandem, based on patient preference and tolerance for side effects, to create effective nonantibiotic rUTI prevention strategies.

Abstract
Selective antiadhesion antagonists of Uropathogenic Escherichia coli (UPEC) type-1 Fimbrial adhesin (FimH) are attractive alternatives for antibiotic therapies and prophylaxes against acute or recurrent urinary tract infections (UTIs) caused by UPECs. A rational small library of FimH antagonists based on previously described C-linked allyl α-D-mannopyranoside was synthesized using Heck cross-coupling reaction using a series of iodoaryl derivatives. This work reports two new members of FimH antagonist amongst the above family with sub nanomolar affinity. The resulting hydrophobic aglycones, including constrained alkene and aryl groups, were designed to provide additional favorable binding interactions with the so-called FimH "tyrosine gate". The newly synthesized C-linked glycomimetic antagonists, having a hydrolytically stable anomeric linkage, exhibited improved binding when compared to previously published analogs, as demonstrated by affinity measurement through interactions by FimH lectin. The crystal structure of FimH co-crystallized with one of the nanomolar antagonists revealed the binding mode of this inhibitor into the active site of the tyrosine gate. In addition, selected mannopyranoside constructs neither affected bacterial growth or cell viability nor interfered with antibiotic activity. C-linked mannoside antagonists were effective in decreasing bacterial adhesion to human bladder epithelial cells (HTB-9). Therefore, these molecules constituted additional therapeutic candidates' worth further development in the search for potent anti-adhesive drugs against infections caused by UPEC.

Abstract
BACKGROUND Astronauts undergo significant microgravity-induced bone loss during space missions, which has become one of the three major medical problems hindering human's long-term space flight. A risk-free and antiresorptive drug is urgently needed to prevent bone loss during space missions. D-mannose is a natural C-2 epimer of D-glucose and is abundant in cranberries. This study aimed to investigate the protective effects and potential mechanisms of D-mannose against bone loss under weightlessness. METHODS The hind legs of tail-suspended (TS) rats were used to mimic weightlessness on Earth. Rats were administered D-mannose intragastrically. The osteoclastogenic and osteogenic capacity of D-mannose in vitro and in vivo was analyzed by micro-computed tomography, biomechanical assessment, bone histology, serum markers of bone metabolism, cell proliferation assay, quantitative polymerase chain reaction, and western blotting. RNA-seq transcriptomic analysis was performed to detect the underlying mechanisms of D-mannose in bone protection. RESULTS The TS rats showed lower bone mineral density (BMD) and poorer bone morphological indices. D-mannose could improve BMD in TS rats. D-mannose inhibited osteoclast proliferation and fusion in vitro, without apparent effects on osteoblasts. RNA-seq transcriptomic analysis showed that D-mannose administration significantly inhibited the cell fusion molecule dendritic cell-specific transmembrane protein (DC-STAMP) and two indispensable transcription factors for osteoclast fusion (c-Fos and nuclear factor of activated T cells 1 [NFATc1]). Finally, TS rats tended to experience dysuria-related urinary tract infections (UTIs), which were suppressed by treatment with D-mannose. CONCLUSION D-mannose protected against bone loss and UTIs in rats under weightlessness. The bone protective effects of D-mannose were mediated by inhibiting osteoclast cell fusion. Our findings provide a potential strategy to protect against bone loss and UTIs during space missions.

Abstract
The rise in antimicrobial resistance (AMR) has complicated the management of urinary tract infections (UTIs). The objective of this study was to evaluate the antimicrobial susceptibility patterns of Escherichia coli and Klebsiella pneumoniae. Design: prospective observational study. Bacteria were classified as susceptible or resistant to ampicillin-sulbactam, amikacin, gentamicin, ciprofloxacin, norfloxacin, nitrofurantoin, trimethoprim-sulfamethoxazole (TMP/SMZ), ertapenem, meropenem, and fosfomycin. The sensitivity to fosfomycin and chloramphenicol was evaluated by the disk diffusion method. Statistical analysis: the chi-square test and Fisher’s exact test were used to compare differences between categories. A p value < 0.05 was considered statistically significant. Isolates were collected from January 2019 to November 2020 from 21 hospitals and laboratories. A total of 238 isolates were received: a total of 156 E. coli isolates and 82 K. pneumoniae isolates. The majority were community-acquired infections (64.1%). Resistance was >20% for beta-lactams, aminoglycosides, fluoroquinolones, and TMP/SMZ. For E. coli isolates, resistance was <20% for amikacin, fosfomycin, and nitrofurantoin; for K. pneumoniae, amikacin, fosfomycin, chloramphenicol, and norfloxacin. All were susceptible to carbapenems. K. pneumoniae isolates registered a higher proportion of extensively drug-resistant bacteria in comparison with E. coli (p = 0.0004). In total, multidrug-resistant bacteria represented 61% of all isolates. Isolates demonstrated high resistance to beta-lactams, fluoro-quinolones, and TMP/SMZ.

Systematic review of the effect of D‑mannose with or without other drugs in the treatment of symptoms of urinary tract infections/cystitis (Review). Biomed Rep 2022; 17:69.

Abstract
Several studies, reviews and meta-analyses have documented that D-mannose use lowers the risk of recurrent urinary tract infections (UTI), but its role in the treatment of UTI/cystitis-related symptoms is unclear. In particular, no systematic review has analyzed the role of treatment with D-mannose in acute UTI/cystitis. In this paper, we systematically reviewed the published data on the effect of D-mannose, alone or in association with other compounds, on the typical symptoms of UTI/cystitis. PubMed/Medline and EMBASE databases were searched, from 1990 to January 2022, using combinations of the following keywords: ‘urinary tract infections’, ‘cystalgia’, ‘recurrent next urinary tract infection’, ‘cystitis’, ‘mannose’, ‘mannoside’, ‘D-mannose’, ‘bacteriuria’, ‘pyuria’, ‘pyelocystitis’ with the appropriate Boolean modifiers (Limits: Human, English, full article). Studies were selected for the systematic review if they were clinical studies and reported original data, the number of patients using D-mannose alone or in association with other treatments, and the number of patients with symptoms of UTI/cystitis at trial entry and after the follow-up period. A total of seven studies were identified. D-mannose was given alone in two studies, and was associated with cranberry extract, Morinda citrifolia fruit extract, pomegranate extract, fructo-oligosaccharides, lactobacilli, and N-acetylcysteine in the others. All studies reported that symptoms decreased after treatment with D-mannose. Despite the limitations of the studies, the consistent results observed among all studies give support to the general findings that D-mannose may be useful in the treatment of UTI/cystitis symptoms.

Abstract
PURPOSE OF REVIEW While antibiotics have been a staple in the management and even prevention of urinary tract infections (UTIs), it is not without significant consequences due to intolerance and development of antibiotic resistant bacteria. These concerns necessitate alternatives to antibiotic use in the management of pediatric UTIs. This review seeks to evaluate non-antibiotic means of preventing UTI in the pediatric population. RECENT FINDINGS The search for preventative alternatives to antibiotics has included D-mannose, cranberry, and probiotics. These products similarly work through competitive inhibition of uropathogens in the urinary tract. Pediatric studies exist highlighting the use of cranberry extract/juice and probiotics in UTI prevention, although significant heterogeneity amongst studies have limited overarching recommendations for their use. Data of D-mannose use is extrapolated from adult literature. More studies are required in the utility of each treatment, with some emphasis on larger sample sizes and clarifications regarding dosing and formulation.

Abstract
Recurring urinary tract infections (rUTIs) are frequently caused by Escherichia coli, which invades urothelial cells and forms quiescent bacterial reservoirs. D-mannose, an inert monosaccharide, represents a notable agent for rUTI prevention; however, there is no agreement on its dosage. To provide pharmacological basis for an effective dose, we evaluated its ability to inhibit adhesion of E. coli to urothelial cells. E. coli strains isolated from the urine of a woman with recurrent urinary tract infections were selected according to adhesion capacity. Anti-adhesive efficacy and invasion were tested using the TCC-5637 urothelial cell line. The IC50 for the anti-adhesive efficacy and anti-invasion activity of D-mannose were 0.51 mg/ml and 0.30 mg/ml, respectively, both with concentration-dependent inhibition. Lastly, the biofilm interference of D-mannose was evaluated to be 50 mg/ml. D-mannose inhibited the adhesion of E. coli to urothelial cells at high concentrations, whereas inhibition of invasion occurred at much lower concentrations.

Abstract
Urinary tract infections (UTIs) are one of the most prevalent bacterial diseases worldwide. Despite the efficacy of antibiotics targeted against UTI, the recurrence rates remain significant among the patients. Furthermore, the development of antibiotic resistance is a major concern and creates a demand for alternative treatment options. D-mannose, a monosaccharide naturally found in fruits, is commonly marketed as a dietary supplement for reducing the risk for UTIs. Research suggests that supplemented D-mannose could be a promising alternative or complementary remedy especially as a prophylaxis for recurrent UTIs. When excreted in urine, D-mannose potentially inhibits Escherichia coli, the main causative organism of UTIs, from attaching to urothelium and causing infection. In this review, we provide an overview of UTIs, E. coli pathogenesis and D-mannose and outline the existing clinical evidence of D-mannose in reducing the risk of UTI and its recurrence. Furthermore, we discuss the potential effect mechanisms of D-mannose against uropathogenic E.coli.

Abstract
A healthy urinary tract contains a variety of microbes resulting in a diverse urobiome. Urobiome dysbiosis, defined as an imbalance in the microbial composition in the microenvironments along the urinary tract, is found in women with uncomplicated urinary tract infection (UTI). Historically, antibiotics have been used to address UTI. An alternative approach to uncomplicated UTI is warranted as the current paradigm fails to take urobiome dysbiosis into account and contributes to the communal problem of resistance. A whole-person, multi-modal approach that addresses vaginal and urinary tract dysbiosis may be more effective in reducing recurrent UTI. In this review, we discuss strategies that include reducing pathogenic bacteria while supporting commensal urogenital bacteria, encouraging diuresis, maintaining optimal pH levels, and reducing inflammation. Strategies for future research are suggested.

Abstract
Genito-urinary tract infections have a high incidence in the general population, being more prevalent among women than men. These diseases are usually treated with antibiotics, but very frequently, they are recurrent and lead to the creation of resistance and are associated with increased morbidity and mortality. For this reason, it is necessary to develop new compounds for their treatment. In this work, our objective is to review the characteristics of the compounds of a new formulation called Itxasol© that is prescribed as an adjuvant for the treatment of UTIs and composed of β-arbutin, umbelliferon and n-acetyl cysteine. This formulation, based on biomimetic principles, makes Itxasol© a broad-spectrum antibiotic with bactericidal, bacteriostatic and antifungal properties that is capable of destroying the biofilm and stopping its formation. It also acts as an anti-inflammatory agent, without the adverse effects associated with the recurrent use of antibiotics that leads to renal nephrotoxicity and other side effects. All these characteristics make Itxasol© an ideal candidate for the treatment of UTIs since it behaves like an antibiotic and with better characteristics than other adjuvants, such as D-mannose and cranberry extracts.
