Anticandidal Activity of In Situ Methionine γ-Lyase-Based Thiosulfinate Generation System vs. Synthetic Thiosulfinates. Pharmaceuticals (Basel) 2023; 16:1695. [PMID: 38139821 PMCID: PMC10748059 DOI: 10.3390/ph16121695] [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: 10/19/2023] [Revised: 11/19/2023] [Accepted: 12/03/2023] [Indexed: 12/24/2023] Open
Abstract
Candida albicans and non-albicans Candida species are a common cause of human mucosal infections, as well as bloodstream infections and deep mycoses. The emergence of resistance of Candida spp. to antifungal drugs used in practice requires the search for new antimycotics. The present study unravels the antifungal potential of the synthetic dialk(en)ylthiosulfinates in comparison with an enzymatic in situ methionine γ-lyase-based thiosulfinate generation system (TGS). The kinetics of the TGS reaction, namely, the methionine γ-lyase-catalyzed β-elimination of S-alk(en)yl-L-cysteine sulfoxides, was investigated via 1H NMR spectroscopy for the first time, revealing fast conversion rates and the efficient production of anticandidal dialk(en)ylthiosulfinates. The anticandidal potential of this system vs. synthetic thiosulfinates was investigated through an in vitro assay. TGS proved to be more effective (MIC range 0.36-1.1 μg/mL) than individual substances (MIC range 0.69-3.31 μg/mL). The tested preparations had an additive effect with the commercial antimycotics fluconazole, amphotericin B and 5-flucytosine demonstrating a fractional inhibitory coefficient index in the range of 0.5-2 μg/mL. TGS can be regarded as an attractive candidate for the targeted delivery of antimycotic thiosulfinates and for further implementation onto medically implanted devices.

Abstract
Invasive aspergillosis (IA) is a life-threatening fungal disease that causes high morbidity and mortality in immunosuppressed patients. Early and accurate diagnosis and treatment of IA remain challenging. Given the broad range of non-specific clinical symptoms and the shortcomings of current diagnostic techniques, most patients are either diagnosed as “possible” or “probable” cases but not “proven”. Moreover, because of the lack of sensitive and specific tests, many high-risk patients receive an empirical therapy or a prolonged treatment of high-priced antifungal agents, leading to unnecessary adverse effects and a high risk of drug resistance. More precise diagnostic techniques alongside a targeted antifungal treatment are fundamental requirements for reducing the morbidity and mortality of IA. Monoclonal antibodies (mAbs) with high specificity in targeting the corresponding antigen(s) may have the potential to improve diagnostic tests and form the basis for novel IA treatments. This review summarizes the up-to-date application of mAb-based approaches in assisting IA diagnosis and therapy.

Abstract
Allicin, a thiosulfonate extract from freshly minced garlic, has been reported to have various biological effects on different organs and systems of animals and human. It can reduce oxidative stress, inhibit inflammatory response, resist pathogen infection and regulate intestinal flora. In addition, dozens of studies also demonstrated allicin could reduce blood glucose level, protect cardiovascular system and nervous system, and fight against cancers. Allicin was widely used in disease prevention and health care. However, more investigations on human cohort study are needed to verify the biological or clinical effects of allicin in the future. In this review, we summarized the biological effects of allicin from previous outstanding and valuable studies and provided useful information for future studies on the health effects of allicin.

Abstract
Pyridoxal 5'-phosphate-dependent methionine γ-lyase from Citrobacter freundii (MGL, EC 4.4.1.11) is studied as an antitumor enzyme and in combination with substrates as an antibacterial agent in enzyme pro-drug therapy. For the possibility of in vivo trials, two mutant forms, C115H MGL and V358Y MGL, were encapsulated into polyionic vesicles (PICsomes). Five pairs of polymers with the number of polymer chain units 20, 50, 70, 120, and 160 were synthesized. The effect of polymer length-PEGylated poly-l-aspartic acid and poly-l-lysine-on the degree of MGL incorporation into PICsomes and their size was investigated. Encapsulation of proteins in PICsomes is a rather new technique. Our data demonstrated that the length of the polymers and, therefore, the ratio of the hydrophobic and hydrophilic fragments most likely should be selected individually for each protein to be encapsulated. The efficiency of encapsulation of MGL mutant forms into PICsomes was up to 11%. The hydrodynamic diameter and surface potential of hollow and MGL-loaded PICsomes were evaluated by the dynamic light scattering method. The size and morphology of the PICsomes were determined by atomic force microscopy. The most acceptable for further in vivo studies were PICsomes20 with a size of 57-64 nm, PICsomes70 of 50-90 nm, and PICsomes120 of 100-105 nm. The analysis of the steady-state parameters has demonstrated that both mutant forms retained their catalytic properties inside the nanoparticles. The release study of the enzymes from PICsomes revealed that about 50% of the enzymes remained encapsulated in PICsomes70 and PICsomes120 after 24 h. Based on the data obtained, the most promising for in vivo studies are PICsomes70 and PICsomes120.

Abstract
OBJECTIVES Inhibitory effect of allicin with broad-spectrum antimicrobial activity on A. fumigatus and the regulation mechanism of inflammation and autophagy in vitro and in vivo. METHODS The corresponding concentration of allicin was prepared according to the needs of the experiment. In vitro, 2 ml 5 × 104 of fungal spores suspension was added to the 6-well plate per hole, and different final concentrations of allicin (1 μl/ml, 2.5 μl/ml, 5 μl/ml, 10 μl/ml, 20 μl/ml, 30 μl/ml) were added. The fungal spores were stained by fluorescent dye SYTO 9 (green) every day, and the spore germination inhibition was detected by flow cytometry in different PH. RAW264.7 cells were cultured and stimulated by A. fumigatus spores for 3 h, then allicin solution was added. Then some cells were stained with ROS probe (green) and hochest33342 (blue). The effect of allicin on ROS was observed by fluorescence microscope. The other part of cells extracted protein from cell lysate and detected the effect of allicin on inflammatory factors and autophagy by Western-blotting. The green and red spots of RAW264.7 cells stably transfected with GFP-RFP-LC3 were observed by fluorescence microscopy. In vivo, A. fumigatus spore was injected intratracheally into mice, then allicin was injected intravenously at a concentration of 5 mg/kg/day for 7 consecutive days. The survival status, pulmonary fungal load and weight of mice was recorded continuously for 30 days and detected the changes of lung by pathological examination and immunohistochemistry. RESULTS In vitro, allicin significantly inhibited the spore germination of A. fumigatus within 24 h in a dose-dependent manner and it had a stable inhibition on the spore germination of A. fumigatus in acidic environment. Cell experiments showed that allicin inhibited intracellular spore germination by inhibiting ROS production, inflammation and autophagy. In the animal experiment, the survival rate and body weight of allicin injection group were higher than that of non injection group, while the spore load of lung was lower than that of non injection group (P < 0.05). CONCLUSIONS These results support that allicin reduces inflammation and autophagy resistance to A. fumigatus infection, It also provides a possible treatment for Aspergillus infectious diseases, i.e. early anti-inflammation, antibiotics or drugs that inhibit excessive autophagy.

Abstract
Lung disease caused by Pseudomonas aeruginosa is the leading reason for death in cystic fibrosis patients. Therapeutic efficacy of the pharmacological pairs, the naked/encapsulated mutant form of Citrobacter freundii methionine γ-lyase and the substrates, sulfoxides of S-substituted l-cysteine, generating thiosulfinates, was evaluated on the murine model of experimental sepsis caused by the multidrug-resistant P. aeruginosa 203-2 strain. The pairs containing the naked enzyme and substrates did not have antibacterial activity. The treatment of mice with the pair encapsulated enzyme and S-methyl-l-cysteine sulfoxide, generating dimethyl thiosulfinate, led to a complete recovery of the animals of the model, with the infecting dose equal to LD50. The pair generating diallyl thiosulfinate (allicin) proved to be less effective. So, the substituents, attached to the thiosulfinate moiety, affect the antibacterial activity of thiosulfinates against P. aeruginosa.

Abstract
The increasing incidence in systemic fungal infections in humans has increased focus for the development of fungal vaccines and use of monoclonal antibodies. Invasive mycoses are generally difficult to treat, as most occur in vulnerable individuals, with compromised innate and adaptive immune responses. Mortality rates in the setting of our current antifungal drugs remain excessively high. Moreover, systemic mycoses require prolonged durations of antifungal treatment and side effects frequently occur, particularly drug-induced liver and/or kidney injury. The use of monoclonal antibodies with or without concomitant administration of antifungal drugs emerges as a potentially efficient treatment modality to improve outcomes and reduce chemotherapy toxicities. In this review, we focus on the use of monoclonal antibodies with experimental evidence on the reduction of fungal burden and prolongation of survival in in vivo disease models. Presently, there are no licensed monoclonal antibodies for use in the treatment of systemic mycoses, although the potential of such a vaccine is very high as indicated by the substantial promising results from several experimental models.

Abstract
Antibodies represent an important element in the adaptive immune response and a major tool to eliminate microbial pathogens. For many bacterial and viral infections, efficient vaccines exist, but not for fungal pathogens. For a long time, antibodies have been assumed to be of minor importance for a successful clearance of fungal infections; however this perception has been challenged by a large number of studies over the last three decades. In this review, we focus on the potential therapeutic and prophylactic use of monoclonal antibodies. Since systemic mycoses normally occur in severely immunocompromised patients, a passive immunization using monoclonal antibodies is a promising approach to directly attack the fungal pathogen and/or to activate and strengthen the residual antifungal immune response in these patients.

Abstract
S-Alk(en)ylcysteine sulfoxides are sulfur-containing natural products characteristic of the genus Allium. Both the flavor and medicinal properties of Allium plants are attributed to a wide variety of sulfur-containing compounds that are generated from S-alk(en)ylcysteine sulfoxides. Previous radiotracer experiments proposed that S-alk(en)ylcysteine sulfoxides are biosynthesized from glutathione. The recent identification of γ-glutamyl transpeptidases and a flavin-containing S-oxygenase involved in the biosynthesis of S-allylcysteine sulfoxide (alliin) in garlic (Allium sativum) provided insights into the reaction order of deglutamylation and S-oxygenation together with the localization of the biosynthesis, although the rest of the enzymes in the pathway still await discovery. In intact plants, S-alk(en)ylcysteine sulfoxides are stored in the cytosol of storage mesophyll cells. During tissue damage, the vacuolar enzyme alliinase contacts and hydrolyzes S-alk(en)ylcysteine sulfoxides to produce the corresponding sulfenic acids, which are further converted into various sulfur-containing bioactive compounds mainly via spontaneous reactions. The formed sulfur-containing compounds exhibit bioactivities related to pathogen defense, the prevention and alleviation of cancer and cardiovascular diseases, and neuroprotection. This review summarizes the current understanding of the occurrence, biosynthesis, and alliinase-triggered chemical conversion of S-alk(en)ylcysteine sulfoxides in Allium plants as well as the impact of S-alk(en)ylcysteine sulfoxides and their derivatives on medicinal, food, and agricultural sciences.

Abstract
Allicin (diallyl thiosulfinate) from garlic is a highly potent natural antimicrobial substance. It inhibits growth of a variety of microorganisms, among them antibiotic-resistant strains. However, the precise mode of action of allicin is unknown. Here, we show that growth inhibition of Escherichia coli during allicin exposure coincides with a depletion of the glutathione pool and S-allylmercapto modification of proteins, resulting in overall decreased total sulfhydryl levels. This is accompanied by the induction of the oxidative and heat stress response. We identified and quantified the allicin-induced modification S-allylmercaptocysteine for a set of cytoplasmic proteins by using a combination of label-free mass spectrometry and differential isotope-coded affinity tag labeling of reduced and oxidized thiol residues. Activity of isocitrate lyase AceA, an S-allylmercapto-modified candidate protein, is largely inhibited by allicin treatment in vivo. Allicin-induced protein modifications trigger protein aggregation, which largely stabilizes RpoH and thereby induces the heat stress response. At sublethal concentrations, the heat stress response is crucial to overcome allicin stress. Our results indicate that the mode of action of allicin is a combination of a decrease of glutathione levels, unfolding stress, and inactivation of crucial metabolic enzymes through S-allylmercapto modification of cysteines.

Abstract
The last decade has witnessed a renewed interest in antimicrobial agents. Plants have received particular attention and frequently rely on the spontaneous enzymatic conversion of an inactive precursor to an active agent. Such two-component substrate/enzyme defence systems can be reconstituted ex vivo. Here, the alliin/alliinase system from garlic seems to be rather effective against Saccharomyces cerevisiae, whilst the glucosinolate/myrosinase system from mustard appears to be more active against certain bacteria. Studies with myrosinase also confirm that enzyme and substrate can be added sequentially. Ultimately, such binary systems hold considerable promise and may be employed in a medical or agricultural context.

Abstract
Increased incidence of fungal infections in the immunocompromised individuals and fungi-mediated allergy and inflammatory conditions in immunocompetent individuals is a cause of concern. Consequently, there is a need for efficient therapeutic alternatives to treat fungal infections and inflammation. Several studies have demonstrated that antibodies or immunoglobulins have a role in restricting the fungal burden and their clearance. However, based on the data from monoclonal antibodies, it is now evident that the efficacy of antibodies in fungal infections is dependent on epitope specificity, abundance of protective antibodies, and their isotype. Antibodies confer protection against fungal infections by multiple mechanisms that include direct neutralization of fungi and their antigens, inhibition of growth of fungi, modification of gene expression, signaling and lipid metabolism, causing iron starvation, inhibition of polysaccharide release, and biofilm formation. Antibodies promote opsonization of fungi and their phagocytosis, complement activation, and antibody-dependent cell toxicity. Passive administration of specific protective monoclonal antibodies could also prove to be beneficial in drug resistance cases, to reduce the dosage and associated toxic symptoms of anti-fungal drugs. The longer half-life of the antibodies and flexibilities to modify their structure/forms are additional advantages. The clinical data obtained with two monoclonal antibodies should incite interests in translating pre-clinical success into the clinics. The anti-inflammatory and immunoregulatory role of antibodies in fungal inflammation could be exploited by intravenous immunoglobulin or IVIg.

Abstract
OBJECTIVE(S) Garlic (Allium sativum L. family Liliaceae) is well known in Iran and its leaves, flowers, and cloves have been used in traditional medicine for a long time. Research in recent decades has shown widespread pharmacological effects of A. sativum and its organosulfur compounds especially Allicin. Studies carried out on the chemical composition of the plant show that the most important constituents of this plant are organosulfur compounds such as allicin, diallyl disulphide, S-allylcysteine, and diallyl trisulfide. Allicin represents one of the most studied among these naturally occurring compounds. In addition to A. sativum, these compounds are also present in A. hirtifolium (shallot) and have been used to treat various diseases. This article reviews the pharmacological effects and traditional uses of A. sativum, A. hirtifolium, and their active constituents to show whether or not they can be further used as potential natural sources for the development of novel drugs. MATERIALS AND METHODS For this purpose, the authors went through a vast number of sources and articles and all needed data was gathered. The findings were reviewed and classified on the basis of relevance to the topic and a summary of all effects were reported as tables. CONCLUSION Garlic and shallots are safe and rich sources of biologically active compounds with low toxicity. Further studies are needed to confirm the safety and quality of the plants to be used by clinicians as therapeutic agents.
