Abstract
BACKGROUND Epicoccum sorghinum is a pathogenic fungus that causes leaf spot in a wide range of plants, including maize, and synthesizes the mycotoxin tenuazonic acid (TEA), which is carcinogenic. Despite the relevant economic and yield losses caused by E. sorghinum worldwide, methods for the control of this pathogen are lacking. RESULTS In this work, the efficacy of Bacillus-produced dipicolinic acid (DPA) for control of E. sorghinum was evaluated using in vitro and in vivo assays, and compared with the efficacy of three commercial fungicides, including carbendazim, prochloraz, and thiram. DPA inhibited E. sorghinum mycelial growth, and conidia germination, and produced important alterations in E. sorghinum hyphae. Interestingly, 10 mM DPA reduced TEA biosynthesis by 86.6%. Although DPA rapidly degraded on maize leaves, 10 mM DPA showed higher preventive (67.4% lesion length inhibition) and inhibitory (89.5% lesion length inhibition) efficacies for the control of E. sorghinum on maize leaves compared to the commercial fungicides. CONCLUSIONS Collectively, this study presents the first method for the control of E. sorghinum on maize and demonstrates that DPA application is a suitable approach to inhibit E. sorghinum symptoms in plants and TEA biosynthesis. © 2024 Society of Chemical Industry.

Abstract
Cryptosporidiosis is an opportunistic, globally distributed parasitic disease. Whereas Cryptosporidium causes asymptomatic infection and diarrhea in healthy people, it may lead to severe illness in immunocompromised individuals. Limited, effective therapeutic alternatives are available against cryptosporidiosis in those categories of patients. So, we are in urgent need of better drugs for the treatment of cryptosporidiosis. Fifty male Swiss albino mice were used. Mice were grouped into five groups of ten mice each. Group I was left uninfected, and four groups were infected with 1000 oocysts of cryptosporidium. The first infected group was left untreated. The remaining three-infected groups received nitazoxanide (NTZ), eugenol, and eugenol + NTZ, respectively, on the 6th day post infection (dpi) for five days. Mice were sacrificed on the 30th dpi. The efficacy of treatment was evaluated using parasitological, biochemical, and histopathological parameters. Combination therapy of eugenol with NTZ caused a significant reduction of the number of oocysts secreted in stool and improved cryptosporidiosis-induced liver injury manifested by the restoration of normal levels of liver enzymes (ALT and AST). Treatment with eugenol-NTZ combination maintained a well-balanced antioxidant status, as evidenced by a reduced level of nitric oxide (NO) and increased antioxidant Superoxide dismutase (SOD) enzyme activity. Moreover, the combination of eugenol with NTZ resulted in the restoration of the normal morphology of intestinal villi, crypts, and muscularis mucosa. Based on the findings extracted from the present work, we can conclude that eugenol is a complementary therapeutic when used with NTZ in the treatment of cryptosporidiosis. The addition of eugenol to NTZ in the treatment of cryptosporidiosis synergized the effect of NTZ, causing a greater reduction of the number of shedded oocysts, improving liver enzyme levels, and restoring normal intestinal pathology. Therefore, we presume that eugenol's antioxidant capacity accounts for the protective effect seen in the current study. We suggest eugenol as a supplemental chemotherapeutic agent with good therapeutic potential and high levels of safety in the treatment of cryptosporidiosis based on the findings of the current study.

Abstract
BACKGROUND Kiwifruit is highly susceptible to fungal pathogens, such as Botrytis cinerea, which reduce crop production and quality. In this study, dipicolinic acid (DPA), which is one of the main components of Bacillus spores, was evaluated as a new elicitor to enhance kiwifruit resistance to B. cinerea. RESULTS DPA enhances antioxidant capacity and induces the accumulation of phenolics in B. cinerea-infected 'Xuxiang' kiwifruit. The contents of the main antifungal phenolics in kiwifruit, including caffeic acid, chlorogenic acid and isoferulic acid, increased after DPA treatment. DPA enhanced H2 O2 levels after 0 and 1 days, which promoted catalase (CAT) and superoxide dismutase (SOD) activities, reducing long-term H2 O2 levels. DPA promoted the up-regulation of several kiwifruit defense genes, including CERK1, MPK3, PR1-1, PR1-2, PR5-1 and PR5-2. Furthermore, DPA at 5 mM inhibited B. cinerea symptoms in kiwifruit (95.1% lesion length inhibition) more effectively than the commercial fungicides carbendazim, difenoconazole, prochloraz and thiram. CONCLUSIONS The antioxidant properties of DPA and the main antifungal phenolics of kiwifruit were examined for the first time. This study uncovers new insights regarding the potential mechanisms used by Bacillus species to induce disease resistance. © 2023 Society of Chemical Industry.

Microorganisms 2022; 10:microorganisms10040730. [PMID: 35456781 PMCID: PMC9024752 DOI: 10.3390/microorganisms10040730] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 03/25/2022] [Accepted: 03/26/2022] [Indexed: 02/04/2023] Open
Abstract
Dipicolinic acid (DPA) is an aromatic dicarboxylic acid that mediates heat-stability and is easily biodegradable and non-toxic. Currently, the production of DPA is fossil-based, but bioproduction of DPA may help to replace fossil-based plastics as it can be used for the production of polyesters or polyamides. Moreover, it serves as a stabilizer for peroxides or organic materials. The antioxidative, antimicrobial and antifungal effects of DPA make it interesting for pharmaceutical applications. In nature, DPA is essential for sporulation of Bacillus and Clostridium species, and its biosynthesis shares the first three reactions with the L-lysine pathway. Corynebacterium glutamicum is a major host for the fermentative production of amino acids, including the million-ton per year production of L-lysine. This study revealed that DPA reduced the growth rate of C. glutamicum to half-maximal at about 1.6 g·L−1. The first de novo production of DPA by C. glutamicum was established by overexpression of dipicolinate synthase genes from Paenibacillus sonchi genomovar riograndensis SBR5 in a C. glutamicum L-lysine producer strain. Upon systems metabolic engineering, DPA production to 2.5 g·L−1 in shake-flask and 1.5 g·L−1 in fed-batch bioreactor cultivations was shown. Moreover, DPA production from the alternative carbon substrates arabinose, xylose, glycerol, and starch was established. Finally, expression of the codon-harmonized phosphite dehydrogenase gene from P. stutzeri enabled phosphite-dependent non-sterile DPA production.

Abstract
For centuries, fermented soy foods have been dietary staples in Asia and, now, in response to consumer demand, they are available throughout the world. Fermentation bestows unique flavors, boosts nutritional values and increases or adds new functional properties. In this review, we describe the functional properties and underlying action mechanisms of soy-based fermented foods such as Natto, fermented soy milk, Tempeh and soy sauce. When possible, the contribution of specific bioactive components is highlighted. While numerous studies with in vitro and animal models have hinted at the functionality of fermented soy foods, ascribing health benefits requires well-designed, often complex human studies with analysis of diet, lifestyle, family and medical history combined with long-term follow-ups for each subject. In addition, the contribution of the microbiome to the bioactivities of fermented soy foods, possibly mediated through direct action or bioactive metabolites, needs to be studied. Potential synergy or other interactions among the microorganisms carrying out the fermentation and the host's microbial community may also contribute to food functionality, but the details still require elucidation. Finally, safety evaluation of fermented soy foods has been limited, but is essential in order to provide guidelines for consumption and confirm lack of toxicity.

Abstract
Abstract
Dipicolinic acid (DPA) is a multi-functional agent for cosmetics, antimicrobial products, detergents, and functional polymers. The aim of this study was to design a new method for producing DPA from renewable material. The Bacillus subtilis spoVF operon encodes enzymes for DPA synthase and the part of lysine biosynthetic pathway. However, DPA is only synthesized in the sporulation phase, so the productivity of DPA is low level. Here, we report that DPA synthase was expressed in vegetative cells, and DPA was produced in the culture medium by replacement of the spoVFA promoter with other highly expressed promoter in B. subtilis vegetative cells, such as spoVG promoter. DPA levels were increased in the culture medium of genetically modified strains. DPA productivity was significantly improved up to 29.14 g/L in 72 h culture by improving the medium composition using a two-step optimization technique with the Taguchi methodology.

2-Amino-3-hydroxypyridinium dioxido(pyridine-2,6-dicarboxylato-κ(3)O(2),N,O(6))vanadate(V), (C5H7N2O)[V(C7H3NO4)O2] or [H(amino-3-OH-py)][VO2(dipic)], (I), was prepared by the reaction of VCl3 with dipicolinic acid (dipicH2) and 2-amino-3-hydroxypyridine (amino-3-OH-py) in water. The compound was characterized by elemental analysis, IR spectroscopy and X-ray structure analysis, and consists of an anionic [VO2(dipic)](-) complex and an H(amino-3-OH-py)(+) counter-cation. The V(V) ion is five-coordinated by one O,N,O'-tridentate dipic dianionic ligand and by two oxide ligands. Thermal decomposition of (I) in the presence of polyethylene glycol led to the formation of nanoparticles of V2O5. Powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of the synthesized powder.

Abstract
Alzheimer's disease is a neurodegenerative disorder characterized by the development of intracellular neurofibrillary tangles, deposition of extracellular amyloid beta (Aβ) plaques, along with a disruption of transition metal ion homeostasis in conjunction with oxidative stress. Spectroscopic, transmission electron microscopy, and scanning electron microscopy imaging studies show that 1 (pyclen) is capable of both preventing and disrupting Cu(2+) induced AB(1-40) aggregation. The pyridine backbone of 1 engenders antioxidant capacity, as shown by cellular DCFH-DA (dichlorodihydrofluorescein diacetate) assay in comparison to other N-heterocyclic amines lacking this aromatic feature. Finally, 1 prevents cell death induced by oxidative stress as shown by the Calcein AM assay. The results are supported using density functional theory studies which show that the pyridine backbone is responsible for the antioxidant capacity observed.

Abstract
In vitro antioxidant activity for 12 stannoxanes derived from Ph3SnCl (compounds 1-3), Ph2SnCl2 (compounds 4-6), Bu3SnCl (compounds 7-9), and Bu2SnCl2 (compounds 10-12), was assayed qualitatively by the chromatographic profile with 1,1-diphenyl-2-picrylhydrazil (DPPH) method and by two quantitative methods: the DPPH radical scavenging activity and Ferric-Reducing Antioxidant Power (FRAP) assays. The results were compared with those obtained with the starting materials 2-pyridine- carboxylic acid (I), 3-pyridinecarboxylic acid (II) and 4-pyridinecarboxylic acid (III), as well as with standard compounds, such as vitamin C and vitamin E, respectively. The in vitro antiradical activity with DPPH of diphenyltin derivative 5 showed a very similar behavior to vitamin C at a 20 μg/mL concentration, whereas according to the FRAP method, compound 8 was better. This difference is due to the mechanism of the antioxidant process. The Structure-Activity Relationships (SAR) for both methods is also reported.

Abstract
Although ceruloplasmin (CP), a copper containing metalloenzyme, possesses antioxidant properties (e.g. ferroxidase activity), elevated circulating CP is associated with cardiovascular disease (CVD). This ambivalence is possibly due to the capacity of CP, via its coppers, to promote vasculopathic effects that include lipid oxidation, negation of nitric oxide bioactivity and endothelial cell apoptosis. In turn, these effects that are mediated by increased formation of reactive oxygen species (ROS), such as superoxide and hydrogen peroxide. There is also evidence that risk factors for CVD (in particular, diabetes mellitus and hyperhomocysteinaemia) may augment the vasculopathic impact of CP. In turn, it appears that ROS disrupt copper binding to CP, thereby impairing its normal protective function while liberating copper which in turn may promote oxidative pathology. The objective of this review, therefore, is to consider the epidemiology and pathophysiology of CP in relation to CVD, with particular emphasis on the relationship between CP and oxidative stress.

Abstract
1. In the present study, we have examined the ability of kolaviron, a natural biflavonoid from Garcinia kola seeds, to prevent the susceptibility of rat serum lipoprotein to undergo oxidative modification in vitro and ex vivo. In addition, its ability to chelate metal ions and mitigate iron/ascorbate-induced damage to microsomal lipids was investigated. 2. Lipoprotein resistance to copper-induced oxidation was highly improved in rats treated with kolaviron (100 mg/kg) for 7 days, as demonstrated by a significant increase in lag time compared with control. A significant (P < 0.05) decrease in area under the curve (AUC) and slope of propagation was observed in kolaviron-treated rats compared with control. Conjugated dienes formed after 240 min of lipoprotein oxidation were markedly decreased in kolaviron-treated rats compared with controls. Malondialdehyde concentrations were significantly reduced in the serum lipoproteins of kolaviron-treated rats with an attendant significant increase in the total anti-oxidant activity compared with control. 3. In vitro, kolaviron (10-60 micromol/L) inhibited the Cu2+-induced oxidation of rat serum lipoprotein in a concentration-dependent manner. Kolaviron, at 20 and 60 micromol/L, produced 48 and 87% inhibition of oxidation of lipoprotein, respectively. Compared with control, kolaviron, at 10 and 20 micromol/L, resulted in 29 and 47% decreases in AUC, respectively. In addition, kolaviron (10 micromol/L) elicited a 53% increase in lag time, whereas 40 and 60 micromol/L kolaviron produced 38 and 88% decreases in slope, respectively. 4. Kolaviron effectively prevented microsomal lipid peroxidation induced by iron/ascorbate in a concentration-dependent manner. Kolaviron at the highest dose tested (90 micromol/L) had a significant chelating effect on Fe2+ (78%). 5. In conclusion, our data demonstrate that kolaviron protects against the oxidation of lipoprotein, presumably by mechanisms involving metal chelation and anti-oxidant activity, and, as such, may be of importance in relation to the development of atherosclerosis.

Abstract
Antioxidant action of eugenol compounds was analyzed in relation to the role of transition metal. Iron-mediated lipid peroxidation and autooxidation of Fe2+ ion were inhibited markedly by isoeugenol, and less effectively by eugenol. Copper-dependent oxidation of low density lipoprotein (LDL) was potently inhibited by eugenol and isoeugenol to the same extent: eugenol compounds showed protective effects by prolonging lag phase and by suppressing propagation rate in the absence and presence of alpha-tocopherol. Inhibition of LDL oxidation by eugenol compounds was closely related to activities reducing copper and scavenging a stable radical, 1,1'-diphenyl-2-picrylhydrazyl (DPPH). Antioxidant properties of eugenol compounds can be explained by forming complexes with reduced metals. Potent inhibitory effect of isoeugenol on lipid peroxidation may be related to the decreased formation of perferryl ion or the iron-oxygen chelate complex as the initiating factor of lipid peroxidation by keeping iron at a reduced state. Inhibition of LDL oxidation by eugenol compounds is due to the suppression of free radical cascade of lipid peroxidation in LDL by reducing copper ion.
