Chem Biodivers 2024; 21:e202302064. [PMID: 38390665 DOI: 10.1002/cbdv.202302064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 02/19/2024] [Accepted: 02/20/2024] [Indexed: 02/24/2024]
Abstract
Based on our previous research, a 3D-QSAR model (q2=0.51, ONC=5, r2=0.982, F=271.887, SEE=0.052) was established to predict the inhibitory effects of triazole Schiff base compounds on Fusarium graminearum, and its predictive ability was also confirmed through the statistical parameters. According to the results of the model design, 30 compounds with superior bioactivity compared to the template molecule 4 were obtained. Seven of these compounds (DES2-6, DES9-10) with improved biological activity and readily available raw materials were successfully synthesized. Their structures were confirmed through HRMS, NMR, and single crystal X-ray diffraction analysis (DES-5). The bioactivity of the final products was investigated through an in vitro antifungal assay. There was little difference in the EC50 values between the experimental and predicted values of the model, demonstrating the reliability of the model. Especially, DES-3 (EC50=9.915 mg/L) and DES-5 (EC50=9.384 mg/L) exhibited better inhibitory effects on Fusarium graminearum compared to the standard drug (SD) triadimenol (EC50=10.820 mg/L). These compounds could serve as potential new fungicides for future research. The interaction between the final products and isocitrate lyase (ICL) was investigated through molecular docking. Compounds with R groups that have a higher electron-donating capacity were found to be biologically active.

Khan MA, Al Mamun Khan MA, Mahfuz AMUB, Sanjana JM, Ahsan A, Gupta DR, Hoque MN, Islam T. Highly potent natural fungicides identified in silico against the cereal killer fungus Magnaporthe oryzae. Sci Rep 2022; 12:20232. [PMID: 36418863 PMCID: PMC9684433 DOI: 10.1038/s41598-022-22217-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Accepted: 10/11/2022] [Indexed: 11/25/2022] Open
Abstract
Magnaporthe oryzae is one of the most notorious fungal pathogens that causes blast disease in cereals, and results in enormous loss of grain production. Many chemical fungicides are being used to control the pathogen but none of them are fully effective in controlling blast disease. Therefore, there is a demand for the discovery of a new natural biofungicide to manage the blast disease efficiently. A large number of new natural products showed inhibitory activities against M. oryzae in vitro. To find out effective biofungicides, we performed in silico molecular docking analysis of some of the potent natural compounds targeting four enzymes namely, scytalone dehydratase, SDH1 (PDB ID:1STD), trihydroxynaphthalene reductase, 3HNR (PDB ID:1YBV), trehalose-6-phosphate synthase, Tps1 (PDB ID:6JBI) and isocitrate lyase, ICL1 (PDB ID:5E9G) of M. oryzae fungus that regulate melanin biosynthesis and/or appresorium formation. Thirty-nine natural compounds that were previously reported to inhibit the growth of M. oryzae were subjected to rigid and flexible molecular docking against aforementioned enzymes followed by molecular dynamic simulation. The results of virtual screening showed that out of 39, eight compounds showed good binding energy with any one of the target enzymes as compared to reference commercial fungicides, azoxystrobin and strobilurin. Among the compounds, camptothecin, GKK1032A2 and chaetoviridin-A bind with more than one target enzymes of M. oryzae. All of the compounds except tricyclazole showed good bioactivity score. Taken together, our results suggest that all of the eight compounds have the potential to develop new fungicides, and remarkably, camptothecin, GKK1032A2 and chaetoviridin-A could act as multi-site mode of action fungicides against the blast fungus M. oryzae.

Abstract
Application of essential oils to mitigate aflatoxin B1 (AFB1) contamination in food is a current research hotspot; however, their direct incorporation may cause toxic effects, and changes in food organoleptic properties. This work aimed to synthesize novel synergistic formulation of Pinus roxburghii, Juniperus communis, and Cupressus sempervirens essential oils by mixture design assay (PJC) and encapsulation of PJC formulation into chitosan nanocomposite (Nm-PJC) with an aim to protect stored rice (Oryza sativa L., prime staple food) against fungi and AFB1 mediated loss of valuable minerals, macronutrients, and fatty acids. Nm-PJC was characterized through DLS, SEM, FTIR, and XRD analyses, along with controlled delivery from chitosan nanobiopolymer. Encapsulation of synergistic formulation into chitosan-nanomatrix improved antifungal (4.0 μL/mL), antiaflatoxigenic (3.5 μL/mL), and antioxidant activities (P < 0.05). Impairment in ergosterol and methylglyoxal biosynthesis along with in-silico-homology-modeling of major components with Ver-1 and Omt-A proteins advocated chemico-molecular interaction responsible for fungal growth inhibition and AFB1 secretion. In addition, in-situ efficacy against lipid-peroxidation, fatty acid biodeterioration, and preservation of minerals, macronutrients without affecting organoleptic attributes in rice and high mammalian safety profile (9874.23 μL/kg) suggested practical application of synergistic nanoformulation as innovative smart, and green candidate to mitigate AFB1 contamination, and shelf-life extension of stored food products.

Abstract
Fusarium spp. are ubiquitous fungi able to cause Fusarium head blight and Fusarium foot and root rot on wheat. Among relevant pathogenic species, Fusarium graminearum and Fusarium culmorum cause significant yield and quality loss and result in contamination of the grain with mycotoxins, mainly type B trichothecenes, which are a major health concern for humans and animals. Phenolic compounds of natural origin are being increasingly explored as fungicides on those pathogens. This review summarizes recent research activities related to the antifungal and anti-mycotoxigenic activity of natural phenolic compounds against Fusarium, including studies into the mechanisms of action of major exogenous phenolic inhibitors, their structure-activity interaction, and the combined effect of these compounds with other natural products or with conventional fungicides in mycotoxin modulation. The role of high-throughput analysis tools to decipher key signaling molecules able to modulate the production of mycotoxins and the development of sustainable formulations enhancing potential inhibitors’ efficacy are also discussed.

Abstract
Pluteus cervinus is a mushroom species that demands a systematic study of its medicinal values. This study aims to explore the mycochemical contents of Pluteus cervinus extract, and evaluate their anti-diabetic and antioxidant potency. Twelve organic compounds were identified using Gas Chromatogram-Mass Spectroscopy(GC-MS) analysis of the methanolic extract. All the mycochemicals identified were evaluated for their drug-likeness, pharmacokinetics and bioactivity using admetSAR and molinspiration webservers. The extract was evaluated for the inhibitory effect of α-amylase and DPPH free radical scavenging ability. To further support the anti-diabetic and antioxidant characteristic, in silico molecular docking analysis was done for all the identified mycochemicals. It was found that, 2-(3,4-dimethoxyphenyl)-N-[4-(4-methoxyphenyl)-tetrahydropyran-4-ylmethyl]-acetamide, one of the compounds in the extract shares structural similarity and comparable docking binding energy with natural α-amylase inhibitor. Further, the 2-(3,4-dimethoxyphenyl)-N-[4-(4-methoxyphenyl)-tetrahydropyran-4-ylmethyl]-acetamide also showed high binding energy with Human peroxiredoxin 5 and has a structural relationship with natural antioxidants containing tetrahydropyran derivatives.

Abstract
Lagerstroemia speciosa (L.) Pers., (Lythraceae), commonly called Banaba, is a native plant of Southeast Asia and is widely used in the treatment of diabetics, obesity, kidney diseases, and other inflammatory disorders. L. speciosa consists of several phytoconstituents like glycosides, flavones, corosolic acid, ellagic acids, triterpenes, tannins, which are reported to be present in leaves, stem, flowers, fruit, bark, and roots. This paper presents an investigation on the binding interaction of phytosterols derivatives identified from the ethanolic extract of Lagerstroemia speciosa seeds against breast cancer target protein. The ethanolic extracts Lagerstroemia speciosa seeds were analyzed via GC-MS for the identification of their chemical constituent. In silico methods are adopted to predict ADME parameters, pharmacokinetic properties, drug-likeliness, and acute toxicity of the identified phytosterols molecules. Molecular docking analysis of the phytosterols was performed against three breast cancer targets. A total of 29 compounds were identified from the extract by GC-MS analysis, among which four phytosterols derivatives namely cholesterol margarate, 7-dehydrodiosgenin, Stigmastan-3,5-diene, and γ-sitosterol have been considered for the present study. These phytosterols are identified as non-toxic, non-carcinogenic, and non-mutagenic. Molecular docking studies reveal the extent of molecular interaction with breast cancer targets. The outcomes of the investigation suggest that the phytosterols obtained from the ethanolic seed extract of Lagerstroemia speciosa could act as a promising candidate against breast cancer.
