Cannabinoid receptor ligands are renowned as being therapeutically crucial for treating diverse health disorders. Phenylspirodrimanes meroterpenoids with unique and varied structural scaffolds, which mainly reported from the Stachybotrys genus display an array of bioactivities. In this work, 114 phenylspirodrimanes chartarum were screened their CB2 agonistic potential using docking molecular dynamic simulation studies. Compound 56 revealed highest score (-11.222 kcal/mol) compared to E3R_6KPF (native agonist, gscore value -12.12 kcal/mol). The results suggest that compound binds putative binding site in good affinity involving key interacting amino acid residues similar native ligands, E3R. interactions displayed π-π stacking Phe183 hydrogen bond Thr114, Leu182, Ser285. These findings identified features these metabolites might lead design selective novel receptors. Additionally, should be further investigated a ligand.

Cancer represents one of the most prevalent causes global death. CK2 (casein kinase 2) activation boosted cancer proliferation and progression. Therefore, inhibition can have a crucial role in prohibiting progression enhancing apoptosis. Fungi gained vast interest as wealthy pool anticancer metabolites that could particularly target various progression-linked signaling pathways. Phenalenones are unique class secondary possess diverse bioactivities. In current work, inhibitory capacity 33 fungal phenalenones was explored using computational studies. After evaluating usefulness compounds enzyme inhibitors by ADMET prediction, were prepared for molecular docking CK2-α1 crystal structure (PDB: 7BU4). Molecular dynamic simulation performed on top two scoring to evaluate their binding affinity protein stability through simulated physiological environment. Compound 19 had superior co-crystallized ligand (Y49). The improved be attributed fact aliphatic chain makes additional contact with Asp120 pocket distant from active site.

The relationship between cancer and microorganisms has been extensively studied, with bacteria receiving more attention than fungi. However, fungi have shown to play a significant role in development progression. Understanding the underlying mechanisms is crucial for identifying new avenues prevention treatment. To evaluate current state of research on cancer, we conducted comprehensive bibliometric analysis. Using Web Science Core Collection database, searched English-language articles published 1998 2022. Analyzing resulting publication data, identified trends, patterns, gaps. Our analysis encompassed co-authorship networks, citation analysis, keyword co-occurrence With 8283 publications identified, averaging 331.32 per year, our findings highlight China, United States, India, Japan, Germany as top contributing countries. Chinese Academy Sciences, Sun Yat-Sen University, University São Paulo emerged most productive institutions. Key themes literature included "cancer," "cytotoxicity," "apoptosis," "metabolites," "fungus." Recent trends indicate increased interest keywords such "green synthesis," "molecular docking," "anticancer activity," "antibacterial," "anticancer," "silver nanoparticles." study provides assessment landscape field offering insights into collaborative directions, emerging hotspots. growing rate demonstrates rising topic, while leading countries, institutions, serves valuable resource researchers, policymakers, funders interested supporting investigations fungi-derived compounds potential anti-cancer agents.

The current study explored the protective potential of kaempferol 3-sophoroside-7-glucoside (KSG) against acute lung injury (ALI). Pre-treatment with KSG effectively secured mice from ALI and showed similar efficaciousness to dexamethasone. markedly increased survival rate alleviated pathological lesions induced by lipopolysaccharide (LPS). Furthermore, attenuated differential total cell counts in BALF (bronchoalveolar lavage fluid) MPO (myeloperoxidase) activity. counteracted NF-κB (nuclear factor-κB) activation significantly ameliorated downstream inflammatory cytokine, TNF-α (tumor necrosis factor-α). Simultaneously, suppressed over-expression NLRP3 (NOD-like receptor protein 3), caspase-1, pro-inflammatory cytokine interleukin IL-1β (interleukine-1β) prohibited elevation pyroptotic parameter GSDMD-N (N-terminal domain gasdermin D) LPS challenge. In addition, enhanced Nrf2 (nuclear-factor erythroid-2-related factor) HO-1 (heme-oxygenase-1) expression. Meanwhile, mitigated lipid peroxidative markers (malondialdehyde, carbonyl 4-hydroxynonenal) boosted endogenous antioxidants (superoxide dismutase/reduced glutathione/catalase) tissue. silico analyses revealed that disrupts Keap1-Nrf2 protein–protein interactions binding KEAP1 domain, consequently activating Nrf2. Specifically, molecular docking demonstrated superior affinity compared reference inhibitor, scores −9.576 −6.633 Kcal/mol, respectively. Additionally, MM-GBSA free energy (−67.25 Kcal/mol) surpassed inhibitor (−56.36 Kcal/mol). MD simulation analysis KSG-KEAP1 complex exhibits substantial stable various amino acids over a duration 100 ns. These findings anti-inflammatory anti-oxidative modulatory efficiencies LPS-induced encouraged future research clinical applications as strategy for

Phenaloenones are structurally unique aromatic polyketides that have been reported in both microbial and plant sources. They possess a hydroxy perinaphthenone three-fused-ring system exhibit diverse bioactivities, such as cytotoxic, antimicrobial, antioxidant, anti-HIV properties, tyrosinase, α-glucosidase, lipase, AchE (acetylcholinesterase), indoleamine 2,3-dioxygenase 1, angiotensin-I-converting enzyme, tyrosine phosphatase inhibition. Moreover, they rich nucleophilic nucleus has inspired many chemists biologists to synthesize more of these related derivatives. The current review provides an overview the phenalenones with fungal origin, including their structures, sources, biosynthesis, bioactivities. than 135 metabolites listed, 71 references cited. SuperPred, artificial intelligence (AI) webserver, was used predict potential targets for selected phenalenones. Among targets, we chose human glucose transporter 1 (hGLUT1) extensive silico study, it shows high probability model accuracy. them, aspergillussanones C (60) G possessed highest negative docking scores −15.082 −14.829 kcal/mol, respectively, compared native inhibitor 5RE (score: −11.206 kcal/mol). MD (molecular dynamics) simulation revealed stability complexes GLUT1 at 100 ns. virtual screening study results open up new therapeutic approach by using some hGLUT1 inhibitors, which might be target cancer therapy.
