The use of drug-target prediction can aid in identifying the specific targets of TCM, thereby revealing their bioactivity and mechanisms. The efficiency, cost-effectiveness, and powerful predictive capabilities of artificial intelligence algorithms have led to their emergence as effective tools for accelerating drug-target interaction analysis. To systematically investigate TCM interaction mechanisms, we integrated cosine‑correlation and similarity‑comparison of local network (CSLN) and molecular dynamics (MD) simulations. The CSLN algorithm predicts that 11-beta-hydroxysteroid dehydrogenase-1 (HSD11B1) serves as a common target for the synergistic effects of triptolide (TP) and glycyrrhizic acid (GA). MD simulations indicate that both TP and GA can maintain stable interactions with HSD11B1 and form a common binding hot region. Surface plasmon resonance (SPR) experiments reveal that both TP and GA can effectively bind to HSD11B1, with binding constants of 29.21 μM and 31.75 μM, respectively. When used in combination, the binding constant is 5.74 μM. The combination of CSLN and MD simulations represents an effective tool for the initial analysis and simulation of interaction patterns between TCM and their targets at the computational level. These findings enhance our understanding of the interaction mechanisms between drugs.</p>","PeriodicalId":708,"journal":{"name":"Molecular Diversity","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143957628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the 2024 Human Pneumonia Etiology Research for Child Health (PERCH) study, hMPV is the second leading common cause of pneumonia in children under five in Asia and Africa. The virus encodes nine proteins, including the essential Fusion (F) and G glycoproteins, which facilitate entry to the host cells. Currently, there are no approved vaccines or antiviral treatments for hMPV; supportive care is the primary way it is managed. Hence, this study focuses on the F protein as a therapeutic target to find a repurposable drug to fight hMPV. Refolding of the F protein and its binding to heparan sulfate enable hMPV infection. Heparin sulfate is important for hMPV binding, and we have found that cangrelor and AVN 944 can prevent the fusion of membranes. We developed a deep learning-based pharmacophore to identify potential drugs targeting hMPV, from which we could narrowed a list of 2400 FDA-approved drugs and 255 antiviral drugs to 792 and 72 drugs, respectively. We then conducted quantitative validation using the ROC curve. Further virtual screening of the drugs was performed, leading us to select the one with the highest docking score. The validation of the deep learning prediction in virtual screening Pearson correlation was done. Further, the MD simulation of these drugs confirmed that the protein-drug complex stability remained in dynamic condition.

Sesquiterpene lactone is a class of natural compounds with diverse molecular structures and known biological activities. This study aimed to explore sesquiterpene lactones for their potential as CB2 modulators using computational approaches such as molecular docking, molecular dynamics simulations (MDS), and ADMET predictions, to identify the promising candidates for neurodegenerative disease prophylactics. Out of 85 sesquiterpene lactones evaluated, podachaenin (PubChem CID: 15,828,229) exhibited the highest binding affinity to CB2 (- 12.242 kcal/mol), outperforming that of the native ligand (- 12.168 kcal/mol) and reference drugs apomorphine (- 9.482 kcal/mol), dantrolene (- 8.861 kcal/mol), and galantamine (- 9.689 kcal/mol). Hydrogen bonds as well as alkyl, Pi-alkyl, and van der Waal's interactions were present in the CB2-podachaenin complex providing structural intactness. MDS of 500 ns evaluated the stability of the protein-ligand complex and receptor structure in apo form through geometrical parameters: root mean square deviation, root mean square fluctuation, radius of gyration, solvent accessible surface area, and hydrogen bond length. Additionally, the binding free energy change calculation supplemented the initial inferences in terms of thermodynamic stability with a value of - 40.92 ± 4.56 kcal/mol. ADMET profiling also indicated favorable pharmacokinetic and pharmacodynamic properties, similar to that of the reference drugs.

Multidrug efflux pumps have been identified as crucial determinants of AMR, flushing numerous antibiotics from cells in a non-specific way, and have emerged as promising drug targets to overcome AMR. Herein, the work focuses on determining structural and mutational insights of tripartite efflux pump subunit AcrB by executing multiple sequence alignment (MSA); the residues 615 and 617 at the substrate-binding site were identified mutated from an aromatic amino acid, phenylalanine, to an aliphatic amino acid, alanine.

The identified mutations in the AcrB subunit are responsible for upregulating the activity of the AcrAB-TolC efflux pump and leading to a reduced concentration of antibiotics in the bacterial cytoplasm, ultimately increasing antibiotic resistance. Furthermore, based upon compound screening against target AcrB, 3-Hydroxyfumiquinazoline A shows competitive interaction with the antibiotic Erythromycin. A similar interaction pattern was observed between Sungucine and Cheatoglobosin D with Novobiocin while Procheatoglobosin I and Chaetoglobosin Q with Fusidic acid.

In biomedical sciences, accurate molecular property prediction is crucial for elucidating disease mechanisms, identifying potential drug candidates, and optimising various processes.

This study introduces a novel hybrid deep learning model, the Graph-Aware AURA-LSTM (Attentive Unified Representation Architecture-Long Short-Term Memory), designed to determine molecular properties with unprecedented accuracy using advanced graphical representations. AURA-LSTM combines multiple Graph Neural Network (GNN) architectures, specifically Graph Convolutional Networks (GCNs), Graph Attention Networks (GATs), and Graph Isomorphism Networks (GINs), in a parallel structure to comprehensively capture the multidimensional structural features of molecules. Within this architecture, GCNs incorporate local structural relationships, GATs apply attention mechanisms to highlight critical structural elements, and GINs capture intricate molecular details through isomorphic distinction, resulting in a richly detailed feature matrix. The feature layer then processes this BiLSTM matrix, which evaluates temporal relationships to enhance molecular feature classification. Evaluated on eight benchmark datasets, AURA-LSTM demonstrated superior performance, consistently achieving over 90% accuracy and outperforming state-of-the-art methods.
