Top analogs, selected based on pChembL values below 6.000nM, underwent molecular docking targeting Human Eg5. The top five analogs from this study (Compound 9794, Compound 8592, Compound 9786, Compound 2744, and Compound 3246) demonstrated strong binding energies and interactions with key amino acids (GLU 116, GLU 117, and ARG 119). MMGBSA analysis revealed comparable affinities to the co-crystallized ligand, suggesting the top analogs' potential as Human Eg5 inhibitors. Induced fit docking highlighted Compound 9786's superior efficacy. Quantum Polarized Ligand Docking indicated promising scores for Compounds 8592 and 9786. ADMET predictions offered insights into pharmacological properties, with all compounds predicted to be HIA-positive and non-carcinogenic.

Contemplating the significance of MMP-12, a number of MMP-12 inhibitors were designed, synthesized and tested throughout the world but the non-selective nature of most of those molecules can lead to adverse drug interactions. In contradiction, the dibenzofuran (DBF) and dibenzothiophene (DBT) derivatives showed highly potent and selective MMP-12 inhibition. Therefore, to identify the prime molecular and structural attributes that are affecting the MMP-12 inhibitory activity, the linear discriminant analysis (LDA), Bayesian classification, recursive partitioning, and SARpy analysis were performed to extract the prime attributes of these DBFs and DBTs affecting MMP-12 inhibition. These studies suggested that substructures like isopropyl carboxylic acid, 5-methyl furan, 1,2,4-oxadiazole, and DBT moieties can impart moderate to high contribution for MMP-12 inhibition. Importantly, the outcomes of the current studies were also in agreement with our regression-based study performed earlier. Furthermore, the molecular docking-mediated virtual screening of DBT and DBF analogs of the ChEMBL database demonstrated the viability of other DBT and DBF analogs to become potential MMP-12-selective inhibitors. The molecular dynamics (MD) simulation study of hit molecules also showed the potential of the combination of phosphonic acid ZBG and DBF P1' substituent for effective anchoring/binding at the MMP-12 active site.

Despite the numerous advancements in therapeutic options, no approved vaccine is currently available for this particular bacterium. Consequently, this study focused on creating a rational vaccine design using bioinformatics tools. Three outer membrane proteins with immunogenic potential and properties of good vaccine candidates were used to select epitopes based on good antigenic properties, non-allergenicity, high binding scores, and a low IC50 value. A multi-epitope peptide (MEP) construct was created by sequentially linking the epitopes using suitable linkers. ClusPro 2.0 and C-ImmSim web servers were used for docking analysis with TLR2/TLR4 and immune response respectively. The Ramachandran plot showed an accurate model of the MEP with 100% residue in the most favored and allowed regions. The construct was highly antigenic, stable, non-allergenic, non-toxic, and soluble, and showed maximum population coverage. Additionally, molecular docking demonstrated strong binding between the designed MEP vaccine and TLR2/TLR4. In silico immunological simulations showed significant increases in T-cell and B-cell populations. Finally, codon optimization and in silico cloning were conducted using the pET-28a (+) plasmid vector to evaluate the efficiency of the expression of vaccine peptide in the host organism (<i>Escherichia coli</i>).

The existing reliance on a solitary medication (Praziquantel) gives rise to concerns about drug resistance and possible side effects. The exploration of alternative treatments is crucial to meet the demand for more efficient, safer, and cost-effective remedies, guaranteeing continuous control and eradication initiatives while reducing the risk of drug resistance. To address these issues, we employed a structure-based drug design approach, generating eighteen innovative inhibitors targeting <i>Schistosoma mansoni</i> Dihydroorotate dehydrogenase (SmDHODH). A robust QSAR model yielded promising statistical parameters, and molecular docking of 31 known inhibitors lead to the identification of a lead candidate (Compound <b>21</b>) with favorable binding efficacy. Eighteen novel compounds were designed, showing improved binding affinities compared to both the lead compound and the standard drug, Praziquantel (PZQ). Molecular dynamics simulations and Density Functional Theory (DFT) affirmed the reactivity and stability of protein-ligand complexes under physiological conditions. These compounds exhibit strong inhibition of SmDHODH and meet drug-likeness criteria. Additionally, they demonstrate favorable pharmacokinetic properties, suggesting their potential effectiveness in treating schistosomiasis. Our study underscores the importance of understanding molecular properties for optimizing treatments against this neglected tropical disease.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s40203-024-00281-6.</p>","PeriodicalId":94038,"journal":{"name":"In silico pharmacology","volume":"12 2","pages":"113"},"PeriodicalIF":0.0,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11602894/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142775989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
