Recent studies emphasize the impact of metabolites in the gut microbiome on T2DM pathogenesis. One such microbial metabolite, imidazole propionate (Imp) derived from histidine metabolism, is shown to interfere with insulin signalling and other key metabolic processes. The key enzyme urocanate reductase (UrdA) is involved in ImP production. Hence, we propose to develop a novel therapeutic vaccine against the gut microbe producing Imp based on UrdA as a target for treating T2DM using immunoinformatics approach. Antigenic, non-allergic, non-toxic, and immunogenic B cell and T cell potential epitopes were predicted using immunoinformatics servers and tools. These epitopes were adjoined using linker sequences, and to increase immunogenicity, adjuvants were added at the N-terminal end of the final vaccine construct. Further, to confirm the vaccine's safety, antigenic and non-allergic characteristics of the developed vaccine construct were assessed. The tertiary structure of the UrdA vaccine sequence was predicted using molecular modelling tools. A molecular docking study was utilized to understand the vaccine construct interaction with immune receptors, followed by molecular dynamics simulation and binding free energy calculations to assess stability of the complex. In silico cloning techniques were employed to evaluate the expression and translation effectiveness of the developed vaccine in pET vector.

Despite extensive research, effective treatments addressing the multifaceted pathophysiology of AD remain elusive. This study investigates the therapeutic potential of twenty-seven prolinamides (P1 - P27), with the focus on their interactions with key proteins implicated in AD pathogenesis. Four of the compounds, namely; 10-((4-nitrophenyl)prolyl)-10 H-phenothiazine (P14), 2-((4-nitrophenyl)prolyl)isoindoline (P19), 1-(4-formylphenyl)-<i>N</i>-(p-tolyl)pyrrolidine-2-carboxamide (P22), and <i>N</i>,1-bis(4-nitrophenyl)pyrrolidine-2-carboxamide (P27) showed promising potential as Alzheimer's drug. In-silico approaches including molecular docking, molecular dynamic (MD) simulation, post md study, physicochemical and drug-likeness parameters were employed to ascertain the potential of these compounds as inhibitors of certain proteins implicated in the pathophysiology of Alzheimer's disease. Molecular docking and dynamics simulations demonstrated that P14, P19, P22 and P27 exhibited promising binding affinities towards crucial AD-associated proteins, including Beta-Secretase 1 (BACE1), Butyrylcholinesterase (BuChE), and Tau-tubulin kinase 2 (TTBK2). Structural stability analyses revealed that prolinamides, particularly P22 and P27 for BACE1 and P14 and P19 for BuChE, exhibited greater stability than their reference ligands, indicated by lower RMSD, RoG, and RMSF values. For BuChE, Rivastigmine had a docking score of -7.0 kcal/mol, a binding free energy (ΔG<sub>bind</sub>) of -22.19 ± 2.44 kcal/mol, RMSD of 1.361 ± 0.162 Å, RMSF of 9.357 ± 3.212 Å, and RoG of 22.919 ± 0.064 Å, whereas P19 exhibited a superior docking score of -10.3 kcal/mol, a significantly better ΔG<sub>bind</sub> of -33.74 ± 2.84 kcal/mol, RMSD of 1.347 ± 0.132 Å, RMSF of 8.164 ± 2.748 Å, and RoG of 22.868 ± 0.070 Å. Physicochemical and pharmacokinetic assessments affirmed the drug-likeness and bioavailability of P19 notably capable of penetrating the blood-brain barrier. Compounds P19 and P22, emerged as multi-targeted ligands, offering the potential for simultaneous modulation of multiple AD-related pathways. These findings highlight the possibilities of these compounds to be explored as novel therapeutic agents for AD. They also highlight the need for further experimental validation to confirm their efficacy and safety profiles, advancing them toward clinical application in AD management.</p><p><strong>Graphical abstract: </strong></p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s40203-024-00250-z.</p>","PeriodicalId":94038,"journal":{"name":"In silico pharmacology","volume":"12 2","pages":"80"},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11365881/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142121435","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}

Molecular docking of small peptides against the target protein can play a crucial role in recognizing peptide binding sites and poses. The docking study was done using the HDOCK server and the visualization of the docked complex was done using Pymol and UCSF chimera. The molecular simulation study of three protein-peptide complexes were done which also validated the binding affinity of peptide with the proteins. The RMSD, RMSF and radius of gyration are also analyzed. The results indicate that H-FABP shows higher level of binding interaction with the peptide having bond length ranging from 2.3 to 3.4 Å. The screened peptide is suitable for H-FABP binding and can be used for prognosis purposes in the heart ischemic conditions.</p>","PeriodicalId":94038,"journal":{"name":"In silico pharmacology","volume":"12 2","pages":"76"},"PeriodicalIF":0.0,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11339228/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142057663","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}
