These data sets are massive, sparse, and ever-evolving. Quantitative structure-activity relationship (QSAR) models, which predict biochemical activities from compound structures, face challenges in integrating the evolving experimental data agilely as studies progress. We developed QSAR-Complete (QComp), an imputation framework, to address these challenges. While QSAR models are updated at a slow pace through extensive retraining on enlarging data sets, QComp leverages existing QSAR models to immediately exploit new experimental data and improves the imputation of missing data. We demonstrate that the improvement is robust and substantial for imputing in vivo assays with only in vitro experimental data. Additionally, QComp assists in finding the optimal sequence of experiments by quantifying the reduction in statistical uncertainty for specific end points, aiding in rational decision-making throughout the drug discovery process.","PeriodicalId":44,"journal":{"name":"Journal of Chemical Information and Modeling ","volume":"27 1","pages":""},"PeriodicalIF":5.6,"publicationDate":"2025-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144720043","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}

Ligand-based virtual screening was performed in the Molport database (∼4.79 million compounds), and after applying physicochemical filters, 313 molecules with characteristics such as hydroxychloroquine were obtained. After obtaining bioactive conformations, the molecular structures were subjected to the study of pharmacokinetic predictions, in which 106 molecules presented properties for oral bioavailability, penetration of the BBB, PPB, and solubility (average). The toxicological property predictions proved plausible for the molecules, as they did not present warnings of hepatotoxicity, mutagenicity, potential risk of carcinogenicity, and LC50 and LD50 values higher than the controls. Subsequently, 81 structures were subjected to a molecular docking study of ACE2 receptor/Spike and Mpro. In the ACE2 receptor, four (4) ligands showed high binding affinity value, in which the molecule MolPort-010-778-422 had the best ΔG value of -9.414 kcal/mol, followed by MolPort-009-093-282 with ΔG = -8.978 kcal/mol. In the Mpro receptor, four (4) ligands showed high binding affinity values compared to control 11b, with emphasis on molecule MolPort-005-766-143 with ΔG = -8.829 kcal/mol, followed by molecule MolPort-046-186-743.

However, predicting EPOC results using novel catalytic materials under diverse conditions remains challenging. This study introduces a machine learning framework to predict electrochemical promotion behavior and the rate enhancement ratios (ρ), i.e., ratio between promoted and unpromoted reaction rate, based on the selected catalyst, reaction, and electrochemical condition descriptors. Several classification and regression models were trained and tested using a data set compiled from previous studies. The best-performing random forest (RF) and extreme gradient boosting (XGB) models were validated with new experimental data collected from systems employing lithium lanthanum titanate (LLTO) solid electrolyte and Pt-ZnO catalysts, achieving an R2 of 0.97 and a mean squared error (MSE) of 0.01. This data-driven approach is interpretable, generalizable to other catalytic systems, and provides a powerful tool for advancing the development of catalytic materials for EPOC in RWGS reactions.","PeriodicalId":44,"journal":{"name":"Journal of Chemical Information and Modeling ","volume":"25 1","pages":""},"PeriodicalIF":5.6,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701376","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}
