Initially, a comprehensive risk assessment was conducted using an Ishikawa (fish-bone) diagram. Following this, an Analytical Target Profile (ATP) was established, with desired specification and Critical Analytical Attributes (CAAs) were identified to fulfil these requirements. Additionally, Critical Material Attributes (CMAs) and Critical Process Attributes (CPPs) were chosen, as they can influence the CAAs. Subsequently, a three-level factorial design was utilized to optimize the primary contributing factors both numerically and graphically. The validation study was performed according to International Council for Harmonisation (ICH) guidelines and forced degradation studies were performed under various stress conditions. Optimal chromatographic separation was done using a mobile phase comprising acetonitrile and water with 0.3% formic acid in both phases at a ratio of 80:20% v/v, with 1.2 mL/min flow rate and UV detection at 248 nm. The developed method exhibited high sensitivity and specificity, with a linear range of 10–70 µg/mL and a correlation coefficient (R2) of 0.9999. It demonstrated accuracy with % recovery ranging from 98–100% and the detection and quantification limits of 0.2443 µg/mL and 0.7403 µg/mL, respectively. The forced degradation studies indicated that the drug is vulnerable to all stress conditions. Overall, the developed method proves to be suitable for estimation of Eltrombopag olamine in its marketed formulation, with potential applicability for analysing it in other dosage form and various biological samples available.</p></div>","PeriodicalId":518,"journal":{"name":"Chromatographia","volume":"87 10","pages":"635 - 648"},"PeriodicalIF":1.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the F&amp;F industry relies heavily on experimental approaches without considering the potential consequences of altering the features that contribute to the fragrance of the compound. In silico approaches have great potential to identify the necessary features for creating novel F&amp;F compounds. In the present study, Quantitative Structure–Property Relationship (QSPR) models were developed using 1208 compounds and simple 2D descriptors, focusing on the RI (retention index) as the endpoint to predict the olfactory properties of molecules. Feature selection was initially carried out by multi-layered stepwise regression followed by feature thinning using the Genetic Algorithm (GA) and optimal feature combination selection using the BSS (best subset selection) method. Final models were developed using the Partial Least Squares (PLS) method. Additionally, internal and external validation of the models was performed using different validation metrics suggesting that the developed models are reliable, predictive, reproducible, and robust. To enhance the external prediction of the developed models, an Intelligent Consensus Prediction (ICP) method was employed and <b>CM3</b> (consensus model 3) (best selection of predictions (compound-wise) from individual models) was found to provide the best predictivity. The modeling descriptors suggested that the hydrophobicity, high molecular weight, aromaticity, and presence of large-size fragments (high percentage of carbon) enhance the RI values. Conversely, polarity and hydrophilicity decrease the RI values. This study can be used to optimize the stationary phase according to the flavor and fragrance compounds to obtain the desired retention index (RI values).</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":518,"journal":{"name":"Chromatographia","volume":"87 9","pages":"581 - 595"},"PeriodicalIF":1.2,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141742708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
