The aim of the present study is to develop a convenient method for simultaneous estimation of Exemestane (EXE) and Everolimus (EVE) in bulk and in systemically designed tablet dosage form. Methanol was used as a solvent for developing linear curves and validated in terms of various parameters, such as selectivity, sensitivity, linearity, precision, accuracy, and robustness. Method validation observed that the proposed method is reliable and reproducible, meeting the regulatory requirements for pharmaceutical analysis with a relative standard deviation of <2%. The developed method was found to be sensitive and selective in simultaneous equation method. The unknown concentrations of EVE and EXE were found to be 10.431 and 10.232, respectively. The next step is to systematically design a tablet formulation for EXE and EVE containing β-cyclodextrin as a polymer. Microcrystalline cellulose (X1), sodium starch glycolate (X2), and beta-cyclodextrin (X3) are the critical variables and hardness (Y2) and friability (Y3) were selected as prime responses. Analysis of variance provides significance of the model, and the predicted batch gives a high desirability value of 0.862. In vitro dissolution profiles of optimized batch (OB1) were signified by high drug release profile as 89.47% and 96.00% for EVE and EXE in tablet formulation, as compared with pure API, respectively. This study signifies enhancement in biopharmaceutical attributes of EXE and EVE in tablet formulation and robust simultaneous estimation by the UV method. In a nutshell, this study provides the simultaneous estimation method in tablet dosage form, and further research is crucial for the advancement of pharmaceutical analysis and the formulation of effective medicines.</p>","PeriodicalId":8586,"journal":{"name":"Assay and drug development technologies","volume":"21 6","pages":"273-287"},"PeriodicalIF":1.8,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10358250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drug-target interactions, one of the LRIs, are important to understand the biological processes that further help in developing new and better therapeutic molecules. Biosensors based on these interactions give us an idea for the need of modification of existing drugs or to develop new drugs. Common approach to develop biosensors requires the labeling; however, label-free systems provide advantages in avoiding the chances of conformational changes, off-site labeling, and labeling-based hindrances, thus saving time and effort toward assay development. Preliminary drug screening assays are carried out in two-dimensional (2D) models, followed by animal models, which require huge capital investment to reach from bench-top to clinical trials, where only 21% of new compounds make way to phase-1 clinical trials. Three-dimensional culture or organoid culture or organ-on-chip technology has made way for predictive and complex <i>in vitro</i> approach that recapitulates human physiology and represents more similar <i>in vivo</i> behavior than 2D.

This study attempted to probe the impact of TWIST1 on CRC stemness and resistance to oxaliplatin and to uncover the underlying regulatory mechanism of TWIST1. mRNA expression data from The Cancer Genome Atlas-CRC were subjected to differential analysis. The target gene in the study was determined according to literature citation. ChIPBase was utilized to predict likely targets downstream of the target gene. Pearson was employed for correlation analysis. Quantitative real-time polymerase chain reaction was used to assess TWIST1 and microfibrillar-associated protein 2 (MFAP2) levels in CRC and normal cells. The cell viability was assayed through cell counting kit-8 and IC<sub>50</sub> value was calculated. Flow cytometry was applied to assay the cell apoptosis. Apoptosis assays were applied to evaluate cell apoptosis. CD44, CD133, SOX-2, ERCC1, GST-π, MRP, and P-gp protein expression levels were assayed by Western blot. The targeting relationship between TWIST1 and MFAP2 was ascertained through dual-luciferase and chromatin immunoprecipitation (ChIP). TWIST1 possessed high expression in CRC tissue and cells. TWIST1 knockdown strikingly promoted cell apoptosis and reduced cell stemness and cell resistance to oxaliplatin. Bioinformatics prediction suggested that MFAP2, which was overexpressed in CRC tissue and cells, was the target gene downstream of TWIST1. Dual-luciferase and ChIP assays validated that there was a targeting relationship between TWIST1 and MFAP2. The results of the rescue assay demonstrated that TWIST1 fostered CRC stemness and oxaliplatin resistance by activating MFAP2 expression. These outcomes implied that TWIST1 enhanced CRC stemness and oxaliplatin resistance by activating the transcription of MFAP2.
