No documented techniques for the simultaneous quantitation of Encorafenib and Cetuximab using LC-MS/MS was available, so a reliable, fast, and unique method was developed and validated. Method development involved optimizing chromatographic and mass spectrometric conditions to achieve high sensitivity and specificity. The method was validated per FDA guidelines, evaluating parameters such as linearity, precision, accuracy, recovery, and stability under various conditions. Mass ion pairs were tracked using multiple reaction monitoring (MRM) in positive polarity mode and the precursor to daughter ion transition <em>m</em>/<em>z</em> values for Encorafenib, Cetuximab(peptide), and Tofacitinib (internal reference) are 540.15 → 369.85, 643.34 → 653.31, and 313.17 → 221.05, respectively. The calibration curves demonstrated excellent linearity over 3.75–150 ng/mL ranges for Encorafenib and 0.25–10 ng/mL for Cetuximab. The MS<sup>2</sup> system offers a significant advantage with its ability to specifically target ions of interest. The technique was effectively employed to quantitate the levels of analytes, key pharmacokinetic parameters were assessed in rats following single-dose administration. Encorafenib exhibited a Cmax of 72.543 ng/mL, Tmax of 2 h, and T1/2 of 20 h, whereas Cetuximab showed a Cmax of 4.982 ng/mL, Tmax of 1 h, and T1/2 of 10 h. Stability studies confirmed the analytes' robustness under various conditions. These findings highlight the method's utility for accurate monitoring of pharmacokinetic parameters, essential for therapeutic drug monitoring in biological samples. It tracks drug levels drugs from administration to several hours post-dose at set intervals, enabling the evaluation of metabolism, excretion, and protein binding, which aid in the creation of treatment plans. It also facilitates routine monitoring of selected medications in clinical trials.</div></div>","PeriodicalId":348,"journal":{"name":"Journal of Chromatography B","volume":"1255 ","pages":"Article 124530"},"PeriodicalIF":2.8,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143471331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, 49 components were detected in the plasma of normally administered rats, including 29 prototype compounds and 20 metabolites; and 26 components were detected in the liver of normally administered rats, including 16 prototype compounds and 10 metabolites. 43 components were detected in the plasma of copper-laden administered rats, including 25 prototype compounds and 18 metabolites; and 23 components were detected in the liver of copper-laden administered rats, including 15 prototype compounds and 8 metabolites. A total of 73 GDL-related substances were detected in the urine of rats. The study results showed that the compositions in rats' plasma, liver, and urine were similar, mainly alkaloids and anthraquinones. The alkaloid components are mainly metabolized by phase I metabolism in vivo and the metabolic pathways are methylation, demethylation, etc. The anthraquinone components are mainly metabolized by phase II metabolism in vivo, and the metabolism modes are mainly glucuronidation and sulfation. The present study comprehensively analyses the metabolic properties of GDL and sets an essential basis for further investigations on the pharmacokinetics, in vivo bioactive components, and mechanism of action of GDL.</div></div>","PeriodicalId":348,"journal":{"name":"Journal of Chromatography B","volume":"1254 ","pages":"Article 124503"},"PeriodicalIF":2.8,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
