We hypothesized that these two natural compounds could significantly affect the metabolism of abemaciclib by inhibiting the activity of the CYP3A4 enzyme, thus potentially increasing its concentration in the body. <em>In vitro</em>, rat liver microsomes (RLM) and human liver microsomes (HLM) were employed to explore the inhibitory effects and mechanisms of baicalein and fangchinoline on abemaciclib. <em>In vivo</em>, twelve healthy male Sprague-Dawley (SD) rats were randomly assigned to three groups: Group A (control group), Group B (baicalein), and Group C (fangchinoline). The concentrations of abemaciclib and its metabolite N-desethylabemaciclib (M2) were evaluated using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Finally, molecular docking method was employed to understand the interaction between abemaciclib and baicalein. It was indicated by the <em>in vitro</em> findings that both baicalein and fangchinoline inhibited abemaciclib metabolism in RLM through a mixed mechanism of competitive and non-competitive inhibition pathway. In HLM, baicalein inhibited abemaciclib metabolism by employing a hybrid mechanism of uncompetitive and non-competitive inhibition, while fangchinoline exhibited its inhibition in a competitive manner. <em>In vivo</em>, pharmacokinetic experiments revealed significant increases for AUC_(0-t) and AUC_(0-∞) of abemaciclib in Group B and Group C when compared to Group A, while the plasma clearance (CLz/F) of abemaciclib exhibited significant reductions. Moreover, molecular docking studies showed that both abemaciclib and baicalein docked to the active pocket of CYP3A4. This study demonstrated that the co-administration of baicalein or fangchinoline significantly affected the metabolism of abemaciclib, providing valuable insights for its clinical application.</div></div>","PeriodicalId":249,"journal":{"name":"Arabian Journal of Chemistry","volume":"18 1","pages":"Article 106073"},"PeriodicalIF":5.3,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142721476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While conventional methods hold their ground, the rise of chemical EOR, especially utilizing nanofluids, stands out due to its economic viability, enhanced recovery efficiency, and adaptability. The allure of nanofluid-enhanced oil recovery (N-EOR) has grown amongst researchers, albeit with underlying mechanisms that still harbor inconsistencies and ambiguities. This review meticulously examines the micro-mechanics of nanofluid interactions with heavy oil molecules, particles, and surfaces, the methodologies underpinning nanofluid-assisted EOR, multiphase displacement within pores and cores, and the fluid–solid coupling during such flows. Key findings show that nanofluids alter mineral wettability, adjust oil/water interfacial tension, shift structural disjoining pressure, and curtail viscosity. The prowess of N-EOR largely hinges on nanoparticle adsorption. Their affinity for mineral surfaces induces a shift towards water-wet states, while their interplay at oil/water boundaries can tweak interfacial tensions, fostering emulsification. One standout revelation is the adsorption of asphaltenes on nanoparticles, which mitigates asphaltene concentrations in heavy oil, thereby diminishing viscosity and amplifying oil extraction. Contrary to previous studies that merely spotlighted outcomes, our review delves deep into the complexities of nanoparticle adsorption, spotlighting the harmonious interplay between nanoparticle adsorption features and N-EOR operations. We unravel the intricacies of nanofluid behaviors during multiphase core displacement and provide a detailed overview of pertinent simulations. To encapsulate, this study demystifies potential N-EOR techniques and charts fresh research trajectories. Our revelations aim to enrich the comprehension of N-EOR phenomena, accentuating the pivotal role of nanofluids in multiphase core transitions and computational simulations. Furthermore, we highlight lingering challenges, directing the scientific community towards continued nanoparticle innovations and exploration. The novelty of this study is as follows: Nanofluids are mainly used in the third oil recovery process, and are not used in the first and second oil recovery processes. In addition, during the third oil recovery, some nanofluids may remain in the mine due to the sedimentation characteristics of nanomaterials. Currently, we are also committed to developing new processes to reduce the deposition of nanomaterials in the mine. At present, it is not clear how nanofluids enhance the oil recovery mechanism, and the oil recovery mechanism is relatively chaotic.
