Specifically, we focused on assessing the bioavailability and dose proportionality following oral administration.Blood samples were collected via a jugular vein catheter, and plasma samples were analysed using a validated HPLC-MS/MS method. The calculation of pharmacokinetic parameters was performed by both non-compartmental and compartmental approaches. The proposed dosage form for intravenous administration was a multicomponent mixture containing N-methyl-2-pyrrolidone.Concentration of IBP in the body after intravenous administration decreased over time, exhibiting bi-exponential decay kinetics. IBP reached peak concentrations immediately and was rapidly distributed into the peripheral compartment after intravenous administration. The systemic exposure after oral administration was proportional to the dose. The calculated absolute oral bioavailability of IBP was no more than 20%.The value of the average half-life of IBP after intravenous administration exceeded similar values after oral administration by 1.5-1.6 times.","PeriodicalId":23812,"journal":{"name":"Xenobiotica","volume":" ","pages":"1-10"},"PeriodicalIF":1.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143442192","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}

The goal of current investigation was to develop eugenol fortified fisetin nano-invasomes. Fisetin loaded invasomes were prepared using thin film hydration procedure and evaluated for various parameters.

Prepared optimized fisetin invasomes formulation (F5) demonstrated vesicles size, PDI, zeta potential and entrapment efficiency of 153.85 ± 14.32 nm, 0.208 ± 0.042, -12.67 ± 1.08 mV and 72.10 ± 6.36%. The TEM image indicated that the prepared invasomes vesicles are intact, spherical and found in the range of nanosized scale. Prepared fisetin invasomes gel showed better spreadability and in vitro fisetin released in contrast to fisetin control gel. Substantial improvement in the DPPH radical scavenging activity of fisetin invasomes gel 44.70% (3.1 µM) and 83.94% (50 µM), was noted as compared to the control gel at 39.47% (3.1 µM) and 79.10% at (50 µM). The prepared fisetin invasomes gel formulation was found stable at 4 °C.3.

Utilising D. melanogaster's genetic tools and short life cycles, researchers can discover new therapeutics and study their mechanisms.This twofold exploration not only advances our understanding of Nrf2 in human health but also provides insights into pest control strategies through enhanced insect resistance mechanisms.

Adverse events (AEs) of DTG treatment, including headache, anxiety, depression, insomnia, and abnormal dreams, are influenced by sex, body weight, age, and serum bilirubin levels. DTG is mainly metabolised by members of the uridine diphosphate glucuronosyltransferase 1A subfamilies (UGT1As), especially UGT1A1.Some studies suggest a relationship between UGT1A1 variants and AEs. The aim of this study was to identify UGT1A isoforms that exhibit DTG glucuronidation activity and determine the relationship between UGT1A variants and DTG glucuronidation in vitro.UGT1A1, UGT1A3, UGT1A9, and UGT1A10 exhibited DTG glucuronidation activity, of which UGT1A1 was the most active. Furthermore, variants of these isoforms showed decreased DTG glucuronidation activity. The different variants of UGT1As, such as UGT1A1.6, UGT1A1.7, UGT1A1.35, UGT1A1.63, UGT1A3.5, UGT1A9.2, UGT1A10M59I, and UGT1A10T202I, showed reduced glucuronidation activity towards DTG in comparison with the wild-type UGT1As.This study elucidates the relationship between UGT1A variants and the levels of glucuronidation associated with each variant.Checking for UGT1As may be helpful in predicting potential toxicities and adverse effects related to DTG treatment.","PeriodicalId":23812,"journal":{"name":"Xenobiotica","volume":" ","pages":"1-8"},"PeriodicalIF":1.3,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143012803","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}

While pirfenidone has demonstrated efficacy in slowing the progression of IPF, its use is associated with several challenges and unresolved issues that impact patient outcomes. Pirfenidone administration can result in gastrointestinal side effects, photosensitivity reactions, and significant drug interactions, particularly in patients with hepatic impairment. For those who experience intolerable side effects, dose reductions or temporary discontinuations are frequently employed. However, there is limited data on the efficacy of reduced doses, creating uncertainty about the balance between tolerability and therapeutic benefit.The aim of this study is to evaluate the currently proposed dosage adjustments and to develop new dosage regimens tailored to the needs of patients. Simulations were conducted to explore pirfenidone pharmacokinetics under various challenging conditions, including dose titration, withdrawal, retitration, moderate and severe hepatic impairment, co-administration of moderate (e.g. omeprazole) and strong (e.g. smoking) inducers of the CYP1A2 enzyme, gastrointestinal adverse events, and photosensitivity reactions.Simulations led to specific recommendations for physicians regarding dosage regimens in each condition.
