We found testosterone-S, epitestosterone-S, and DHEA-S to be selectively transported by BCRP and/or MRP4, whereas all studied androgen sulfates were substrates of MRP3, OATP1B1, OATP1B3, and OATP2B1. MRP2 did not transport any of the studied compounds. Evaluation of transport kinetics revealed MRP4 to interact with its substrates at high to moderate affinity, whereas the observed affinities towards MRP3, BCRP, and OATPs were mostly moderate. These results help to build a better mechanistic understanding of the disposition of androgen sulfates in the human body. Additionally, this data may be used to assess the feasibility of androgen sulfates as additional biomarkers in doping detection.</p>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":" ","pages":"103705"},"PeriodicalIF":3.7,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143492497","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}

This study aimed to explore the opinions of formulation experts regarding stress evaluation in clinical settings. Thematic analysis of the interviews revealed four key themes: The human factor in clinical sites, clinical sites as data providers, potential complexities in conducting tests within a clinical setting, and challenges associated with product-specific methods, equipment and devices. This study also suggests tools for setting up clinical test beds that can help the pharmaceutical industry improve stress evaluation and understand clinical product handling.

Protein particle formation during peristaltic pumping is described primarily as a surface-driven mechanism. Therefore, the effect of the anions was hypothesised to affect the particle formation with the smallest amount of protein adsorbing and the least particles formed in the presence of SCN<sup>-</sup>, followed by the highest in SO<sub>4</sub><sup>2-</sup>. The alternative hypothesis was that most protein particles would be formed in SCN<sup>-</sup> due to the lower intrinsic stability of Antibody A. On the other hand, if none of the factors dominates the particle formation, it would not necessarily follow the Hofmeister series linearly. This was shown to be the case as significantly more particles were formed in the presence of NaCl, which could be explained by the interplay of the protein's intrinsic, colloidal, and interfacial stability.

The results indicated that the concentration of CTAB dictated the hydrodynamic shape and size of SANPs. While both the micellized (> CMC) and monomeric forms (< CMC) of CTAB resulted in the formation of negatively charged near spherical particles, the SANPs containing micellized form of CTAB exhibited smaller and more compact hydrodynamic structure compared to those containing monomeric form of CTAB. The cytotoxicity studies involving cancerous cell lines (A549 and L132) indicated that the anticancer activity of CTAB was retained in the SANPs. Subsequently, encapsulation of doxorubicin (DOX), a potent anticancer drug in to SANPs enhanced the efficacy of the overall nano-formulation for effectively killing A549 and L132 cells. Additionally, the DOX loaded SANPs also exhibited the sustained and pH dependent drug release under reservoir-sink model.

Results showed that nanocellulose is inferior to MCC when used as a conventional filler. This is due to the difficulty in deaggregating and dispersing aggregates of nanocellulose using a typical dry blending process. To improve its effectiveness, nanocellulose prepared as a suspension was blended or “co-processed” with APAP using a twin-screw process. Microscopy images show that the twin-screw process coats the APAP with nanocellulose. The tabletability of APAP was significantly improved by low concentrations of nanocellulose up to 1.10% w/w.

Possible origins of the second-order process are discussed within the framework of small-molecule drug dissolution, after first probing the general utility of the higher-order rate term in more precisely fitting typical dissolution transients (for ibuprofen and ketoconazole) taken from the referenced work. Lastly, molecular dynamics (MD) simulations are performed using the prototypical drug, bupivacaine, that is shown to dimerize in aqueous solution under acidic conditions. Our findings point us to conclude that the Polli mechanism best describes cases where the drug forms dimers in solution at a rate comparable to that with which it dissolves (per the N-W mechanism), given non-sink conditions.
