The stability constants of the studied coordination entities were calculated potentiometrically. The logarithm values of the overall stability constants of the coordination entities were found to be [Ag-deoxy]+ = 3.07, [Ag-(deoxy)2]+ = 6.90, [Ag-ribo]+ = 3.00 and [Ag-(ribo)2]+ = 6.63. Based on the species distribution curves as a function of CL/CM, the percentage of each coordination entity formed in aqueous solution was estimated (12 % [Ag-deoxy]+; 36 % [Ag-(deoxy)2]+; 16 % [Ag-ribo]+; 26 % [Ag-(ribo)2]+). It was found that the ligands form coordination entities with Ag(I) ions with stoichiometric ratios M : L = 1 : 1 and 1 : 2. Such coordination entities may show potential antiviral, antibacterial, and antitumor properties, which warrants further in vitro and in vivo studies. They may also be of great interest for their application in nanobiotechnology.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45510200","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}

It was shown that in protein-restricted rats simvastatin stimulated liver BCKDH, whereas it exerted no effect on BCKDH in rats fed a standard diet. We hypothesized that combination of simvastatin and low-protein diet could have an impact on renal 2-OGDH. The purpose of the study was to determine the effect of combination of simvastatin and low-protein diet on renal 2-OGDH in rats. Simvastatin (80 mg/kg b.wt/day) or the vehicle (0.3% methylcellulose) were administered orally (for 14 days) to rats fed low-protein (8% protein) or standard (23% protein) diet. 2-OGDH activity, protein levels and mRNA levels for E1 and E2 subunits were determined. In addition, serum creatinine level was measured. Results: The combination of simvastatin and low-protein diet elicited the increase of renal 2-OGDH activity that corresponded to the increase of E1 protein, but not of E1 mRNA level. In contrast, simvastatin treatment did not affect 2-OGDH activity, nor protein and mRNA levels of E1 in rats fed standard diet. Serum creatinine levels were not changed upon simvastatin administration in any group. In conclusion, the results of present study indicate that combination of simvastatin and low-protein diet induces stimulation of renal 2-OGDH complex probably at post-transcriptional level.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47605321","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 long process of generic formulation development can be accelerated by using an inhaler with suitable fluid dynamics features. This paper presents a study of a newly patented single-dose Memmatec Mora® inhaler in two versions: with grid openings 1.0 (A) and 0.5 mm (B), using Seebri Breezhaler® as a reference product. The studies were conducted with inhalation powders containing 44μg glycopyrronium bromide placed in a capsule. The manuscript presents studies during the selection of a generic inhaler within the course of inhalation powder development by a pharmaceutical company. The fluid dynamics features of the inhalers and the dose delivered were determined. The aerodynamic particle size distribution (APSD) and the inhalable dose were tested using a cascade impactor. The delivery dose for the Breezhaler, Mora A and Mora B inhalers for a volumetric flow of 100 L×min-1 was 38.5, 40.5 40.3μg, respectively. Fine particle fraction of the inhalers tested was 22.3, 24.6 25.5μg, respectively. Results of the study indicate that increase of the glycopyrronium bromide inhalation dose can be achieved not only by changes in the manufacturing technology of inhalation powder, hard capsule technology or addition of best quality raw materials, but also by the use of a properly selected inhaler with specific fluid dynamics features.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47378679","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}

Appropriate analytical procedures are necessary to monitor, detect and quantify CBZ in pharmaceutical formulations and biological samples. The search for new methods for drug determination is one of the most important challenges of modern scientific research. It is important to study the chromatographic conditions of CBZ analysis, which is necessary for the further development of efficient drug determination methods. In this work, retention, peak symmetry, and system efficiency of CBZ on Polar RP and Phenyl-Hexyl stationary phases were investigated. Various mobile phases containing methanol (MeOH) and/or acetonitrile (ACN) as organic modifiers, acetate buffer, and the addition of diethylamine (DEA) were applied. Different chromatographic systems were compared to obtain satisfying retention, peak shape, and system efficiency. The most optimal chromatographic system with Polar RP column was applied for the determination of CBZ in pharmaceutical formulations, human serum, and saliva by the high-performance liquid chromatography with diode array detection (HPLC-DAD) method. Solid-phase extraction (SPE) method was applied for sample preparation prior to chromatographic analysis. The proposed method was validated for linearity, selectivity, precision, and accuracy. Confirmation of the presence of CBZ and its main metabolites in biological samples obtained from patients was performed using the ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43426622","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}

Exogenous factors affecting the process of skin aging, together with nutrition, are topics which currently draw considerable attention. Although it is difficult to accurately define what presents a healthy diet for maintenance of youthful skin, considering the evident lack of clinical data and studies in humans, there are numerous evidence suggesting that the food we eat affects our skin aging and its’ appearance. Well-documented is a fact that the modern diet is a large source of advanced glycation end products and reactive oxygen species – compounds formed during certain food preparation methods which accumulation is associated with different disease and recently, skin aging as well. This review gives the current state of knowledge related to the role which advanced glycation end products and reactive oxygen species, formed during the certain food preparation methods, have in the mechanisms of the premature/extrinsic skin aging. Additionally, it summarizes available information, in the form of recommendations for both the public and nutritional professionals who have an interest in this field, regarding food preparation methods and practices which prevent formation of aforementioned compounds in food and consequently could reduce the food contribution to premature skin aging.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42628221","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 presence of mutations in the fms-like tyrosine kinase 3 (FLT3) gene is found in approximately 30% of AML patients. Midostaurin, a first-generation multi-targeted tyrosine kinase inhibitor, is the first FLT3 inhibitor approved for the treatment of newly diagnosed AML patients with the FLT3 mutation in combination with standard induction and consolidation chemotherapy. However, as numerous clinical trials have shown, the list of indications for this drug is likely to be extended. Midostaurin can be administered orally, which improves the patient’s comfort during treatment. In general, it has a favourable safety profile, but interactions with other drugs, such as strong CYP3A4 inhibitors or inducers, which are often used in the concomitant therapy of AML patients, may lead to changes in midostaurin plasma concentrations. In consequence, such interactions may increase the toxicity of the treatment or reduce its therapeutic effect. The aim of this review is to summarise the current knowledge on midostaurin, i.e. its mechanisms of actions, dosage, adverse effects, mechanisms of resistance and limitations to its use. Due to the growing importance of the management of drug-drug interactions mediated via cytochrome CYP3A4, the main focus of this study is the pharmacokinetics of midostaurin and the variability of its plasma concentrations. The Authors emphasise therapeutic drug monitoring with midostaurin as a potential method of managing AML patients with FLT3 mutation.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41946910","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}
