This aspect is of great importance for their use as antineoplastic drugs. We synthesized ligands derived from short-chain amino acids and from salicylaldehyde. The prepared ligands of the type of reduced Schiff bases were subsequently used for the preparation of copper(II) complexes. The aim of the study was in vitro testing of copper(II) complexes, where it was confirmed that they are capable of cleaving DNA. Their cytotoxic activity was also confirmed by the resazurin redox method on Saccharomyces cerevisiae based on preserved healthy mitochondrial function.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2024-00032024-03-28T00:00:00.000+00:00Medicinal Mushrooms Cordyceps as a New Source of Bioactive Compounds and Their Complexation With Silver Ionshttps://sciendo.com/article/10.2478/afpuc-2024-0001<abstract> <title style='display:none'>Abstract</title> <p>Mushrooms from the genus <italic>Cordyceps</italic> are characterized by a wide range of biological effects due to the diverse amount of substances contained in them and are an important source of bioactive compounds. In China, mushrooms of the genus <italic>Cordyceps</italic> have been used as a medicinal preparation of traditional Chinese medicine for centuries. So far, a considerable number of studies have been conducted that focused on analyzing the effects of <italic>Cordyceps</italic>, which include their antioxidant, antibacterial, immunomodulatory, antidiabetic, antitumor, and many other effects. The ability of fungi to form complexes with various metals is also interesting. It is believed that polysaccharides are the main component of the extracts involved in the complexation with metals, after which their biological effects are improved and deepened. The work deals with the comparison of the antioxidant and antibacterial effects of <italic>Cordyceps</italic> extracts with extracts of this mushroom enriched with silver ions. Based on scientific studies, it is assumed that there is a complexation between the chemical compounds of the extracts and silver.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2024-00012024-03-18T00:00:00.000+00:00Aminopeptidase N as a potential drug targethttps://sciendo.com/article/10.2478/afpuc-2024-0002<abstract> <title style='display:none'>Abstract</title> <p>Aminopeptidase N (APN) is a broad specificity zinc metallopeptidase with many functions that do not always depend on its enzymatic activity. Among others, it is involved in tumor angiogenesis and metastasizing and also serves as a cellular receptor of some coronaviruses. Some APN inhibitors, such as bestatin or tosedostat, were used or tested as anticancer drugs in the past. Within the past two decades, we have prepared several series of potential APN inhibitors. Some of them reached interesting values of inhibitory activity and were also successfully tested for antiproliferation activity in cancer cell lines. We also performed some QSAR studies with APN inhibitors prepared by us and other authors.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2024-00022024-03-18T00:00:00.000+00:00Book of Abstracts 51st Conference Synthesis and Analysis of Drugs (SAD 2023) Oral Presentationshttps://sciendo.com/article/10.2478/afpuc-2023-0023ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2023-00232024-02-18T00:00:00.000+00:00Book of Abstracts 51 Conference Synthesis and Analysis of Drugs (SAD 2023) Poster Sessionhttps://sciendo.com/article/10.2478/afpuc-2023-0022ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2023-00222024-02-18T00:00:00.000+00:00Rosmarinic Acid in Underground Parts of Different Specieshttps://sciendo.com/article/10.2478/afpuc-2023-0006<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Mints (<italic>Mentha</italic> L., Lamiaceae) are medicinal plants frequently used in pharmacy, cosmetics, and food industry.

Owing to the energizing effects, it is mostly used in soft drinks and supplements for athletes. Regular intake of soft drinks may lead to an overdose of caffeine, taurine, and guarana and loss of bone mass, overweight, hypertension, and in older age, osteoporosis and cardiovascular diseases. Therefore, it is essential to control the maximum amount of taurine consumed by humans in the food and beverages. Here, a fast, simple, accurate, and robust method based on ultrahigh-performance liquid chromatography hyphenated with mass spectrometry (UHPLC-MS) was successfully applied for the determination of taurine in selected soft drinks sold in Slovakia. The method was characterized by coefficient of determination higher than 0.99, and the predicted value of the limit of detection was 4.29 μmol/L. The analyzed levels of taurine in selected commercial drinks ranged from 2.8 to 3.78 mg/mL. The concentration in one brand of the investigated drinks was found to be extremely low (about 70%) compared to the declared content by the manufacturer.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2023-00102023-08-31T00:00:00.000+00:00A Randomized, Two-Treatments, Two-Periods, Crossover, Open label, Laboratory-Blind, Single Dose Bioequivalence Study between Vildagliptin/Metformin 50 mg/1000 mg Film Coated Tablets (Sensityn) and Galvusmet 50 mg/1000 mg Film Coated Tablets in healthy adults under fed conditionshttps://sciendo.com/article/10.2478/afpuc-2023-0019<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Aim</title> <p>Vildagliptin/metformin 50 mg/1000 mg film coated tablets (Sensityn<sup>®</sup>) is being developed for the treatment of type 2 diabetes mellitus.

The ion channel activity was modulated by TMEM16A-nonselective (benzbromarone) and TMEM16A-selective blockers (CaCCinh-A01). <italic>In vivo</italic> airway reactivity, induced by histamine and methacholine, was expressed as specific airway resistance (sRaw) values. The number of citric acid-induced coughs was counted using a double-chambered body plethysmograph, and the frequency of ciliary beating (CBF) was assessed <italic>in vitro</italic> by brushing method.

This work is specifically focused on the formulation of microforms and multiple unit dosage forms with the mentioned resistant features. We prepared microcapsules based on sodium alginate by Ca<sup>2+</sup>-induced gelation, containing caffeine as a model drug. The prepared microcapsules were dried either by hot air or freeze-dried and the resistance in an alcoholic environment and the resistance against mechanical stress were observed. Subsequently, swelling studies were conducted to predict the behavior of prepared microcapsules during dissolution testing. Differences in the behavior of microcapsules during dissolution testing were strongly related to the different abilities of Ca<sup>2+</sup>-alginate microcapsules to swell in an acidic and alkaline environment. Alginate microcapsules exhibited gastro-resistant properties due to excellent swelling in an alkaline environment and poor swelling in a gastric environment. The addition of ethanol did not influence the swelling behavior of alginate microcapsules in the gastric fluid; rather, it showed the opposite effect, where swelling was slightly suppressed. Therefore, we conclude that alginate microcapsules are alcohol resistant. Also, they showed high mechanical strength, and therefore, grinding the microcapsules into a powder was impossible.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2023-00202023-09-15T00:00:00.000+00:00Synthesis, antioxidant activity, and HPLC enantioseparation of aryloxyaminopropanols derived from naphthalen-2-olhttps://sciendo.com/article/10.2478/afpuc-2023-0015<abstract> <title style='display:none'>Abstract</title> <p>The present work describes the synthesis, physico-chemical characteristics, antioxidative properties, and high-performance liquid chromatography (HPLC) enantioseparation of novel, potentially bioactive aryloxyaminopropanols – derivatives of naphthalen-2-ol modified in the basic part of their molecules. Reaction of naphthalene-2-ol with chloromethyloxirane leads to 2-[(naphthalen-2-yloxy)methyl]oxirane, which reacts in the next step with branched aliphatic amines (isopropylamine, <italic>tert</italic>-butylamine, and dimethylamine), aromatic amines (aniline, 3,4-dimethoxyphenylethylamine), and heterocyclic amines (pyrrolidine, imidazole, 2-methylimidazole, piperidine, morpholine, 4-methylpiperidine, or 2-methoxyphenylpiperidine). The target compounds were isolated in the form of free bases, as well as their salts with fumaric or hydrochloric acid. Their purity was established by thin-layer chromatography and their IR, UV, <sup>1</sup>H-NMR, and <sup>13</sup>C-NMR spectra were recorded. The antioxidant activities of prepared compounds were measured by the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) method and they were compared with the values for the corresponding salts.

The study aimed to examine the impact of the chosen technological procedure for the preparation of tablets containing rosehip powder on the amount of L-ascorbic acid in the final pharmaceutical form. Drying of the plant drug was performed at room temperature to avoid possible thermal degradation of this heat-sensitive compound. Similarly, drying of the granules after wet granulation in the oven was replaced by natural drying at room temperature. The composition of two types of prepared granule formulations differed in the filler – lactose (LAC) or microcrystalline cellulose (MCC). Apart from the disintegration test, they meet the technological requirements for granules or tablets. Lactose was confirmed as a more suitable filler, which despite the unsuccessful disintegration of the granules, ensures the disintegration of tablets within 15 minutes even without the addition of a special excipient acting as a disintegrant. The content of L-ascorbic acid detected using isotachophoresis – capillary zone electrophoresis was 87.16 ± 5.06 µg in LAC tablets and 63.33 ± 2.83 µg in MCC tablets.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2023-00612023-09-07T00:00:00.000+00:00Spheroids as 3D Cell Models for Testing of Drugshttps://sciendo.com/article/10.2478/afpuc-2023-0008<abstract> <title style='display:none'>Abstract</title> <p>Cell lines are an important tool for scientific research and clinical and pharmaceutical applications.

The study aimed to formulate the GL granules as a semi-product for the compression of tablets and evaluate the influence of the substitution of sucrose laurate (Ryoto<sup>®</sup>) with sucrose ester (Sisterna<sup>®</sup>) in the composition of the granules and the effect of granule size on the quality of the compressed tablets. Four types of granules, varying in grain size and the type of additional surfactant, were prepared by melt granulation. The traditional pharmacopoeia tests were used to assess tablets’ quality. The granule size significantly affected all evaluated parameters: hardness, uniformity of mass, friability, and disintegration. The replacement of sucrose laurate with sucrose ester caused a slight decrease in tablet strength and a shortening of disintegration. However, it did not significantly impact friability and uniformity of mass. For this reason, the excipient, sucrose ester, can be evaluated as an adequate replacement in the composition of GL tablets.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/afpuc-2023-00072023-08-24T00:00:00.000+00:00en-us-1
