PURPOSE The aim of the study was to analyze the effects of two-month supplementation with chokeberry preparation on the activity of angiotensin I-converting enzyme (ACE) in patients with metabolic syndrome (MS). During the in vitro stage of the study, we determined the concentration of chokeberry extract, which inhibited the activity of ACE by 50% (IC50).(More)
PURPOSE A diet rich in berries is believed to play a distinct role in the prevention of metabolic diseases associated with obesity. So far, there have been no published clinical observations evaluating the influence of Aronia melanocarpa on hemostasis. The aim of our study was to investigate the effects of A. melanocarpa extract (AM) supplementation on(More)
High-throughput screening (HTS) is one of the newest techniques used in drug design and may be applied in biological and chemical sciences. This method, due to utilization of robots, detectors and software that regulate the whole process, enables a series of analyses of chemical compounds to be conducted in a short time and the affinity of biological(More)
UNLABELLED The last decade has brought many examples of utilization of dendrimers as drug delivery systems; however, their possible application is limited because of inherent toxicity associated with them. This study discusses the influence of G1-G4 PAMAM-NH2 dendrimers on the process of hemostasis and integrity of endothelial monolayer. The global assay of(More)
Metformin, a synthetic biguanide, is currently one of the most frequently recommended medications for type 2 diabetes treatment around the world. In this review, we present the latest discoveries in the pharmacokinetics of metformin, especially the role of transporters (e.g. Organic Cation Transporters OCTs, Multidrug and Toxin Extrusion transporters MATE)(More)
Dementia affects about 8% of people age 65 years and older. Identification of dementia is particularly difficult in its early phases when family members and physicians often incorrectly attribute the patient's symptoms to normal aging. The most frequently occurring ailments that are connected with neurodegeneration are: Alzheimer's disease, Parkinson's(More)
Combinations of nitrilotriacetic acid (NTA) derivatives with technetium 99mTc are known as convenient contrasting compounds used in nuclear medicine. Because of low resolution of this method, as well as necessity for using radioactive substances we have suggested new combinations of NTA aromatic derivatives with Gd(III). The aim of the undertaken study was(More)
Obtained benzimidazole derivatives, our next synthesized heterocyclic compounds, belong to a new group of chemical bondings with potential anticancer properties (Błaszczak-Świątkiewicz & Mikiciuk-Olasik, 2006, J Liguid Chrom Rel Tech 29: 2367-2385; Błaszczak-Świątkiewicz & Mikiciuk-Olasik, 2008, Wiad Chem 62: 11-12, in Polish; Błaszczak-Świątkiewicz &(More)
Copper is one of the most interesting elements for various biomedical applications. Copper compounds show vast array of biological actions, including anti-inflammatory, anti-proliferative, biocidal and other. It also offers a selection of radioisotopes, suitable for nuclear imaging and radiotherapy. Quick progress in nanotechnology opened new possibilities(More)
In the present study we describe the synthesis and biological assessment of new tacrine analogs in the course of inhibition of acetylcholinesterase. The obtained molecules were synthesized in a condensation reaction between activated 6-BOC-hydrazinopyridine-3-carboxylic acid and 8-aminoalkyl derivatives of 2,3-dihydro-1H-cyclopenta[b]quinoline.
