Neutrons in studies of phospholipid bilayers and bilayer–drug interaction. I. Basic principles and neutron diffraction

Pubblicato online: 30 Dec 2014
Pagine: 1 - 11

Astratto

Abstract

In our paper, we demonstrate several possibilities of using neutrons in pharmaceutical research with the help of examples of scientific results achieved at our University. In this first part, basic properties of neutrons and elementary principles of elastic scattering of thermal neutrons are described. Results of contrast variation neutron diffraction on oriented phospholipid bilayers with intercalated local anaesthetic or cholesterol demonstrate the potential of this method at determination of their position in bilayers. Diffraction experiments with alkan-1-ols located in the bilayers revealed their influence on bilayer thickness as a function of their alkyl chain length.

Abstract

In this paper, we demonstrate several possibilities of using neutron scattering in pharmaceutical research based on examples of scientific results achieved at our University. In this second part, elementary principles of small-angle neutron scattering and simple methods of scattering data evaluation are described. Results of scattering on bilayers in unilamellar liposomes with intercalated general anaesthetics, antimicrobials or cholesterol demonstrate the potential of this method at determination of structural properties of bilayers.

The variability of secondary metabolites in mentha × piperita cv . ‘perpeta’ during the development of inflorescence

Pubblicato online: 30 Dec 2014
Pagine: 21 - 25

Astratto

Abstract

Mentha × piperita (L.) Huds. of the family Lamiaceae is a very important species for commercial exploitation due to the high content of essential oil. Besides the essential oils, there are also other significant secondary metabolites in peppermint, especially flavonoids and hydroxycinnamic derivatives. In this study, we evaluate the variability of essential oil constituents and of phenolic compounds in the leaves of M. × piperita during the development of inflorescence. Similar studies, dealing with the variation of the essential oils and its composition, have been performed in the past, but no attention was paid to the variation of other secondary metabolites. We examined M. × piperita cv. ‘Perpeta’, the domestic cultivar. The plants were cultivated in the climatic conditions of south-west Slovakia. The contents of secondary metabolites were investigated in the week periods, from the beginning of inflorescence formation to the end of flowering. The yield and the quality of essential oil have been carried out by distillation and gas chromatography mass spectrometry (GC-MS). The phenolic substances were analysed using spectrophotometric methods according to European Pharmacopoeia. The highest contents of phenolic substances have been found in leaves of plants during the flowering phenophase, the same stage when essential oil of mint also achieves the highest quality.

DNA – DOPC – gemini surfactants complexes: effect of ionic strength

Pubblicato online: 30 Dec 2014
Pagine: 26 - 34

Astratto

Abstract

The effect of ionic strength on DNA condensation by cationic liposomes prepared as a mixture of ethane-1,2-diylbis(dodecyl-dimethylammonium bromide) (C2GS12) and dioleoylphosphatidylcholine (DOPC) was studied using fluorescence spectroscopy. The DNA condensation followed by changes in emission intensity of ethidium bromide shows a strong dependence on the ionic strength of the solution. At physiologically relevant ionic strength (0.15 mol/l NaCl), the amount of DNA condensed between lipid bilayers is approximately 40% lower compared to 0.005 mol/l NaCl. The structure of formed complexes was studied using small angle X-ray diffraction (SAXD). DNA–C2GS12–DOPC complexes form a condensed lamellar phase organisation, which is partially disrupted by the increase of ionic strength. Both the lamellar repeat distance and DNA–DNA distance show dependence on C2GS12/DOPC molar ratio, temperature and also on ionic strength. We found that the method of preparation significantly affects both the quality of organisation and the structural parameters of complexes as discussed in the paper.

Abstract

Medical devices (MD), together with pharmacotherapy are supportive treatment of many acute and chronic diseases. MD as a part of medical technologies lead to more effective treatment, faster patient recovery and a reduced risk of complications. Many MD are reimbursed from public health insurance funds entirely; for others, particularly advanced functional types of MD, there must be patient participation on price or they can buy them according own decision (direct sale). The target of this study is to analyze the data from paid databases of National Center for Health Information (NCHI) that collects the outputs of provided healthcare. The most recent data were from 1.1.2013 to 30.9.2013. According to NCHI, apart from community pharmacies, there are 226 registered establishments that sold MD until 30.9.2013. Their specialization included dispensing MD (n=163), dispensing orthopaedic devices (n=48) and dispensing audioprosthetic devices (n=15). In the observed period, average monthly spending on MD were 10.1 million packages and 14 million €. Average monthly spending on reimbursed MD were 8.8 million packages and 12.9 million €. The groups with the largest shares were MD for incontinence and urinary retention, 7.7 million packages (86.9%) and 3.9 million € (30.7%); plasters and bandaging materials, 0.5 million packages (6.0%) and 1.3 million € (10.1%); MD for ostomies, 0.4 million packages (4.5%) and 1 million € (8.0%); and the MD for diabetics group, 0.1 million packages (1.4%) and 1.6 million € (12.8%). Direct sales of MD per month on average reached 1.3 million packages and 1.1 million €. The groups with largest shares were MD for incontinence and urinary retention, 629,660 packages (50.3%) and 291,919 € (26.2%); plasters and bandaging materials, 388,111 packages (31.0%) and 227,119 € (20.4%); and MD for diabetics, 56,014 packages (4.5%) and 81,721 € (7.3%).

Synthesis and antimicrobial properties of camphorsulfonic acid derived imidazolium salts

Pubblicato online: 30 Dec 2014
Pagine: 42 - 48

Astratto

Abstract

A group of homochiral imidazolium salts bearing hydrophobic camphor derived moiety and ester or amide functional group were synthesized and characterized. The novel imidazolium bromides were tested as antimicrobial and antifungal agents and their minimal inhibitory concentration (MIC) was evaluated and compared to clinically used benzalkonium bromide (BAB) and carbethopendecinium bromide. The MIC values of amide derivatives 2a and 2b were slightly smaller than those for BAB, indicating their good activity. None of the prepared salts was more effective than carbethopendecinium bromide. The biocidal efficacy of amide derivatives was much higher compared to the ester analogues.

Study of physico-chemical properties of potential beta-adrenolytics

Pubblicato online: 30 Dec 2014
Pagine: 49 - 54

Astratto

Abstract

The aim of this paper is the study of physico-chemical properties of the chosen compounds, derivatives of 2-hydroxy-3-[2-(4-methoxyphenyl) ethylamino]propyl-4-[(alkoxycarbonyl)amino]benzoates and 2-hydroxy-3-[2-(2-methoxyphenyl)ethylamino]propyl-4-[(alkoxycarbonyl) amino]benzoates with potential ultra-short beta-adrenolytic activity. The studied compounds are different in the position of the substituent on the benzene ring in the side chain as well as in the aromatic ring in position 4 with alkyl- (methylto butyl-) carbamate. The physico-chemical characteristics, for example, lipophilicity, surface activity, adsorbability, acidobasic properties etc., are very important for the explanation of the relationship between structure and biological activity of the drug. These parameters serve as the base of quantitative structure-activity study. The goal of this work is to establish the spectral characteristics of studied compounds in UV-area, pKa values, the parameters of lipophilicity (the values of Rf and RM from thin layer chromatography, retention time t´R and capacity factor k´ from liquid chromatography and experimental partition coefficients log P´ values), surface tension, critical micelle concentrations, the adsorbability of compounds expressed by percent of adsorbed compound on active charcoal β% as well as by Freundlich adsorption isotherms. The obtained values are correlated with the parameters characterising the size of molecule, for example, the number of carbon atoms on carbamate functional group.

„Z”-scores of anthropometric and motor parameters of girls in aerobic gymnastics

Pubblicato online: 30 Dec 2014
Pagine: 55 - 58

Astratto

Abstract

This study presents the evaluation of chosen anthropometric and motor parameters in group of female junior competitors throughout the course of 2-year preparation of aerobic gymnastics by means of Z-scores. The observed group consisted of 12 girls (average age at the beginning of observance 14.08 ± 1.19 years). Evaluation of anthropometric (body height, body weight, body mass index, percentage of body fat, acting body weight) and motor parameters (sit-ups in 30 seconds and 60 seconds, pull-ups to bar, modified push-ups, standing long jump, backwards tandem walking, shuttle run 4×10 m, Jacík’s test) was carried out in standard conditions in nine girls at 3-month intervals. It has been confirmed that female probands with higher Z-score of motor parameters together with lower Z-score of anthropometric parameters achieved higher sport performance during the 2-year observance at competitions, with an exception of one such proband.
