Ceftriaxone lead(II) complex -- DFT -- IR spectroscopy -- TGA -- Antibacterial screening
Аннотация: A Pb(II) complex with ceftriaxone (H2Ceftria) antibiotic was synthesized by reaction of ceftriaxone disodium salt (hemi)heptahydrate with lead nitrate in water–ethanol medium. The complex was characterized on the basis of complexometric titration, spectrophotometric and thermogravimetric analyses, capillary electrophoresis, IR, Raman and UV–vis spectroscopies, and density functional theory calculations. Pb(II) is five-coordinate with distorted square pyramidal geometry. The coordination of Ceftria2− to Pb(II) occurs through N and O of the triazine, lactam carbonyl, carboxylate, and amine groups. The antibacterial activity study showed that Klebsiella pneumoniae is resistant to [Pb(Ceftria)]·3H2O. The antibacterial activity of [Pb(Ceftria)]·3H2O against Staphylococcus aureus is reduced compared with ceftriaxone. In contrast, the antibacterial activity of [Pb(Ceftria)]·3H2O against Escherichia coli is 28% higher than that of ceftriaxone antibiotic.

Bacterial cellulose -- Composites -- Silver nanoparticles -- Antibiotics -- Properties -- Antibacterial activity
Аннотация: The present study describes production of bacterial cellulose composites with silver nanoparticles and antibiotics and compares their properties. Bacterial cellulose (BC) composites synthesized in the culture of the strain of acetic acid bacterium Komagataeibacter xylinus VKPM B-12068 with silver nanoparticles, BC/AgNps, were produced hydrothermally, under different AgNO3 concentrations (0.0001, 0.001, and 0.01 M) in the reaction medium. The presence of silver in the BC/AgNp composites was confirmed by elemental analysis conducted using scanning electron microscopy with a system of X-ray spectral analysis. Analysis showed that the average atomic number of silver particles in composite samples depended on the concentration of AgNO3: as AgNO3 concentration in the reaction solution was increased, silver content in the composites increased from 0.044 to 0.37 mg/cm2. BC composites with amikacin and ceftriaxone were prepared by immersing dry BC films in solutions containing different concentrations of the antibiotics. The surface structure and properties and physicochemical and mechanical characteristics of composites were investigated using SEM, DSC, X-ray analysis, the system for measuring water contact angles, and electromechanical tensile testing machine. The disk-diffusion method and the shake-flask culture method used in this study showed that all experimental composites had pronounced antibacterial activity against E. coli, Ps. eruginosa, K. pneumoniae, and St. aureus, and the BC/antibiotic composites were more active than BC/AgNp ones; S. aureus was the most susceptible to the effect of BC composites. No potential cytotoxicity was detected in any of the BC/AgNp composites in the NIH 3T3 mouse fibroblast cell culture, in contrast to the BC/antibiotic composites. These results suggest that BC composites constructed in the present study hold promise as dressings for managing wounds, including contaminated ones.

    Способ адресной доставки антибиотика в полости носа при раневых и воспалительных процессах (экспериментальное исследование) / К. Г. Добрецов [и др.] // Рос. ринология. - 2017. - Т. 25, № 4. - С. 3-8, DOI 10.17116/rosrino20172543-8. - Библиогр.: 10 . - ISSN 0869-5474
   Перевод заглавия: The method of the targeted delivery of an antibiotic into the nasal cavity for the treatment of wounds and inflammatory processes (an experimental study)
Кл.слова (ненормированные):
магнитные наночастицы -- магнитное поле -- антибиотики -- рана -- воспаление -- раневой процесс -- местное лечение -- полость носа -- ринохирургия -- magnetic nanoparticles -- magnetic field -- antibiotics -- wounds -- inflammation -- wound process -- topical treatment -- nasal cavity -- rhinosurgery
Аннотация: Экспериментальные исследования были выполнены на 30 крысах. Порошок амоксиклава (амоксициллин с клавулановой кислотой) растворяли в золе магнитных наночастиц ферригидрита. Полученным раствором смачивали марлевую салфетку и прикладывали к ране, после чего воздействовали внешним магнитным полем. При этом наблюдались выраженное снижение микробной контаминации раны и более быстрая эпителизация. Бактериологический контроль ран подтвердил высокую антибактериальную активность комплекса наночастица—ампициллин в отношении микроорганизмов рода Staphylococcus и сохранения нормальной микрофлоры эпидермиса животных. Эти данные были также подтверждены гистологически. Положительные результаты экспериментальных исследований по проникающей способности магнитных наночастиц в ткани носа, а также эффективность адресной доставки антибиотика при раневом и воспалительном процессах свидетельствуют о целесообразности дальнейших исследований и практическом применении их результатов в ринохирургии.
These experimental studies were performed on 30 rats. The amoxiclav powder was dissolved in the ashes of magnetic ferrihydrite nanoparticles. The resulting solution was moistened with a gauze cloth and applied to the wounds after which an external magnetic field was applied to the animals. The targeted administration of the drug resulted in the well apparent reduction of the microbial contamination of the wounds and their accelerated epithelization in comparison with those in the control animals. The results of the bacteriological control confirmed the high antibacterial activity of the nanoparticle-ampicillin complex with respect to the microorganisms of the genus Staphylococcus, in the absence of its detrimental effect on the state of the normal microflora in the epidermis of the experimental animals. These observations were also verified in the histological studies. The positive results of the present experimental studies are in excellent agreement with the data obtained in the earlier investigations on the penetration and distribution of magnetic nanoparticles in the nasal tissues and give evidence of the high effectiveness of the targeted delivery of antibiotics into the nasal cavity for the treatment of wounds and inflammatory processes. Moreover, they provide a basis for the further research and subsequent practical application of this method in rhinosurgery.

Heracleum dissectum -- Silver nano-antibiotics -- ESKAPE -- Antimicrobial-resistant -- Krasnoyarsk -- Siberia
Аннотация: The present study reports synthesis of silver nano-antibiotics from aqueous extract of H. dissectum. The nano-antibiotics were characterized using UV–visible spectra which displayed maximum absorbance at 430 nm. The role of phytocomponents as reducing agent and stabilization of silver nano-antibiotics was depicted with Fourier-transform infrared spectroscopy which revealed presence of hydroxyl and carboxyl groups associated with silver nano-antibiotics. The crystalline nature was studied with X-ray diffraction which showed Bragg’s intensities at 2θ angle which denoted (101), (111), (200), (220), (311) planes. The morphological characteristics were studied using Transmission Electron Microscopy to reveal the size ranging from 5 to 50 nm. The bactericidal activity of nano-antibiotics was studied via well diffusion and minimal inhibitory concentration assay against members of drug-resistant communities bearing resistant to more than ten standard antibiotics. Nano-antibiotics displayed highest activity against Ps. aeruginosa strain 55 and Methicillin-resistant Staphylococcus aureus with 16 mm zone of inhibition followed by Kl. pneumoniae strain 104 and E. coli strain 55. Moderate activity was observed against Ac. baumannii strains with 12 mm zone of inhibition. The obtained results envision the role of plant mediated nano-antibiotics as one of the best suited alternatives towards combating drug resistant pathogens.

    Synthesis and synergistic effect of antibacterial composites based on concentrated hydrosols of silver nanoparticles combined with cephalosporins antibiotics / S. A. Vorobyev, G. V. Novikova, A. V. Demina [et al.] // Inorg. Chem. Commun. - 2022. - Vol. 144. - Ст. 109862, DOI 10.1016/j.inoche.2022.109862. - Cited References: 49. - This research was supported by the Russian Science Foundation, project 18-73-00142 . - ISSN 1387-7003

Silver nanoparticles -- Concentrated hydrosols -- Cephalosporin antibiotics -- Antibacterial activity -- Minimal inhibitory concentration
Аннотация: Silver nanoparticles may be used as potential antimicrobial agents. Concentrated silver nanoparticles (AgNPs) were synthesised by the Carey Lee method. Then, antibiotics, such as disodium ceftriaxone, sodium cefotaxime, sodium cefazolin and sodium cefoperazone, were added to the AgNPs at the ratio of AgNPs:antibiotic = 5:1. The concentrated hydrosols were examined using UV–Vis, FTIR-spectroscopy, dynamic light scattering and transmission electron microscopy. The spectra plasmon resonance of silver nanoparticles and their combination with antibiotics had a single strong peak at 412–415 nm. The transmission electron microscopy micrographs showed different forms. The average size of AgNPs-antibiotic particles was smaller than that of AgNPs. The antibacterial activities of AgNPs, antibiotics and AgNPs-antibiotics were determined by the disk diffusion method against Staphylococcus aureus and Escherichia coli. The most significant enhancement of the antibacterial effect over the antibiotic was demonstrated by AgNPs-disodium ceftriaxone against E.coli. Also, the minimal inhibitory concentration (MIC) of the AgNPs-antibiotics was defined. All the AgNPs-antibiotic exhibited a synergistic enhancement by AgNPs and the antibiotic of antibacterial activity. A possible explanation of this phenomenon was proposed. Our results suggest that the synthesis of the concentrated hydrosol of the AgNPs-antibiotics is essential for studying similar nanosystems.
