antibacterial activity

In the current study, ligands S2 donor atoms, sodium N-methyl-N-phenyldithiocarbamate [L1], and sodium N-ethyl-N-phenyldithiocarbamate [L2] are prepared from carbon disulfide with N-methyl aniline and N-ethyl aniline, respectively. Sn(II) and Sn(IV) ions complexes containing N-alkyl-N-Phenyl dithiocarbamateare prepared and characterized by CHNS elemental analysis, infrared spectroscopy (FT-IR), 1HNMR-spectroscopy, mass spectroscopy, UV-visible spectroscopy, magnetic susceptibility and conductivity measurements.

The possibility of using hydrogels based on copolymers of polyvinylpyrrolidone with 2 hydroxyethylmethacrylate to saturate them with plant extracts was established. Hydrogel materials were obtained with extracts of Calendula officinalis and Arnica montana. The sorption capacity of the hydrogels regarding the extract data was determined.

Hydroxyapatite nanoparticles were isolated from a biowaste, buffalo bone, via the thermal decomposition method. The resulting white powdered material was characterized by Fourier Transformed Infrared (FTIR) spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray (EDX) analysis. The FTIR spectra confirmed that a heat treatment of the bone powder at the temperature at or above 1223 K removed the organic moieties leading to the formation of a pure inorganic biomineral.

The possibility of using hydrogels,that are based on copolymers of polyvinylpyrrolidone with 2-hydroxyethylmethacrylate for saturation them with extracts of plants,was researched. Hydrogel materials with extracts of Calendula officinal is and Arnica montana were obtained. The sorption capacity of the hydrogels in relation to these extracts and the content of flavonoids in the extracts were determined  by using Ulab108UV.

The actual problem in medicine is a phenomenon of antibiotic resistance, therefore, it is expedient to develop and introduce new antibiotics or to improve the transport of already known antibiotics into the cell. PEGylating is the one of the most successful ways of improving of the delivery of therapeutic molecules to the cell, such as proteins, oligonucleotides and other biomolecules. Thus, it is promising to introduce PEG fragments into the structure of antibiotics with the preservation of their biological activity.

To study the action spectrum of S.purpurea, the analysis of the  literary sources was 

In order to explore the possibility of expanding the range of use of complex biologically active compounds of wild carrot an initial screening of phytochemical composition and antimicrobial activity of water and ethanol extract from seeds of wild carrot was conducted and computer screening of biological activity of active substances by program PASS was carried out. In the investigated extract chlorogenic, caffeic, rosemary acids, rutin, apigenin, luteolin, hyperoside were identified.
