“…Past three decades, attention in the chemistry of first row transition metal Schiff base chelates is very high because of their essential it in the field of catalysis like hydroformylation, carbonylation, oxidation, reduction, hydrolysis and epoxidation [1][2][3][4][5][6][7]. Schiff base complexes are also noted for their significant antifungal and antibacterial activities.…”

New cationic 14-membered macrocyclic Schiff base metal complexes have been synthesized by condensation of benzalidene-curcuminyl-4-iminoantipyrine and 2,6-diaminopyridine. Structural characterization of the compounds was done using elemental analysis, molar conductivity, magnetic susceptibility, Mass, SEM, XRD, 1 H NMR, UV-visible, IR and EPR spectra. X-ray diffraction patterns suggested that the size of Schiff base is reduced due to chelation by the metal ion. Different morphologies of synthesized compounds were identified by SEM images. Magnetic moment values, UV-visible and IR spectral studies confirms the square planar geometry of chelates. However [VOL]Cl2 exists in octahedral geometry. Electron spin resonance spectra parameters of [CuL]Cl2 and [VOL]Cl2 complexes were well coinciding with proposed geometries. The in vitro biocidal activities of the compounds were done against some bacterial and fungal strains by disc diffusion method. Anticancer activity of Schiff base and copper complex were carried out by MTT method which reveals that the inhibition against the growth of breast cancer cell line culture for chelate is higher than Schiff base.

“…бактерий, грибов и вирусов, а также благодаря отсутствию формирования резистентности у микроорганизмов по отношению к серебру [10][11][12][13]. Однако непосредственное добавление наночастиц серебра имеет некоторые недостатки: покрытие или вещество с течением времени приобретает желто-коричневый цвет и ускоряется процесс его разложения [14].…”

Создание антимикробных нанокомпозитов является актуальным направлением в борьбе с микробным обсеменением и биопленкообразованием у микроорганизмов. Существующие методы получения нанокомпозитов на основе наночастиц серебра достаточно трудоемки, затратны и неэкологичны, в связи с чем возникла необходимость разработки нового метода их синтеза, удовлетворяющего указанным выше требованиям. Впервые проведен синтез наночастиц серебра и получен новый нанокомпозит с использованием нанотрубок галлуазита и ультразвука. Просвечивающая электронная микроскопия показала наличие наночастиц серебра на поверхности и внутри нанотрубок галлуазита, а картирование образца – равномерное распределение наночастиц серебра в нанокомпозите. Установлено, что полученный нанокомпозит обладает антибактериальной активностью в отношении бактерий Serratia marcescens более чем в 2 раза относительно контроля. Метод движения по типу роения показал, что диаметр миграции у штамма S. marcescens составил 2.05 ± 0.05 см, а с нанокомпозитом – 1.63 ± 0.04 см, что свидетельствует о способности ингибировать формирование биопленок у данных бактерий. Полученный нанокомпозит в дальнейшем может быть применен в качестве добавки к различным материалам или в качестве покрытия для борьбы с бактериальным обсеменением различных поверхностей и материалов.

A template synthesis of 18-membered tetraaza macroyclic ligand and this ligand were complexes with cobalt, nickel, copper and zinc metals chlorides. These synthesized complexes were characterized by various physicochemical methods such as elemental analysis, molar conductance, magnetic properties, spectral studies of infra-red, electronic spectrum, the redox properties of metal complexes were determined in the cyclic voltammetry and antibacterial activity. This research studies were clarifies the structure of the metal complexes were using with spectral data and molar conductance of the complexes. The structure of Co (II), Ni (II) and Cu (II) transition metal complexes was octahedral and Zn (II) complex was tetrahedral. These transition metal complexes were coordinated through the four nitrogen atoms of the ligand. The molar conductance studies revealed that Co (II), Ni (II) and Cu (II) complexes were non-ionic (1:0) and Zn (II) complex was ionic (1:2) in nature. The invitro antibacterial activity method exhibited all the complexes were good antibacterial activities.
