    We report herein the synthesis of new azomethine group containing forty-, sixty-eight- and seventy- two-membered macroheterocyclic compounds and the investigation of their activity against the neurob- lastoma cell line. The synthesis of targeted compounds was done by condensation of dialdehydes with polyamines and their structures were investigated by 1 H and 13 C NMR and MALDI MS methods. Anti- cancer activity of these newly synthesized molecules was studied in the neuroblastoma (SH-SY5Y) cell line at eight different concentrations (1–100 μg/ml) for 24 h, 48 hrs and 72 h by MTT method. In ad- dition to it, oxidative stress (GPX1, PRDX1, CAT, SOD1, NQO1) and DNA repair (ATR, ERCC1, CDKN1A, PRKDC) gene profiles were also investigated by RT-PCR method. It was found that all synthesized compounds showed the highest activity after 72 h of incubation. PRDX1 gene expression in the case of all investi- gated compounds was found to be higher than the control group, whereas ABCB1 (MDR) gene expression increased only in the case of molecule 1. Results also demonstrate that the expression levels of GPX and SOD1 genes were high in the case of molecule 2, whereas molecule 1 manifested low expression levels of ERCC1, ATR, CDKN1A, PRKDC, GPX1, ABCB1(MDR), CAT, SOD1 and NQO1 genes. Along with experimen- tal studies, theoretical studies were also carried out. The String v11 program was used to determine the interaction of proteins involved in oxidative stress and DNA repair mechanisms with other proteins. The results of the molecular docking analysis were found to be in good agreement with the experiments.

    Objective: Lung cancer is one of the most common cancers in the world. It is known that angiogenesis plays a role in the development and metastasis of lung cancer. Azomethine derivatives known as Schiff bases have many biological activities. In this study, we aimed to determine the anticancer activity of the newly synthesized azomethine derivative compound B-47/2 on lung cancer and to determine the effect of this component on vascular endothelial growth factor B (VEGFB) gene expression. Material and Method: Compound B-47/2 was synthesized for the first time. B-47/2 compound was applied to lung cancer cell line (A549) at varying concentrations (1-100 µg/mL) and its anticancer activity was found after 24, 48 and 72 hours incubations using the 3-

    Synthesis, nanostructuring and in silico studies of a new imine bond containing a macroheterocycle as a promising PBP-2a non-?-lactam inhibitor

    This study is devoted to the synthesis of a 40-membered macroheterocycle with its further nanostructuring by magnetite nanoparticles. The mentioned macroheterocycle was synthesized by the [2+2] cyclocondensation of the oxygen-containing diamine with an aromatic dialdehyde in a non-catalytic medium and with no work-up procedure. The structure of the obtained macroheterocycle was studied by H-1 and C-13 nuclear magnetic resonance spectroscopy and matrix-assisted laser desorption/ionization-time of flight mass spectrometry. Furthermore, the nanosupramolecular complex of macroheterocycles with magnetite nanoparticles was obtained and investigated by Fourier-transform infrared and ultraviolet-visible spectroscopy methods. Shifts in the infrared spectra of the nanosupramolecular complex indicate the interaction through metal-aromatic ring non-covalent bonding. The shift is also observed for the C-O-C stretching band of ether bonds. The loading rate of macroheterocycles on magnetite nanoparticles was 18.6%. The morphology of the ensemble was studied by transmission electron microscopy, which confirmed the synthesis of nanospherical particles with a diameter range of 10-20 nm. Powder X-ray diffraction analysis showed patterns of cubic Fe3O4 nanoparticles with a crystallite size equal to 9.1 nm. The macroheterocycle and its nanosupramolecular complex were tested against Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. The results have shown that the created complex has shown 64 times better activity against Staphylococcus aureus in comparison with the individual macroheterocycle and 32 times better activity in comparison with the pristine antibiotic Ampicillin as a control. In addition, computational analysis of the macroheterocycle was performed at the B3LYP/6-31G level in water. Molecular docking analyses for the macroheterocycle revealed Penicillin-binding protein PBP2a (5M18) from the transpeptidase family as a target protein in Staphylococcus aureus.
