AB  - Two azo dye ligands, bearing different substituents (chlorine atom or methoxy group) in the para-position of the phenyl ring, were employed for the synthesis of two Cu(II) chelates. Full structural affirmation of complexes was assessed. X-ray diffraction measurements revealed that the coordination geometry for Cu atoms in both complexes is square-pyramidal with a ligand:metal ratio of 2:1 where dyes behave as monobasic bidentate ligands. Thermogravimetric analyses of the complexes and their starting dyes were performed to study their thermal stabilities and decomposition behavior confirming the thermal stability of both dyes and complexes. Antioxidative activity of the complexes has been assigned and compared with their parent ligands revealing that the presence of the electron–donor, methoxy group, in the phenyl ring, in both dye and complex, is responsible for the activity (IC50 values of 1.54 for the dye and 1.30 mM for the complex). It should be stated that the complexation of the methoxy-substituted dye leads to enhanced antioxidative activity concurrent to a standard antioxidant molecule of ascorbic acid, making this molecule a promising antioxidant agent. Docking study with vascular endothelial growth factor receptor 2 and Aurora kinase A proteins indicate that complexes exhibit higher binding affinities to proteins than the starting ligand dyes. The most promising structure exhibiting the best docking potential toward both proteins is the complex-bearing methoxy group. The presented results represent a promising start for further investigations of these compounds as potential therapeutic candidates for the treatment of various types of cancer.

AB  - Series of twenty-four 2-pyridone derivatives were screened and selected using the antioxidant ABTS assay
in order to find the most prominent compounds for further in vitro and in silico analyses. Seven derivatives with the highest antioxidant activities were selected and evaluated by β-carotene bleaching assay,
where all of the compounds exhibited better activities than standard antioxidant substance, vitamin C.
Furthermore, seven selected 2-pyridones exhibited significant anti-neuroinflammatory activity by reducing the production of pro-inflammatory mediators (ROS, NO, IL-6, and TNF-α) by LPS-stimulated BV2
microglial cells. Moreover, neuroprotective activity in microglia supernatant transfer model system on
SH-SY5Y neuronal cells has been observed. Anti-neuroinflammatory mechanisms of selected 2-pyridones
have been investigated by molecular docking studies of the TLR4 signaling pathway proteins as well as
inducible nitric oxide synthase. The present study suggests that selected 2-pyridone derivatives can alleviate neuroinflammation in microglial cells and protect the surrounding neuronal cells from damage,
which qualifies them for further investigations towards neurodegenerative diseases associated with inflammation.

AB  - The present study aimed to investigate the neuroprotective effects of the vitamin B complex (B1, B2, B3, B5, B6, and B12—VBC), by studying the changes in the femoral nerve, quadriceps muscle, popliteal lymph nodes and gut microbiota in the rat model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE). VBC treatment attenuated clinical signs of EAE during the disease, and reduced the duration of EAE thereby contributing to a faster recovery. In VBC-treated EAE rats, a significant decrease in nerve and muscle nuclear density was revealed during the onset period of the disease, while a marked increase was detected at the end of the disease, compared with untreated EAE rats. In the lymph nodes of VBC-treated EAE rats, a fewer number of lymphoid follicles in the cortical area and smaller epithelioid granulomas were detected. The changes in microbiota composition were examined using 16S rRNA gene sequencing and bioinformatics analysis, which revealed the potential of VBC treatment in establishing and/or maintaining gut microbiota homeostasis. Finally, the present study demonstrated that VBC treatment ameliorated the cellular changes in the affected peripheral nerve, muscles innervated by this nerve, and the gut microbiota dysbiosis which occurred during the EAE.
