    Compounds that act on mitochondrial functions are considered as promising drugs for the treatment of neurodegenerative diseases and age-related dementias. As a basis for the creation of such potential drugs, bioisosteric cinnamic acid analogs and polymethoxybenzene derivatives were selected. Derivatives of cinnamic acid have a wide range of biological activities, which can be important for drugs aimed at the treatment of neurodegenerative diseases, in particular Alzheimerβ€²s disease. In this work, the neuroprotective activity of bioisosteric cinnamic acid analogs and polymethoxybenzene derivatives was studied. Among the compounds studied, lead substances 3, 4, and 7 have been identified. These compounds show no intrinsic toxicity and have a neuroprotective effect on the cellular model of neurodegeneration associated with calcium stress. The mechanism of their cytoprotective activity is probably due to the influence on mitochondrial functions, because these compounds effectively suppress the calcium-induced process of mitochondrial permeability jump. In addition, one of the substances investigated (7) has antioxidant properties, showing the ability to inhibit lipid peroxidation (LPO) of rat brain homogenate, which may be an additional mechanism of neuroprotective effect. The data obtained make it possible to recommend the investigated substances as a basis for the creation of effective neuroprotective drugs capable of influencing early stages of the development of neurodegenerative diseases.БоСдинСния, Π½Π°ΠΏΡ€Π°Π²Π»Π΅Π½Π½ΠΎ Π΄Π΅ΠΉΡΡ‚Π²ΡƒΡŽΡ‰ΠΈΠ΅ Π½Π° ΠΌΠΈΡ‚ΠΎΡ…ΠΎΠ½Π΄Ρ€ΠΈΠ°Π»ΡŒΠ½Ρ‹Π΅ Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΈ, Ρ€Π°ΡΡΠΌΠ°Ρ‚Ρ€ΠΈΠ²Π°ΡŽΡ‚ΡΡ ΠΊΠ°ΠΊ пСрспСктивныС лСкарствСнныС ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚Ρ‹ для лСчСния Π½Π΅ΠΉΡ€ΠΎΠ΄Π΅Π³Π΅Π½Π΅Ρ€Π°Ρ‚ΠΈΠ²Π½Ρ‹Ρ… Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ ΠΈ возрастных Π΄Π΅ΠΌΠ΅Π½Ρ†ΠΈΠΉ.

    Ru(III) complexes with lonidamine-modified ligands

    A series of bifunctional Ru(III) complexes with lonidamine-modified ligands (lonidamine is a selective inhibitor of aerobic glycolysis in cancer cells) was described. Redox properties of Ru(III) complexes were characterized by cyclic voltammetry. An easy reduction suggested a perspective for these agents as their whole mechanism of action seems to be based on activation by metal atom reduction. New compounds demonstrated a more pronounced antiproliferative potency than the parental drug; individual new agents were more cytotoxic than cisplatin. Stability studies showed an increase in the stability of complexes along with the linker length. A similar trend was noted for antiproliferative activity, cellular uptake, apoptosis induction, and thioredoxin reductase inhibition. Finally, at concentrations that did not alter water solubility, the selected new complex evoked no acute toxicity in Balb/c mice. Β© 2021 by the authors. Licensee MDPI, Basel, Switzerland
