The study demonstrated neuroprotective action of novel chemical agent, potassium salt of comenic acid, against the glutamate-induced cytotoxicity on the model of cultured cerebral neurons. Potassium comenate (0.001-1.0 mM) significantly decreased the rate of glutamateinduced neuronal death. The highest viability of the cultured neurons during postglutamate time was observed when potassium comenate was applied in a concentration of 0.1 mM.

Article Synopsis
- Comenic acid, a gamma-pyrone derivative, activates opioid-like receptors that influence Na1.8 channels in sensory neurons, suggesting its potential as a pain-reliever.
- This research uniquely combines live neuron data with quantum chemical calculations to explore how gamma-pyrone structures relate to their physiological effects.
- The study highlights the importance of calcium binding in gamma-pyrones, which alters their electrostatic properties and facilitates ligand-receptor interactions crucial for their analgesic activity.

Oxidative stress has been implicated in the pathogenesis of many neurodegenerative diseases, and particularly in Alzheimer's disease. This work describes the Ugi multicomponent synthesis, antioxidant power and Nrf2 pathway induction in antioxidant response element cells of ()--(2-((2-(1-indol-3-yl)ethyl)amino)-2-oxoethyl)--(2-(5-(benzyloxy)-1-indol-3-yl)ethyl)-3-(4-hydroxy-3-methoxyphenyl)acryl amides , -(2-((2-(1-indol-3-yl)ethyl)amino)-2-oxoethyl)--(2-(5-(benzyloxy)-1-indol-3-yl)ethyl)-5-(1,2-dithiolan-3-yl)pentanamides and -(2-((2-(1-indol-3-yl)ethyl)amino)-2-oxoethyl)--(2-(5-(benzyloxy)-1-indol-3-yl)ethyl)-5-hydroxy-4-oxo-4-pyran-2-carboxamides . We have identified compounds and , showing a potent antioxidant capacity, a remarkable neuroprotective effect against the cell death induced by HO in SH-SY5Y cells, and a performing activation of the Nrf2 signaling pathway, as very interesting new antioxidant agents for pathologies that curse with oxidative stress.
