New synthetic derivatives of isoindoline-dione: synthesis, neuroprotection assay and impact on the expression level of oxidative stress-related genes in neuronal-like cell line.
Journal of Receptor and Signal Transduction Research 2024 January 26
PURPOSE: Oxidative stress can damage cells and cause age-related illnesses such as Alzheimer's, Parkinson's, and Huntington's. This study looked at newly synthesized isoindole derivatives and their effects on SH-SY5Y as a neuroblastoma cell under oxidative stress through the NRF2 signaling pathway. NRF2 transcription factor plays a vital role in the oxidative stress response and cellular homeostasis.
METHOD: Three isoindoline-dione derivatives were synthesized by reacting phthalic anhydrides with 4-(2-aminoethyl)-1-benzyl piperidine. Their structures were confirmed through FT-IR, NMR, and Mass spectroscopy. The derivatives were then tested on human SH-SY5Y cells under an oxidative stress model induced by hydrogen peroxide (H2 O2 ). The cell viability, ROS levels, protein carbonyl content, and gene expression of NRF2 and phase II antioxidative enzymes were measured after 24 h.
RESULTS: Three isoindoline derivatives (3a-3c) were observed to increase the viability of SH-SY5Y cells by protective against oxidative stress, reducing intracellular reactive oxygen species and carbonylated proteins, and increasing gene expression levels of NRF2 and associated genes such as NQO-1, and GSTK1.
CONCLUSION: Isoindoline derivatives demonstrated a neuroprotective effect on SH-SY5Y cells through various neuroprotective mechanisms, although more studies are needed.
