Implication

In vitro study demonstrates that novel peptide dimethylammonium salts promote neural stem cell differentiation and neuroprotection, suggesting new avenues for stroke therapies.

Key Points

Synthesize a series of novel heptapeptides and characterize their potential to induce neural differentiation and protect neuronal networks under ischemic conditions.
Synthesized 19 heptapeptides and used DOSY NMR spectroscopy to confirm the spontaneous formation of a dimethylammonium (DMA) salt adduct on lead peptide 3 (LSAVTFG.DMA).
Performed L- and D-alanine scanning mutagenesis on peptide 3 to generate 16 analogs for structure-activity relationship analysis.
Evaluated lead peptides in vitro for neural progenitor/stem cell differentiation, proliferation, and neuroprotection under oxygen-glucose deprivation/reperfusion (OGD/R) and hypoxia/reperfusion insults.
Peptide 3 promoted neural differentiation in vitro at a concentration of 100 μM.
Alanine scan analogs L1A.DMA (13) and S2A.DMA (15) exhibited potent differentiation activity in neural progenitor and stem cells.
Lead peptides enhanced cell survival, restored cellular morphology, increased proliferation, and preserved neuronal network integrity during OGD/R and hypoxia/reperfusion stress.
