Administration of Sch B significantly inhibits glycogen synthase kinase 3 (GSK3) activation in the hippocampus and cortex neurons of triple-transgenic Alzheimers disease (3 Tg AD) mice, upregulates Nrf2, GPX4, and ferroptosis suppressor protein 1 (FSP1) expression, reduces levels of MDA, Fe 2+ , ROS, and tumor necrosis factor alpha (TNF-), thereby suppressing neuronal ferroptosis and neuroinflammation and improving learning and memory performance

FOXO4-DRI is a large peptide (~5382 Da, 48 amino acids) with a critical structural modification: the D-Retro-Inverso (DRI) design uses D-amino acids in reversed sequence to confer protease resistance while maintaining the 3D spatial arrangement needed for target binding

Peptides in particular have been found to have antimicrobial properties and provide assistance in biological functions such as immune response regulation and host defense 7
