About Cortexin
Polypeptide bioregulator from bovine cortex; modulates neurotransmitter activity; activates GABA and dopamine systems; reduces excitotoxicity; stimulates neuronal repair
A cortex-derived polypeptide bioregulator widely used in Russia and Eastern Europe for cognitive enhancement and neuroprotection. Improves learning, memory, and EEG activity.
Research Areas
About FGL
Mimics NCAM-mediated signaling via FGFR (fibroblast growth factor receptor) activation. Stimulates downstream Erk1/2 and PLCγ pathways. Promotes long-term potentiation (LTP) and synaptogenesis.
A peptide derived from the fibronectin type III (FGL) module of neural cell adhesion molecule (NCAM). Promotes synaptic plasticity, memory formation, and neuroprotection in preclinical models by mimicking NCAM-mediated signaling.
