In neurobiology, cellular electrophysiology, and molecular neuroscience, it serves as a primary reference tool for investigating synaptogenic mechanisms and dendritic spine induction via modulation of the <strong>HGF\/c-Met<\/strong> signaling axis:<\/p>\n<ul>\n<li><strong>Potent Activation of the HGF\/c-Met Pathway:<\/strong> Acts as a potent allosteric facilitator of dimerization and autophosphorylation of the <strong>c-Met<\/strong> receptor tyrosine kinase in the presence of hepatocyte growth factor (HGF), significantly outperforming endogenous neurotrophic factors (e.g., BDNF) in inducing de novo synaptic connections in vitro.<\/li>\n<li><strong>Potentiation of Spinogenesis &amp; Synaptogenesis in Hippocampal Cultures:<\/strong> Markedly increases dendritic spine density, synaptic marker expression (synaptophysin, PSD-95), and miniature excitatory postsynaptic current (mEPSC) frequency in primary hippocampal and cortical neuron cultures.<\/li>\n<li><strong>Engagement of Intracellular Survival Cascades (Akt \/ ERK1\/2):<\/strong> Triggers downstream phosphorylation of PI3K\/Akt and MAPK\/ERK1\/2 cascades, protecting neuronal cell lines against \u03b2-amyloid toxicity, oxidative stress, and glutamate excitotoxicity in vitro.<\/li>\n<li><strong>High Chemical Stability in a Solid Matrix:<\/strong> Encapsulation provides a robust analytical carrier protected from atmospheric degradation and enzymatic cleavage, ensuring accurate serial dilutions for in vitro bioassays.<\/li>\n<\/ul>\n<p><strong>Technical &amp; Chemical Specifications<\/strong><\/p>\n<ul>\n<li><strong>Classification:<\/strong> Peptidomimetic HGF\/c-Met Axis Agonist in Solid Matrix \/ Reagent Analytical Capsules (RUO)<\/li>\n<li><strong>Chemical Name:<\/strong> N-hexanoyl-L-tyrosyl-L-isoleucyl-6-aminohexanamide<\/li>\n<li><strong>Molecular Formula:<\/strong> C27H44N4O5<\/li>\n<li><strong>Molecular Weight:<\/strong> 504.66\u00a0g\/mol<\/li>\n<li><strong>Active Content:<\/strong> 5 mg per capsule (\u00b12%)<\/li>\n<li><strong>Packaging Unit:<\/strong> 60 research capsules in a laboratory container with integrated desiccant<\/li>\n<li><strong>Form:<\/strong> Solid reagent matrix \/ encapsulated standard<\/li>\n<li><strong>Component Identification:<\/strong> Verified via Analytical HPLC and Mass Spectrometry (MS \/ NMR)<\/li>\n<li><strong>Recommended Reconstitution Protocol:<\/strong> Capsule contents are intended for dissolution in suitable laboratory solvents (e.g., DMSO for concentrated stock solutions or sterile laboratory buffers) to prepare calibrated test solutions for in vitro cellular assays.<\/li>\n<li><strong>Storage Conditions:<\/strong> Store at 15\u201325 \u00b0C in a dry, dark environment in the tightly sealed original container with desiccant.
