Dihexa

**Product Name:** Dihexa **Chemical Classification:** Angiotensin IV-derived Peptidomimetic **Molecular Formula:** $C_{27}H_{44}N_{4}O_{5}$ ### Scientific Overview and Mechanism of Action Dihexa is a high-affinity, small-molecule peptidomimetic derived from the N-terminal sequence of Angiotensin IV. In laboratory research settings, Dihexa is distinguished by its ability to act as a potent agonist of the Hepatocyte Growth Factor (HGF) and its high-affinity receptor, c-Met. Unlike many endogenous peptides, Dihexa was engineered to overcome the rapid metabolic degradation typical of linear peptide chains, demonstrating significantly enhanced metabolic stability. Its primary mechanism involves the potentiation of HGF signaling, which facilitates the dimerization of the c-Met receptor. Activation of the HGF/c-Met axis is a critical pathway in cellular biology, primarily associated with the induction of mitogenesis, motogenesis, and morphogenic activities across various cell lines. ### Preclinical Research Interest Research interest in Dihexa centers largely on its influence on synaptogenesis and cellular repair mechanisms within *in vitro* models. Preclinical studies have focused on the compound’s ability to promote the formation of new functional synaptic connections—a process observed to occur at picomolar concentrations. Unlike standard neurotrophic factors, such as Brain-Derived Neurotrophic Factor (BDNF), Dihexa exhibits a capacity to enhance spinogenesis and synapse formation in primary neuronal cultures with high potency. Furthermore, researchers utilize Dihexa to investigate its potential in mitigating cellular damage induced by neurotoxic stressors, making it a valuable tool for studying tissue regeneration, cellular signaling cascades, and the structural plasticity of neuronal architectures. ### Handling, Reconstitution, and Storage Dihexa is supplied as a lyophilized powder and should be stored at -20°C for long-term stability. For *in vitro* laboratory use, the compound is typically reconstituted in Dimethyl Sulfoxide (DMSO) or ethanol, as it exhibits limited solubility in purely aqueous buffers. Once reconstituted, stock solutions should be divided into single-use aliquots and stored at -80°C to prevent degradation through repeated freeze-thaw cycles. To maintain the integrity of the compound, it is essential to minimize exposure to direct light and ensure all handling is performed using aseptic laboratory techniques. *** **DISCLAIMER:** This product is intended for **IN-VITRO RESEARCH AND LABORATORY USE ONLY.** This compound is not a drug, food, or cosmetic and may not be used for human or veterinary administration.
