Dihexa
Based on 6 publication(s) in Google Scholar
Dihexa, an oligopeptide drug, is an orally active and blood-brain barrier-permeable angiotensin IV analog. Dihexa binds to hepatocyte growth factor (HGF) with high affinity (Kd=65 pM) and potentiates its activity at its receptor, c-Met. Dihexa exhibits excellent antidementia activity and improves cognitive function in animal models. Dihexa may have therapeutic potential as a treatment Alzheimer’s disease.

Biological Activity
Kd: 65 pM (HGF)[1]
Dihexa binds with high affinity to HGF and both dihexa and its parent compound Norleucine 1-AngIV induce c-Met phosphorylation in the presence of subthreshold concentrations of HGF and augment HGF-dependent cell scattering. Further, dihexa and Nle1-AngIV induce hippocampal spinogenesis and synaptogenesis similar to HGF itself. Dihexa effectively inhibits HGF dimerization at 1 μM. While dihexa at 1 nM and 10 pM alone does not activate c-Met, it markedly augments the capacity of HGF at 1.25 and 2.5 ng/mL to activate c-Met[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.95 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Rats: Serial dilutions of dihexa in 50% DMSO or water (for dilutions of 50 µg/mL or less) are prepared from the stock used to dose the animals to be used for preparation of a standard curve. 10 µL of each serial dilution is then added to 90 µL of blank plasma for final concentrations of 0.01, 0.02, 0.05, 0.1, 0.2, 1, 10, 20, 50, and 100 µg/mL. 80 µL of each plasma sample is transferred to previously prepared tubes containing 240 µL of ice-cold acetonitrile and vortexed vigorously. 10 µL of isotonic saline containing 100 µg/mL Nle-YI-(6) aminohexanoic amide as an internal standard is added to each sample on ice. The standard-curve plasma samples are then stored at −20°C and further processed alongside the pharmacokinetic study samples[2].
