Description

Hydroxy Dynasore (Dyngo-4a), a structural mimetic analog of Dynasore (HY-15304), is an improved, less cytotoxic and versatile dynamin inhibitor with IC50 values ​​of 0.38 μM and 2.3 μM for brain recombinant dynamin I and recombinant mouse dynamin II, respectively. Hydroxy Dynasore inhibits dynamin-dependent transferrin endocytosis with an IC50 of 5.7 μM.

In Vitro

Dynamin is a large GTPase enzyme that severs membrane-bound clathrin-coated vesicles. Endocytosis internalizes portions of cells’ plasma membrane along with extracellular material, is fundamentally important in cell physiology.
Hydroxy Dynasore inhibits Dynamin I (Dyn I) activity with IC50 values of 2.7 μM and 0.38 μM with or without 0.06% Tween-80 in the GTPase assay[1].
Hydroxy Dynasore shows an IC50 of 5.7 μM in clathrin-mediated endocytosis (CME) assay for inhibition of Tfn-A594 uptake in U2OS cells[1].
Hydroxy Dynasore shows IC50 values of 0.38 μM and 1.1 μM in absence of Tween-80, and exhibits IC50 values of 4.9 μM and 30.0 μM in presence of Tween-80, respectively. Hydroxy Dynasore is 2.1-fold selective for DynI versus DynII from Sf21 cells and DynII (recombinant protein from Sf21 cells) in this GTPase assay[1].
Hydroxy Dynasore prevents the uptake of BoNT/A-Hc in cultured hippocampal neurons and in motor nerve terminals[2].
Hydroxy Dynasore (1-100μM; 20 min prior to the addition of Alexa Fluor 488-BoNT/A-Hc) results in depolarization of Hippocampal neurons, it dose-dependently inhibits internalization of Alexa Fluor 488-BoNT/A-Hc with an IC50 of 16.0 ± 1.2 μM[2].

In Vivo

Hydroxy Dynasore (intraperitoneal injection; 30 mg/kg; 1.5-2 h before BoNT/A injection) provides protection again BoNT/A-induced paralysis in the phrenic nerve-hemidiaphragm twitch model in CD-1 mice[2].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (6.15 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
