Summary
Hydroxy Dynasore (Dyngo-4a), a structural analog of Dynasore (HY-15304), is an potency improved, low cytotoxicity and non‐specific binding dynamin inhibitor with IC 50 values of 0.38 μM and 2.3 μM for brain dynamin I and recombinant rat dynamin II, respectively. Hydroxy Dynasore inhibits dynamin‐dependent endocytosis of transferrin with an IC 50 of 5.7 μM in vitro.
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 IC
50
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 IC
50
of 5.7 μM in clathrin‐mediated endocytosis (CME) assay for inhibition of Tfn‐A594 uptake in U2OS cells
[1]
.
Hydroxy Dynasore shows IC
50
values of 0.38 μM and 1.1 μM in absence of Tween-80, and exhibits IC
50
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 IC
50
of 16.0 ± 1.2 μM
[2]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
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
