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].
