Overview

product description：

Hydroxy Dynasore (Dyngo-4a), a structural analog of Dynasore (HY-15304), is an potency improved, low cytotoxicity and non‐specific binding dynamin inhibitor with IC50 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 IC50 of 5.7 μM in vitro.
