General description

Dynasore is a small molecule GTPase inhibitor that targets dynamin-1, dynamin-2 and Drp1 (mitochondrial). Dynasore blocks dynamin-dependent endocytosis, scission of endocytic vesicles. Dynosore is profibrotic, induces PAI-1 in pleural mesothelial cells, and may be an effective pleurodesing (pleurodesis) agent. Dynasor blocks human papillomavirus type 16 (HPV16) and bovine papillomavirus type 1 (BPV1) (pseudovirions) infections.
Dynasore hydrate lowers labile cholesterol in the plasma membrane and distorts lipid raft organization. Dynasore exhibits pleotropic effects on herpes simplex virus (HSV)-1 and HSV-2 infection. It hinders viral entry, trafficking of viral proteins and capsid formation.

Application

Dynasore hydrate has been used:
  • for priming fetal mesenchymal stem/stromal cells (fMSC)
  • in confocal microscopy
  • in wound healing/scratch and tube-formation assay
  • to analyse its effects on Coxsackievirus A9 (CAV9) infection
  • to inhibit clathrin-mediated endocytosis and caveolin-mediated endocytosis
  • in live imaging of cells

Biochem/physiol Actions

Dynasore is a cell-permeable, reversible noncompetitive dynamin 1 and dynamin 2 GTPase activity inhibitor.
