<p style=/line-height:25px/>Dynasore is a cell-permeable small molecule that inhibits the GTPase activity of dynamin1, dynamin2 and Drp1, the mitochondrial dynamin.<br>IC50 Value: 15 uM [1]<br>Target: dynamin<br>Dynasore was discovered in a screen of approximately 16,000 compounds for inhibitors of the dynamin2 GTPase. Dynasore is a noncompetitive inhibitor of dynamin GTPase activity and blocks dynamin-dependent endocytosis in cells, including neurons[2].<br>in vitro: Dynasore inhibits dynamin GTPase activity and transferrin uptake at IC(50) approximately 15 microM but use in some biological applications requires more potent inhibitor than dynasore. Dynasore treatment led to the abnormal accumulation of LDL and free cholesterol (FC) within the endolysosomal network. The measure of cholesterol esters (CE) further showed that the delivery of regulatory cholesterol to the endoplasmic reticulum (ER) was deficient. This resulted in the inhibition of the transcriptional control of the three major sterol-sensitive genes, sterol-regulatory element binding protein 2 (SREBP-2), 3-hydroxy-3-methyl-coenzymeA reductase (HMGCoAR), and low-density lipoprotein receptor (LDLR)[3].<br>in vivo:<br></p>
