Dynamin-related GTPase DRP1 partial inhibitor (IC50 = 1.2 μM). Selective for DRP1 over other dynamin-related GTPases, OPA1 and DYN1. Increases mitochondrial DNA levels in mfn1- knockout MEFs deficient in mitochondrial fusion.

RTIL 13 is a highly effective inhibitor of dynaminGTPase, exhibiting an IC50 value of 2.3 μM for dynamin I GTPase. Furthermore, it selectively interacts with the pleckstrin homology lipid binding domain. This compound effectively suppresses both receptor-mediated and synaptic vesicle endocytosis, demonstrating IC50 values of 9.3 μM and 7.1 μM, respectively.
Ellipticine quinone, also known as NSC-383230, is a Drp1 inhibitor. rpitor1 and Drpitor1a inhibited the GTPase activity of Drp1 without inhibiting the GTPase of dynamin 1. Ellipticine quinone showed greater potency than the current std. Drp1 GTPase inhibitor, mdivi-1, (IC50 for mitochondrial fragmentation are (0.06, and 10 μM, resp.). Ellipticine quinone suppressed lung cancer tumor growth in a mouse xenograft model. Ellipticine quinone also inhibited mitochondrial ROS prodn., prevented mitochondrial fission, and improved right ventricular diastolic dysfunction during IR injury.
Cell-permeable version of dynamin inhibitory peptide, an inhibitor of the GTPasedynamin that competitively blocks binding of dynamin to amphiphysin, preventing endocytosis. Reduces NMDA receptor internalization.
Dynamin-related protein 1 (Drp1) inhibitor, inhibits Drp1 GTPase activity. Displays no effect on dynamin 1 or other mitochondrial dynamics-related proteins. Inhibits mitochondrial fission, dysfunction and reactive oxygen species (ROS) production in vitro.
Control peptide version of dynamin inhibitory peptide, myristoylated, an inhibitor of the GTPasedynamin that competitively blocks binding of dynamin to amphiphysin, preventing endocytosis. In contrast to dynamin inhibitory peptide, has no significant eff
