AUTEN-99 is an inhibitor of the phosphatase myotubularin-related protein 14 (MTMR14/Jumpy).1 It inhibits MTMR14/Jumpy activity in a cell-free assay when used at concentrations of 10 and 100 µM. AUTEN-99 (1 and 10 µM) enhances autophagic flux and increases the levels of LC3B-11 in HeLa cells. It increases survival of mouse primary neurons exposed to hydrogen peroxide as a model of oxidative stress when used at concentrations ranging from 0.5 to 5 µM. AUTEN-99 increases the number of autophagic structures in mouse pancreas, kidney, and liver following oral or intraperitoneal administration. It also induces autophagy in the Drosophila larval fat body and increases the percentage of flies climbing a glass column in a climbing assay in a transgenic model of Parkinson's disease.
