| Hazard Information | Back Directory | [Uses]
EN6 is a small-molecule in vivo autophagy activator that covalently targets cysteine 277 in the ATP6V1A subunit of the lysosomal v-ATPase. EN6-mediated modification of ATP6V1A uncouples v-ATPase from Rag, leading to inhibition of mTORC1 signalling, increased lysosomal acidification, and activation of autophagy. EN6 also scavenges TDP-43 aggregates (causative agents of frontotemporal dementia) in a lysosome-dependent manner[1]. | [Biological Activity]
EN6 is an autophagy activator th at simultaneously upregulates lysosomal vacuolar H(+)-ATPase (v-ATPase) activity and induces its decoupling from the Rag GTPases by covalently targeting v-ATPase subunit ATP6V1A Cys277. EN6 blocks mTORC1 lysosomal recruitment & activation (1-4 hr 25 μM EN6 pretreatment prior to 10-min amino acids (AA) stimulation of AA-starived HEK293) and clears cellular TDP-43 aggregates (25 μM; U2OS with inducible TDP-43). When administered in mice in vivo (50 mg/kg ip.)EN6 inhibits mTORC1 signaling and activates autophagy in both skeletal muscle and heart tissue. Unlike bafilomycin A1 (BafA1)EN6 activatesbut not inhibits v-ATPase catalytic activity. | [in vivo]
EN6 (50 mg/kg; i.p.; single) inhibits mTORC1 and activates autophagy in vivo[1]. | Animal Model: | Six-week-old male C57BL/6 mice[1]. | | Dosage: | 50 mg/kg | | Administration: | Intraperitoneal injection; single | | Result: | Significantly inhibited mTORC1 signaling in both skeletal muscle and heart, as demonstrated by reduced phosphorylation of S6, 4EBP1 and ULK1.
Strongly activated autophagy as shown by heightened LC3BII levels and reduced p62 levels.
