MHY1485

Description

MHY1485 is a cell-permeable activator of mTOR that has been shown to increase levels of cellular mTOR Ser²⁴⁴⁸ and downstream substrate 4E-BP Thr^37/46 phosphorylation in rat liver Ac2F cells. It can induce cellular LC3-II accumulation in Ac2F cells and has been shown to inhibit autophagy by suppressing the fusion between autophagosomes and lysosomes.

The Uses of MHY1485

MHY1485 has been used:

• to study the effect of mammalian target of rapamycin mTOR signalling on in vitro O-GlcNAcylation
• to inhibit autophagy
• as a mTOR agonist to demonstrate that the O-linked N-acetylglucosamine transferase- RNA helicase p68 (OGT-DDX5) axis regulates colorectal cancer cell proliferation and metastasis

Biochem/physiol Actions

MHY1485 is mTOR activator that potently inhibits autophagy by suppression of fusion between autophagosomes and lysosomes.
