MRT68921 is a potent, selective and dual autophagy kinase ULK1/2 inhibitor with IC50 of 2.9 nM and 1.1 nM, respectively. It can inhibit ULK in vitro and block autophagy in cells. By generating the drug-resistant M92T ULK1 mutant, MRT68921demostrates to specifically block autophagic flux through ULK1 inhibition and disrupt autophagosome maturation, not through AMPK-related kinase involvement. ULK1 inhibition results in accumulation of stalled early autophagosomal structures, indicating a role for ULK1 in the maturation of autophagosomes as well as initiation.
How to Use:
In vitro: MRT68921 was usually used at 1 µM final concentration in vitro.
In vivo: n/a
