Biological Activity

Description

MRT68921 is a potent and dual autophagy kinase ULK1/2 inhibitor with IC50 of 2.9 nM and 1.1 nM, respectively.

Targets

ULK2 ^[1] (Cell-free assay)	ULK1 ^[1] (Cell-free assay)
1.1 nM	2.9 nM

In vitro
In vitro	MRT68921 specifically disrupts autophagosome maturation and thus blocks autophagic flux through ULK1 inhibition. ^[1]
Kinase Assay	Kinase Assays
Kinase Assay	Initial ULK1 kinase assays are performed with GST-ULK1, produced in Sf9 cells, which is described on the MRC-PPU Reagents website. For other experiments, recombinant GST-ULK1 (wild type, kinase-dead (K46I), and M92T and M92Q) is expressed in 293T cells, purified, and eluted from a glutathione-Sepharose column. Kinase assays are carried out in 50 mM Tris-HCl, pH 7.4, 10 mM magnesium acetate, 0.1 mM EGTA, and 0.1% β-mercaptoethanol, containing 30 μM cold ATP, and 0.5 μCi of [γ-32P]ATP for 5 min at 25 °C. Prior to ATP addition, reaction mixes are prewarmed to 25 °C for 5 min. Reactions are stopped by the addition of sample buffer, followed by SDS-PAGE, transfer to nitrocellulose, and analysis by autoradiography and immunoblot.
Cell Research	Cell lines	MEFs and 293T cells
	Concentrations	1 μM
	Incubation Time	1 h
	Method	MEFs and 293T cells were grown in DMEM, supplemented with 10% fetal bovine serum and penicillin/streptomycin, and cultured at 37 °C, 5% CO2. For induction of autophagy, cells were typically grown to 75% confluency, washed twice, and incubated in Earle's balanced salt solution (EBSS) for 1 h (or complete medium as a control) in the presence or absence of 10 μM MRT67307, 1 μM MRT68921, or 50 nM bafilomycin A1 and followed by lysis and immunoblotting with the indicated antibodies.

In Vivo
In vivo	MRT68921 is a potent and dual autophagy kinase ULK1/2 inhibitor.
Animal Research	Animal Models	Female BALB/c mice
	Dosages	20 mg/kg
	Administration	s.c.
