Cat. No.: HY-120877
Handling Instructions

MRT199665 is a potent and ATP-competitive, selective MARK/SIK/AMPK inhibitor with IC50s of 2/2/3/2 nM, 10/10 nM, and 110/12/43 nM for MARK1/MARK2/MARK3/MARK14, AMPKα1/AMPKα2, and SIK1/SIK2/SIK3, respectively. MRT199665 causes apoptosis in MEF2C-activated human acute myeloid leukemias (AML) cells. MRT199665 inhibits the phosphorylation of SIK substrate CRTC3 at S370.

Description

MRT199665 is a potent and ATP-competitive, selective MARK/SIK/AMPK inhibitor with IC50s of 2/2/3/2 nM, 10/10 nM, and 110/12/43 nM for MARK1/MARK2/MARK3/MARK14, AMPKα1/AMPKα2, and SIK1/SIK2/SIK3, respectively[1]. MRT199665 causes apoptosis in MEF2C-activated human acute myeloid leukemias (AML) cells[2]. MRT199665 inhibits the phosphorylation of SIK substrate CRTC3 at S370[3].

In Vitro

MRT199665 (1 μM; pre-treated for 1 h) increases LPS (100 ng/mL; stimulated for up to 24 h)-stimulated IL-10 mRNA and Nurr77 mRNA production, and IL-10 secretion[1].
MRT199665 (1 nM-100 μM; 48 hours) reduces leukemia growth[2].
MRT199665 treatment can block MEF2C S222 phosphorylation in acute myeloid leukemias (AML) cells. MRT199665 (10 nM-1000 nM; 12 hours) leads to a dose-dependent reduction in total and pS222 MEF2C. MRT199665 also causes a decrease of total MEF2C protein[2].

Western Blot Analysis[2]

Cell Line: OCI-AML2 and MOLM-13 cells
Concentration: 10, 100, 500, and 1000 nM
Incubation Time: 12 hours
Result: Led to a dose-dependent reduction in total and pS222 MEF2C, causing more than 40% reduction in MEF2C phosphorylation at 10 nM as compared to untreated cells.

Cell Proliferation Assay[2]

Cell Line: Human AML cell lines OCI-AML2, MV4-11, MOLM-13 and Kasumi-1 with endogenous MEF2C phosphorylation; human AML cell lines NB-4, HEL, HL-60 and U937 lacking MEF2C
Concentration: 1 nM, 10 nM, 100n M, 1 μM, 10 μM, 100μM
Incubation Time: 48 hours
Result: Human AML cell lines with endogenous MEF2C phosphorylation (OCI-AML2, MV4–11, MOLM-13 and Kasumi-1) were more sensitive as compared to cell lines lacking MEF2C (NB-4, HEL, HL-60 and U937), with mean IC50 of 26±13 versus 990±29 nM, respectively.
