Ki: 120 nM (APT-2)[1] IC50: 144 nM (LYPLA2)[2]

In Vitro ML349 is an inhibitor of acyl protein thioesterase 1 and 2 (APT-1 and APT-2) with Kis of >10000 and 120±20 nM, respectively[1]. ML349 is also an inhibitor of both LYPLA1 and LYPLA2 with IC50s of >3000 and 144 nM, respectivley[2]. ML348 and ML349 do not decrease cell viability, but they lead to a slight activation of AKT in NRAS mutant cells[3].
Cell Assay Cells are plated in 96-well plates with a density of 4000 to 8000 cells per well and incubated for 24 h at 37°C with 5% CO2. Then cells are treated with increasing drug (including ML349) concentrations and their combinations. Cell viability is measured with the cell viability assay according to the manufacturer's protocol[3].
