PKM2-IN-1 is a pyruvate kinase M2 (PKM2) inhibitor with an IC₅₀ of 2.95 μM.

IC50: 2.95 μM (PKM2)^[1]

PKM2-IN-1 is a pyruvate kinase M2 (PKM2) inhibitor with an IC₅₀ of 2.95±0.53 μM. Results show that most of the tested compounds exhibit some degree of PKM2 inhibition and some compounds, such as PKM2-IN-1 (compound 3k) and 6d, display more potent activity than the positive control shikonin. The representative compounds PKM2-IN-1, 6d display dose-dependent inhibition of PKM2 with less inhibition of PKM1 and PKL like shikonin. Among all tested compounds, the most potent compounds are 3a, PKM2-IN-1 and 3r, which exhibit IC₅₀ values against HCT116 and Hela cells ranging from 0.39 to 0.41 μM, 0.18 to 0.29 μM and 0.18 to 0.38 μM, respectively^[1].

Cell lines (HCT116, Hela, H1299, BEAS-2B) are cultured in RPMI 1640 containing 9% fetal bovine serum (FBS) at 37°C in 5% CO₂. Cell viability is detected with the MTS assay according to the manufacturer’s instructions. Briefly, 5000 cells in per well are plated in 96-well plates. After incubated for 12 h, the cells are treated with different concentration of tested compound (including PKM2-IN-1) or DMSO (as negative control) for 48 h. Then 20 μL MTS is added in per well and incubated at 37°C for 3 h. Absorbance of each well is determined by a microplate reader at a 490 nm wavelength. The IC₅₀ values are calculated using Prism Graphpad software of the triplicate experiment^[1].
