Biological Activity

Description

PKM2 inhibitor(Compound 3K, PKM2-IN-1) displays PKM2 inhibitory activity with the IC50 value of 2.95 μM. The IC50 value for PKM1 is 4-5-fold higher than that for PKM2.

Targets

PKM2 ^[1]
(Cell-free assay)

2.95 μM

In vitro

The well performing compound 3k shows nanomolar antiproliferative activity toward a series of cancer cell lines with high expression of PKM2 including HCT116, Hela and H1299 with IC50 values ranging from 0.18-1.56 μM. Moreover, compound 3k exhibits more cytotoxicity on cancer cells than normal cells^[1].

In vivo

Compound 3K (PKM2-IN-1) is an enzymatic inhibitor of pyruvate kinase M2 (PKM2).

Cell Assay:^{^[1]}	Cell lines HCT116, Hela, H1299, BEAS-2B Concentrations 0.078, 0.156, 0.313, 0.625 μM Incubation Time 48 h Method Cell viability is detected with the MTS assay. 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 or DMSO (as negative control) for 48 h. Then 20 μL MTS is added in per well and incubated at 37°C for 3h. 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.
