R-GNE-140

R-GNE-140 a novel potent lactate dehydrogenase (LDHA) inhibitor with IC50 3nM for LDHA and 5 nM for LDHB. In MIA PaCa-2 human pancreatic cells, LDHA inhibition rapidly affected global metabolism, although cell death only occurred after 2 d of continuous LDHA inhibition. Pancreatic cell lines that utilize oxidative phosphorylation (OXPHOS) rather than glycolysis were inherently resistant to GNE-140, but could be resensitized to GNE-140 with the OXPHOS inhibitor phenformin. Acquired resistance to GNE-140 was driven by activation of the AMPK-mTOR-S6K signaling pathway, which led to increased OXPHOS, and inhibitors targeting this pathway could prevent resistance.

How to use

In Vitro:

GNE-140 inhibits proliferation in 37 of 347 cancer cell lines tested at a potency cut off of 5 μM. (R)-GNE-140 shows inhibitory effect on two chondrosarcoma (bone) cancer cell lines that harbor IDH1 mutations, with IC50 of 0.8 μM.

In Vivo:

GNE-140 (5 mg/kg) has high bioavailability in mice. At higher oral doses, ranging from 50 to 200 mg/kg, (R)-GNE-140 displays greater exposure.
