CB-839 is a potent, selective, and orally bioavailable glutaminase inhibitor with IC50 of 24 nM for recombinant human GAC. Phase 1.
Combination treatment with a GLS1 inhibitor and PP242 induces cell death. a The SKOV3 and A2780 cells were incubated with DMSO (control), PP242 (1 μM), CB839 (1 μM), or their combination for 48 h. Cell morphology images were obtained under a microscope. b. Expression of the activated cleaved PARP content to GAPDH was observed using Western blot. c. Cell death was evaluated by flow cytometry after Annexin V and PI staining. Data are presented as means of triplicate samples, and error bars reflect SD.
BPTES is a potent and selective Glutaminase GLS1 (KGA) inhibitor with IC50 of 0.16 μM. It has no effect on glutamate dehydrogenase activity and causes only a very slight inhibition of γ-glutamyl transpeptidase activity.
