Questions And Answer | Back Directory | [Description]
CB-839 is a potent, selective, and orally bioavailable glutaminase inhibitor with IC50 of 24 nM for recombinant human GAC. Phase 1. | [In vitro]
CB-839 exhibits time-dependent and slowly reversible kinetics. IC50 values for glutaminase inhibition by CB-839 following preincubation with rHu-GAC for-1 hour are < 50 nmol/L, at least 13-fold lower than with BPTES. CB-839 has antiproliferative activity in a triple-negative breast cancer (TNBC) cell line, HCC-1806, while no antiproliferative activity is observed in an estrogen receptor–positive cell line, T47D. | [In vivo]
In the mouse TNBC model, single agent CB-839 (200 mg/kg, p.o.) suppresses tumor growth by 61% relative to vehicle control. In the mouse JIMT-1 xenograft model, CB-839 alone (200 mg/kg, p.o.) results in 54% tumor growth inhibition (TGI) relative to vehicle control, combination of CB-839 (200 mg/kg, p.o.) with paclitaxel (10 mg/kg, p.o.) largely suppresses the regrowth of the tumors resulting in a TGI relative to vehicle control of 100%. |
Hazard Information | Back Directory | [Uses]
CB-839 performs an antileukemic activity. It Inhibits GLS1 genes and reduces oxidative phosphorylation leading to leukamic cell proliferation arrest and apoptosis. | [storage]
