In vitro study | 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 antiselective activity is observed in an estrogen receptor-positive cell line, T47D. CB-839 exhibits time-dependent and slowly reversible kinetic properties. After preincubation with rHu-GAC for 1 hour, CB-839 inhibited glutaminase with an IC50 value of <50 nmol/L, at least 13-fold lower than that of BPTES. CB-839 has anti-proliferative activity on the triple negative breast cancer (TNBC) cell line, HCC-1806, and no anti-proliferative activity on the estrogen receptor positive cell line, T47D. |
In vivo study | 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 sum up the growth of the masses resulting in a TGI relative to vehicle control of 100%. In the mouse TNBC model, a single dose of CB-839 (200 mg/kg, p.o.) tumor growth was inhibited by 61% relative to the vehicle control. In the mouse JIMT-1 xenograft model, CB-839 was administered alone (200 mg/kg, p.o.) resulted in 54% tumor growth inhibition (TGI) relative to vehicle control, CB-839 (200 mg/kg, p.o.) and paclitaxel (10 mg/kg, p.o.) the combination significantly inhibited tumor regrowth, resulting in 100% tumor growth inhibition (TGI) relative to the vehicle control. |
