UPGL00004 is a potent allosteric glutaminase C (GAC) inhibitor (IC50=29 nM; Kd=27 nM). UPGL00004 strongly inhibits the proliferation of highly aggressive triple-negative breast cancer cell lines[1].
UPGL00004 inhibits MDA-MB-231, HS578T and TSE cells with IC50s of 70, 129, and 262 nM, respectively[1].
The combination of UPGL00004 (1 mg/kg body weight) and Bevacizumab (2.5 mg/kg body weight) via intraperitoneal injection completely prevent any detectable increase in tumor size in a triple-negative breast cancer patient-derived tumor graft model[1].
