Cancer cells exhibit a remarkable ability to adapt their metabolism to fuel rapid growth and survival, often relying heavily on nutrients like glutamine. This metabolic reprogramming has become a significant focus for developing novel cancer therapies. Glutaminase (GLS) plays a central role in glutamine metabolism, and inhibitors targeting this enzyme, such as CB-839, hold considerable promise. This article explores the promise of GLS1 inhibitors in targeting cancer's metabolic vulnerabilities.

CB-839 is a potent, selective, and non-competitive inhibitor of glutaminase GLS1, a key enzyme responsible for converting glutamine into glutamate. This makes it a crucial pharmaceutical intermediate for researchers investigating cancer metabolism. By blocking GLS1, CB-839 can effectively disrupt the energy and biosynthetic pathways that cancer cells depend on, leading to reduced proliferation and enhanced cell death. Its specific targeting of GLS1 over GLS2 further enhances its therapeutic potential and reduces off-target effects.

The therapeutic promise of CB-839 is evident in its significant antiproliferative and antitumor activities observed in preclinical studies. It has shown remarkable efficacy in models of triple-negative breast cancer (TNBC) and non-small cell lung cancer (NSCLC). Furthermore, CB-839 has demonstrated synergistic effects when combined with established chemotherapies such as Paclitaxel and Erlotinib. These combination strategies can amplify the metabolic stress on cancer cells, leading to more profound therapeutic responses. The oral bioavailability of CB-839 also contributes to its potential as a clinically viable treatment option.
