Cancer cells possess unique metabolic characteristics that enable their rapid proliferation and survival, even under adverse conditions. One of the most prominent metabolic alterations is the increased uptake and utilization of glutamine, a process often referred to as 'glutamine addiction.' This pathway is tightly regulated by the enzyme glutaminase (GLS), which converts glutamine into glutamate, a key substrate for various cellular processes, including the Krebs cycle and nucleotide synthesis. Understanding and targeting this pathway is a significant focus in cancer research, and compounds like CB-839 are crucial for these investigations.

CB-839 is a highly effective GLS1 inhibitor that plays a pivotal role in unraveling the complexities of glutamine metabolism in cancer. As a potent, selective, and non-competitive inhibitor, CB-839 allows researchers to precisely study the consequences of blocking GLS1 activity. Studies utilizing CB-839 have shown that inhibiting this enzyme can lead to a significant reduction in glutamine consumption and glutamate production in cancer cells. This metabolic disruption can hinder cancer cell growth and survival, making CB-839 a valuable pharmaceutical intermediate for drug development.

The impact of CB-839 extends to its antiproliferative and antitumor properties. In various cancer models, particularly triple-negative breast cancer (TNBC), CB-839 has demonstrated a strong capacity to inhibit tumor cell growth. Furthermore, its efficacy in combination with standard chemotherapies like Paclitaxel and Erlotinib is a key area of ongoing research. These combination strategies aim to exploit multiple vulnerabilities in cancer cells, leading to more robust therapeutic outcomes. For example, in non-small cell lung cancer (NSCLC), the combined approach can induce a metabolic crisis, thereby enhancing treatment efficacy.
