Cancer cells often exhibit a heightened reliance on glutamine, a phenomenon known as glutamine addiction. This metabolic dependency provides a critical vulnerability that researchers are actively exploiting for novel therapeutic strategies. Among the key players in this metabolic pathway is glutaminase (GLS), an enzyme responsible for converting glutamine to glutamate. Inhibiting GLS activity can therefore starve cancer cells of essential metabolic building blocks and energy, leading to cell death. In this context, CB-839 emerges as a significant compound for investigation.

CB-839 is a potent and selective non-competitive inhibitor of glutaminase GLS1. Its chemical structure and mode of action make it a valuable tool for understanding and targeting cancer metabolism. Research into CB-839 has demonstrated its effectiveness in preclinical models, particularly in triple-negative breast cancer (TNBC). Studies show that CB-839 can significantly reduce glutamine consumption and glutamate production in cancer cells, directly impacting their energetic and biosynthetic pathways. This makes CB-839 a crucial component in the development of new anti-cancer drugs.

The antiproliferative activity of CB-839 against various cancer cell lines is well-documented. In particular, its efficacy in TNBC models highlights its potential for treating aggressive forms of breast cancer. Furthermore, CB-839 has shown promise when used in combination with other chemotherapeutic agents, such as Paclitaxel and Erlotinib. These combination therapies can lead to enhanced anti-cancer effects, including reduced glucose and glutamine uptake and increased energetic stress within cancer cells. The ability of CB-839 to synergize with existing treatments underscores its versatility in the oncology research landscape.

Beyond breast cancer, research has also explored the impact of CB-839 on non-small cell lung cancer (NSCLC). By targeting the AMP-activated protein kinase (AMPK) pathway, CB-839 contributes to a metabolic crisis in EGFR mutant NSCLC xenografts, further solidifying its role in diverse cancer therapies. The oral bioavailability of CB-839 is another significant advantage, simplifying its administration and improving its potential for clinical translation. As a pharmaceutical intermediate, CB-839 is instrumental for suppliers and researchers looking to advance cancer treatment through metabolic intervention.
