MCT1-IN-2 is primarily utilized in research settings to study the role of monocarboxylate transporter 1 (MCT1) in cellular metabolism. It is a potent inhibitor of MCT1, which is involved in the transport of lactate, pyruvate, and other monocarboxylates across cell membranes. By blocking MCT1, this compound helps researchers investigate the metabolic dependencies of cancer cells, as many tumors rely on lactate transport for energy production and survival. Additionally, MCT1-IN-2 is used to explore potential therapeutic strategies targeting metabolic pathways in diseases such as cancer and metabolic disorders. Its application extends to understanding the interplay between metabolism and immune cell function, providing insights into immune modulation and tumor microenvironment dynamics.
