Galloflavin is primarily recognized for its role as a lactate dehydrogenase (LDH) inhibitor. It is used in research to study the metabolic pathways in cancer cells, as LDH is often upregulated in tumors, contributing to their growth and survival. By inhibiting LDH, galloflavin helps reduce lactate production, which is crucial for understanding and potentially disrupting the metabolic processes that support cancer progression. Additionally, it is utilized in studies focused on oxidative stress and energy metabolism, providing insights into cellular responses under various physiological and pathological conditions. Its application extends to exploring therapeutic strategies for diseases where altered metabolism plays a key role.
