POM 1 is a chemical compound known as a potent and selective inhibitor of the enzyme ecto-apyrase (CD39), which is involved in the hydrolysis of ATP to ADP and AMP. In research, POM 1 is used to study the purinergic signaling pathway, which plays a role in various physiological processes. By inhibiting CD39 activity, POM 1 allows scientists to investigate the consequences of altered extracellular nucleotide levels and their impact on cellular function and communication. The use of POM 1 in research has contributed to a better understanding of the pathophysiological roles of CD39 in disease models and has provided insights into the regulation of the extracellular nucleotide environment. Research involving POM 1 is often directed toward elucidating the mechanisms by which purinergic signaling influences the progression of diseases and the identification of potential targets for new research tools.
