Used as a potent inhibitor of protein arginine methyltransferase 1 (PRMT1), 2-D08 is widely applied in biochemical and pharmacological research to study cellular processes regulated by arginine methylation. It helps modulate epigenetic signaling pathways, making it a valuable tool in cancer research, particularly for investigating tumor growth and gene expression control. Additionally, 2-D08 is employed to explore inflammatory responses and immune regulation due to its role in suppressing certain pro-inflammatory mediators. Its application extends to neuroscience research, where it aids in understanding neurodegenerative mechanisms linked to aberrant methylation.
