The LIN28 inhibitor LI71 enantiomer is primarily used in research focused on cancer therapy and stem cell biology. It targets the LIN28 protein, which is known to play a critical role in cell proliferation and tumorigenesis. By inhibiting LIN28, this compound helps in reducing the growth of cancer cells, particularly in cancers where LIN28 is overexpressed, such as certain types of breast, ovarian, and liver cancers. Additionally, it is utilized in studies aimed at understanding the mechanisms of cellular reprogramming and differentiation, offering insights into regenerative medicine and potential treatments for diseases involving tissue repair and regeneration. Its application in these fields underscores its importance in advancing therapeutic strategies and biomedical research.
