Description:

WARNING: This product is for research use only, not for human or veterinary use.

LIN28 inhibitor LI71 is a potent, cell-permeable inhibitor of LIN28 that abolishes LIN28-mediated oligouridylation. LIN28 inhibitor LI71 binds the cold shock domain to suppress LIN28's activity against let-7 in leukemia cells and embryonic stem cells.

Product Data
Biological target:
LIN28 inhibitor LI71 is a potent and cell-permeable LIN28 inhibitor, which abolishes LIN28-mediated oligouridylation with an IC50 of 7 uM.
In vitro activity:
LI71 could significantly reduce the relative Renilla luciferase activity in cells expressing LIN28A and LIN28B at 50–100 μM (Figures 6B and 6C). Together, these results demonstrate that, consistent with in vitro data, LI71 inhibits LIN28’s activity on let-7 micro-RNAs in LIN28-dependent cancer and embryonic stem cells.
