lin28

Lin28 1632 is an inhibitor of RNA binding protein Lin28. It promotes mESC differentiation. Lin281632 is also bromodomain inhibitor.

LIN28 inhibitor LI71 is a potent and cell-permeable compound that effectively abolishes LIN28-mediated oligouridylation, with an IC50 of 7 µM (micromolar).

LIN28 inhibitor LI71 enantiomer, the enantiomer of LIN28 inhibitor LI71，exhibits reduced activity compared to its parent compound. LIN28 inhibitor LI71 is a highly potent and cell-permeable inhibitor of LIN28, effectively blocking LIN28-mediated oligouridylation with an IC50 of 7 uM.

LIN28-IN-1 (compound 5) is a selective inhibitor targeting the RNA-binding protein LIN28, binding specifically to its cold shock domain (CSD). This compound interrupts the LIN28-let-7 miRNA interaction with an IC50 of 5.4 μM, mitigating LIN28's adverse effects on epigenetic gene control. LIN28-IN-1 also exhibits significant anti-proliferative activity against LIN28-expressing JAR cancer cells, with an IC50 value of 6.4 μM [1].

Lin28-let-7a antagonist 1, with an IC50 of 4.03 μM for Lin28A-let-7a-1 interaction,and shows a clear antagonistic effect against the Lin28-let-7a interaction.

O4I2 is an effective Oct3/4 inducer in various human cell lines including human fibroblasts.

GG-43 is a potent inhibitor of LIN28. The IC50 value of GG-43 against human LIN28A is 4 μM [1].
