Description
T56-LIMKi (T5601640) is a cell-active inhibitor of LIM kinase 2 (LIMK2) that reduces phosphorylation of the actin-regulatory protein cofilin. It inhibits proliferation of NF1-deficient MEFs and ST88-14, U87 and Panc-1 cells with reported IC50 values of 30, 18, 7 and 35 µM, respectively.
By suppressing the LIMK2–cofilin axis, T56-LIMKi is used to investigate cytoskeletal remodeling, proliferation and tumor-cell behavior. In Panc-1 xenograft studies it reduced tumor size together with intratumoral phospho-cofilin, providing an in vivo pharmacodynamic readout of LIMK pathway inhibition.
Key Features
