Description: TH-263 is an inactive analog control for the type III allosteric LIM-kinase (LIMK) inhibitors TH-257, TH-255 and TH-251. LIM kinases belong to the family of cytoplasmic tyrosine-like kinases with dual specificity (serine/threonine and tyrosine). However, known LIMK substrate are usually phosphorylated at serine and threonine residues LIM kinases comprises LIM kinase 1 (LIMK1) and LIM kinase 2 (LIMK2) which show 50% sequence identity in human. Both LIMK1 and LIMK2 present with a unique domain organization containing two N-terminal LIM domains, a PDZ domain, a proline/serine-rich domain and a C-terminal kinase domain.

Additional Information

Note: Sigma's TH-263 (cas3SML2276) has CAS#1004044-80-7, which is a wrong structure.

TH-257 is a chemical probe for LIMK1 and LIMK2. TH-257 is an allosteric inhibitor targeting a binding pocket induced by an αC and DFG-out conformation. It potently inhibits cofilin phosphorylation with an IC50 of 84 nM for LIMK1 and 39 nM for LIMK2 in a RapidFire MS assay. TH257 is exquisitely selective and no significant activity against the wider kinome has been observed in the KINOMEscan assay (Dx) at 1 μM (IC50 >> 50 % inhibition). In a life cell NanoBRET assay (Promega) TH257 has an IC50 of 250 nM against ectopically expressed full-length LIMK1 and 150 nM LIMK2, respectively.
