TH-257 是一种有效的 LIMK1 和 LIMK2 抑制剂，对 LIMK1 和 LIMK2 的 IC50 值分别为 84 nM 和 39 nM，是 LIMK1 和 LIMK2 的化学探针。TH-257 是一种变构抑制剂，靶向由 αC 和 DFG-out 构象诱导的结合口袋。TH257 具有极好的选择性，在 1 μM 浓度下未观察到针对更广泛的激酶组的显着活性。

Background:

TH-257 is a potent inhibitor of LIMK1 and LIMK2 with IC50 values of 84 nM and 39 nM for LIMK1 and LIMK2, respectively, and it can be used as 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. TH257 is exquisitely selective and no significant activity against the wider kinome has been observed in the KINOMEscan assay at 1 μM[1].
