WH-4-023

Description

WH-4-23 (837422-57-8) is a potent and selective inhibitor of Src family kinases Lck and Src, IC50=2 and 6 nM respectively.1,2 Also inhibits SIK, IC50=10, 22 and 60 nM for SIK 1, 2 and 3 respectively.3 May be used along with PD-325901 and CHIR-99021 to support self-renewal of na?ve human embryonic stem cells.4

The Uses of WH-4-023

WH-4-023 is a potent and selective dual lymphocyte-specific kinase (Lck) inhibitor.

Definition

ChEBI: N-(2,4-dimethoxyphenyl)-N-[2-[4-(4-methyl-1-piperazinyl)anilino]-4-pyrimidinyl]carbamic acid (2,6-dimethylphenyl) ester is a member of piperazines.

Biochem/physiol Actions

WH-4-023 (KIN112) is a potent and selective inihbitor of the tyrosine kinases Lck and Src with IC50 values of 2 nM for Lck and 6 nM for Src. WH-4-023 is a somewhat less potent inhibitor of salt-inducible kinases (SIKs) with IC50 values of 10, 22 and 60 nM for SIK 1, 2 and 3 respectively. WH-4-023 was found to support self-renewal of naive human embryonic stem cells, in particular in combination with PD 0325901 (PZ0162), CHIR99021 (SML1046), and SB-590885 (SML0501).
