Description	Leucettinib-92 (compound 92) is an inhibitor of DYRK/CLK kinase, The IC₅₀s are 147 nM (CLK1), 39 nM (CLK2), 5.2 nM (CLK4), 0.8 μM (CLK3), 124 nM (DYRK1A), 204 nM (DYRK1B), 0.16 μM (DYRK2), respectively. 1.0 μM (DYRK3), 0.52 μM (DYRK4), 2.78 μM (GSK3)^[1].
IC₅₀ & Target	IC50: 147 nM (CLK1), 39 nM (CLK2), 5.2 nM (CLK4), 0.8 μM (CLK3), 124 nM (DYRK1A), 204 nM (DYRK1B), 0.16 μM (DYRK2), 1.0 μM (DYRK3), 0.52 μM (DYRK4), 2.78 μM (GSK3)^[1]
In Vitro	Leucettinib-92 (0.1-10 μM; 3 min) binds to DYRK1A in SH-SY5Y cells and induces it to stabilize until melting temperature above 52°C. Leucettinib-92 (1 μM) inhibits phosphorylation of two DYRK1A substrates (Thr212-Tau and Thr286-cyclin D1)^[1]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
