MRL-SYKi
Based on 1 Customer Validation
MRL-SYKi is a chemical probe for gain-of-function variants of spleen tyrosine kinase (SYK). MRL-SYKi reduces the catalytic activity of SYKS550Y, SYKS550F and SYKP342T, and downregulates the phosphorylation level of SYKS550Y. MRL-SYKi serves as a template for developing NanoBRET tracers targeting SYK, enabling NanoBRET cellular target engagement assays for gain-of-function variants of SYK. MRL-SYKi is applicable to research related to inflammatory and immune diseases.

Biological Activity
MRL-SYKi potently inhibits purified SYK protein in cell-free enzymatic assays, with an IC50 of 30 nM[1].
MRL-SYKi (20 μM) binds to all tested NL-tagged SYK variants in digitonin-permeabilized HEK293 cells, with the highest potency against SYKS550Y (IC50 = 2.1 nM) and the lowest potency against SYKM450I (IC50 = 29 nM)[1].
MRL-SYKi (1-10 μM; 2 h) directly binds to NL-tagged SYKS550Y, SYKS550F, and SYKP342T in intact living HEK293 cells, with the highest potency against SYKS550Y (IC50 = 65 nM) and the lowest potency against SYKP342T (IC50 = 410 nM)[1].
MRL-SYKi (1.75-30 μM; 30 min) binds to NL-tagged SYK (WT) in digitonin-permeabilized HEK293 cells and increases its thermal stability, with a maximum ΔTm of 3.5 °C at the concentration of 30 μM[1].
MRL-SYKi (30 min) potently inhibits the catalytic activity of purified SYKS550F (IC50 = 63 nM) and SYKP342T (IC50 = 95 nM) in cell-free kinase activity assays[1].
MRL-SYKi (100 nM-10 μM; 20 h) reduces the phosphorylation level of SYKS550Y at Y525/526 in SW480 cells stably expressing SYKS550Y[1].
