摘要: DYRKs (dual specificity, tyrosine phosphorylation regulated kinases) and CLKs (cdc2-like are implicated in the onset development of Alzheimer’s disease Down syndrome. The marine sponge alkaloid leucettamine B was recently identified as an inhibitor DYRKs/CLKs. Synthesis analogues (leucettines) led to optimized product, leucettine L41. Leucettines were cocrystallized with DYRK1A, DYRK2, CLK3, PIM1, GSK-3β. selectivity L41 studied by activity interaction assays recombinant kinases affinity chromatography competition assays. These approaches revealed unexpected potential secondary targets such CK2, SLK, lipid kinase PIKfyve/Vac14/Fig4. displayed neuroprotective effects on glutamate-induced HT22 cell death. also reduced amyloid precursor protein-induced death cultured rat brain slices. unusual multitarget leucettines may account for their effects. This family inhibitors dese...
