Based on 2-(4-phenoxybenzoyl)-5-hydroxyindole (2), a novel structural class of CaMKII inhibitors were synthesized and further optimized. The strong acidity of the hydroxyl group and the lipophilic group at the 4 and 6-positions were found to be necessary for strong CaMKII inhibition. Compound 25 was identified as a promising compound with 50-fold more potent inhibitory activity for CaMKII than 2. Compound 25 also showed high selectivity for CaMKII over off-target kinases.
