pyridine fragment weakly inhibiting PKC-ι with IC50 = 424 μM. Driven by structure–activityrelationships and guided by docking hypothesis, the weakly bound fragment was eventually optimized into a potent inhibitor of PKC-ι (IC50= 270 nM). Through the course of the optimization, an intermediate compound was crystallized with the protein, and careful analysis of the X-ray crystalstructure revealed a unique
