Perfect match : An organoruthenium complex with at most a low picomolar binding constant for glycogen synthase kinases 3 is reported, whose binding to the ATP‐binding site has been analyzed by X‐ray crystallography. The complex, ( R Ru )‐ NP549 , is one of the most potent protein kinase inhibitors reported to date, almost four orders of magnitude more potent than the related natural product staurosporine.
