Ketones as Building Blocks for Dynamic Combinatorial Libraries:  Highly Active Neuraminidase Inhibitors Generated via Selection Pressure of the Biological Target

New and potent inhibitors of neuraminidase, a key enzyme in the influenza virus activity, have been discovered in dynamic combinatorial libraries based on ketones and amines as building blocks. Selective synthesis of a number of inhibitors among multiple theoretically possible combinations of building blocks is driven by the presence of the target enzyme.
