Design, synthesis, and preliminary evaluation of new pyrrolidine derivatives as neuraminidase inhibitors.
A series of pyrrolidine derivatives were designed and synthesized in good yields starting from commercially available 4-hydroxy-L-proline using a suitable synthetic strategy. And their ability to inhibit neuraminidase was evaluated. These compounds showed potent inhibitory activity against influenza A (H3N2) neuraminidase. Within this series, four compounds, 6e, 9c, 9f and 10e, have the good potency (IC(50)=1.56 approximately 2.40microM) which is compared to the NA inhibitor oseltamivir (IC(50)=1.06microM), and could be used as lead compound in the future.
