Abstract
A series of methionine-proline dipeptide derivatives and their analogues were designed, synthesized and assayed against the serotype 2 dengue virus NS2B-NS3 protease, and methionine-proline anilides 1 and 2 were found to be the most active DENV 2 NS2B-NS3 competitive inhibitors with Ki values of 4.9 and 10.5 μM. The structure and activity relationship and the molecular docking revealed that L-proline, L-methionine and p-nitroaniline in 1 and 2 are the important characters in blocking the active site of NS2B-NS3 protease. Our current results suggest that the title dipeptidic scaffold represents a promising structural core to discover a new class of active NS2B-NS3 competitive inhibitors.Entities:
