Identification and In Silico Binding Study of a Highly Potent DENV NS2B-NS3 Covalent Inhibitor.

ABSTRACT: Dengue virus (DENV), an arthropod-borne flavivirus, has developed rapidly in the past few decades and becoming the most widespread arbovirus in the world. The vital role of NS2B-NS3 in virus replication and maturation of viral proteins makes it the most promising target for anti-DENV drug discovery. In the current work, a potent NS2B-NS3 covalent inhibitor 23 (IC₅₀ = 6.0 nM, k _inac/K _i = 1581 M^-1 s^-1) was discovered through the chemical modification of a published covalent inhibitor 1 (IC₅₀ = 500 nM, k _inac/K _i = 156.1 M^-1 s^-1), followed by in vitro assay.
