Serotype-specific structural differences in the protease-cofactor complexes of the dengue virus family.

With an estimated 40% of the world population at risk, dengue poses a significant threat to human health, especially in tropical and subtropical regions. Preventative and curative efforts, such as vaccine development and drug discovery, face additional challenges due to the occurrence of four antigenically distinct serotypes of the causative dengue virus (DEN1 to -4). Complex immune responses r...

New Binding Site Conformations of the Dengue Virus NS3 Protease Accessed by Molecular Dynamics Simulation

Dengue fever is caused by four distinct serotypes of the dengue virus (DENV1-4), and is estimated to affect over 500 million people every year. Presently, there are no vaccines or antiviral treatments for this disease. Among the possible targets to fight dengue fever is the viral NS3 protease (NS3PRO), which is in part responsible for viral processing and replication. It is now widely recognize...

Identification of covalent active site inhibitors of dengue virus protease

Dengue virus (DENV) protease is an attractive target for drug development; however, no compounds have reached clinical development to date. In this study, we utilized a potent West Nile virus protease inhibitor of the pyrazole ester derivative class as a chemical starting point for DENV protease drug development. Compound potency and selectivity for DENV protease were improved through structure...

Inhibition of tobacco etch virus protease activity by detergents.

Affinity tags such as polyhistidine greatly facilitate recombinant protein production. The solubility of integral membrane proteins is maintained by the formation of protein-detergent complexes (PDCs), with detergent present at concentration above its critical micelle concentration (CMC). Removal of the affinity tag necessitates inclusion of an engineered protease cleavage site. A commonly util...

Dengue Virus NS2B/NS3 Protease Inhibitors Exploiting the Prime Side.

The mosquito-transmitted dengue virus (DENV) infects millions of people in tropical and subtropical regions. Maturation of DENV particles requires proper cleavage of the viral polyprotein, including processing of 8 of the 13 substrate cleavage sites by dengue virus NS2B/NS3 protease. With no available direct-acting antiviral targeting DENV, NS2/NS3 protease is a promising target for inhibitor d...
