Structure of HCV NS5B Bound to an Anthranilic Acid InhibitorStructure of HCV NS5B Bound to an Anthranilic Acid Inhibitor
Structural highlights
FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedA series of potent anthranilic acid-based inhibitors of the hepatitis C NS5B polymerase has been identified. The inhibitors bind to a site on NS5B between the thumb and palm regions adjacent to the active site as determined by X-ray crystallography of the enzyme-inhibitor complex. Guided by both molecular modeling and traditional SAR, the enzyme activity of the initial hit was improved by approximately 100-fold, yielding a series of potent and selective NS5B inhibitors with IC50 values as low as 10 nM. These compounds were also inhibitors of the HCV replicon in cultured HUH7 cells. Identification of anthranilic acid derivatives as a novel class of allosteric inhibitors of hepatitis C NS5B polymerase.,Nittoli T, Curran K, Insaf S, DiGrandi M, Orlowski M, Chopra R, Agarwal A, Howe AY, Prashad A, Floyd MB, Johnson B, Sutherland A, Wheless K, Feld B, O'Connell J, Mansour TS, Bloom J J Med Chem. 2007 May 3;50(9):2108-16.
