Structural optimization to translate enzyme inhibitory activity to cellular cytotoxicity yielded compound 16c, a moderate enzyme inhibitor (IC50 = 27.3 µM) with selective toxicity to hepatitis C virus 1b replicon-containing Ava5 cells (EC50 = 18.0 µM). Binding experiments indicated that 16c (Kd = 1.25 µM) not only competed with fluorescein-labeled GTP for NS5B binding, but also displaced bound GTP from the polymerase active site.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Hepatitis C virus NS5B polymerase ?,?-diketo acid bioisostere isoindole-1,3-dione</Keywords> <URLs> <Abstract>https://aaspjournal.org/ubijournal-v1copy/journals/abstract.php?article_id=5945&title=Isoindole-1,3-dione-based __ampersandsignalpha;,__ampersandsigngamma;-diketo acid bioisosteres as hepatitis C virus NS5B polymerase inhibitors</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References/> </References> </Journal> </Article> </ArticleSet>
