isoquinoline-1,3-dione as a viable chemotype for selectivelyinhibiting TDP2. The initial hit compound 43 was identified by screening our in-house collection of synthetic compounds. Further structure–activity relationship (SAR) studies identified numerous analogues inhibiting TDP2 in low micromolar range without appreciable inhibition against the homologous TDP1 at the highest testing concentration

2-hydroxyisoquinoline-1,3-diones inhibit the strand transfer of HIV integrase (IN) and the reverse-transcriptase-associated ribonuclease H (RNH). HepatitisCvirus (HCV) NS5B polymerase shares a similar active site fold to RNH and IN, suggesting that N-hydroxyimides could be useful inhibitor scaffolds of HCV via targeting the NS5B. Herein we describe the design, chemical synthesis, replicon and biochemical
Design, Synthesis, and Biological Evaluation of a Series of 2-Hydroxyisoquinoline-1,3(2<i>H</i>,4<i>H</i>)-diones as Dual Inhibitors of Human Immunodeficiency Virus Type 1 Integrase and the Reverse Transcriptase RNase H Domain
We report herein the synthesis of a series of 19 2-hydroxyisoquinoline-1,3(2H,4H)-dione derivatives variously substituted at position 7 aimed at inhibiting selectively two-metal ion catalytic active sites. The compounds were tested against HIV-1 reverse transcriptase (RT) polymerase, HIV-1 RT ribonuclease H (RNase H), and HIV-1 integrase (IN). Most compounds displayed poor inhibition of RT polymerase
The present invention relates to a series of Isoquinolone derivatives which are suitable to treat infections with viruses belonging to the family of the Flaviviridae and more preferably infections with Hepatitis C virus (HCV). The present invention also relates to Isoquinolone compounds for use as a medicine for the prevention or treatment of viral infections, preferably infections with viruses belonging to the family of the Flaviviridae.
