N-3 Hydroxylation of Pyrimidine-2,4-diones Yields Dual Inhibitors of HIV Reverse Transcriptase and Integrase
摘要:
A new molecular scaffold featuring an N-hydroxyimide functionality and capable of inhibiting both reverse transcriptase (RT) and integrase (IN) of human immunodeficiency virus (HIV) was rationally designed based on 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT) non-nucleoside RT inhibitors (NNRTIs). The design involves a minimal 3-N hydroxylation of the pyrimidine ring of HEPT compound to yield a chelating triad which, along with the existing benzyl group, appeared to satisfy major structural requirements for IN binding. In the mean time, this chemical modification did not severely compromise the compound's ability to inhibit RT. A preliminary structure-activity relationship (SAR) study reveals that this N-3 OH is essential for IN inhibition and that the benzyl group on N-1 side chain is more important for IN binding than the one on C-6.

Integrase (IN) represents a clinically validated target for the development of antivirals against human immunodeficiency virus (HIV). Inhibitors with a novel structure core are essential for combating resistance associated with known IN inhibitors (IN Is). We have previously disclosed a novel dual inhibitor scaffold of HIV IN and reverse transcriptase (RT). Here we report the complete structure activity relationship (SAR), molecular modeling, and resistance profile of this inhibitor type on IN inhibition. These studies support an antiviral mechanism of dual inhibition against both IN and RT and validate 3-hydroxypyrimidine-2,4-diones as an IN inhibitor scaffold.

The invention provides antiviral compounds that can be used in therapy against human immunodeficiency virus (HIV) and hepatitis C virus (HCV). Compounds of the invention can be dual targeted inhibitors of HIV, inhibiting both the reverse transcriptase and the integrase enzyme systems, thus increasing the barrier to development of viral resistance in patients. Prodrugs of the inventive antiviral compounds are also provided. Compounds of the invention can be used to treat HCV secondary infections in HIV-afflicted patients, reducing the need for administration of drug cocktails containing multiple, potentially conflicting, medicinal compounds. Methods of synthesis of the compounds and methods of treatment using the compounds are also provided.
