文摘

There are currently three HIV-1 integrase (IN) strand transfer inhibitors (INSTIs) approved by the FDA for the treatment of AIDS. However, the emergence of drug-resistant mutants emphasizes the need to develop additional agents that have improved efficacies against the existent resistant mutants. As reported herein, we modified our recently disclosed 1-hydroxy-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxamides IN inhibitors to develop compounds that have improved efficacies against recombinant IN in biochemical assays. These new compounds show single-digit nanomolar antiviral potencies against HIV vectors that carry wild-type (WT) IN in a single round replication assay and have improved potency against vectors harboring the major forms of drug resistant IN mutants. These compounds also have low toxicity for cultured cells, which in several cases, results in selectivity indices (CC₅₀/EC₅₀) of greater than 10000. The compounds have the potential, with additional structural modifications, to yield clinical agents that are effective against the known strains of resistant viruses.
