  10-Hydroxy-7,8-dihydropyrazino[1′,2′:1,5]pyrrolo[2,3-d]pyridazine-1,9(2H,6H)-diones: Potent, orally bioavailable HIV-1 integrase strand-transfer inhibitors with activity against integrase mutants

  摘要：

  A series of 10-hydroxy-7,8-dihydropyrazino[1',2':1,5]pyrrolo[ 2,3-d]pyridazine-1,9(2H,6H)-diones was synthesized and tested for their inhibition of HIV-1 replication in cell culture. Structure-activity studies indicated that high antiviral potency against wild-type virus as well as viruses containing integrase mutations that confer resistance to three different structural classes of integrase inhibitors could be achieved by incorporation of small aliphatic groups at certain positions on the core template. An optimal compound from this study, 16, inhibits integrase strand-transfer activity with an IC50 value of <= 10 nM, inhibits HIV-1 replication in cell culture with an IC95 value of 35 nM in the presence of 50% normal human serum, and displays modest pharmacokinetic properties in rats (iv t(1/2) = 5.3 h, F = 17%).

  Hydroxy-substituted pyrazinopyrrolopyridazine dione compounds are inhibitors of HIV integrase and inhibitors of HIV replication. In one embodiment, the dione compounds are of Formula (I) wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 are defined herein. The compounds are useful in the prevention and treatment of infection by HIV and in the prevention, delay in the onset, and treatment of AIDS. The compounds are employed against HIV infection and AIDS as compounds per se or in the form of pharmaceutically acceptable salts. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antivirals, immunomodulators, antibiotics or vaccines.
