ABSTRACT

A series of potent novel 8-hydroxy-3,4-dihydropyrrolo[1,2-a]pyrazine-1(2H)-one HIV-1 integrase inhibitors was identified. These compounds inhibited the strand transfer process of HIV-1 integrase and viral replication in cells. Compound 12 is active against replication of HIV-1 in cell culture with a CIC(95) of 0.31microM. Further SAR exploration led to the preparation of pseudosymmetrical tricyclic pyrrolopyrazine inhibitors 23 and 24 with further improvement in antiviral activity.
