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 CIC95 of 0.31 mu M. Further SAR exploration led to the preparation of pseudosymmetrical tricyclic pyrrolopyrazine inhibitors 23 and 24 with further improvement in antiviral activity. (c) 2007 Elsevier Ltd.
