The increasing efficiency of HAART has helped to transform HIV/AIDS into a chronic disease. Still, resistance and drug-drug interactions warrant the development of new anti-HIV agents. We previously discovered hit 6, active against HIV-1 replication and targeting RNase H in vitro. Because of its diketo-acid moiety, we speculated that this chemotype could serve to develop dual inhibitors of both RNase H and integrase. Here, we describe a new series of 1-benzyl-pyrrolyl diketohexenoic derivatives, 7a-y and 8a-y, synthesized following a parallel solution-phase approach. Those 50 analogues have been tested on recombinant enzymes (RNase H and integrase) and in cell-based assays. Approximately half (22) exibited inhibition of HIV replication. Compounds 7b, 7u, and 8g were the most active against the RNase H activity of reverse-transcriptase, with IC50 values of 3, 3, and 2.5 μM, respectively. Compound 8g was also the most potent integrase inhibitor with an IC50 value of 26 nM.

The HIV-1 integrase (IN) and reverse transcriptase (RT) are essential enzymes in the virus cycle. RT is crucial for the retrotranscription of the RNA viral genome, while IN is involved in the insertion in host chromosome of the proviral double strand DNA produced by RT. This enzyme has two associated functions: the RNA- and DNA-dependent DNA polymerase (RDDP and DDDP) and the ribonuclease H (RNase H). The RNase H function catalyzes the selective hydrolysis of the RNA strand of the RNA:DNA heteroduplex replication intermediate. Since the discovery that catalytic cores of both HIV-1 RNase H and IN are folded in a very similar way, have very similar active site geometries, and show the same DDE triad absolutely required for catalytic activity, some researches were devoted to study IN and RNase H dual inhibitor. Our decennial interest in design and synthesis of IN inhibitors led us to study the activity of our compounds also on RNase H activity. The results of the activities showed by pyrrolyl and quinolonyl diketo acids are reported and discussed.
