reverse transcriptase (HIV-1 RT) is a major target for currently approved anti-HIV drugs. These drugs are divided into two classes: nucleoside and non-nucleoside reverse transcriptase inhibitors (NRTIs and NNRTIs). This study illustrates the synthesis and biochemical evaluation of a novel bifunctional RT inhibitor utilizing d4T (NRTI) and a TMC-derivative (a diarylpyrimidine NNRTI) linked via a poly(ethylene

The present invention relates to compounds, in particular, dual antagonists comprising a nucleoside reverse transcriptase inhibitor (NRTI) or a nucleoside competititive reverse transcriptase inhibitor and a non-nucleoside reverse transcriptase inhibitor (NNRTI), linked together using a chemical linker, which may be used to inhibit HIV (HIV-1) reverse transcriptase and in the treatment of HIV infections, more severe cases of HIV infections, including ARC and AIDS, including reducing the likelihood of these infections and disease states.

In a continuing study of potent bifunctional anti-HIV agents, we rationally designed a novel chimeric inhibitor utilizing thymidine (THY) and a TMC derivative (a diarylpyrimidine NNRTI) linked via a polymethylene linker (ALK). The nucleoside, 5'-hydrogen-phosphonate (H-phosphonate), and S'-triphosphate forms of this chimeric inhibitor (THY-ALK-TMC) were synthesized and the antiviral activity profiles were evaluated at the enzyme and cellular level. The nucleoside triphosphate (11) and the H-phosphonate (10) derivatives inhibited RT polymerization with an IC50 value of 6.0 and 4.3 nM, respectively. Additionally, chimeric nucleoside (9) and H-phosphonate (10) derivatives reduced HIV replication in a cell-based assay with low nanomolar antiviral potencies.
