  A Parallel Synthesis Approach to the Identification of Novel Diheteroarylamide-Based Compounds Blocking HIV Replication: Potential Inhibitors of HIV-1 Pre-mRNA Alternative Splicing

  摘要：

  A 256-compound library was evaluated in an anti-HIV screen to identify structural "mimics" of the fused tetracyclic indole compound 1 (IDC16) that conserve its anti-HIV activity without associated cytotoxicity. Four diheteroarylamide-type compounds, containing a common 5-nitroisobenzothiazole motif, were identified as active. In subsequent screens, the most potent compound 9 (1C8) was active against wild-type HIV-1(IIIB) (subtype B, X4-tropic) and HIV-1 97USSN54 (subtype A, R5-tropic) with EC50's of 0.6 and 0.9 mu M, respectively. Compound 9 also inhibited HIV strains resistant to drugs targeting HIV reverse transcriptase, protease, integrase, and coreceptor CCRS with EC50's ranging from 0.9 to 1.5 mu M. The CC50 value obtained in a cytotoxicity assay for compound 9 was >100 mu M, corresponding to a therapeutic index (CC50/EC50) of approximately 100. Further comparison studies revealed that, whereas the anti-HIV activity for compound 9 and the parent molecule 1 are similar, the cytotoxic effect for compound 9 was, as planned, markedly suppressed.

  representative 4-pyridinone-based carboxylic acid were sufficiently activated to react efficiently in amide coupling reactions with the amide anion generated in situ from the N-trimethylsilyl derivative of different weakly nucleophilic heteroarylamines. In acetonitrile as solvent, the precipitated diheteroarylamide products were isolated in pure form by vacuum filtration. This simple amide bond forming protocol
