  A New Series of Pyridinone Derivatives as Potent Non-Nucleoside Human Immunodeficiency Virus Type 1 Specific Reverse Transcriptase Inhibitors

  摘要：

  4-(Arylthio)-pyridin-2(1H)-ones variously substituted in their 3-, 5-, and 6-positions have been synthesized as a new series of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT)-pyridinone hybrid molecules. Biological studies revealed that some of them show potent HIV-1 specific reverse transcriptase inhibitory properties. Compounds 16 and 7c, the most active ones, inhibit the replication of HIV-1 at 3 and 6 nM, respectively.

  日期：2005.4

  Reaction of 4-hydroxy-3-nitropyridinone 8 with TsCl and MsCl, respectively, resulted in rapid and quantitative formation of ditosylate 13 and dimesylate 16. Through chemoselective reaction of 16 with thiophenol 17 the key 4-thioaryl substituted intermediate 18 was obtained in 78% yield. This compound was efficiently converted to the target tricyclic products 4a and b. Compound 4a, in particular, is a potent inhibitor in vitro (IC50 = 2 nM) of wild type HIV-1 replication.
