  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.

  Tosylation/mesylation of 4-hydroxy-3-nitro-2-pyridinones as an activation step in the construction of dihydropyrido[3,4-b] benzo[f][1,4]thiazepin-1-one based anti-HIV agents

  摘要：

  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.

  日期：1997.9

  In order to obtain 4-C-alkylated pyridin-2(1H)-ones, two strategies were studied: nucleophilic substitution of 4-chloro-3-nitropyridinone derivatives which essentially failed and lithiations of 2-methoxy-3-pivaloylaminopyridines which gave the expected products.

  为了获得4-C-烷基化的吡啶-2（1 H）-1 ，研究了两种策略：基本上失效的4-氯-3-硝基吡啶酮衍生物的亲核取代和2-甲氧基-3-新戊酰氨基吡啶的锂化预期的产品。
