  Synthesis and Anti-HIV-1 Activity of a Series of 1-Alkoxy-5-alkyl-6-(arylthio)uracils

  摘要：

  A series of 1-alkoxy-5-alkyl-6-(arylthio)uracils was synthesized and tested for their ability to inhibit HIV-1 replication. Treatment of 2-alkyl-3,3-bis(methylthio)acryloyl chlorides (5a-e) with AgOCN in benzene followed by reaction of the resulting isocyanates 6a-e with an appropriate alkoxyamine gave N-alkoxy-N'-((2-alkyl-3,3-bis(methylthio (10a-z) in good to excellent yields. Cyclization of 10a-z in AcOH containing st catalytic amount of p-TsOH produced 1-alkaxy-5-alkyl-6-(methylthio)uracils (11a-z). Oxidation of 11a-z with 3-chloroperoxybenzoic acid in CH2Cl2 resulted in high yields of 1-alkoxy-5-alkyl-6-(methylsulfonyl)uracils (12a-x and 12z) and 1-(benzyloxy)-6-(methylsulfinyl)thymine (12y), which were subsequently reacted with an appropriate arenethiol in ethanolic NaOH solution to afford 1-alkoxy-5-alkyl-6-(arylthio)uracils (14-49). Substitution at the 3- and 5-positions of the C-6-(phenylthio) ring by two methyl groups significantly increased its original anti-HIV-l activity (EC50: 6-((3,5-dimethylphenyl)thio)-5-isopropyl-1-propoxyuracil (18), 0.064 mu M; 6-((3,5-dimethylphenyl)thio)-1-(3-hydroxypropoxy)-5-isopropyluracil (23), 0.19 mu M). Among the various alkoxy substituents at the N-1, the propoxy group was the most beneficial for improving the anti-HIV-1 activity. The 1-propoxy derivative 18 proved to be the most potent inhibitor of HIV-1 replication, followed by the 1-(3-hydroxypropoxy) derivative 23. Introduction of an isopropyl group at C-5 of the uracil base also remarkably enhanced the activity. When compound 18 was incubated with a rat liver homogenate preparation, no metabolite was observed, thus confirming the metabolic stability of the N-O bond in these 1-alkoxyuracils.
