  Synthesis and Cytokine Modulation Properties of Pyrrolo[2,3-d]-4-pyrimidone Nucleosides

  摘要：

  A series of pyrrolo[2,3-d]pyrimidone nucleosides were synthesized and evaluated for their ability to enhance Type 2 cytokines and to suppress Type 1 cytokines in human T cells activated in vitro. Compounds 16b, 16c, 16d, 18c, and 19b induced substantial enhancement of IL-4 (a Type 2 cytokine) levels while three compounds (16b, 16c, and 16f) showed significant suppression of IFN gamma (a Type 1 cytokine) levels. The results revealed a strict structural requirement for the nucleoside-mediated enhancement of IL-4. Modifications of the ribofuranose moiety of the nucleosides either abolished or dramatically reduced the activity. Both the 5'-hydroxy and 5-carboxamidine are crucial for the activity. Of the few nucleoside analogues that demonstrated enhancement on Type 2 cytokine production, 7-(beta-D-ribofuranosyl)pyrrolo[2,3-d]-4-pyrimidone-5-carboxamidine (16c) showed a dramatic enhancement (>200%) of IL-4 levels and a significant enhancement (36%) of IL-5 levels. Moreover, this compound showed substantial suppression of the Type 1 cytokines, IFN gamma (42%), IL-2 (54%), and TNF alpha (55%). Similarly, compound 16b showed a substantial enhancement of IL-4 (46%) and suppression of IL-2 (35%), IFN gamma (30%), and TNF alpha (26%). To our knowledge, these are the first nucleoside analogues that induce a Type 2 cytokine bias in T cells. The cytokine modulation property of 16c and 16b merits the therapeutic evaluation of these compounds in treating diseases in which immunopathology is associated with polarized Type 1 cytokine responses.

  摘要：

  Treatment of purine, pyrimidine, and modified purine (antibiotic) ribonucleosides with 2-acetoxy-2-methylpropanoyl (alpha-acetoxyisobutyryl) bromide in acetonitrile gave mixtures of 2',3'-bromohydrin acetates with different O5' substituents. Significant amounts of 5'-unprotected (hydroxyl) bromo acetates were obtained in some cases, and formation of 2',3'-O-isopropylidene derivatives as minor byproducts was detected for the first time. Acid-catalyzed nucleophilic displacement of chloride by bromide occurred with 2-amino-6-chloropurine riboside, but no substitution of fluoride by bromide was detected with 6-amino-2-fluoropurine riboside. Treatment of the trans bromo acetate mixtures obtained from purine-type nucleosides with Dowex 1 x 2 (OH-) in methanol gave the 2',3'-anhydro (ribo epoxide) compounds. Radical-mediated hydrogenolytic debromination and deprotection gave 2'- and 3'-deoxynucleosides. Treatment of the bromo acetate mixtures with zinc-copper couple or acetic acid-activated zinc effected reductive elimination, and deprotection gave 2',3'-didehydro-2',3'-dideoxy compounds which were hydrogenated to give 2',3'-dideoxynucleosides. A number of these analogues have potent inhibitory activity against AIDS and hepatitis B viruses. New C-13 NMR data for several types of unsaturated-sugar nucleosides are tabulated. These procedures are directly applicable for the preparation of L-didehydro-dideoxy and L-dideoxy nucleoside analogues.
