  Derivatives of 1-(2-Deoxy-2-fluoro-β-D-arabinofuranosyl)-5-phenyluracil and 5-Benzyluracil. Synthesis and Biological Properties

  摘要：

  A number of 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)uracil and -cytosine nucleosides substituted at the 5 position with a nitrophenyl or nitrobenzyl group were synthesized from 5-phenyl- and 5-benzyluracil via condensation of the fluorinated sugar, followed by nitration. The corresponding amino analogues were also prepared by reduction of the nitro nucleosides. The uracil nucleosides were converted into the corresponding cytosine nucleosides by way of the triazole intermediates. None of these nucleosides exhibited significant activity against herpes simplex virus type 1 in Vero cells. However, cytosine nucleosides containing the o-nitrophenyl, p-nitrophenyl, p-nitrobenzyl or p-aminobenzyl substituent were found to be toxic (even at 1 mu M) to uninfected Vero cells, although they were essentially nontoxic in HL-60 cells. The 5'-monophosphates of the uracil nucleosides were inhibitors of the reaction catalyzed by purified Ehrlich ascites carcinoma thymidylate synthase, the 5-phenyluracil nucleotides causing a strong inhibition, competitive vs dUMP, described by the K-i value of 0.01 mu M.

• Synthesis of 1-[[2-hydroxy-1-(hydroxymethyl)ethoxy]methyl]-5-benzyluracil and its amino analog new potent uridine phosphorylase inhibitors with high water solubility

  Acyclic nucleosides 1-[[2-hydroxy-1-(hydroxymethyl)ethoxy] methyl]-5-benzyluracil (DHPBU) (1) and 1-[[2-hydroxy-1-(aminomethyl)ethoxy]methyl]-5-benzyluracil (AHPBU) (2) have been synthesized by direct coupling of bis(trimethylsilyl)-5-benzyluracil with the corresponding chloromethyl ether, followed by removal of the blocking groups. Compounds 1 and 2 were found to be very potent inhibitors of uridine

  无环核苷1-[[[2-羟基-1-（羟甲基）乙氧基]甲基] -5-苄基尿嘧啶（DHPBU）（1）和1-[[2-羟基-1-（氨基甲基）乙氧基]甲基] -5-通过将双（三甲基甲硅烷基）-5-苄基尿嘧啶与相应的氯甲基醚直接偶联，然后除去保护基团，已经合成了苄基尿嘧啶（AHPBU）（2）。发现化合物1和2是从肉瘤180细胞分离的尿苷磷酸化酶的非常有效的抑制剂，Ki值分别为0.098和0.020microM，并且对肉瘤180宿主细胞没有表现出明显的细胞毒性。此外，1和2已显示出极好的水溶性（分别在25摄氏度时为270和大于300 mg / mL），这对于通常限制特定化合物作为化学治疗剂的用途的制剂而言至关重要。

  1′-Halogenomethyl, 1′-azidomethyl and 1′-disubstituted aminomethyl derivatives of BAU (5-benzylacyclouridine) and BBAU (5-benzyloxybenzylacyclouridine) were synthesized in the course of our studies of benzylacyclouridines. Two new and more convenient preparations of the previously known aminomethyl-and hydroxymethyl-parent compounds of these two series, AM-BAU, AM-BBAU and HM-BBAU are also reported
