  Diastereoselective Synthesis of cycloSaligenyl-Nucleosyl-Phosphotriesters

  摘要：

  AbstractA diastereoselective synthesis of cycloSal‐phosphotriesters (cycloSal=cycloSaligenyl) based on chiral auxiliaries has been developed that allows the synthesis of single diastereomers of the cycloSal‐pronucleotides. In previously described synthesis routes, the cycloSal‐compounds were always obtained as 1:1 diastereomeric mixtures that could be separated in only rare cases. However, it was shown that the diastereomers have different antiviral activity, toxicity, and hydrolysis stabilities. Here, first a chiral thiazoline derivative was used to prepare nonsubstituted and 5‐methyl‐cycloSal‐phosphotriesters in 48 and ≥95 % de (de=diastereomeric excess). However, this approach failed to give the important group of 3‐substituted cycloSal‐nucleotides. Therefore, two other chiral groups were discovered that allowed the synthesis of (RP)‐ and (SP)‐3‐methyl‐cycloSal‐phosphotriesters as well. The antiviral activity was found to be five‐ to 20‐fold different between the two individual diastereomers, which proved the importance of this approach.

  A new divergent approach towards carbocyclic α-, iso- and 3′-epi-nucleosides starting from enantiomerically pure (1S,2R)-2-benzyloxymethylcyclopent-3-enol (5) is described. In the key step, isomeric cyclopentanols were condensed with a N3-protected pyrimidine nucleobase using a modified Mitsunobu protocol. Moreover, the conversion into the cycloSal-pronucleotides and the effect of the orientation of the nucleobase on anti-HIV activity are reported.

  Carbocyclic analogues of the anti-HIV dideoxynucleoside 3′-azido-3′-deoxythymidine AZT (1) were synthesized. Starting from the enantiomerically pure carbocyclic 2′-deoxythymidine 2, four different carbocyclic AZT analogues 2,4–6 were prepared. Moreover, the nucleoside analogues were converted into their membrane-permeable cycloSal-phosphate triesters. All compounds were tested in vitro for their anti-HIV

  Methyl-substituted cycloSal-pronucleotides of d4TMP were synthesized with high diastereoselectivities in satisfying chemical yields. The individual diastereomers were tested against HIV-1 and HIV-2 infected wild-type CEM/0 and HIV-2 infected thymidine kinase deficient CEM cells. All diastereomers tested showed significant antiviral activity in CEM/0 and strong activity in CEM/TK– cell cultures. The

  合成的d4TMP的甲基取代的环Sal-前核苷酸具有很高的非对映选择性，可以满足化学收率。测试了各个非对映异构体针对HIV-1和HIV-2感染的野生型CEM / 0和HIV-2感染的胸苷激酶缺陷型CEM细胞的能力。所有测试的非对映异构体在CEM / 0中均表现出显着的抗病毒活性，在CEM / TK –细胞培养物中具有很强的活性。抗病毒活性强烈依赖于磷酸酯基团的手性和环Sal部分中甲基的位置。在CEM / TK中–细胞培养物中抗病毒效力的差异被发现为7至20倍。在水性磷酸盐缓冲液和CEM / 0细胞提取物中研究了每种非对映异构体的稳定性。发现半衰期有很大差异。基于通过反相HPLC获得的保留时间，进行了甲基取代的环Sal三酯的相对亲脂性的比较。获得的结果清楚地证实了环Sal-原核苷酸的非对映选择性合成的重要性。
