  Synthesis and Antiviral Activity of Certain 5‘-Modified Analogs of 2,5,6-Trichloro-1-(β-d-ribofuranosyl)benzimidazole

  摘要：

  A series of 5'-modified 2,5,6-trichlorobenzimidazole ribonucleosides has been synthesized and tested for activity against two human herpesviruses and for cytotoxicity. The 5'-methoxy, 5'-ethoxy, and 5'-butoxy analogs of 2,5,6-trichloro-1-(beta-D-ribofuranosyl)benzimidazole (TCRB) were prepared by coupling the appropriate 5-O-alkyl-1,2,3-tri-O-acetyl-beta-D-ribose derivatives with 2,5,6-trichlorobenzimidazole followed by removal of the protecting groups. The 5'-deoxy-5'-fluoro, -5'-chloro, -5'-bromo, -5'-iodo, -5'-azido, and -5'-thiomethyl derivatives were synthesized in a similar fashion. All of these 5'-modified derivatives had significant activity against HCMV in plaque and yield reduction assays (IC50's = 0.5-14.2 mu M) but had little activity (IC50's > 100 mu M) against HSV-1. This pattern is similar to the antiviral activity profile observed for TCRB. The 5'-halogenated derivatives were more active than the other 5'-modified derivatives with antiviral activity well separated from cytotoxicity. In general, cytotoxicity of all the 5'-modified derivatives was greater in human foreskin fibroblasts (HFF cells) than in L1210 or K-B tumor cells. These results indicate that the viral target tolerates significant modifications of TCRB at the 5'-position without adversely affecting activity against HCMV, whereas the 5'-modifications increased cytotoxicity in human diploid cells.

  side effects. Adenosine kinase inhibitors (AKIs) represent an alternative strategy, since AKIs may raise local adenosine levels in a more site- and event-specific manner and thereby elicit the desired pharmacology with a greater therapeutic window. Starting with 5-iodotubercidin (IC50 = 0.026 microM) and 5'-amino-5'-deoxyadenosine (IC50 = 0.17 microM) as lead inhibitors of the isolated human AK, a variety

  腺苷受体激动剂产生多种治疗上有用的药理学。然而，迄今为止，由于剂量限制的副作用，它们未能成功进行临床开发。腺苷激酶抑制剂（AKIs）代表了另一种策略，因为AKIs可以以更多位点和事件特异性的方式提高局部腺苷水平，从而以更大的治疗窗口引发所需的药理作用。从5-碘代小球蛋白（IC50 = 0.026 microM）和5'-氨基-5'-脱氧腺苷（IC50 = 0.17 microM）作为分离的人AK的主要抑制剂开始，各种吡咯并[2,3-d]嘧啶核苷类似物通过使用钠盐介导的糖基化方法将5-取代的4-取代的4-氯吡咯并[2,3-d]嘧啶碱基与核糖类似物偶联来设计和制备。5'-氨基-5' 发现5-溴和5-碘结核菌素的β-脱氧类似物是迄今为止报道的最有效的AKI（IC50S <0.001 microM）。在大鼠最大电击（MES）诱发的癫痫发作试验中，几种有效的AKIs表现出抗惊厥活性。
