Novel solid phase synthesis of 2'-o-methylribonucleoside 5'-triphosphates and their α-thio analogues
摘要:
Simple, versatile and convenient syntheses of 2'-0-methyl-ribonucleoside 5'-triphosphates have been accomplished on controlled pore glass (CPG) in good yield (>60%) using 2-chloro-4H-1,3,2-benzodioxaphosphorin-4-one (salicyl phosphorochloridite). Moderate yields were obtained for the corresponding alpha-thiotri-phosphates.

Oligonucleotides bearing 5' triphosphate are recognized by RIG-I, leading to the induction of type I IFN production. Bacterial RNA also induces type I IFN production. 5' triphosphate oligonucleotides and bacterial RNA can be used for inducing an anti-viral response or an anti-bacterial response, in particular, type I IFN production, in vitro and in vivo and for treating various disorders and diseases including viral infections, bacterial infections, and tumors. Furthermore, oligonucleotides bearing 5' triphosphate can induce IL-18 and IL-1β production, and are thus useful in the treatment of various disorders and dieases such as allergies, autoimmune diseases, immunodeficiencies and immunosuppression.
含有 5' 三磷酸的寡核苷酸会被 RIG-I 识别,从而诱导 I 型 IFN 的产生。细菌 RNA 也能诱导 I 型 IFN 的产生。5' 三磷酸寡核苷酸和细菌 RNA 可用于体外和体内诱导抗病毒反应或抗菌反应,特别是 I 型 IFN 的产生,并可用于治疗各种疾病,包括病毒感染、细菌感染和肿瘤。此外,含有 5' 三磷酸的寡核苷酸可诱导 IL-18 和 IL-1β 的产生,因此可用于治疗各种紊乱和疾病,如过敏、自身免疫性疾病、免疫缺陷和免疫抑制。
