ineffective. This work reports the synthesis and preclinical evaluation of 7 novel 9-O/N/S pyrimidine nucleosides, including compound 12, the triphosphate of compound of known compound 7b. The nucleosides are 9-deaza modifications of adenosine and guanosine with β-2′-C-methyl substituent on the ribose. Within this series of compounds, a 9-deaza furopyrimidine analog of adenosine, compound 7b, showed
丙型肝炎感染是由血源性病原体丙型肝炎病毒 (HCV) 引起的,如果治疗无效,可导致严重的肝脏疾病,并最终导致死亡。本工作报道了7种新型9-O/N/S嘧啶核苷的合成和临床前评价,其中包括化合物12 ,即已知化合物7b的三磷酸酯。核苷是腺苷和鸟苷的 9-脱氮修饰,核糖上带有 β-2'-C-甲基取代基。在该系列化合物中,腺苷的9-脱氮呋喃嘧啶类似物化合物7b在体外表现出高抗HCV活性,在低剂量给药时表现出良好的稳定性、低毒性和低遗传毒性,以及足够的药代动力学特征。与之前的研究相比,还报道了化合物7b的合成改进。合成化合物12作为对照以验证7b在体内发生的磷酸化。
