利巴韦林(Ribavirin),俗称病毒唑,一种具广谱抗病毒特性的鸟苷类似物,靶向包括呼吸道合胞病毒(RSV)、丙型肝炎病毒(HCV)和流感病毒在内的DNA和RNA病毒。利巴韦林是一种药物前体,能够被细胞内激酶单磷酸或三磷酸化而激活。这些磷酸化衍生物对细胞和病毒内的酶产生各种效应,引起病毒复制的抑制。利巴韦林结合并重新分布哺乳动物eIF4E从细胞核到细胞质(Ki~ 0.3 μM,利巴韦林三磷酸,活性代谢物)。能够抑制原代AML-M5祖细胞的克隆形成(IC50~1 μM),还能减缓急性髓细胞性白血病(AML)的疾病严重程度。

体内研究: 动物模型(Animal Model):DENV (serotype 2, TSV01 strain) infected mice 给药剂量(Dosages):The mice were challenged with DENV (serotype 2, TSV01 strain), at 5×106pfu/mouse via i.p. injection. Imino sugar (CM-10-18) was given orally at 75mg/kg twice daily at 12 hr intervals, andribavirin was given orally at 40mg/kg once daily, for 3 consecutive days post-infection. PBS was given to control mice.Blood samples were drawn 3 days post-infection for determination of plasma virus titer by plaque assay. 实验结果(Results):While ribavirin at 40mg/kg by itself did not reduce viremia, and 75 mg/kg of CM-10-18 treatment only modestly reduced the viremia by 1.9-fold, combination of the two compounds reduced the viremia by 4.7-fold. |

体内研究: 动物模型(Animal Model):Female 5- to 7-week old athymic NCr-nu/nu mice 药物配制(Preparation):For treatments, drugs were dissolved in PBS (pH 7.4) and filter-sterilized. Untreated cells and animals received filter-sterilized PBS. 给药剂量(Dosages):Nude mice were engrafted by using sub-cutaneous injection of eIF4E-dependent FaDu cells andtreated with 40 μg/kg ribavirin orally each day, yielding a mean body concentration of ≈1 μM.Photograph of tumors resectedafter 20 days of treatment. 实验结果(Results):After 20 days of ribavirin treatment, mean tumor volume of animals in the treatment group was 6-fold less than those in the untreated control group. At this low concentration, ribavirin was apparently well tolerated and minimally toxic as suggested by the absence of treatment-associated mortality and of effect on body weight. |
