Description NVR 3-778 is a first-in-Class and oral bioavailable HBV CAM belonging to the SBA class It has anti-HBV activity.
In vitro NVR 3-778通过抑制前基因组RNA封装、病毒复制和HBV DNA及HBV RNA含量颗粒的产生,有效抑制具有感染性的HBV DNA含量病毒颗粒的生成,其在HepG2.2.15细胞中的平均抗病毒(EC50:0.40μM)。此外,NVR 3-778还能够抑制初级人肝细胞中的去新生感染和病毒复制,对HBV DNA的EC50值为0.81μM,对HBV抗原生产和细胞内HBV RNA的EC50值在3.7μM和4.8μM之间。NVR 3-778针对HBV核心蛋白,抑制病毒复制,具有广谱的抗病毒活性,并且与HBV复制的核苷(酸)类抑制剂没有交叉耐药性。在含有10%、20%和40%人血清的情况下,NVR 3-778的EC50值分别增加了4.5倍、9.3倍和15.8倍。
In vivo 在犬类通过口服给药后,NVR 3-778 (1.5mg/kg; i.g.) 的平均Cmax和AUC0–inf值分别为0.56μg/ml和3.50μg·h/ml。同时,平均口服生物利用度确定为84.6%。
