莫那匹韦对寨卡病毒感染的体内外疗效

  • 寨卡病毒是一种被广泛关注的黄病毒,具有全球大流行的潜力,可引起严重的神经系统疾病。莫那匹韦(EIDD-2801)已被证明对多种高致病性RNA病毒具有有效的体内外活性,并在美国、英国和中国等国家批准用于治疗SARS-CoV-2。它有可能在当前和未来流行性病中成为重要的口服抗病毒药物。然而,莫那匹韦对寨卡病毒的疗效尚未得到确认。本研究以EIDD-2801的体内代谢形式EIDD-1931进行细胞水平抗病毒研究,并以EIDD-2801/1931进行体内抗寨卡病毒活性评价。结果表明,EIDD-2801和EIDD-1931具有广谱抗黄病毒作用。此外,EIDD-1931剂量依赖性地抑制子代病毒颗粒、病毒RNA和病毒蛋白的产生。腹腔注射EIDD-2801/1931可保护1日龄ICR小鼠免受ZIKV致死性攻击。通过加药时序实验和ZIKV复制子抑制实验,我们发现EIDD-1931可能通过抑制寨卡病毒的复制阶段从而发挥抗病毒活性。我们的研究结果将黄病毒添加到莫那匹韦的抗病毒谱中,它极有可能成为抗黄病毒感染(包括ZIKV)的有效候选抗病毒药物。
