从2013年12月的埃博拉疫情爆发以来,这次最严重的爆发在西非三个国家的死亡人数已经达到了9500人以上。埃博拉病毒以其高死亡率而著称,因此,世界卫生组织将其列为对人类危害最严重的病毒之一。科学家们正在努力寻找能够有效治疗和预防埃博拉病毒感染的药物,在抗病毒方面具有优势的中药进入了他们的视野,并在初步实验中得到了肯定。




科学家们在周四说到,一种中草药的提取物抗击埃博拉感染非常有效,这种成分可以将病毒困在细胞内部从而让它不能对机体造成损伤。

研究员们说这种物质叫做粉防己碱,它可以阻断体外培养的人类白细胞中的感染传播,还可以预防实验小鼠感染埃博拉病毒。但是粉防己碱在应用于人类前还需要进一步的研究,包括在猴子身上的实验。

“这项研究让我们看到了埃博拉病毒坚硬的盔甲上的小缺口。”圣安东尼奥德克萨斯生物化学研究所的病毒学家Robert Davey说。他估计这项研究成果很可能会在未来2-5年内用于治疗感染埃博拉病毒的人们。

“我希望用于控制病情发展的剂量是安全的,但结果如何我们仍需要进一步研究。”Davey补充道。

埃博拉病毒可以引起出血热,并且可以通过体液接触传播,然而目前并没有有效的经过证实的有效的药物治疗措施和疫苗来应对埃博拉病毒。

“在我看来,粉防己碱是目前可以抑制埃博拉病毒感染最有效的药物之一。”德国弗莱堡大学的药理学家和微生物学家Norbert Klugbauer说,她同时也参与《Science》上发表的一项研究。

为了成功感染一个细胞,病毒需要被内涵体转运到细胞深部,然后冲破这个像泡泡一样的细胞内运输结构。研究人员们发现了细胞内部控制这种“泡泡”运动的通道,叫做“双孔通道”。研究表明粉防己碱阻断了这些通道,能有效地将病毒封锁在“泡泡”里,使其无法真正感染细胞。

“然后病毒就被困在了泡泡里不能逃离,然后就被间接地消灭了,于是这阻断了感染。” Davey说。

在体外培养的人类细胞中,研究人员们发现粉防己碱抑制感染的机制与巨噬细胞有关。巨噬细胞是人体免疫系统的一个重要角色,它能抵御外来入侵者们比如病毒和细菌,通常来说它会吞噬掉这些外来者。

粉防己碱是从一种药用植物粉防己的根茎中提取的,它还可以用来降血压。

希望相关实验可以尽快完成,给深受埃博拉病毒感染困扰的人们带来福音。
