HowdidTuwinChinasfirstNobelPrizeinMedicine?

Background

YouyouTusearchedancientliteratureonherbalmedicineinherquesttodevelopnovelmalariatherapies.TheplantArtemisiaannuaturnedouttobeaninterestingcandidate,andTudevelopedapurificationprocedure,whichrenderedtheactiveagent,Artemisinin,adrugthatisremarkablyeffectiveagainstMalaria.

获奖理由:“因为发现Artemisinin(青蒿素)——一种用于治疗malaria(疟疾)的药物,挽救了全球特别是发展中国家的数百万人的生命。”屠呦呦评奖的关键是三个第一:

第一个把青蒿素带入了“”项目(疟疾防治药物研究项目)

第一个提取出了具有%活性的青蒿素(屠呦呦起到的关键作用就是发现青蒿素受热就失去活性,想到了要用乙醚提取;因为中医是把药物煎成汤药来治疟疾的,而一旦加热到60摄氏度,青蒿素的结构就被破坏,失去了活性,杀不死虐原虫了。)

第一个将青蒿素运用到临床并证实它有效。

Vocabulary

Artemisinin青蒿素,一种用于治疗malaria(疟疾)的药物;青蒿素不是中药,而是从植物中提取的成分单一、结构明确的化学药。有很多化学药最初都是以植物为原料提取或合成的,例如阿司匹林、达菲。

青蒿在中国民间又称作臭蒿和苦蒿,属菊科一年生草本植物,在中国南北方都很常见。

malaria(疟疾),疟疾是一种通过蚊子传播的虫媒传染病,WHO将其列为世界三大死亡疾病之一(另外二大是艾滋病和癌症)。
