Chinese pharmacologist Youyou Tu developed key antimalarial drug artemisinin.
Tu, who won a Lasker prize in 2011, developed the antimalarial drug artemisinin in the late 1960s and 1970s. She is the first China-based scientist to win a science Nobel. “This certainly is fantastic news for China. We expect more to come in the future,” says Wei Yang, president of the nation’s main research-funding agency, the National Natural Science Foundation of China.
Malaria breakthrough
In the 1960s, the main treatments for malaria were chloroquine and quinine, but they were proving increasingly ineffective. So in 1967, China established a national project against malaria to discover new therapies. Tu and her team screened more than 2,000 Chinese herbal remedies to search for drugs with antimalarial activity. An extract from the wormwood plant Artemisia annua proved especially effective and by 1972, the researchers had isolated chemically pure artemisinin.
That Tu won the Nobel prize is “great news”, says Yi Rao, a neuroscientist at Peking University in Beijing who has researched the discovery of artemisinin. “I’m very happy about this. She totally deserves it.”
But there has been some controversy over credit for the discovery, Rao points out, so Tu has never won a major award in China. She has not been elected to either of China’s major academies — neither the Chinese Academy of Sciences nor the Chinese Academy of Engineering.
“Though other people were involved, Tu was clearly the undisputed leader,” says Rao. “But she’s never been given fair recognition within China.”
Lan Xue, an innovation-studies specialist at Tsinghua University in Beijing, says that he has been inundated with messages about the prize. “People will be celebrating, but I hope they also take a sober look, because there are lots of things to learn from this award,” he says.
