TU YOUYOU


Hi again readers!


This time, I am going to speak about a person who is very important for the actual humanity. In ICT classes, we are seeing the different Nobel Prize Winners of different years, and I have chosen one of this year, that is the Nobel Prize in physiology and medicine. The main reason is because I like this two sciences, because the prize is very actual and because her investigation saved millions of lives. The winners name is Tu Youyou, and she won "for her discoveries concerning a novel therapy against Malaria".

Now I am going to explain yo a little bit of her life, and also the investigation of malaria.

She attended Xiaoshi Middle School for junior high school and the first year of high school, before transferring to Ningbo Middle School in 1948. From 1951 to 1955, she attended Peking University Medical School / Beijing Medical College. Tu studied at the Department of Pharmaceutical Sciences, and graduated in 1955. Later, she was trained for two and a half years in traditional Chinese medicine.

After graduation, Tu worked at the Academy of Chinese Medicine in Beijing. She was promoted to a Researcher in 1980 shortly after the Chinese economic reform began in 1978. In 2001 she was promoted to academic advisor for doctoral candidates. Currently she is the Chief Scientist in the Academy.

Tu started her malaria research in China when the Cultural Revolution was in progress. In early 1969, she was appointed head of the project, named Project 523 research group at her institute. She collected 2000 candidate recipes, ancient texts, and folk remedies for possible leads for her research. By 1971, her team had made 380 extracts from 200 herbs, and discovered the extracts from qinghao looked particularly promising in dramatically inhibiting Plasmodium growth in animals. Tu found the way to extract it and her innovations boosted potency and slashed toxicity of this extract. In 1972, she and her colleagues obtained the pure substance and named it qinghaosu , or artemisinin as it is commonly called in the west, which has saved millions of lives, especially in the developing world. She also studied the chemical structure and pharmacology of artemisinin. Tu's group first determined the chemical structure of artemisinin. In 1973, she wanted to confirm the carbonyl group in the artemisinin molecule, therefore she accidentally synthesized dihydroartemisinin. For her work, she was awarded the Nobel Prize in Medicine on 5 October 2015.
