Satoshi Ōmura

Satoshi Ōmura is a Japanese biochemist. He is known for the discovery and development of hundreds of pharmaceuticals originally occurring in microorganisms. In 2015 he shared the Nobel Prize in Physiology or Medicine with Tu Youyou and with William C. Campbell for their role in the discovery of the world's first endectocide, ivermectin, a safe and highly effective microfilaricide. It is believed that the large molecular size of ivermectin prevents it from crossing the blood/aqueous humour barrier, and renders the drug an important treatment of helminthically-derived blindness.
