Yoshimasa Hirata


Yoshimasa Hirata was a Japanese organic chemist.

Biography

Hirata was born in Yamaguchi, Japan in 1915. He received a Bachelor of Science from the Tokyo Imperial University in 1941, and then joined the faculty there as a Lecturer of Chemistry. In 1944, he moved to Nagoya University as an Assistant Professor in the Department of Chemistry. In that same year, he was promoted Associate Professor. He received his Ph.D. from Nagoya University in 1949, and was promoted to Full Professor in 1954.
In 1955, Hirata met a recent graduate from Nagasaki Pharmacy School, a young Osamu Shimomura. He invited Shimomura to work in his lab, which he did, in April 1955. Hirata tasked him with purifying crystallizing Cypridina luciferin for the purpose of determining its structure. He completed the difficult task after three months, and Hirata awarded him with a doctorate, despite him not being a doctoral student.
In 1979, Hirata moved to Meijo University, staying there for ten years before retiring.

Research

Hirata's best known research was that involving toxic compounds, including tetrodotoxinpandalytoxin, his research of the bioluminescent compound Cypridina luciferin from the vargula hilgendorfii, also known as the sea firefly, and his work on bioactive compounds of plant origin, including anisatin, dendrobine, and daphniphylline.
