title: Epoch-making milestones in antibiotic exploratory researches in Japan.
abstract: Professor Satoshi Ōmura was awarded the 2015 Nobel Prize in Physiology or Medicine. He is the third to win the award for research on antibiotic, following Fleming' (UK, 1945, discovery of penicillin) and Waksman (USA, 1952, discovery of streptomycin), and the second person after Waksman to receive the award for research on actinomycetes. By focusing his research on macrolides stemming from leucomycin research rather than β-lactams like penicillin or aminoglycosides like streptomycin, Prof. Ōmura realized many scientific achievements. These efforts finally led to the discovery of avermectin and its semi-synthetic derivative, ivermectin, considered a monumental contribution to the human race. In this manuscript, I will outline the chronicles of the epoch-making antibiotic exploratory researches preceding Prof. Ōmura.
