The years show when a given drug was released onto the pharmaceutical market. This is not a timeline of the development of the antibiotics themselves. 1911 – Arsphenamine , also Salvarsan [ 1 ]
In 1907 Alfred Bertheim synthesized Arsphenamine, the first man-made antibiotic. In 1927 Erik Rotheim patented the first aerosol spray can. In 1933 Robert Pauli Scherer created a method to develop softgels. William Roberts studies about penicillin were continued by Alexander Fleming, who in 1928 concluded that penicillin had an antibiotic ...
Sir Alexander Fleming FRS FRSE FRCS [2] (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin.
The article was translated into Japanese, and production of penicillin was underway by 1 February 1944. By mid-May, a research team under Hamao Umezawa had tested 750 different strains of mould and found that 75 exhibited antibiotic activity. Experiments were conducted on mice to determine efficacy and toxicity.
In addition to P. notatum, newly discovered species such as P. meleagrinum and P. cyaneofulvum were recognised as members of P. chrysogenum in 1977. [19] To resolve the confusion, the Seventeenth International Botanical Congress held in Vienna, Austria, in 2005 formally adopted the name P. chrysogenum as the conserved name ( nomen conservandum ...

Following a 40-year break in discovering classes of antibacterial compounds, four new classes of antibiotics were introduced to clinical use in the late 2000s and early 2010s: cyclic lipopeptides (such as daptomycin), glycylcyclines (such as tigecycline), oxazolidinones (such as linezolid), and lipiarmycins (such as fidaxomicin).
