What was arsphenamine used for?
History of Microbiology His search for such compounds led to the discovery of several drugs useful in the treatment of protozoal and spirochetal diseases between 1905 and 1915. The arsenical compound, arsphenamine (salvarsan, compound 606), was used to treat syphilis until the advent of penicillin.
Who found arsphenamine?
The use of antibiotics developed in 1943 after the discovery by the American physician John Friend Mahoney… The first of these was arsphenamine, which was developed in 1910 by the German medical scientist Paul Ehrlich for the treatment of syphilis.

Was Salvarsan the first antibiotic?
Arsphenamine, also known as Salvarsan or compound 606, is a drug that was introduced at the beginning of the 1910s as the first effective treatment for syphilis and African trypanosomiasis. This organoarsenic compound was the first modern antimicrobial agent.

How was Arsphenamine discovered?
The antisyphilitic activity of this compound was discovered by Sahachiro Hata in 1909, during a survey of hundreds of newly synthesized organic arsenical compounds. Ehrlich had theorized that by screening many compounds, a drug could be discovered that would have anti-microbial activity but not kill the human patient.
Why are antibiotics called magic bullets?
He named the hypothetical agent as Zauberkugel, the “magic bullet.” He envisioned that just like a bullet fired from a gun to hit a specific target, there could be a way to specifically target invading microbes.
