Arsphenamine, also known as Salvarsan or compound 606, is an antibiotic drug that was introduced at the beginning of the 1910s as the first effective treatment for the deadly infectious diseases syphilis, relapsing fever, and African trypanosomiasis. [2] [3] This organoarsenic compound was the first modern antimicrobial agent. [4]
1911 – Arsphenamine, also Salvarsan [1] 1912 – Neosalvarsan; 1935 – Prontosil (an oral precursor to sulfanilamide), the first sulfonamide; 1936 – Sulfanilamide; 1938 – Sulfapyridine (M&B 693) 1939 – sulfacetamide; 1940 – sulfamethizole; 1942 – benzylpenicillin, the first penicillin; 1942 – gramicidin S, the first peptide ...
Their discoveries were the result of the first organized team effort to optimize the biological activity of a lead compound through systematic chemical modifications. [1] This scheme is the basis for most modern pharmaceutical research. Both Salvarsan and Neosalvarsan are prodrugs – that is, they are metabolised into the active drug in the body.
The drug was marketed under the name Salvarsan and gained international acclaim as the "arsenic that saves" and as the first man-made antibiotic. [7] In the wake of their discovery, some sections of European society condemned Hata's and Ehrlich's 'magic bullet' because they believed that syphilis was a divine punishment for sin and immoral acts ...
Although arsenic and its compounds are toxic for humans, one of the first synthetic antibiotics was Salvarsan, the use of which has long been discontinued. The only polyarsenic compound isolated from a natural source is arsenicin A , found in the New Caledonian marine sponge Echinochalina bargibanti .
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 ...
When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...
Béchamp also synthesized the first organic arsenical drug, arsanilic acid, from which Paul Ehrlich later synthesized salvarsan, the first chemotherapeutic drug. Béchamp's rivalry with Pasteur was initially for priority in attributing fermentation to microorganisms, later for attributing the silkworm disease pebrine to microorganisms, and ...
