Study Notes
20th Century Medical Advances
- Significant advancements in medicine built upon 19th-century discoveries, leading to increased life expectancy.
- Researchers sought "magic bullets" – chemicals to kill germs without harming human tissue, following Pasteur's germ theory and Koch's bacterial identification methods.
- Paul Ehrlich, working with Koch, explored using industrial dyes to target bacteria. Ehrlich theorized specific chemicals could kill germs selectively.
- Ehrlich and Hata tested hundreds of chemical compounds on syphilis-infected rabbits, seeking a compound that cured without harming the rabbits.
- Salvarsan 606, the 606th compound tested, proved effective in treating syphilis.
- Salvarsan 606 was the first "magic bullet," a chemical cure for syphilis.
- Salvarsan 606 spurred research for other "magic bullets."
- In 1935, Gerhard Domagk discovered Prontosil, the second magic bullet, an antibacterial drug effective against streptococcal bacteria.
- This led to further exploration of natural substances for targeting infections and the eventual discovery of penicillin.
