- How does Ehrlich's side-chain theory describe the way antibodies recognize invading molecules?
Antibiotics
The discovery, action, and resistance of antimicrobial drugs.
- What did Paul Ehrlich mean by a 'magic bullet' and where did the concept come from?
- Why was compound 606 set aside and forgotten before Sahachiro Hata retested it?
- How did Salvarsan change the prognosis for someone with syphilis?
- In what sense did Salvarsan establish the principle behind modern pharmacology?
- How did confirming the bacterial cause of syphilis connect to the use of salvarsan as a treatment?
- What did Paul Ehrlich mean by a 'magic bullet' (Zauberkugel) and how did Salvarsan fulfill that idea?
- How did Compound 606 target Treponema pallidum, the bacterium behind syphilis, without simply attacking the whole body?
- What made neoarsphenamine an improvement over the original Salvarsan compound?
- How did Ehrlich's targeted-molecule approach shape the drug development that followed, from sulphonamides to penicillin?
- Why was Gerhard Domagk testing coal-tar dyes for antibacterial activity in the first place?
- What happened when Domagk's own daughter Hildegard developed a streptococcal infection?
- How did the discovery of prontosil lead to an entire new class of antibacterial drugs?
- What forced Domagk to delay accepting his Nobel Prize until after the war?

- What did Fleming actually observe on the contaminated Petri dish in 1928?
- How did Waksman and Dubos come to look for antibiotics in ordinary soil?
- How was streptomycin isolated, and why was its effectiveness against tuberculosis so significant?
