Paul Ehrlich promoted chemists "to study the relationship between structure and activity".
He himself worked on azo dyes, containing $-N=N-$ linkage similar to $-As=As-$ linkage in Salvarsan.

The first antibacterial discovered by Paul Ehrlich (a german bacteriologist) was Salvarsan (also called arsphenamine).
In 1908, he got Nobel prize for discovering arsphenamine (salvarsan) to kill syphilis bacteria.

In 1932, Paul Ehrlich prepared antibiotic Prontosil.
Prontosil contains $-N=N-$ linkage similar to $-As=As-$ linkage in Salvarsan. In human body, the sulpha drug prontosil gets converted into sulphanilamide.
