Ehrlich’s greatest triumph, however, was the discovery (1910) of the organic arsenical drug Salvarsan, which proved to be effective in the treatment of syphilis. In 1903 Ehrlich invented a dye, trypan red, which was the first drug to show activity against trypanosomal infections in mice.

From these studies there emerged (1901–04) Ehrlich’s well-known “side-chain” theory, in which he sought for the first time to correlate the chemical structure of a synthetic drug with its biological effects. He had been led to this by a study of the specific staining of organs of an animal or of a parasite following the injection of a synthetic dye. About 30 years later, Ehrlich found that a synthetic dye, methylene blue, has antimalarial properties. Perkin, in England, made the first aniline dye (1856) as a result of abortive attempts to synthesize quinine, the sole antimalarial drug available at that time.
