Rational drug design: a multidisciplinary approach.
The pharmaceutical industry developed spasmodically and, in its early years, was shaped by several notable events and scientists. Paul Ehrlich, whose studies initiated the field of chemotherapy, was one of the major contributors. From early experiments on the efficacy of the biological stain methylene blue as an anti-malarial, Ehrlich realized that small molecules could be used to treat infections. Further studies identified trypan dyes and arsenical compounds as treatments of trypanosomal infection, and the arsenical compounds were found to be effective against syphilis. Ehrlich's experience of the chemical industry, in particular the chemistry of dyes, led to the realization that synthetic molecules could be medically useful and provided a powerful stimulus to pharmaceutical research.
