Introduction
The science of chemistry is so broad that it is normally broken into fields or branches of specialization. The manufacture of drugs and dyes is one of the most practical industrial applications of chemistry.

The development of dyes and medicines has always been connected. Scientists working to discover and synthesize both dyes and drugs developed the organic, synthetic chemistry that gave birth to the pharmaceutical industry at the end of the nineteenth century and the beginning of the twentieth. In fact, it was the accidental discovery of the first synthetic dye by Henry Perkin in England in 1856 that ushered in the age of synthetics. Perkin had been trying to synthesize the antimalarial drug quinine when he discovered a mauve dye later popularized by Queen Victoria. On the other side of this intimate connection between drugs and dyes, nineteenth-century chemists noticed the antibacterial properties some dyes exhibited in test tubes and then investigated their uses as therapeutic agents. Many proved to be quite useful. Paul Ehrlich, the German drug developer, systematically studied aniline dyes and modified them for use as drugs Research during the early years of dye synthesis produced compounds such as methylene blue and acriflavine, which were used as biological stains. The selectivity of such compounds for “non-economic” cells such as pathogenic bacteria or tumor cells gave rise both to the principle of selective toxicity and to the development of many modern drugs. The use of dyes in therapy is again gaining credence today, given the efficacy of light-activated drugs based on dye molecules against drug-resistant organisms such as MRSA. In addition, because of the ongoing prevalence of “superbugs”, older drugs developed from dye chromophores may again be of use in medical settings.

It is the intent of this collection to present the reader with a broad spectrum of articles in the particular area of drugs and dyes, thereby demonstrating key developments in this rapidly changing field.
