"Phenethylamine - From Structure to Function" offers a detailed discussion of the pharmacological profiles of representative classes and a comprehensive presentation of structure-activity relationships among various substance classes, incorporating new comparisons of scientific data. The work provides clarity, elucidates chemical relationships, highlights the pharmacological connections of over 2000 compounds, and discusses medicinal chemistry concepts as well as pharmacological methods. Numerous illustrations of old pharmaceutical advertisements underscore the societal relevance of phenethylamines, and a total of nine excursions on topics such as natural products, monoamine transporters, or antidepressants explain historical aspects. The book contains not only well-founded knowledge about well-known substances like Ritalin, MDMA (Ecstasy), or amphetamine but also detailed information about lesser-known compounds and plenty of inspiration for medicinal chemists.
