Part of speech: noun

Definitions

3. Known for their potential applications in medicinal chemistry, particularly in the development of therapeutic agents

Etymology: Piperazines are a family of chemical compounds, and the name is a coinage built from two older chemical words. The first part, "piper", comes from "piperidine", the name for a compound first obtained from black pepper, whose Latin name is "piper". The second part, "azine", is a chemical suffix denoting a ring structure containing nitrogen atoms. Piperidine and azine were joined to name the piperazine ring, which contains two nitrogen atoms opposite each other, so the name describes a structure rather than a substance found in nature. The term was borrowed into English from German "Piperazin", the form the compound's name took in that language. Chemists working in German-speaking laboratories did much of the early naming of nitrogen-containing ring compounds, and English chemical vocabulary often followed their pattern. The plural simply refers to multiple members of this compound family, and the word is now used mainly in pharmacology, where the piperazine ring appears in many drug molecules.
