Chemical library is a term used in biochemistry to refer to a collection of small molecules used for drug discovery. The spelling of this term is transcribed as /ˈkɛmɪkəl ˈlaɪbrɛri/. The word "chemical" is pronounced with a short "e" sound as in "bet" followed by a strong stress on the first syllable. "Library" is pronounced as "laɪ-bruh-ree" with a long "i" sound in the second syllable and a weak stress on the first syllable. This term is commonly used in drug discovery research and is an essential component of the development of new medicines.
A chemical library refers to a vast collection of small-molecule chemical compounds that are systematically organized and stored for research and drug discovery purposes. It is essentially a repository containing numerous unique and diverse chemical structures that can be screened and utilized by scientists to identify new lead compounds for drug development.
Chemical libraries are constructed by synthesizing or obtaining a wide range of small molecules, often numbering in the thousands or millions, with varying chemical properties and structures. These compounds may be sourced from diverse natural sources such as plants, microorganisms, or marine organisms, or they can be synthesized using combinatorial chemistry techniques.
The chemical library serves as a valuable resource for researchers, enabling them to identify compounds that exhibit desired biological activity, such as inhibiting specific enzymes or interacting with biological targets implicated in diseases. High-throughput screening methods are frequently employed to rapidly test numerous compounds against a specific target or disease model.
Moreover, chemical libraries are important in drug discovery and development as they provide a starting point for medicinal chemists to optimize the identified hits and improve their potency, selectivity, and pharmacokinetic properties, to ultimately produce an effective drug candidate.
Overall, chemical libraries are indispensable tools in the field of pharmaceutical sciences, aiding in the identification and development of new therapeutic agents that can potentially combat human diseases and improve healthcare.
The term "chemical library" is composed of two words: "chemical" and "library".
1. "Chemical": The word "chemical" originates from the Middle English word "chemic" or "chymic", which came from Old French "chimie" or "chymie", and ultimately from the Medieval Latin word "chimia" or "chymia". This Latin term is derived from the Arabic word "al-kīmiyāʼ" (الكيمياء), which refers to the science of alchemy. Alchemy was an ancient practice that involved the transformation of materials and the pursuit of the philosopher's stone, which was believed to grant immortality. Over time, "alchemy" transformed into "chemistry" and the term "chemical" came to refer to substances and processes related to chemistry.
