Kids Encyclopedia Facts

Cheminformatics (also known as chemoinformatics and chemical informatics) is the study of large amounts of chemical information. It is done mostly with the help of computers. These tools are used by pharmaceutical companies to discovery new drugs.

Cheminformatics uses computer science and information technology to help solve chemistry problems. Cheminformatics deals with algorithms, databases and information systems, web technologies, artificial intelligence and soft computing, information and computation theory, software engineering, data mining, image processing, modeling and simulation, signal processing, discrete mathematics, control and system theory, circuit theory, and statistics, for generating new knowledge of chemistry.

History

The term chemoinformatics was defined by F.K. Brown in 1998:

Basics

Cheminformatics combines the scientific working fields of chemistry and computer science. Cheminformatics can also be applied to data analysis for the paper, pulp and dye industries.

Uses

Storage and retrieval

The primary application of cheminformatics is in the storage of information relating to compounds. The efficient search of such stored information includes topics that are dealt with in computer science as data mining and machine learning.

File formats

Computers represent chemical structures in specialized formats such as the XML-based Chemical Markup Language or SMILES. While some formats are suited for visual representations in 2 or 3 dimensions, others are more suited for studying physical interactions, modeling and docking studies.

Virtual libraries

Chemical data can pertain to real or virtual molecules. Virtual compounds may be used to explore chemical space and predict new compounds with desired properties.

Virtual libraries of classes of compounds (drugs, natural products, diversity-oriented synthetic products) were recently generated using the FOG (fragment optimized growth) algorithm.

Virtual screening

Instead og testing the actual chemicals, virtual screening involves screening compounds by computer, to identify members likely to possess desired properties such as biological activity against a given target.
