Cheminformatics
From Biocrawler, the free encyclopedia.
Cheminformatics is the use of computer and informational techniques, applied to a range of problems in the field of chemistry. Also known as chemoinformatics and chemical informatics, these techniques are used in pharmaceutical companies in the process of Drug Discovery.

Basics
The Cheminformatics combines the scientific working fields of Chemistry and Computer science especially in the area of chemical Graph theory (Bonchev/Rouvray, 1990) and mining the chemical space. It is to be expected that the chemical space contains at least 1062 molecules (Lahana, 1999).
Applications
Screening
Creation of large in silico virtual libraries of compounds using Combinatorial chemistry techniques to increase the efficiency in mining the chemical space.
Quantitative Structure Activity Relationship (QSAR)
Calculation of Quantitative Structure Activity Relationship and Quantitative Structure Property Relationship values, used to predict the activity of compounds from their structures.
File formats
In silico representation of chemical structures, using formats such as the XML based Chemical Markup Language, or SMILES. These representations are often used for storage in large chemical databases. See also Chemical file formats
