Cheminformatics Cheminformatics (also known as chemoinformatics, chemioinformatics and chemical informatics) is the use of computer and informational techniques applied to a range of problems in the field of chemistry. Cheminformatics (sometimes referred to as chemical informatics or chemoinformatics) focuses on storing, indexing, searching, retrieving, and applying information about chemical compounds. Through his use of cheminformatics techniques-pattern recognition and data visualization-to create the period table, Dmitri Mendeleev (1834-1907) is often credited as being one of the earliest cheminformatics scientists. In addition to chemical names and formulas, cheminformatics specialists search for and retrieve information about physical properties, three-dimensional molecular and crystal structures, spectroscopic signatures, chemical reaction pathways, molecular functional groups and docking sites, and other parameters, some of which require advanced information technologies. Cheminformatics is the use of computational and informational techniques to understand problems of chemistry, for instance in the in silico mapping of chemical space - the theoretical space occupied by all possible chemicals and molecules. Cheminformatics strategies are useful in drug discovery and other efforts where large numbers of compounds are being evaluated for specific properties. This book focuses on cheminformatics and its applications on drug discovery and modern drug discovery techniques which helps chemist and medical researchers for finding solution to the complex disease.
