Chemistry is largely built on experimental observations and data, it deals with compounds, their properties, and their transformations. Compounds and chemical reactions are the static and dynamic aspects of chemistry. The entire living and material world consists of compounds and mixtures of compounds. Compounds are transformed into each other by chemical reactions that can be run under a variety of conditions.
Although the laws of chemistry are too complicated to be solved, chemists still can do their jobs and make compounds with beautiful properties that society needs and chemists still run reactions from small‐scale laboratory experiments to large scale reactors in the chemical industry. The secret to success has been to learn from data and from experiments. The process of learning is called inductive learning as shown in Fig. 1.
The amount of data and information is enormous and increasing rapidly. At present, more than 41 million different compounds are known, all have a series of properties, physical, chemical and biological; all can be made in many different ways, by a wide range of reactions; all can be characterized by a host of spectra. Problem is to extract knowledge from these data and use it to make predictions. Three major tasks of structure‐property / activity relationships, design of reaction/syntheses and structure elucidation are tackled by making use of prior information, and of information that has been condensed into knowledge. The amount of information that has to be processed is often quite large.
This immense amount of information can be processed only by electronic means, by the power of the computer. This is how cheminformatics is useful.
What is Cheninformatics?
Cheminformatics is the study of all aspects of the representation and use of chemical and related biological information on computers. It has applications in drug discovery health, data mining, and many other areas. According to the National Center of Biotechnology Information, cheminformatics is a relatively new field of information technology that focuses on the collection, storage, analysis, and manipulation of chemical data. The chemical data of interest typically include information on properties, spectra, small molecule formulas, structures, and activity (biological or industrial).
Cheminformatics originally emerged as a channel to assist the discovery and development process of drugs. However, cheminformatics now plays a crucial role in many areas of chemistry, biochemistry, biology. Since the 1950s, several foundational algorithms of cheminformatics have been described. But open-source software, implementing the algorithms, became accessible only since the mid-1990s, which is around 40 years later. But in 2004, a large public small molecule structure repository was made freely available by the National Library of Medicine.
History
There is no particular point in time that determines when chemoinformatics was founded or established. It slowly evolved from several, often quite humble beginnings. Scientists in various fields of chemistry struggled with the development of computational methods, which allowed them to manage the enormous amount of chemical information and to find relationships between the structure and properties of a compound. During the 1960s some early developments appeared that led to a flurry of activities in the 1970s.
Importance & Scope of Cheminformatics:
- Cheminformatics is the use of computer and informational techniques applied to a range of problems in the field of chemistry. These information techniques to transform data into information and information into knowledge for the intended purpose of making better decisions faster in the area of drug lead identification and optimization.
- Cheminformatics combines the scientific working fields of chemistry, computer science, and information science in the areas of topology, chemical graph theory, information retrieval and data mining in the chemical space.
- The primary application of cheminformatics is in the storage, indexing, and search of information relating to compounds.
- Cheminformatics is a discipline organizing and coordinating the application of computers in chemistry.
- Cheminformatics covers complementary disciplines that hold great promise for the advancement of research and development in biological systems, software development, techniques, drug design, and so on.
NEED OF CHEMINFORMATICS
The primary application of chemoinformatics includes storage, indexing, searching for information about the appropriate compounds. It maintains an access amount of chemical data and also accesses it by using a proper database. It is a significant application of information used to organize, analyze, to solve other new problems and to understand scientific data in the development of novel compounds.
