Bioinformatics In Pharma Industry

Bioinformatics provides the computational support for functional genomics which will link the behavior of cells, organism amd population to the information encoded in the genomes, as well as structural genomics. The utility of bioinformatics lies in the identification of useful genes leading to the development of new gene products. The subject covers topics such as protein modeling and sequence alignment, expression data analysis, and comparartive genomics. It combines algorithmic, statistical and database methods for studying biological problems also.

The greatest achievement of bioinformatics methods, the Human Genome Project. Because of this the nature and priorities of bioinformatics research and applications are changing. Many experts believe that this will affect bioinformatics in several ways. For instance some scientists also believe what some people refer to as research or medical informatics, the management of all biomedical experimental data associated with particular molecules or patients – from mass spectroscopy, to in vitro assays to clinical side-effects-move from the concern of those working in drug company and hospital IT (information technology) into the mainstream of cell and molecular biology and migrate from the commercial and clinical to academic sectors.

Drug Development

Only 10% of drug molecules identified in research make it through development. This means that many potential drugs do not make it to market, and expensive time and resources are invested m molecules that will generate no revenue. Simulation and informatics can significantly increase these odds by improving the efficiency of drug development, cutting costs, and improving margins.

Formulation Design

Formulation is the process of mixing Ingredients in such a way as to produce a new or improved product. The formulation department must balance the different marketing and deliverability requirements with cost and chemical constraints to come up with the best possible drug delivery method at the best price. With laboratory results stored in legacy systems, it takes expert company knowledge and experience to know which methods and suppliers are available, let alone to locate them quickly. In many cases scientists find that it is easier to repeat an experiment than to find previous results. This situation is compounded in global R&D set-ups, and after mergers and acquisitions.

Crystallisation and Structure Determination

Determining the crystal structure of an active compound is one of the first steps in pharmaceutical development. The crystal structure of a drug affects how easy it is to formulate, its bio-avail- ability, and its shelf life. Knowledge of the different possible polymorphs of a crystal can also give better patent protection for a drug.

Polymer Modeling

Drug delivery is a complex task. The drug must be delivered in a way that transports the active component intact to the appropriate part of the body. The way the cell takes up the drug is also very important: drugs that go to parts of the body other than the intended target are wasted and may lead to unwanted side effects.

Many delivery devices are polymeric with the drug either solubilised or emulsified in the polymer. Drug delivery systems have mesoscale structures; between 10 to 1000 nm. The amount of computing power required to model these systems at an atomistic level is prohibitive, and macroscale techniques such as Finite element analysis or computational fluid dynamics do not give the required level of detail. Mesoscale modeling, focusing on the nanometer length scale, is helping scientists to develop colloidal delivery systems for drugs.

The great advances in human healthcare that are presaged by the Human Genome Project can be realized by the pharmaceutical industry. A prerequisite for this will be the successful integration of bioinformatics into most aspects of drug discovery. Although, from a scientific viewpoint, this is not a difficult problem, there are formidable technological obstacles. Once these are overcome, rapid progress can be expected.

Chemoinformatics is rapidly becoming a core part of drug design informatics, yet the educational opportunities in the field are currently limited.

Like many of today’s emerging life science fields, chemoinformatics has become a ‘hot topic’ while it is still in the process of finding its identity.

Indeed it is not yet clear how to spell the name of the field: some prefer cheminformatics – no ‘o’ – and others, including ourselves, use entirely different terms, such as chemical informatics. What is clear is that the techniques that this field concerns itself with – the processing of chemical and related information on computers – are becoming central to the processes of modern drug discovery.

Interest in chemoinformatics is now becoming widespread, but this greatly increased exposure has highlighted the fact that there are very few people with high-level chemoinformatics skills. The principal source of such individuals in the past has been doctoral students and post-doctoral staff who have spent time in one of the few academic groups world-wide who carry out research in this area, with job opportunities also becoming available to individuals who have worked in areas of chemistry that involve significant computation – such as X-ray crystallography or computational chemistry – or in related areas such as bioinformatics or computational biology. However, there are still too few trained staff available to meet the emerging need, and this has spurred the development of university courses that can provide students with the necessary skills, at both undergraduate and postgraduate levels.

Academic Programs in Chemoinformatics

A small number of universities have established chemoinformatics programs . The most widely recognized and well-established research and teaching base in the field is the Department of Information Studies at the University of Sheffield, which offers Master of science (MSc, or MS) degree and PhD qualifications in chemoinformatics. Subsequent programs have been developed at the University of Manchester Institute of Science and Technology (UMIST), now merged with the University of Manchester, UK, and the School of Informatics at Indiana University (IU), IN, USA.

Careers and Opportunities in Chemoinformatics

After Bioinformatics the next new buzz is Chemoinformatics.. but what is it. Here is an article which I found.


When two scientific disciplines meet, they can be mutually beneficial, fill each other’s voids – and complement each other, giving rise to unprecedented scientific opportunities. One such field of recent interest is chemoinformatics. Chemoinformatics plays a key role in areas as diverse as chemical genomics and drug discovery, the storage of chemical information in databases and the prediction of toxic substances. Today, these techniques are mostly used in pharmaceutical companies in the process of drug discovery, but also for example in “functional foods”, designed by nutritional companies to improve body functions, such as for example digestion or brain function.

While bioinformatics is known since 1976 which is defined as “the study of informatics process in biotic systems”, the emerging terminology in the pharmaceutical sector is commonly referred to as chemoinformatics, which is defined as the “mixing of information resources to transform data into information and information into knowledge, intending for better rapid decisions in the arena of drug lead identification and optimization”.

Chemoinformatics is a generic term that encompasses the design, creation, organization, storage, management, retrieval, analysis, dissemination, visualization and the use of chemical information – so, virtually every area where “chemical data” is accessed or changed by means of computers. Chemoinformatics represents a vital link between experiment and theory in the area of drug design, through the extraction of information from data and conversion into knowledge. With the explosion of publicly available genomic information, such as that resulting from the Human Genome Project, in the middle of the 1990s, bioinformatics has become very popular not only in the scientific community but also among the general audience. This has led to the coining of the counterpart of bioinformatics in chemistry after about two decades as Chemoinformatics. However this field can actually be seen as about two hundred years old – ever since the first account of chemical data has been published in literature.

Today’s technology in chemoinformatics in fact facilitates better organization, storage, retrieval and analysis of these data for further advanced predicting studies – thus, saving time and money, also possibly animal experiments, and advancing humankind by developing novel, and safer, drugs. The last three decades have seen tremendous growth in this field with the advancement in the computer technologies. Today volumes and volumes of books has been written on this subject and even few text books available for teaching in universities at the BSc and MSc level. Though there are full time Masters degree programs available in universities abroad, in India this field has yet to get full recognition.

Currently chemoinformatics is being introduced as part of an ongoing diploma or masters program in bioinformatics in spite of its maturity as a new discipline. Besides the traditional mainstream areas of chemoinformatics such as database systems, computer-assisted structure elucidation systems, computer-assisted synthesis design systems, and quantitative structure-activity relationship (QSAR), several new research areas of chemoinformatics have appeared recently, such as in silico library design, virtual screening, docking, prediction of ADME (Absorption, distribution, metabolism and excretion) and toxicity. It is interesting to notice that at the end of 20th century almost all the major foundations and theories of chemistry had been well understood and established. Chemistry has already evolved from largely a study of the elements to a study of molecules to currently a study of molecular interactions, especially those involving biological macromolecules – the molecules such as proteins and sugars we humans are made of.

This offers a excellent opportunity for chemoinformatics to grow in this new direction. The main focus of recently identified “cyber enabled chemistry” by the US National Science Foundation is on the development of integrated databases, data mining tools, molecular visualization and computational capabilities and the remote and networked use of instrumentation. The scope of this rapidly developing field will certainly continue to expand. It is worth mentioning that there is a new trend of integration of chemoinformatics with bioinformatics. This is because many sectors of the chemical and pharmaceutical industries are interdisciplinary by nature, and major progress and developments in those industries are occurring in both bioinformatics and chemoinformatics side by side. Chemists will become more and more computer dependent, Internet dependent and chemoinformatics dependent. Chemoinformatics through its development in the past half a century, has reached in the present wide acceptance, and will have a bright future!

The purpose of this particular article is to highlight the various research and job opportunities available to a new generation of students in chemistry, computer science and biology at various levels in both academic and pharmaceutical environment.
