ABSTRACT
Suresh Rewar* Department of Pharmaceutics, Rajasthan University of Health Sciences, Jaipur, Rajasthan,
The rapid growth of the internet and the World Wide Web has led to the development of pharmacoinformatics technologies to assist oncology healthcare professionals in delivering optimum pharmaceutical care and health related outcomes. There is an increasing recognition that Information Technology can be effectively used for drug discovery. The work in pharmacoinformatics can be broadly divided into two categories - scientific aspects and service aspects. The scientific component deals with the drug discovery and development activities, whereas the service oriented aspects are more patient centric. Pharmacoinformatics subject feeds on many emerging information technologies like neuroinformatics, immunoinformatics, biosystem informatics, metabolomics, chemical reaction informatics, toxicoinformatics, cancer informatics, genome informatics, proteome informatics, biomedical informatics, The minimizing the time between a drug`s discovery and its delivery to the marketplace and maintaining high productivity in the manufacturing processes. During a product`s lifecycle many complex decisions must be made to achieve these goals. To better support the development and manufacturing processes at each stage, we have proposed a new epitome to facilitate the management and transfer of data information and knowledge. In future these information technology efforts are expected to grow both in terms of their reliability and scope. Thus, this emerging technology (pharmacoinformatics) is becoming an essential component of pharmaceutical sciences. Key words: Pharmacoinformatics, Immunoinformatics, Chemoinformatics, Bioinformatics
INTRODUCTION Informatics and internet technologies are becoming extremely popular in today's health-care system. The emergence of the worldwide web has affected the way in which health-related information is distributed and accessed over cyberspace. The internet is rapidly gaining importance, not just for health-care professionals, but also for patients, by enabling them to search for drug-related and other health-related information [1].

Pharmacoinformatics is the study, invention and effectuation of discipline where technology with any aspect of drug delivery, from the basic sciences to the clinical use of medications in individuals and populations. Informatics is commonly defined as the "use of computers to manage data and information" and represents the nexus of people, information, and technology. Includes pharmacy technologies involved in the preparation, delivery, and management of medication use within health care delivery systems [2, 3]. Many applications of pharmacoinformatics currently exist within the health-care sector. These applications have important roles in helping to reduce DRPs in the oncology setting. Studies on the effectiveness of support systems for clinical decisions, e-prescribing, and drug-order entry have shown benefits in reducing medication errors [4-5], and in the prevention and management of chronic diseases [6].

The National Center for Biotechnology Information (NCBI 2001) defines Bioinformatics as "Bioinformatics is the field of
The term bioinformatics first came into use in the 1990s and was originally synonymous with the management and analysis of DNA, RNA and protein sequence data. Computational tools for sequence analysis had been available since the 1960s, but this was a minority interest until advances in sequencing technology led to a rapid expansion in the number of stored sequences in databases such as GenBank. Now, the term has expanded to incorporate many other types of biological data, for example protein structures, gene expression profiles and protein interactions. Each of these areas requires its own set of databases, algorithms and statistical methods [910].
science in which biology, computer science, and information technologies merge into a single discipline [14-15]. There are three important subdisciplines within Bioinformatics: the development of new algorithms and statistics with which to assess relationships among members of large data sets; the analysis and interpretation of various types of data including nucleotide and amino acid sequences, protein domains, and protein structures; and the development and implementation of tools that enable efficient access and management of different types of information [16]." Basically, bioinformatics has three components: The creation of databases, allowing the storage and

5. TOXIC INFORMATICS: Toxicoinformatics involves the use of information technology and computational science for the prediction of toxicity of chemical molecules in the living systems. Early prediction of toxicological parameters of new chemical entities (NCEs) is an important requirement in the drug discovery strategy today. This is being emphasized in the wake of many drug withdrawals in the recent past. Computational methods for predicting toxicophoric features is a cost effective approach toward saving experimental efforts and saving animal life. Current efforts in Toxicoinformatics are mainly based on QSTR (quantitative structure ­ toxicity relationships) and rule - based mechanistic methods. QSTR is a statistical approach, in which a correlation is developed between structural descriptors of a series of compounds and their toxicological data. In this approach, a model can be trained with the help of a set of known data, validated using many approaches, and then used for the prediction of toxicological parameters.
The only limitation of this approach is that the predictive power of these models gets reduced when chemicals' belonging to a class outside the series of molecules is used for the construction of the model. Toxicity prediction tools using this approach include TOPKAT and CASE/M-CASE. TOPKAT mainly employs electrotopological descriptors based on graph theory for the development of QSTR models. TOPKAT uses linear free - energy relationships in statistical regression analysis of a series of compounds. In this software, the continuous/dichotomous toxicity end points are correlated to the structural features like electronic topological descriptors, shape descriptors, and substructure descriptors. CASE (Computer Automated Structure Evaluation) and M - CASE are Toxicoinformatics software packages that have the capability to automatically generate predictive models. A hybrid QSTR artificial expert system - based methodology is adopted in CASE - based systems [35-38].

7. HEALTHCARE INFORMATICS: Biomedical Informatics is an emerging discipline that has been defined as the study, invention, and implementation of structures and algorithms to improve communication, understanding and management of medical information." Medical informatics is more concerned with structures and algorithms for the manipulation of medical data, rather than with the data itself. This suggests that one difference between bioinformatics and medical informatics as disciplines lies with their approaches to the data there are bioinformatics interested in the theory behind the manipulation of that data and there are bioinformatics scientists concerned with the
data itself and its biological implications. Medical informatics, biomedical informatics, clinical informatics, nursing informatics, etc. come under the service-oriented sectors. Other topics like cancer informatics, diabetes informatics are specific therapeutic area based information technology topics. These topics are also related to pharmacoinformatics as a whole because the information obtained from these subjects leads to decision making in pharmaceutical industry. For example, medical informatics deals with medicines and health care. The databases associated with this filed include the feedback received response to a drug. Thus, future designing of the drugs can be made to suit
2567 Suresh Rewar et al, JGTPS, 2015, Vol. 6(2): 2562 - 2571
the needs of the patients. Electronic health record (EHR) systems, Hospital Information Systems (HIS), Decision Support Systems (DSS), etc. are the major components of healthcare informatics [43]. Medical Information Science is the science of using system-analytic tools to develop procedures (algorithms) for management, Process control, decision making and scientific analysis of medical knowledge - Ted Short life. Medical Informatics comprises the theoretical and practical aspects of information processing and communication, based on knowledge and experience derived from processes in medicine and health care - Jan van Bemm. Medical Informatics (MI) is the study of information processing as it is used in healthcare. It might have been called medical computing, but the French-derived term informatics is more commonly used internationally and probably conveys a broader set of concerns, including the uses and flows of information that may have little to do with computers. Like many engineering fields, MI has scientific aspects that focus on the description, modeling and interpretation of how information is actually generated, disseminated and used, and underlying constraints or natural laws that govern these activities. MI is also deeply concerned with the design of appropriate medical information processing systems, with tradeoffs in their implementation, and with ways to evaluate their effectiveness [44]. Some have suggested health informatics as a better, broader term, meant to encompass aspects of health care that are not traditionally the focus of medicine, such as preventive care, nutrition, patient education, epidemiology, etc. Related terms include bioinformatics, which is the study of information processing in biological sciences. Opinion currently varies on whether bioinformatics is part of medical informatics, or-if it forms a distinct discipline-how it relates. Most expect that progress in understanding the molecular basis of disease will bring these fields closer together, if not to merger. Telemedicine (or the recent European coinage telematique) focuses on one aspect of MI, access to and use of medical information at a distance. At MIT, in line with our traditions of institutional flexibility, we have no official organization that does medical informatics, but a number of small foci around the research and teaching interests of faculty in different Departments and Laboratories [42-45]. Pharmacoinformatics preventing adverse drug reactions in hospital patients. Health informatics is concerned with the systematic processing of data, information and knowledge in medicine and healthcare, increasingly delivered by a mix of public and private organisations. Health informatics is delivered by operational health
practitioners, academic researchers and educators, scientists and technologists in operational, commercial and academic domains. The ultimately focus is to improve patient safety and organisational effectiveness to achieve better outcomes [45]. Nursing informatics (NI) is a specialty that integrates nursing science, computer science, and information science to manage and communicate data, information, knowledge, and wisdom in nursing practice. NI supports consumers, patients, nurses, and other providers in their decision making in all roles and settings. This support is accomplished through the use of information structures, information processes, and information technology opportunities in Health broadly cover the following facets, sometimes in combination and with grey boundaries between them [46]. 8. CHEMO INFORMATICS: Chemo informatics is the application of informatics methods to solve chemical problems. All areas of chemistry from analytical chemistry to drug design can benefit from chemo informatics methods. And there are still many challenging chemical problems waiting for solutions through the further development of chemo informatics [46]. The term "Chemoinformatics" appeared a few years ago and rapidly gained widespread use. Workshops and symposia are organized that are exclusively devoted to Chemoinformatics, and many job advertisements can be found in journals. The first mention of Chemoinformatics may be attributed to Frank Brown [47]. Chemo informatics is the arrangement of information resources 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 organization. So chemo informatics is helpful in drug design, Greg Paris came up with a much broader definition. Chemical Data Storage in Databases Data Information Data Retrieval Analysis The current schema of chemoinformatics in drug designing is given below: Analysis of predesigned drug structure structural property prediction (QSAR) property prediction by smiles format perform some modification in prior drug again predict the drug property if variation occurs in novel structure save that structure and design a fragment library [48].Chemoinformatics is a generic term that encompasses the design, creation, organization, management, retrieval, analysis, dissemination, visualization, and use of chemical information. The needs for chemoinformatics recent chemical developments for drug discovery are generating a lot of chemical data. These developments are combinatorial chemistry and high-throughput
2568 Suresh Rewar et al, JGTPS, 2015, Vol. 6(2): 2562 - 2571
screening. Some scientists have described this situation as a chemical information explosion. This has created a demand to effectively collect, organize, and apply the chemical information [4950]. Chemo informatics which deals with the information of the molecules, chemical reaction informatics also plays an important role in the field of pharmacoinformatics. Chemical reaction informatics enable a chemist to explore synthetic pathways, quickly design and record completely new experiments from scratch or by beginning with reactions found in the reaction databases. Chemical reaction informatics a database consists of the following information -Reactants and products, Atom mapping, which allows you to tell which atom, becomes which product atom through the reaction, Information regarding reacting center(s), The catalyst used, The atmosphere, including pressure and composition, The solvent used, Product yield, Optical purity, References to literature. The chemical reaction informatics would essentially assist the chemist in giving access to reaction information, in deriving knowledge on chemical reactions, in predicting the course and outcome of chemical reactions, and in designing syntheses. Specifically, the following tasks can be accomplished by analysis tools in chemical reaction informatics- Storing information on chemical reactions, Retrieving information on chemical reactions, Comparing and analyzing sets of reactions, Defining the scope and limitations of a reaction type, Developing models of chemical reactivity, Predicting the course of chemical reactions, Analyzing reaction networks, Developing methods for the design of syntheses, etc. Applications of Chemo informatics: Chemical Information, All fields of chemistry, Analytical Chemistry, Organic Chemistry, Drug Design and Textile Industry [51].
9. CONCLUSION
Drug discovery and development requires
the integration of multiple scientific and
technological disciplines. These include
chemistry,
biology,
pharmacology,
pharmaceutical technology and extensive use of
information technology. The latter is increasingly
recognised as Pharmacoinformatics. As
discussed above, there is several information
technology efforts related to the pharmaceutical
sciences which are useful for drug discovery. In
future, these efforts are expected to grow both in
terms of their reliability and scope. Thus, this
emerging technology (pharmacoinformatics) is
becoming an essential component of
pharmaceutical sciences.
