Proteomics is the large-scale study of proteins, which are vital parts of living organisms and the main components of cellular metabolic pathways. Chemoinformatics uses computer techniques to study problems in chemistry, especially in pharmaceutical drug discovery where in silico methods are used to aid in the drug design process. Pharmacodynamics and pharmacokinetics are important areas of pharmainformatics that study the effects and mechanisms of drug action on the body as well as the fate of substances administered externally.

1. Proteomics
• Proteomics is the large-scale study of
proteins, particularly their structures and
functions. Proteins are vital parts of living
organisms, as they are the main components
of the physiological metabolic pathways of
cells.

2. Introduction
• Chemo informatics (also known as chemo
informatics and chemical informatics) is the use
of computer and informational techniques,
applied to a range of problems in the field of
chemistry.
• These in silico techniques are used in
pharmaceutical companies in the process of drug
discovery. These methods can also be used in
chemical and allied(group of closely related plant
association) industries in various other forms.

3. • Pharmainformatics plays an important role in
Drug design. It includes various areas like
Pharmacodynamics, pharmacokinetics,
Computational Chemistry, Combinatorial
Chemistry, Chemoinformatics, Toxicology,
Metabolic Modeling etc.

4. Pharmacodynamics
• Pharmacodynamics is the study of the
biochemical and physiological effects of drugs
on the body or on microorganisms or parasites
within or on the body and the mechanisms of
drug action and the relationship between drug
concentration and effect.

5. Pharmacokinetics
• Pharmacokinetics is a branch of pharmacology
dedicated to the determination of the fate of
substances administered (dispensed)
(distributed to num of people) externally to a
living organism.

6. The principles
• The principles of Pharmacokinetics and
Pharmacodynamics are useful to decide the
dosage regimen(therapy course of medical
treatment) which have desired therapeutic
response with minimum toxic effects.
