  5. Bioinformatics Tools • The processes of designing a new drug using bioinformatics tools have open a new area of research. I • In order to design a new drug one need to follow the following path. • Identify target disease • Study Interesting Compounds • Detection the Molecular Bases for Disease • Rational Drug Design Techniques • Refinement of Compounds • Quantitative Structure Activity Relationships (QSAR) • Solubility of Molecule • Drug Testing

  6. Bioinformatics Tools • Identify Target Disease:- 1. One needs to know all about the disease and existing or traditional remedies. It is also important to look at very similar afflictions and their known treatments. 2. Target identification alone is not sufficient in order to achieve a successful treatment of a disease. A real drug needs to be developed.

  7. Bioinformatics Tools • Study Interesting Compounds:- • One needs to identify and study the lead compounds that have some activity against a disease. 2. These may be only marginally useful and may have severe side effects. 3. These compounds provide a starting point for refinement of the chemical structures.

  8. Bioinformatics Tools • Detect the Molecular Bases for Disease:- • If it is known that a drug must bind to a particular spot on a particular protein or nucleotide then a drug can be tailor made to bind at that site. • This is often modeled computationally using any of several different techniques.

  9. Bioinformatics Tools • Detect the Molecular Bases for Disease:- 3. Traditionally, the primary way of determining what compounds would be tested computationally was provided by the researchers' understanding of molecular interactions. 4. A second method is the brute force testing of large numbers of compounds from a database of available structures.

  10. Bioinformatics Tools • Rational drug design techniques:- 1. These techniques attempt to reproduce the researchers' understanding of how to choose likely compounds built into a software package that is capable of modeling a very large number of compounds in an automated way. 2. Many different algorithms have been used for this type of testing, many of which were adapted from artificial intelligence applications.

  11. Bioinformatics Tools • Refinement of compounds:- 1. Once you got a number of lead compounds have been found, computational and laboratory techniques have been very successful in refining the molecular structures to give a greater drug activity and fewer side effects.

  12. Bioinformatics Tools • Quantitative Structure Activity Relationships (QSAR):- 1. Computational technique should be used to detect the functional group in your compound in order to refine your drug. 2. QSAR consists of computing every possible number that can describe a molecule then doing an enormous curve fit to find out which aspects of the molecule correlate well with the drug activity or side effect severity. 3. This information can then be used to suggest new chemical modifications for synthesis and testing.

  13. Bioinformatics Tools • Solubility of Molecule:- 1. One need to check whether the target molecule is water soluble or readily soluble in fatty tissue will affect what part of the body it becomes concentrated in. 2. The ability to get a drug to the correct part of the body is an important factor in its potency.

  14. Bioinformatics Tools • Drug Testing:- 1. Once a drug has been shown to be effective by an initial assay technique, much more testing must be done before it can be given to human patients. 2. Animal testing is the primary type of testing at this stage. Eventually, the compounds, which are deemed suitable at this stage, are sent on to clinical trials. 3. In the clinical trials, additional side effects may be found and human dosages are determined.
