Combinatorial Chemistry

Introduction Combinatorial Chemistry is a new method developed by

academics and researchers to reduce the time and cost of producing effective, marketable and competetive new drugs.

Scientists use Combinatorial Chemistry to create large numbers of molecules that can be detected efficiently.

This technique has captured the attention of many areas such as Pharmaceutics, Biotechnology and Agrochemistry.

Definition:

Combinatorial chemistry is a technique by which large numbers of different but structurally similar molecules are produced rapidly and submitted for pharmacological assay.

This technique uses the same reaction conditions with the same reaction vessels to produce a large range of analogues.

Application:

Applications of combinatorial chemistry are very wide. Scientists use combinatorial chemistry to create large populations of molecules that can be screened efficiently en masse. By producing larger, more diverse compound libraries, companies increase the probability that they will find novel compounds of significant therapeutic and commercial value.

Tools:

Solid-phase synthesis Resins Reagents(Monomers) Linkers Screening

Advantages:

Saves time Rapid process Produces unexpected new compounds Biological and Chemical applications Saves money

Disadvantages:

Efficiency is highly affected by compound's size, solubility and function group.

Compounds produced tend to be Achiral of Racemic

Future aspect:

20 years ago the market for pharmaceuticals was growing at around 10% per annum but recently it has declined. At the same time, costly pharmaceutical researches have limited the methods to discover new molecules.

It is speculated that Combinatorial Chemistry will allow the productive and cost-efficient generation of compounds and drug molecules, therefore

Combinatorial chemistry will continue to make a major impact on drug manufacture.
