All the Facts about Today s Drug Research Methods

By Mathew Petrenko

Drug discovery and development today has a great number of outlooks but in the same time it is very high-priced procedure. The average entire cost per drug development differs from US$ 897 million to US$ 1.9 billion. The typical research time is 10-15 years. Research and Development of a new drug needs the identification of a target (e.g. protein) and the discovery of some suitable drug candidates that may block or activate the target. Clinical testing is the most extensive and high-priced stage in medication research and is made in order to obtain the necessary governmental approvals. In the US medications should be endorsed by the Food and Drug Administration (FDA). As a result, drug discovery & development process is high-priced and difficult procedure that needs a lot of efforts.

Scientists utilize the way of interacting the target with different compounds to identify the best drug candidate. They get a target protein and observe the reaction of it with compounds that they have in particular compound library. Often scientists use high-throughput screening (HTS) for this type of testing. Compound libraries are commercially accessible in sizes of up to a few thousands of compounds. Exemplars that become the most active ones are named hits. Such exemplars wonderfully interact with the target. After that some hits are taken to direct compounds. In future they will be refined and transformed to have better results from their interaction and less collateral effects.

Nowadays there are several means of drug design & discovery. The following are methods for finding a medication candidates, along with their advantages and disadvantages:

1. Virtual screening (VS) is a mode that makes researches virtually as if there genuine screening were used;

The advantages that were seen during the experiments are:

- it is inexpensive because it doesn’t require any expenses for scientists who will make compounds;

- it gives a probability to see the reactions that will be given by compounds that are still do not exist;

- the thing that high-throughput screening method is rather high-priced makes chemists utilize virtual screening to choose the best compounds virtually and then use this definite amount of them during HTS tests;

- it has a large library of chemicals that chemists can utilize.

The quantity of possible virtual molecules accessible for VS is exceedingly greater than the number of compounds presently accessible for HTS. But the main shortage is that the procedure is not real and it may not show all that may be seen during the real screening.

2. The real screening, such as high-throughput screening (HTS), may show in practice the interaction of hundreds of thousands of elements against the target per day. This mode provides genuine results that are used for medication discovery. It is really high-priced in comparison with previous method.

The means of research are applied to identify how a given element reacts with a target. It is made for determination the results and chemical properties of medication creating and future features of the drug as a medicine. Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping are the means that are utilized nowadays in nowadays drug discovery procedures.
