Remedy Discovery Methods

Medication discovery and research nowadays has a lot of outlooks but in the same time it is really high-priced procedure. The average total cost per medication research varies from US$ 897 million to US$ 1.9 billion. Often the whole process lasts from 10 to 15 years. At first in the research procedure chemists should identify a target (e.g. protein) and than take various medications that may interact with this target. Medical experiments are the most comprehensive and high-priced phase in drug research and is done in order to get the needed government approbation. In the United States medications must be approved by the Food and Drug Administration (FDA). As you may find drug discovery is an expensive and prolongs procedure today.

One of the best ways to find challenging drug candidates is to examine how the target protein interacts with randomly chosen compounds, which are normally an element of compound libraries. To provide this testing chemists use high-throughput screening (HTS) technology. Compound libraries contain a huge number of compounds that can achieve several thousands. Exemplars that become the most active ones are called hits. Such compounds greatly interreact with the target. Some of these hits are then encouraged to lead compounds - candidate elements which are refined after that and modified in order to achieve more favourable interactions and less collateral effects.

Today there are a few methods of drug design. There are given several modes of finding medication candidate and you could see their highs and lows:

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

This way has such advantages:

- not so costly, scientists won’t synthesize any compounds by themselves and so the expenses is not required for chemical procedure;

- scientists may investigate different compounds that are still in perspective;

- High-throughput screening is really costly and VS presents an opportunity to select a number of useful compounds for further HTS tests;

- huge amount of chemicals to look from.

The number of probable virtual elements accessible for virtual screening is exceedingly greater than the number of compounds presently accessible for HTS. But we must say about the disadvantage of virtual screening. That is impossibility to observe real interaction of compounds.

2. High-throughput method (HTS) is a real screening and it may investigate the reaction of thousands of compounds each day. So researchers get real result during this way of medication discovery. It is definitely high-priced in comparison with preceding method.

Computing methods may be used to predict or simulate how a specific compound reacts with a given protein target. They may be applied to assist in building hypotheses about required chemical features when designing the drug and, besides, they can be used to improve and transform medication candidates. Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping are the methods that are used nowadays in today medication discovery procedures.
