The XXI century has disclosed new probabilities in the field of drug discovery and development but it still remains very high-priced procedure. The price of these discoveries is usually from US$ 897 million to US$ 1.9 billion. Scientists need usually fifteen years to discover all the peculiar features of this or that drug. The procedure of a new medication discovery needs finding a target of an experiment (e.g. protein) and after it researchers are to get suitable medications that will interact with a target and give some outcome. Clinical testing is the most comprehensive and high-priced stage in drug research and is done in order to get the necessary government approvals. In the US drugs must be approved by the Food and Drug Administration (FDA). As a result, modern drug discovery procedure is high-priced and arduous process that takes great pains.

One of the most successful methods to identify promising drug candidates is to examine how the target protein interreacts with randomly chosen compounds, which are normally a part of compound list. This testing is often made in so called high-throughput screening (HTS) facilities. Compound libraries are commercially accessible in dimensions of up to a few millions of compounds. The most promising exemplars obtained during the experiment are called hits - these are the compounds that present binding activity towards the target. After that some hits are taken to lead other compounds. Further they will be improved and modified to have greater outcome from their interaction and less collateral effects.

You may find a few various means of drug design nowadays. There are shown several modes of finding medication candidate and you can find their highs and lows:

1. Virtual screening (VS) is the first method that means the discovery of virtually made medication and its interaction the same that it is in reality;

This way has such advantages:

- not so costly, scientists won't synthesize any compounds by themselves and so the costs isn't needed for chemical process;

- it is possible to research compounds that haven't been created still;

- conducting high-throughput screening experiments is high priced and VS may be utilized to diminish the primary amount of compounds before using HTS methods;

- it has a large library of elements that scientists can utilize.

The number of possible virtual elements available for virtual screening is exceedingly greater than the quantity of compounds presently available for HTS. But the main shortage is that the process is not genuine and it can't show everything that can be seen during the real screening.

2. The real screening, such as high-throughput screening (HTS), can experimentally test the activity of hundreds of thousands of elements against the target per day. So scientists get real result during this way of drug discovery. It is definitely high-priced in comparison with preceding method.

Computational methods can be used to forecast or simulate how a particular compound interacts with a given protein target. The means help determine everything that chemists want to know about medications and its future features, collateral effects and etc. when it will be a remedy. The next 3 virtual screening or computational means are applied in the nowadays drug discovery process: Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping.
