The XXI century has disclosed new probabilities in the sphere of drug research and development but it still remains very high-priced procedure. The cost of these researches is often from 897 million of US dollars to 1.9 billion of US dollars. The typical development time is from ten to fifteen years. Research and Development of a new drug needs the finding of a target (e.g. protein) and the disclosure of some proper medication candidates that may block or activate the target. Then come clinical experiments that are the most expensive and significant part of the development because it requires to get a great amount of governmental permissions. Each US drug should have special approval from Food and Drug Administration (FDA). As a result, drug discovery & development procedure is high-priced and difficult process that needs a lot of efforts.

The best method of identification successive drug candidate is examination of the reaction of target protein with various compounds that are selected by scientists from peculiar compound lists where these compounds are situated. Often chemists utilize high-throughput screening (HTS) for this type of testing. Compound lists are commercially accessible in dimensions of up to a few millions of compounds. The most challenging compounds got during the experiment are called hits - these are the compounds that show binding activity towards the target. Later some hits are taken to direct other compounds. In future they will be refined and transformed to have greater outcome from their interaction and less collateral effects.

Nowadays there are several means of drug design. There are shown several methods of discovering medication candidate and you could see their highs and lows:

1. Virtual screening (VS) is the first mode that implies the discovery of virtually made drug and its interaction the same that it is in reality;

This method 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;

- guiding high-throughput screening examinations is expensive and VS may be utilized to reduce the initial number of compounds before using HTS methods;

- a large amount of virtual elements to select from.

There are available a great amount of different elements in virtual screening tests in comparison with the quantity that gives high-throughput screening mode. But we are to claim about the shortage of virtual screening. That is inability to observe real interaction of compounds.

2. High-throughput method (HTS) is a genuine screening and it may research the interaction of thousands of compounds every day. With the help of this method scientists have real results of their researches. It is really high-priced in comparison with preceding 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 drug designing and future characteristics of the medication as a medicine. Nowadays chemists apply 3 basic means for VS in drug discovery process: Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping.
