Drug discovery and research is an expensive procedure owing to the high costs of Research and Development and human clinical experiments. The usual entire value per medication development differs from US$ 897 million to US$ 1.9 billion. Scientists want approximately fifteen years to discover all the peculiar features of this or that drug. First of all in the research procedure chemists should find a target (e.g. protein) and than take various drugs that may interact with the target. Then come clinical tests that are the most expensive and important phase of the development because it needs to get a great amount of governmental permissions. In the United States medications should be approved by the Food and Drug Administration (FDA). As a result, modern drug discovery procedure is costly and difficult process that needs a lot of efforts.

One of the best ways to identify challenging drug candidates is to investigate how the target protein interreacts with randomly chosen compounds, which are normally a part of compound list. To provide this testing researchers utilize high-throughput screening (HTS) technology. Compound lists are commercially available in sizes of up to several thousands of compounds. Exemplars that become the most successful ones are called hits. Such compounds wonderfully interact with the target. Some of these hits are then encouraged to lead compounds - candidate elements which are further refined and changed in order to get better results and less side-effects.

These days there are several ways of drug design & discovery. There are given several modes of discovering drug candidate and you can find their highs and lows:

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

The advantages that were observed during the experiments are:

- not so costly, chemists will not make any compounds by themselves and so the expenses is not needed for chemical procedure;

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

- High-throughput screening is rather expensive and virtual screening presents an opportunity to choose a number of useful compounds for further HTS experiments;

- it has a huge list of elements that chemists may utilize.

Also VS presents really large amount of elements that can be utilized in research than HTS represents to scientists. But we are to claim about the disadvantage of virtual screening. That is impossibility to see real interaction of elements.

2. High-throughput screening is a real screening and it can use a large number of compounds per day. This mode provides genuine results that are used for medication discovery. Usually, it is really high-priced.

Computing methods can be used to forecast or simulate how a particular compound reacts with a given protein target. The means assist to define everything that scientists need to understand about drugs and its future properties, collateral effects and etc. when it will be a medicine. The following 3 virtual screening or computing means are used in the nowadays medication discovery process: Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping.
