Drug discovery and development today has a great number of perspectives but in the same moment it is very expensive process. You can see that a cost of medical discoveries and development needs form US$ 897 million to US$ 1.9 billion. Often the whole procedure lasts from 10 to 15 years. First of all in the research procedure scientists are to find a target (e.g. protein) and than get various drugs that may interact with the target. Then come medical experiments that are the costliest and important part of the development because it requires to get a great amount of governmental approvals. In the United States medications should be approved by the Food and Drug Administration (FDA). As one can find drug discovery & development is a costly and prolongs process today.

One of the most successful ways to find challenging drug candidates is to investigate how the target protein interreacts with randomly selected compounds, which are normally a part of compound libraries. This examination is often done in so called high-throughput screening (HTS) technologies. Compound lists combine a large amount of samples that may achieve a few millions. The most challenging compounds obtained during the experiment are called hits - these are the compounds that show combining activity towards the target. Some of these hits are then promoted to direct compounds - candidate structures which are further refined and changed in order to get more favourable results and less side-effects.

You may find a few diverse methods of drug design & discovery nowadays. Further you can find different means for finding drug candidate where you will also find their advantages and disadvantages:

1. Virtual screening (VS) based on the computing deduced or simulated real screening;

The main benefits of this method in comparison with laboratory experiments are:

- low costs, no elements have to be bought externally or synthesized by a chemist;

- chemists may research different compounds that are yet in perspective;

- guiding HTS experiments is high priced and virtual screening may be utilized to diminish the primary number of compounds before using HTS methods;

- great amount of elements to look from.

The quantity of probable virtual elements available for virtual screening is exceedingly greater than the number of compounds presently accessible for HTS. But the basic disadvantage is that the procedure is not genuine and it can’t show everything that may be observed during the real screening.

2. High-throughput screening is a real screening and it may use a large number of elements per day. So scientists get genuine outcome during this way of drug discovery. Usually, it is highly high-priced.

Computational methods can be used to predict or simulate how a specific compound reacts with a given protein target. The means assist to determine everything that chemists need to know about drugs and its future properties, collateral effects and etc. when it will be a remedy. The next three virtual screening or computing methods are applied in the modern medication discovery procedure: Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping.
