The Means of Medicine Investigation These Days

Medication disclosure and development today has a lot of outlooks but in the same moment it is really expensive procedure. The average total cost per medication development varies from US$ 897 million to US$ 1.9 billion. Chemists want usually fifteen years to discover all the specific features of this or that drug. Research and Development of a new medication involves the finding of a target (e.g. protein) and the disclosure of some suitable medication candidates that can block or promote the target. The following stage of the procedure is medical testing that takes a large amount of time and requires governmental approvals for its conducting. Food and Drug Administration (FDA) issues approvals to the medications that would be released in the US. So, drug discovery process is costly and arduous process that takes great pains.

One of the best methods to identify challenging medication candidates is to investigate how the target protein interreacts with randomly selected compounds, which are usually an element of compound list. This examination is usually made in so called high-throughput screening (HTS) facilities. Compound libraries combine a huge number of samples that can achieve several millions. Exemplars that become the most active ones are called hits. Such exemplars wonderfully interact with the target. Some of these hits are then promoted to direct compounds - candidate elements which are refined after that and modified in order to receive better interactions and less collateral effects.

One may see a few different methods of drug design & discovery these days. Below you may see various means for discovering drug candidate where you may also see their advantages and disadvantages:

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

The main advantages of this mode in comparison with laboratory experiments are:

- it is cheap because it doesn’t require any costs for chemists who will make compounds;

- chemists can investigate various compounds that are still in perspective;

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

- a huge number of virtual elements to select from.

Also VS presents really great number of elements that may be utilized in research than HTS represents to chemists. But we must claim about the disadvantage of virtual screening. That is impossibility to observe real interaction of compounds.

2. The real screening, such as high-throughput screening (HTS), can experimentally test the activity of hundreds of thousands of compounds against the target per day. So scientists get genuine outcome during this method of drug discovery. But it requires great costs.

These means show the interaction of a given target (protein) with various elements. It is made for determination the results and chemical features of medication designing and future characteristics of the drug as a medicine. Today scientists apply three main means for virtual screening in drug discovery procedure: Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping.
