All the Information about Nowadays Medicine Discovery Process

By: Mathew Petrenko

Medication discovery and research is a costly procedure owing to the huge costs of R&D and human clinical experiments. The usual total value per medication development varies from US$ 897 million to US$ 1.9 billion. Scientists want usually fifteen years to research all the specific characteristics of this or that drug. First of all in the development procedure scientists have to identify a target (e.g. protein) and than get different drugs that can interact with the target. Then come clinical experiments that are the most expensive and significant part of the research because it requires to have a great amount of governmental permissions. Food and Drug Administration (FDA) gives endorsements to the medications that would be released in the United States of America. As you may find drug discovery is a high-priced and long process today.

Chemists use the method of interaction the target with various compounds to find the best drug candidate. They take a target protein and watch at the reaction of it with compounds that they have in particular compound list. This examination is usually made in so called high-throughput screening (HTS) technologies. Compound lists contain a large amount of samples that may reach several thousands. There are some exemplars that show brilliant outcome with communicating the target. These are successful exemplars and chemists usually call them hits. Some of these hits are then encouraged to direct compounds - candidate structures which are further refined and modified in order to get better interactions and less side-effects.

You can find several different methods of drug design today. The following are methods for finding a medication candidates, along with their advantages and disadvantages:

1. Virtual screening (VS) founded on the computationally deduced or simulated genuine screening;

The advantages that were observed during the experiments are:

- low prices, no compounds have to be bought externally or created by a scientist;

- scientists can research various compounds that are still in project;

- High-throughput screening is rather expensive and VS gives an opportunity to choose a number of helpful compounds for following HTS tests;

- a huge number of virtual elements to select from.

The number of probable virtual molecules available for virtual screening is exceedingly higher than the quantity of compounds that are accessible for high-throughput screening. But the main shortage is that the procedure is not genuine and it may not show all that can be observed during the real screening.

2. High-throughput method (HTS) is considered to be a real screening and it may investigate the interaction of thousands of elements each day. With the assistance of this mode chemists have real outcomes of their researches. However, it is really high-priced.

The means of investigation are used to detect how a given element interacts with a target. They can be used to help build theories about required chemical properties when creating the drug and, besides, they can be utilized to improve and modify drug candidates. Today chemists use three basic means for virtual screening in medication discovery procedure: Molecular Docking, Quantitative Structure-Activity Relationships (QSAR) and Pharmacopoeia Mapping.
