And drug development disciplines needed. Overview of 　current drug discovery is simply not only knowledge of medicine, has been satisfied with a deal with a variety of disciplines. For these disciplines, after briefly described the current drug first, we described. After referring to genome science and drug discovery to drug discovery and then a major impact, draws the future prospects for drug discovery. Drug discovery and current. Once a new drug, over a month more than 10 years, has been developed that depend on chance. However, such methods are inefficient, about 10 years ago began a move to make drugs reasonably. Been elucidated from the human genome would be particularly spur movement. The reason became clear that almost complete picture of the human genome, the nature and function of proteins produced by genes, protein-protein interactions and is now able to elucidate the interaction between proteins and genes. In other words, to identify genes and proteins that cause disease, became possible theoretical drug acts directly on them. 　Modern drug development is so closely related with the elucidation of the genome and, if it requires a new discipline about it .
