Grid technologies empowering drug discovery.

Grid technologies enable flexible coupling and sharing of computers, instruments and storage. Grids can provide technical solutions to the volume of data and computational demands associated with drug discovery by delivering larger computing capability (flexible resource sharing), providing coordinated access to large data resources and enabling novel online exploration (coupling computing, data and instruments online). Here, we illustrate this potential by describing two applications: the use of desktop PC grid technologies for virtual screening, and distributed X-ray structure reconstruction and online visualization.

Structural pharmacogenomics, drug resistance and the design of anti-infective super-drugs.

Large-scale comparative analysis of drug-target polymorphism structures enables the rational design of next generation 'super drugs'--drugs that are less prone to development of drug resistance or that work for the largest possible fraction of the patient population. Furthermore, knowledge of the drug-target-shape repertoire that exists within the patient population enables predictions of likely clinical trial outcomes and response rates for drug efficacy. This gives information on the optimal drug candidates before the initiation of clinical trials. The economic impact of incorporating pharmacogenomics insights early on in the drug discovery process will be substantial and will afford significant competitive advantages to companies that successfully incorporate this technology.
