Why get excited about virtual discovery ?

Laboratory based discovery

Expensive

Long setup stage, slow experiments

Compounds and assays degrade

Laboratory infrastructure

Chemistry space is defined by access to physical compounds

Virtual discovery

Cheap

Immediate, rapid experiments

No shelf-life or repeatability issues

No physical infrastructure

Coverage of all accessible chemistry space

Virtual discovery, both rational and high throughput, is playing an ever greater role in the discovery process

3

How does virtual discovery help solve the R&D bottleneck ?

• Genomics and proteomics research has given the world a wealth of potential druggable targets to work on and has started a race to identify appropriate small molecules

• High throughput laboratory chemistry and screening technologies have not been powerful enough to deal with the avalanche of targets

• There is no appetite to scale up physical chemistry and screening beyond current technology limitations

Only virtual techniques, discovering highly profiled candidate molecules for laboratory testing, can address the bottleneck

4

Introducing on-demand in-silico discovery

• The complexity of virtual discovery technology is a major constraint for SMEs - there is an opportunity to provide a complete ASP service for discovery informatics

• Processing requirements for virtual discovery are potentially very large and very irregular – an on-demand facility combining leading edge software and large scale computing power might be highly attractive proposition for companies of all sizes

• The combination of unique virtual discovery technology and massive computing power will create wholly new ways of exploring chemical space

In virtual discovery, the only constraints are the quality of the algorithms and the availability of processing power

5

So, what is the big idea ?

The idea is to allow researchers to buy virtual drug discovery capability on an as-needed basis by plugging their workstations into the internet

You can contribute to making this a reality

At this User Group Meeting, you can participate :

• Discussion about the composition and value of an on-demand virtual discovery centre

• Survey of market interest in such a facility

… or back of envelope design over a beer !

You can contribute to making this a reality

As a partner, you can participate in an exciting new business proposition which already has the interest of a leading global provider of information technology services :

• Help us develop the GUI environment which will provide the entry point to the virtual discovery tools

• Hook in your virtual screening technology (target based virtual screening, ADME/T models etc)

• Be an early adopter and get an opportunity to contribute your particular requirements during the design process

There is a real commercial opportunity to be part of a unique, ground-breaking project
