2 Introduction – Joe Mernagh 15 Years Cap Gemini Consultant: knowledge systems, IT strategy, Life Sciences R&D Senior Manager Life Sciences Global Management Unit 4 years Evotec OAI Chief Knowledge Officer Executive manager responsible for Knowledge Management and IT Innovative drug discovery solutions Active Dynamics Independent consultant and interim manager Focus on companies involved in drug discovery Projects with potential for long term value creation

3 Why get excited about virtual discovery ? Virtual discovery, both rational and high throughput, is playing an ever greater role in the discovery process Virtual discovery Cheap Immediate, rapid experiments No shelf-life or repeatability issues No physical infrastructure Coverage of all accessible chemistry space Laboratory based discovery Expensive Long setup stage, slow experiments Compounds and assays degrade Laboratory infrastructure Chemistry space is defined by access to physical compounds

4 How does virtual discovery help solve the R&D bottleneck ? Only virtual techniques, discovering highly profiled candidate molecules for laboratory testing, can address the 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

5 Introducing on-demand in-silico discovery In virtual discovery, the only constraints are the quality of the algorithms and the availability of processing power 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

6 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

8 What services might this provide ? Synthesise New Virtual Compounds Find Chemical Route Identify Drug-like Candidates Profile Compounds Design Analogs Design De-novo Compounds Screen Compounds Diversity and Cluster Analysis Find compounds and scaffolds to fit a specific bioavailability and physico-chemical profile What is the pKa, LogD, LogP, polar surface area etc of my compounds ? Input compound - create new, synthetically feasible analogs Fragment based rational design of de-novo compounds Give me a synthetic route and reagents for my selected compounds Create me a new virtual library from my selected reactions and inputs Screen selected compounds for efficacy, ADME and toxicity How chemically diverse are my selected compounds ?
