Predictive In Silico Models in Drug Discovery and Development
26 March - 27 March 2003
Predictive <i>In Silico Models</i> in Drug Discovery and Development

The conference will look at computational (in silico) and biochemical approaches to understanding how a lead drug candidate will interact with cells and eventually how the organism will react to particular drugs. Reliable predictive analytical models could be the key to cutting the costs and time involved in drug discovery/development.

This is an area that is really still in its infancy but all big pharma are keen to implement systems to be at the cutting edge and minimize unnecessary expenditure on drug candidates that are not going to make it through clinical trials.

The conference will look at design, implementation, use and validation of systems to model cell and eventually organism reaction to drugs or conditions. These can then be used to predict how a drug will work and what the likely side effects will be.

STRUCTURAL-NEUTRAL MODELS FOR PROTEIN INTERACTIONS

Dr Jonathon Swinton

Dr Jonathon Swinton, Senior Computational Biologist, Proteom

  • In silico drug design is beginning to work for targets of known structure with small ‘pockets’
  • However, huge numbers of processes are mediated by protein-protein interactions, which have historically been considered intractable
  • Many key drug targets do not, in any case, even have well characterised structures and discovery has proceeded by screening techniques
  • There is opportunity for techniques of wider validity than docking but higher efficiency than random screening
  • We describe recent developments in these structure-neutral techniques which can exploit but do not require specific structural data
  • We give examples from binding site prediction, peptide ligand design, and protein interaction network prediction

    WEEDING OUT COMPLEX NETWORKS TO FIND DRUG TARGETS

    Dr Eric Werner

    Dr Eric Werner, President, Cellnomica

  • Genomic networks are a formidable challenge
  • The key is to understand the meaning of such networks in function and dynamics of multicellular systems
  • In silico modelling of multicellular dynamic systems can help us in the understanding of genome networks
  • When genomic networks are better understood, it positions us to weed out the complexity to find essential drug targets
  • We will discuss in silico systems developed at Cellnomica that model networks causing in silico multicellular diseases such as cancer
  • This will bring us closer to the discovery of natural genomic networks and their role in disease

    WHAT IS CPD?

    CPD stands for Continuing Professional Development’. It is essentially a philosophy, which maintains that in order to be effective, learning should be organised and structured. The most common definition is:

    ‘A commitment to structured skills and knowledge enhancement for Personal or Professional competence’

    CPD is a common requirement of individual membership with professional bodies and Institutes. Increasingly, employers also expect their staff to undertake regular CPD activities.

    Undertaken over a period of time, CPD ensures that educational qualifications do not become obsolete, and allows for best practice and professional standards to be upheld.

    CPD can be undertaken through a variety of learning activities including instructor led training courses, seminars and conferences, e:learning modules or structured reading.

    CPD AND PROFESSIONAL INSTITUTES

    There are approximately 470 institutes in the UK across all industry sectors, with a collective membership of circa 4 million professionals, and they all expect their members to undertake CPD.

    For some institutes undertaking CPD is mandatory e.g. accountancy and law, and linked to a licence to practice, for others it’s obligatory. By ensuring that their members undertake CPD, the professional bodies seek to ensure that professional standards, legislative awareness and ethical practices are maintained.

    CPD Schemes often run over the period of a year and the institutes generally provide online tools for their members to record and reflect on their CPD activities.

    TYPICAL CPD SCHEMES AND RECORDING OF CPD (CPD points and hours)

    Professional bodies and Institutes CPD schemes are either structured as ‘Input’ or ‘Output’ based.

    ‘Input’ based schemes list a precise number of CPD hours that individuals must achieve within a given time period. These schemes can also use different ‘currencies’ such as points, merits, units or credits, where an individual must accumulate the number required. These currencies are usually based on time i.e. 1 CPD point = 1 hour of learning.

    ‘Output’ based schemes are learner centred. They require individuals to set learning goals that align to professional competencies, or personal development objectives. These schemes also list different ways to achieve the learning goals e.g. training courses, seminars or e:learning, which enables an individual to complete their CPD through their preferred mode of learning.

    The majority of Input and Output based schemes actively encourage individuals to seek appropriate CPD activities independently.

    As a formal provider of CPD certified activities, SAE Media Group can provide an indication of the learning benefit gained and the typical completion. However, it is ultimately the responsibility of the delegate to evaluate their learning, and record it correctly in line with their professional body’s or employers requirements.

    GLOBAL CPD

    Increasingly, international and emerging markets are ‘professionalising’ their workforces and looking to the UK to benchmark educational standards. The undertaking of CPD is now increasingly expected of any individual employed within today’s global marketplace.
