June 2011 Newsletter

In this issue we have articles on StarDrop which can accelerate drug discovery through predictive ADMET property prediction, some applications of computational biology, some news, some job vacancies within the modelling community in general, some upcoming meetings of interest to computational chemists and details of our Summer Special Offer.

StarDrops Keep Falling on my Desk!

Born many moons ago, when Inpharmatica was still high in the sky, StarDrop has now grown into a stellar suite of software to aid drug discovery.

Biofocus spin-out Optibrium have been developing the software since 2003, and they have designed the interface with chemists very much in mind.

StarDrop has been developed to help scientists find novel molecules with the required balance of properties to become drug development candidates. StarDrop brings together a variety of computational methods for generating in silico models and analysing data in a user- friendly environment, making it simple to handle uncertainty in the data. One notable innovation is the ‘glowing molecule’ graphic which highlights dynamically the influence of each atom on the modelled properties, allowing medicinal chemists to immediately see the effect of structural changes, and to modify structures whilst monitoring the effects on properties.

The ADMET QSAR plug-in enables calculation of additional properties such as BBB penetration, hERG, P-gp transportation, logD, human intestinal absorption and p450 propensity, although the p450 Metabolism plug-in will predict likely metabolism in much more detail.

The software also comes with tools for diversity assessment and selection, and can be linked with other installed software systems to allow integration with multiple data sources for additional model building and/or visualisation.

Using StarVue, a free molecular visualiser from Optibrium, scientists can share their StarDrop results with others who have no access to the full interface.

CompChem Solutions has recently entered into a collaboration with Optibrium, and is now able to access StarDrop to assist research projects for clients. The software very nicely complements the excellent range of software already accessible to CompChem Solutions, and expands our capabilities in the ADMET prediction area.

Computational Biology – Target Identification for the Future?

Computational biology means many things to many people. I have heard people use the term when referring to biological database management, systems biology, sequence comparison and microarray database analysis. A pretty diverse array of topics I’d say. I think the general consensus, however, is that computational biology attempts to make sense of biological systems.

In terms of new target identification, microarray database analysis must surely be one of the most useful innovations in recent years. Oncomine, for example, now contains over 600,000 sample facts on more than 43k oncology samples, and is available for comparison of gene expression profiles and filtering for “druggable” targets such as kinases. Biological pathway identification, association of diseases with the gene signature of a compound, and identification of pathways regulated by a compound can also be facilitated by use of the database.

Beyond oncology, the MetaCore pathway database from GeneGo contains information on around 4,500 genes, with “causal” gene-disease associations for over 500 human diseases. The system is well set up to aid drug target selection and validation, biomarker identification and patient profiling in clinical trials.

These approaches have already proven their worth in target identification. Indeed, three independent studies using Oncomine have identified SOX2 as the target of recurrent amplification in the 3q26-3q28 chromosomal region associated with squamous cell carcinoma (Nat Genet. 2009 Nov;41(11):1238-42, PLoS One. 2010 Jan 29;5(1):e8960, PLoS One. 2010 Feb 9;5(2):e9112).

With the current drive to identify ever more novel targets, surely the future of target identification will be rooted in computational biology.

News

Susan Boyd of CompChem Solutions is delighted have joined the organising committee of the UK QSAR & Chemoinformatics Group. The group arranges two meetings annually, covering a range of topics relevant to computational medicinal chemistry. If you would be interested in speaking or presenting a poster at a future meeting, would like to host a meeting or have some suggestions for future topics of interest, please contact Susan Boyd.
