Optibrium, a developer of software for drug discovery, has announced the launch of version 6.1 of its StarDrop platform to guide researchers in the design of high quality compounds in drug discovery, agrochemicals and other chemistry fields. The latest release introduces the Matsy™ technology, based on matched molecular series analysis, which proposes strategies for chemical substitutions to optimise compound activity. Also included is a major upgrade to StarDrop’s P450 metabolism module that facilitates the design of compounds with improved metabolic stability, in addition to enhancements to the platform’s data analysis and management capabilities.

As a result of Optibrium’s collaboration with NextMove Software, the addition of the Matsy algorithm extends the capabilities of StarDrop’s Nova™ module that automatically generates and prioritises novel compound ideas. Matsy searches databases of matched molecular series to identify chemical substitutions that are most likely to improve target activity. Using data from longer series of matched compounds, instead of the common matched molecular pairs approach, provides additional context and enables more relevant predictions to be made for a chemical series of interest. The combination with StarDrop’s unique capabilities for multi-parameter optimisation and predictive modelling enables efficient prioritisation of the resulting ideas to identify high quality compounds with the best chance of success.

StarDrop’s P450 module uses quantum mechanical methods to predict the most likely sites of metabolism on a compound by drug metabolising isoforms of Cytochrome P450 and guides the design of compounds to improve metabolic stability. The major upgrade of this module in StarDrop 6.1 offers further improvements in the accuracy of existing isoform models (CYP3A4, CYP2D6, CYP2C9) as well as adding new models (CYP2C8, CYP2C19, CYP2E1, CYP1A2). The corresponding metabolite structures are also predicted to assist analysis of their properties and guide metabolite identification. This research was undertaken as part of the HeCaToS project, funded under the European Union Seventh Framework Programme (grant agreement 602156).

Dr Matthew Segall, Optibrium’s CEO, commented: “We are delighted to announce another significant upgrade to StarDrop, further expanding its predictive capabilities and building on the success of StarDrop 6’s ground-breaking Card View™. These developments enhance StarDrop’s already comprehensive environment for compound design and selection to guide chemistry projects to successful outcomes.”

StarDrop 6.1 is previewed at the American Chemical Society National Meeting, 22nd-26th March 2015, in Denver with demonstrations on booth #1219.
