Welwyn Garden City, UK (25th May 2011) - Cresset announces the release of a range of new command-line interfaces and free workflow components for its popular Field based molecular design tools. New command-line interfaces and workflow components have been released for FieldStere, FieldAlign and FieldView. In addition, Cresset has released a number of core tools based on its unique XED force field including XedeX, a Field based conformation hunter, and XedMin, a ligand minimizer that is available for free download.
Rob Scoffin, CEO of Cresset said, “We have worked closely with our customers to understand the changing ways in which they wish to use our applications. Workflow applications such as Pipeline Pilot and KNIME allow flexible deployment and integration of our components into larger workflows and enterprise processes. As part of our support for these platforms we have also released our XED force field tools for the first time to encourage their widespread use.”
The powerful XED force field lies at the heart of Cresset’s unique technology. XED uses off-atom charges to give an improved description of electrostatics, intermolecular interactions and molecular fields. XED’s results have repeatedly been shown to match experimental results more closely than traditional force fields.
XedeX is a ligand conformation explorer based on the XED force field. The performance of XedeX is exceptional, reproducing the ligand bioactive conformation within 100 conformations for the majority of drug-like ligands. XedeX provides you with diverse conformation populations that are energetically accessible, gives excellent control over your conformation generation experiments and conformations that are fully minimized in the XED force field
XedMin enables ligand minimization with the XED force field, giving accurate, experimentally validated intermolecular interactions with correct minimization of pi-pi and cation-pi interactions. It also provides anisotropic charges and polarizability with improved molecular electrostatics.

About Cresset Group Ltd
Cresset develops software for calculating and comparing the molecular Field characteristics of chemical compounds. Field technology uses the surface properties of molecules to evaluate their activities and properties, rather than relying on 2D structure similarity, which enables Cresset’s users to find more interesting, novel and relevant results than other methods. Cresset’s Fields provide a smarter, structure independent way of hit-finding, lead switching and lead optimization in drug discovery and other chemistry-based research projects. Cresset’s Field technologies have been successfully applied to a very wide range of target classes, with and without structural information, on over 100 projects for major pharmaceutical and biotechnology companies. www.cresset-group.com
