Investigating the SAR of XIAP ligands with Electrostatic Complementarity maps and scores

In this case study, we used the Electrostatic Complementarity maps available in Flare to investigate the protein-ligand electrostatic interactions and the SAR of a set of inhibitors of the X-linked IAP (XIAP)-caspase protein-protein interaction. Electrostatic Complementarity scores calculated with Flare were used to quantitatively model XIAP-BIR3 pIC50.


Outstanding new 3D graphics in Spark V10.5.5

A new patch level release of Spark™, our scaffold hopping and bioisostere replacement application, is now available. Spark 10.5.5 includes improvements to the look and feel, rendering and performance of the graphics of the 3D window. Customers will receive the download link soon.

Modeling ‘big’: Applying the XED force field to biologics

Cresset is well known for powerful and accurate ligand-centric modeling, and Flare has established our methods for protein-ligand interactions. Work on GPCR modeling and viruses demonstrates the effectiveness and potential of Cresset technology for protein-protein interactions. Martin Slater, Director of Consulting Services, discusses the successes and challenges of modeling ‘big’ – applying Cresset’s XED force field to biologics.
