The BLUES Report: Towards fragment binding mode occupancies

Tue, 13 Mar 2018 00:00:00 +0000

This is a talk/status report given on our BLUES technique for estimating fragment binding mode occupancies; it was presented at the OpenEye CUP Meeting in Santa Fe, NM, March 8, 2018. This work is in the area of structure-based drug design and we are working on modeling techniques to efficiently estimate populations of metastable ligand binding modes. The presentation is made available in PowerPoint and Keynote formats and includes movies, so the files are large.

The Guthrie Hydration Free Energy Database of Experimental Small Molecule Hydration Free Energies

Wed, 7 Mar 2018 00:00:00 +0000

This provides access to the late J. Peter Guthrie's small molecule hydration free energy database, which was donated posthumously to the community. This is an archival copy of material also maintained on GitHub at https://github.com/mobleylab/GuthrieSolv. If you are interested in using the data provided here, please read the relevant background information and disclaimers provided in the included README.md file, and consider contributing to curation of the dataset.

Predicting binding free energies: Frontiers and benchmarks (a perpetual review)

Mon, 21 Aug 2017 00:00:00 +0000

Binding free energy calculations based on molecular simulations provide predicted affinities for biomolecular complexes.These calculations begin with a detailed description of a system, including its chemical composition and the interactions between its components.Simulations of the system are then used to compute thermodynamic information, such as binding affinities.Because of their growing promise for guiding molecular design, these calculations have recently begun to see widespread applications in early stage drug discovery.However, many challenges remain to make them a robust and reliable tool. Here, we highlight key challenges facing these calculations, describe known examples of these challenges, and call for the designation of standard community benchmark test systems that will help the research community generate and evaluate progress.In our view, progress will require careful assessment and evaluation of new methods, force fields, and modeling innovations on well-characterized...

Experimental and Calculated Small Molecule Hydration Free Energies

Fri, 24 Jan 2014 00:00:00 +0000

This work provides a curated database of experimental and calculated hydration free energies for small molecules in water, along with experimental values and input files. Experimental values are taken from prior literature and will continue to be curated, with updated experimental references and data added as it becomes available. Calculated values are based on the GAFF small molecule force field in TIP3P water with AM1-BCC charges, as in the provided parameter files. Values were calculated using the GROMACS simulation package, with full details given in references cited within the database itself. This database builds on previous work from the Mobley lab and others, and extends the prior database. With deposition in eScholarship, the database is now versioned, allowing citation of specific versions of the database, and easier updates.

A change log is provided in the PDF file associated with each version.
