Challenges in the use of atomistic simulations to predict solubilities of drug-like molecules

Guilherme Duarte Ramos Matos, David L. Mobley

Background: Solubility is a physical property of high importance to the pharmaceutical industry, the prediction of which for potential drugs has so far been a hard task. We attempted to predict the solubility of acetylsalicylic acid (ASA) by estimating the absolute chemical potentials of its most stable polymorph and of solutions with different concentrations of the drug molecule.

Binding modes of ligands using enhanced sampling (BLUES)

BLUES enhances samling of ligand binding modes

Samuel C. Gill, Nathan M. Lim, Patrick B. Grinaway, Ariën S. Rustenburg, Josh Fass, Gregory A. Ross, John D. Chodera and David L. Mobley

 

 

Accurately predicting protein-ligand binding affinities and binding modes is a major goal in computational chemistry, but even the prediction of ligand binding modes in proteins poses major challenges. Here, we focus on solving the binding mode prediction problem for rigid fragments.  [More…]

Plans are coming together for the SAMPL6 challenge

Plans are starting to shape up for the SAMPL6 blind prediction challenge, coming later this year! (Our overall SAMPL initiative is still unfunded and we need your input, but we are able to proceed with SAMPL6).

SAMPL6 will focus on host-guest binding on some familiar systems, as well as logD prediction with known (provided) pKa values for a series of small organic compounds. [More…]

SAMPL testimonials sought

For some time, we’ve been involved with running the SAMPL series of blind challenges focused on driving progress in modeling of physical properties and binding (see also the D3R page and our SAMPL NIH proposal) and recently, we’ve sought support from the NIH for this work. However, this is an unconventional type of proposal for the NIH, since the focus is on driving progress of other people’s methods.  [More…]

Postdoc position currently available (update: filled)

Interested in developing and applying new methods relating to free energy calculations? I have a postdoc position which just opened up in this area, working with OpenMM to advance binding free energy techniques and apply/validate them on problems relating to drug discovery. This is an NIH-funded project (1R01GM108889-01) and interfaces closely with other work going on in the group and elsewhere. [More…]
