Free energy methods for pharmaceutical drug discovery

News

Mobley lab highlights since Spring

There’s lots of great news since my last update in April.

Lab news and events:

  • New graduate student Hannah Baumann recently joined the lab, coming to us from Germany after an internship at Merck Group doing free energy calculations. She’s probably done more such calculations than anyone in the lab!
  • Rotation students Martin Amezcua, Oanh Tran, Chris Zhang and Ellie Frank are spending time in the lab this quarter
  • Caitlin Bannan received an NSF MolSSI Phase II Fellowship for her work on direct chemical perception with the Open Force Field Initiative
  • Nathan Lim was awarded an NSF MolSSI Phase I Fellowship for his work on our BLUES software package.

The Open Force Field Consortium launches; check out a webinar

We’re very excited about the Open Force Field Initiative, a new effort to help build better force fields and improve the infrastructure for developing them. And we’re especially excited that a pharmaceutical industry consortium has come together to help fund and guide this work. Check out our announcement for more details!

If you’d like to know more about our longer-term plans, check out graduate student Caitlin Bannan’s upcoming BioExcel Webinar Oct. [More…]

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.

SAMPL6 challenge results from pKa predictions based on a general Gaussian process model

Caitlin C. Bannan, David L. Mobley, A. Geoffrey Skillman

A variety of fields would benefit from accurate pKa predictions, especially drug design due to the affect a change in ionization state can have on a molecules physiochemical properties. Participants in the recent SAMPL6 blind challenge were asked to submit predictions for microscopic and macroscopic pKas of 24 drug like small molecules.

Joint Open Force Field Initiative / XtalPi Distinguished Postdoctoral Fellowship

The Open Force Field Consortium (OpenFF, openforcefield.org) and XtalPi, Inc. (xtalpi.com) seeks a Distinguished Postdoctoral Fellow to perform cutting-edge research in a unique academic-industrial joint effort.

OpenFF is an academic collaboration (based at UC Irvine / UC Davis / UC San Diego / Univ. Colorado Boulder / Sloan Kettering Institute in New York) that seeks to develop next-generation molecular mechanics force fields and associated parameterization software and data infrastructure. [More…]
