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 pK_a 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 pK_as of 24 drug like small molecules.

Recent lab highlights

I’m behind on updates,but there’s a lot of great news recently! Here are some highlights.

Lab news and events:

First year graduate students Danielle Bergazin, Jessica Maat and Noora Siddiqui recently joined the lab. This is in addition to a rotation by Daniel Seith.

We also have great news on the funding front — huge congratulations to Noora, who was just awarded a prestigious DOE CSGF to support her graduate studies! [More…]
