Metabolic Forest: Predicting the Diverse Structures of Drug Metabolites.

Journal of chemical information and modeling

Hughes TB, Dang NL, Kumar A, Flynn NR, Swamidass SJ.
PMID: 32881497
J Chem Inf Model. 2020 Oct 26;60(10):4702-4716. doi: 10.1021/acs.jcim.0c00360. Epub 2020 Sep 16.

Adverse drug metabolism often severely impacts patient morbidity and mortality. Unfortunately, drug metabolism experimental assays are costly, inefficient, and slow. Instead, computational modeling could rapidly flag potentially toxic molecules across thousands of candidates in the early stages of drug...

XenoNet: Inference and Likelihood of Intermediate Metabolite Formation.

Journal of chemical information and modeling

Flynn NR, Dang NL, Ward MD, Swamidass SJ.
PMID: 32525671
J Chem Inf Model. 2020 Jul 27;60(7):3431-3449. doi: 10.1021/acs.jcim.0c00361. Epub 2020 Jun 29.

Drug metabolism is a common cause of adverse drug reactions. Drug molecules can be metabolized into reactive metabolites, which can conjugate to biomolecules, like protein and DNA, in a process termed bioactivation. To mitigate adverse reactions caused by bioactivation,...

Modeling Epoxidation of Drug-like Molecules with a Deep Machine Learning Network.

ACS central science

Hughes TB, Miller GP, Swamidass SJ.
PMID: 27162970
ACS Cent Sci. 2015 Jul 22;1(4):168-80. doi: 10.1021/acscentsci.5b00131. Epub 2015 Jun 09.

Drug toxicity is frequently caused by electrophilic reactive metabolites that covalently bind to proteins. Epoxides comprise a large class of three-membered cyclic ethers. These molecules are electrophilic and typically highly reactive due to ring tension and polarized carbon-oxygen bonds....

Continuity, divergence, and the evolution of brain language pathways.

Frontiers in evolutionary neuroscience

Rilling JK, Glasser MF, Jbabdi S, Andersson J, Preuss TM.
PMID: 22319495
Front Evol Neurosci. 2012 Jan 03;3:11. doi: 10.3389/fnevo.2011.00011. eCollection 2011.

Recently, the assumption of evolutionary continuity between humans and non-human primates has been used to bolster the hypothesis that human language is mediated especially by the ventral extreme capsule pathway that mediates auditory object recognition in macaques. Here, we...

Fast electron paramagnetic resonance magic angle spinning simulations using analytical powder averaging techniques.

The Journal of chemical physics

Saliba EP, Barnes AB.
PMID: 31542017
J Chem Phys. 2019 Sep 21;151(11):114107. doi: 10.1063/1.5113598.

Simulations describing the spin physics underpinning nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) spectroscopy play an important role in the design of new experiments. When experiments are performed in the solid state, samples are commonly composed of...

A Representational Similarity Analysis of Cognitive Control during Color-Word Stroop.

The Journal of neuroscience : the official journal of the Society for Neuroscience

Freund MC, Bugg JM, Braver TS.
PMID: 34162756
J Neurosci. 2021 Sep 01;41(35):7388-7402. doi: 10.1523/JNEUROSCI.2956-20.2021. Epub 2021 Jun 23.

Progress in understanding the neural bases of cognitive control has been supported by the paradigmatic color-word Stroop task, in which a target response (color name) must be selected over a more automatic, yet potentially incongruent, distractor response (word). For...

Journal of chemical information and modeling

Flynn NR, Dang NL, Ward MD, Swamidass SJ.
PMID: 32525671
J Chem Inf Model. 2020 Jul 27;60(7):3431-3449. doi: 10.1021/acs.jcim.0c00361. Epub 2020 Jun 29.

Modeling Reactivity to Biological Macromolecules with a Deep Multitask Network.

ACS central science

Hughes TB, Dang NL, Miller GP, Swamidass SJ.
PMID: 27610414
ACS Cent Sci. 2016 Aug 24;2(8):529-37. doi: 10.1021/acscentsci.6b00162. Epub 2016 Jul 29.

Most small-molecule drug candidates fail before entering the market, frequently because of unexpected toxicity. Often, toxicity is detected only late in drug development, because many types of toxicities, especially idiosyncratic adverse drug reactions (IADRs), are particularly hard to predict...

Informatics and data mining tools and strategies for the human connectome project.

Frontiers in neuroinformatics

Marcus DS, Harwell J, Olsen T, Hodge M, Glasser MF, Prior F, Jenkinson M, Laumann T, Curtiss SW, Van Essen DC.

Front Neuroinform. 2011 Jun 27;5:4. doi: 10.3389/fninf.2011.00004. eCollection 2011.

The Human Connectome Project (HCP) is a major endeavor that will acquire and analyze connectivity data plus other neuroimaging, behavioral, and genetic data from 1,200 healthy adults. It will serve as a key resource for the neuroscience research community,...

High-Resolution Identification of Specificity Determining Positions in the LacI Protein Family Using Ensembles of Sub-Sampled Alignments.

PloS one

Sloutsky R, Naegle KM.
PMID: 27681038
PLoS One. 2016 Sep 28;11(9):e0162579. doi: 10.1371/journal.pone.0162579. eCollection 2016.

Since the advent of large-scale genomic sequencing, and the consequent availability of large numbers of homologous protein sequences, there has been burgeoning development of methods for extracting functional information from multiple sequence alignments (MSAs). One type of analysis seeks...
