Ekins S, Clark AM, Swamidass SJ, Litterman N, Williams AJ.
PMID: 24943138
J Comput Aided Mol Des. 2014 Oct;28(10):997-1008. doi: 10.1007/s10822-014-9762-y. Epub 2014 Jun 19.

Over the past decade we have seen a growth in the provision of chemistry data and cheminformatics tools as either free websites or software as a service commercial offerings. These have transformed how we find molecule-related data and use...

Bioactivation of Isoxazole-Containing Bromodomain and Extra-Terminal Domain (BET) Inhibitors.

Metabolites

Flynn NR, Ward MD, Schleiff MA, Laurin CMC, Farmer R, Conway SJ, Boysen G, Swamidass SJ, Miller GP.
PMID: 34203690
Metabolites. 2021 Jun 15;11(6). doi: 10.3390/metabo11060390.

The 3,5-dimethylisoxazole motif has become a useful and popular acetyl-lysine mimic employed in isoxazole-containing bromodomain and extra-terminal (BET) inhibitors but may introduce the potential for bioactivations into toxic reactive metabolites. As a test, we coupled deep neural models for...

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....

Erratum: Inhibition of DNA Methyltransferases Blocks Mutant Huntingtin-Induced Neurotoxicity.

Large scale study of multiple-molecule queries.

Journal of cheminformatics

Nasr RJ, Swamidass SJ, Baldi PF.
PMID: 20298525
J Cheminform. 2009 Jun 04;1(1):7. doi: 10.1186/1758-2946-1-7.

BACKGROUND: In ligand-based screening, as well as in other chemoinformatics applications, one seeks to effectively search large repositories of molecules in order to retrieve molecules that are similar typically to a single molecule lead. However, in some case, multiple...

Modeling Reactivity to Biological Macromolecules with a Deep Multitask Network.

ACS central science

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...

Deep Learning Coordinate-Free Quantum Chemistry.

The journal of physical chemistry. A

Matlock MK, Hoffman M, Dang NL, Folmsbee DL, Langkamp LA, Hutchison GR, Kumar N, Sarullo K, Swamidass SJ.
PMID: 34609871

Computing quantum chemical properties of small molecules and polymers can provide insights valuable into physicists, chemists, and biologists when designing new materials, catalysts, biological probes, and drugs. Deep learning can compute quantum chemical properties accurately in a fraction of...

Probabilistic Substructure Mining From Small-Molecule Screens.

Molecular informatics

Ranu S, Calhoun BT, Singh AK, Swamidass SJ.

Identifying the overrepresented substructures from a set of molecules with similar activity is a common task in chemical informatics. Existing substructure miners are deterministic, requiring the activity of all mined molecules to be known with high confidence. In contrast,...
