Interpretation of Quantitative Structure-Activity Relationship Models: Past, Present, and Future.

Journal of chemical information and modeling

Polishchuk P.
PMID: 28949520
J Chem Inf Model. 2017 Nov 27;57(11):2618-2639. doi: 10.1021/acs.jcim.7b00274. Epub 2017 Oct 13.

This paper is an overview of the most significant and impactful interpretation approaches of quantitative structure-activity relationship (QSAR) models, their development, and application. The evolution of the interpretation paradigm from "model → descriptors → (structure)" to "model → structure"...

An Additive Definition of Molecular Complexity.

Journal of chemical information and modeling

Böttcher T.
PMID: 26857537
J Chem Inf Model. 2016 Mar 28;56(3):462-70. doi: 10.1021/acs.jcim.5b00723. Epub 2016 Feb 22.

A framework for molecular complexity is established that is based on information theory and consistent with chemical knowledge. The resulting complexity index Cm is derived from abstracting the information content of a molecule by the degrees of freedom in...

What is the smallest saturated acyclic alkane that cannot be made?.

Journal of chemical information and modeling

de Silva KM, Goodman JM.
PMID: 15667132
J Chem Inf Model. 2005 Jan-Feb;45(1):81-7. doi: 10.1021/ci0497657.

Saturated acyclic alkanes may show a high degree of strain if they have many branches close to each other. We report calculations which indicate how strained a molecule may become before it falls apart rapidly at room temperature and...

Linear and nonlinear methods in modeling the aqueous solubility of organic compounds.

Journal of chemical information and modeling

Catana C, Gao H, Orrenius C, Stouten PF.
PMID: 15667142
J Chem Inf Model. 2005 Jan-Feb;45(1):170-6. doi: 10.1021/ci049797u.

Solubility data for 930 diverse compounds have been analyzed using linear Partial Least Square (PLS) and nonlinear PLS methods, Continuum Regression (CR), and Neural Networks (NN). 1D and 2D descriptors from MOE package in combination with E-state or ISIS...

Reaction-MQL: line notation for functional transformation.

Journal of chemical information and modeling

Reisen FH, Schneider G, Proschak E.
PMID: 19090785
J Chem Inf Model. 2009 Jan;49(1):6-12. doi: 10.1021/ci800215t.

Representation of chemical reactions is pivotal for different purposes in cheminformatics. We present an extension of the molecular query language (MQL), which combines readable style with meaningful rules for string representation of reactions and unambiguous product formation. The concept...

Mechanism of the Kolbe-Schmitt reaction. Structure of the intermediate potassium phenoxide-CO(2) complex.

Journal of chemical information and modeling

Marković Z, Marković S, Manojlović N, Predojević-Simović J.
PMID: 17511442
J Chem Inf Model. 2007 Jul-Aug;47(4):1520-5. doi: 10.1021/ci700068b. Epub 2007 May 19.

Our investigation elucidates the structure of the intermediate in the first stage of the carboxylation reaction of potassium phenoxide. Under the reduced pressure of carbon dioxide the complex is not solvated with the CO(2) molecules. Under the conditions of...

Kohonen network study of aromatic compounds based on electronic and nonelectronic structure descriptors.

Journal of chemical information and modeling

Panek JJ, Jezierska A, Vracko M.
PMID: 15807487
J Chem Inf Model. 2005 Mar-Apr;45(2):264-72. doi: 10.1021/ci049752t.

Atoms in Molecules (AIM) and Electron Localization Function (ELF) methodologies were applied to describe the electronic structure of 88 aromatic compounds. The analyzed database contains molecules substituted by nucleophilic and electrophilic groups which are responsible for electron density distribution...

Chemical markup, XML, and the world wide web. 6. CMLReact, an XML vocabulary for chemical reactions.

Journal of chemical information and modeling

Holliday GL, Murray-Rust P, Rzepa HS.
PMID: 16426051
J Chem Inf Model. 2006 Jan-Feb;46(1):145-57. doi: 10.1021/ci0502698.

A set of components (CMLReact) for managing chemical and biochemical reactions has been added to CML. These can be combined to support most of the strategies for the formal representation of reactions. The elements, attributes, and types are formally...

Simultaneous feature selection and parameter optimisation using an artificial ant colony: case study of melting point prediction.

Chemistry Central journal

O'Boyle NM, Palmer DS, Nigsch F, Mitchell JB.
PMID: 18959785
Chem Cent J. 2008 Oct 29;2:21. doi: 10.1186/1752-153X-2-21.

BACKGROUND: We present a novel feature selection algorithm, Winnowing Artificial Ant Colony (WAAC), that performs simultaneous feature selection and model parameter optimisation for the development of predictive quantitative structure-property relationship (QSPR) models. The WAAC algorithm is an extension of...

PMID: 16309286
J Chem Inf Model. 2005 Nov-Dec;45(6):1791-803. doi: 10.1021/ci050056i.

We discuss models fit to data collected by Duffy and Jorgensen to predict solvation free energies and partition equilibria of drugs, organic molecules, aromatic heterocycles, and other molecules. These data were originally examined using linear regression, but here more...
