Residue-based correlation between equilibrium and rate constants is an experimental formulation of the consistency principle for smooth structural changes of proteins [PDF]

open access: yesBiophysics and Physicobiology, 2023
The consistency principle represents a physicochemical condition requisite for ideal protein folding. It assumes that any pair of amino acid residues in partially folded structures has an attractive short-range interaction only if the two residues are in

Allosteric modulators of solute carrier function: a theoretical framework [PDF]

open access: yesFrontiers in Physiology, 2023
Large-scale drug screening is currently the basis for the identification of new chemical entities. This is a rather laborious approach, because a large number of compounds must be tested to cover the chemical space in an unbiased fashion.

Recent Advances in Mediator and Proton Relay Usage in Molecular Catalysis. [PDF]

open access: yesAdv Sci (Weinh)
The use of electron–proton transfer mediators, redox mediators, and proton relays in synergy with molecular catalysts in energy‐related small‐molecule and organic transformations is discussed, with a focus on recent advances. Linear free‐energy relationship and catalytic Tafel plots provide a systematic foundation for benchmarking these catalytic ...

Prediction of Physicochemical Properties of Organic Compounds from 2D Molecular Structure – Fragment Methods vs. LFER Models

open access: yesCHIMIA, 2006
A large number of models is available to predict physicochemical properties directly from the two-dimensional molecular structure. An alternative to conventional fragment methods is given by linear free-energy relationships (LFERs) employing ...

A study of substituent effects on the NH bond in alkyl and aryl 4,6-disubstituted-3-cyano-2-pyridones [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
Substituent effects on the IR stretching frequencies and 1H-NMR chemical shifts of the pyridone NH group in 4- and 6-disubstituted alkyl and aryl 3-cyano- 2-pyridones were investigated.

Substituent effect on IR, 1H and 13C NMR spectral data in n-(substituted phenyl)-2-cyanoacetamides: A correlation study [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2013
Linear free energy relationships (LFER) were applied to the IR, 1H and 13C NMR spectral data of N-(substituted phenyl)-2-cyanoacetamides. A variety of substituents were employed for phenyl substitution and fairly good correlations were obtained using ...

Assessment of atmospheric distribution of polychlorinated biphenyls and polycyclic aromatic hydrocarbons using polyparameter model [PDF]

open access: yesHemijska Industrija, 2011
Results of partial or total destruction of industrial plants, military targets, infrastructure, uncontrolled fires and explosions during the conflict period from 1991 to 1999, at the area of Western Balkans, were large amounts of hazardous organic ...

Anion–π interactions influence pKa values

open access: yesBeilstein Journal of Organic Chemistry, 2011
Five 8-(4-R-phenyl)-1-naphthol derivatives were prepared by PdCl2-catalysed electrophilic aromatic substitution. The pKa' values for these 1,8-disubstituted arene naphthols have been measured in acetonitrile/water (R = NO2, 8.42; R = Cl, 8.52; R = H, 8 ...

Kinetic evaluation of the solvolysis of isobutyl chloro- and chlorothioformate esters

open access: yesBeilstein Journal of Organic Chemistry, 2011
The specific rates of solvolysis of isobutyl chloroformate (1) are reported at 40.0 °C and those for isobutyl chlorothioformate (2) are reported at 25.0 °C, in a variety of pure and binary aqueous organic mixtures with wide ranging nucleophilicity and ...
