Site activation effects promoted by intramolecular hydrogen bond interactions in SNAr reactions
(Royal Society of Chemistry, 2014)
The nucleophilic aromatic substitution reaction of benzohydrazide derivatives towards 2-chloro-5-nitropyrimidine is used as model system to experimentally and theoretically show that intramolecular hydrogen-bond formation ...

How the Nature of an Alpha-Nucleophile Determines a Brønsted Type-Plot and Its Reaction Pathways. An Experimental Study
(2022)
The reactions between 2-chloro-5-nitro pyrimidine with a serie of α-nucleophile derivatives were kinetically evaluated. The kinetic study was carried out in aqueous media and the data shown an unusual split on the Brønsted ...
Conformational Analysis and Intramolecular Interactions in Aminofluorobenzoic Acids

Interaction of O-acylated chitosans with biomembrane models: probing the effects from hydrophobic interactions and hydrogen bonding
(Elsevier BVAmsterdam, 2014-02)
One of the major challenges in establishing the mechanisms responsible for the chitosan action in biomed-ical applications lies in the determination of the molecular-level interactions with the cell membrane. Inthis study, ...
How procyanidin C1 sticks to collagen: The role of proline rings
(Elsevier Science, 2021-09)
Molecular interactions between proteins and polyphenols are responsible for many natural phenomena like colloidal turbidity, astringency, denaturation of enzymes and leather tanning. Although these phenomena are well known, ...
An insight into the thermostability of a pair of xylanases: the role of hydrogen bonds
(TAYLOR & FRANCIS LTD, 2009)
Xylanases are enzymes that are very tolerant to temperature. Their potential use in several biotechnological applications, such as animal food manufacture and pulp bleaching, is due to their intrinsic thermostability. The ...
