Polymorphism in the 1/1 Pterostilbene/Picolinic Acid Cocrystal [PDF]
Crystal Growth & Design, 2021 The crystal structures of two new polymorphs of the 1/1 pterostilbene/picolinic acid cocrystal have been analyzed by single-crystal X-ray diffraction and studied by means of DFT calculations and a set of computational tools (QTAIM, NCIplot, MEP). The observation of a new R2 2(10) synthon in each of the two polymorphs has been analyzed energetically ...

Chytridiomycosis of marine diatoms : the role of stress physiology and resistance in parasite-host recognition and accumulation of defense molecules [PDF]
, 2017 Little is known about the role of chemotaxis in the location and attachment of chytrid zoospores to potential diatom hosts. Hypothesizing that environmental stress parameters affect parasite-host recognition, four chytrid-diatom tandem cultures ...

Cytokines and tryptophan metabolites can predict depressive symptoms in pregnancy
Translational Psychiatry, 2022 Depression during and after pregnancy affects up to 20% of pregnant women, but the biological underpinnings remain incompletely understood. As pregnancy progresses, the immune system changes to facilitate fetal development, leading to distinct ...

Solubility and Crystallization Studies of Picolinic Acid
Crystals, 2023 Solubility and crystallization studies of a monocarboxylic derivative of pyridine, picolinic acid (2-pyridinecarboxylic acid), were undertaken as a need for new data in the literature was identified. Moreover, comparative studies of structurally related small molecules, such as these pyridinecarboxylic acid isomers (picolinic acid (PA), nicotinic acid (

3-Hydroxypyridinium-2-carboxylate
Acta Crystallographica Section E, 2011 Comparable to many amino acids, the title compound, C6H5NO3, is a substitution product of picolinic acid. The molecule shows approximate non-crystallographic Cs symmetry. Like many amino acids, the molecule is present in its zwitterionic state. Intra- as

Synthetic strategies for preparing BEDT-TTF derivatives functionalised with metal ion binding groups [PDF]
, 2006 The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups are achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and ...
