Exploring the Discrepancies in the Biological Activities of Extracts From Guadua angustifolia Var. Bicolor Londoño Collected in Two Different Sites

Chemistry &Biodiversity, EarlyView.
ABSTRACT Guadua angustifolia var. bicolor Lodoño is a Colombian bamboo species that has shown promising medicinal properties. This study aims to investigate the differences in the chemical composition and biological activity of extracts from two different populations of G. angustifolia var. bicolor, collected in Bauru and Tatuí, Brazil.

Reactivity of Carbohydrate Phosphodiesters, Potential Targets of Antibacterial Agents

Chemistry &Biodiversity, EarlyView.
A simple carbohydrate phosphodiester model was synthesized to compare the reactivity of phosphodiester bonds within carbohydrates and RNA. ABSTRACT While monosaccharide units in bacterial carbohydrates may be linked with phosphodiester bonds, human carbohydrates exclusively contain glycosidic linkages.

5'-nucleotidases, nucleosides and their distribution in the brain: pathological and therapeutic implications [PDF]

, 2013
Elements of the nucleoside system (nucleoside levels, 5'-nucleotidases (5'NTs) and other nucleoside metabolic enzymes, nucleoside transporters and nucleoside receptors) are unevenly distributed in the brain, suggesting that nucleosides have region ...

Recent Advances in Isatin–Thiazole Hybrids: Synthesis, Structural Design, and Biological Application

Chemistry &Biodiversity, EarlyView.
ABSTRACT Isatin–thiazole hybrids are considered privileged chemical scaffolds due to their broad spectrum of pharmacological properties, making them attractive candidates for drug development. As a result, isatin–thiazole derivatives have emerged as a prominent class of hybrid heterocycles and have been the focus of extensive research in recent years ...

Hybridization Probes Featuring a Pyrenylpyridine C‐Nucleoside or Its Palladacycle as a Fluorescent Sensor Moiety

ChemBioChem, EarlyView.
When placed in the middle of a double helix as a nucleobase surrogate, pyren‐1‐ylpyridine and its palladacyclic derivative show fluorescence emission sensitive to the identity of the canonical nucleobase opposite to it. Emission of the palladacycle is weaker but the base discrimination stronger, possibly because of Pd(II)‐mediated base pairing.
