Milk-Derived Carbon Quantum Dots: Study of Biological and Chemical Properties Provides Evidence of Toxicity

Molecules, 2022
Carbon dots (CDs) are carbon-based zero-dimensional nanomaterials that can be prepared from a number of organic precursors. In this research, they are prepared using fat-free UHT cow milk through the hydrothermal method.

Computational Approach to Drug Penetration across the Blood-Brain and Blood-Milk Barrier Using Chromatographic Descriptors

Cells, 2023
Drug penetration through biological barriers is an important aspect of pharmacokinetics. Although the structure of the blood-brain and blood-milk barriers is different, a connection can be found in the literature between drugs entering the central ...

Revisiting the Rate-Limiting Step of the ANS–Protein Binding at the Protein Surface and Inside the Hydrophobic Cavity

Molecules, 2021
8-Anilino-1-naphthalenesulfonic acid (ANS) is used as a hydrophobic fluorescence probe due to its high intensity in hydrophobic environments, and also as a microenvironment probe because of its unique ability to exhibit peak shift and intensity change ...

Unraveling Hepcidin Plasma Protein Binding: Evidence from Peritoneal Equilibration Testing

Pharmaceuticals, 2019
Peptide hormone hepcidin regulates systemic iron metabolism and has been described to be partially bound to α2-macroglobulin and albumin in blood. However, the reported degree of hepcidin protein binding varies between <3% and ≈89%.

Phosphate‐binding sequences in nucleotide‐binding proteins [PDF]

FEBS Letters, 1985
In the three‐dimensional model of adenylate kinase, the phosphate‐binding site for AMP and ATP has been identified [Pai, E.F. et al. (1977) J. Mol. Biol. 114, 37‐45]. In this region one can distinguish a sequence glycine XXXX glycinelysine. The same sequence is found in many other mononucleotide‐binding proteins including elongation factors and ...

Chemical Attachment of 5-Nitrosalicylaldimine Motif to Silatrane Resulting in an Organic–Inorganic Structure with High Medicinal Significance

Pharmaceutics, 2022
Two chemical motifs of interest for medicinal chemistry, silatrane as 1-(3-aminopropyl) silatrane (SIL M), and nitro group attached in position 5 to salicylaldehyde, are coupled in a new structure, 1-(3-{[(2-hydroxy-5-nitrophenyl)methylidene]amino}propyl)

A Kinetic Transition Network Model Reveals the Diversity of Protein Dimer Formation Mechanisms

Biomolecules, 2023
Protein homodimers have been classified as three-state or two-state dimers depending on whether a folded monomer forms before association, but the details of the folding–binding mechanisms are poorly understood.

Effect of hypoalbuminemia on drug pharmacokinetics

Frontiers in Pharmacology
Hypoalbuminemia, defined as serum albumin levels below 35 g/L, is common in patients with conditions such as nephrotic syndrome, cirrhosis, or sepsis. This review examines the impact of hypoalbuminemia on the pharmacokinetics of selected drugs—such as ...

Largazole Pharmacokinetics in Rats by LC-MS/MS

Marine Drugs, 2014
A highly sensitive and specific LC-MS/MS method for the quantitation of largazole thiol, the active species of the marine-derived preclinical histone deacetylase inhibitor, largazole (prodrug), was developed and validated.
