Exploring the HSA/DNA/lung cancer cells binding behavior of p-Synephrine, a naturally occurring phenyl ethanol amine with anti-adipogenic activity: multi spectroscopic, molecular dynamic and cellular approaches

Binding of Tetrabromobisphenol A and S to Human Serum Albumin Is Weakened by Coexisting Nanoplastics and Environmental Kosmotropes

“…The docking of HSA and BFRs was carried out using the MOE2008.10 (Chemical Computing Ltd., Montreal, Canada) . The structures of HSA and BFRs were taken from the Protein Data Bank (ID: 1AO6, resolution: 2.5 Å) and NCBI (), respectively.…”

“…The docking of HSA and BFRs was carried out using the MOE2008.10 (Chemical Computing Ltd., Montreal, Canada). 29 The structures of HSA and BFRs were taken from the Protein Data Bank (ID: 1AO6, resolution: 2.5 Å) and NCBI (https://pubchem.ncbi.nlm.nih.gov/), respectively. Protonating, tethering and minimizing, and deleting unbound waters were applied to HSA before docking.…”

Interaction of Two Commercial Azobenzene Food Dyes, Amaranth and New Coccine, with Human Serum Albumin: Biophysical Characterization

“…From a structural point of view, the HSA has an asymmetric heart-like shape, with the highest percentage of structural motifs as α-helices. Its tertiary structure contains three homologous α-helical domains: I (residues 1–195), II (196–383), and III (384–585), and each domain is divided into two subdomains (A and B), presenting in each case one feasible binding site to interact with different types of small organic/inorganic compounds. − Since the binding between food dyes and HSA might significantly affect the absorption, distribution, metabolism, and toxicity of not only dyes but also endogenous metabolites or exogenous drugs, a vast literature reported the biophysical interaction between albumin and some azo-food dyes, highlighting the FDA-approved food dyes tartrazine (also known as acid yellow 23), − sunset yellow FCF, − citrus red 2, carmoisine, − allura red AC, − and FDA-unapproved dye ponceau 3R (Figure ). However, there is still not a deep biophysical report on the interaction between HSA and two of the widely used azo-food dyes in the industry: Amaranth and New coccine (E123 and E124, respectively, Figure ), e.g., for Amaranth, there is one report on its interaction with albumins and globulins of soybean and a preliminary interaction with HSA by an electrochemical technique, while for New coccine, there are preliminary reports on its interaction with bovine serum albumin (BSA). , …”

In vitro interactions of esculin and esculetin with bovine hemoglobin alter its structure and inhibit aggregation: insights from spectroscopic and computational studies

“…4 These structural changes can be brought about due to the ability of proteins to interact with other biological molecules and small ligands. 5 This interaction between proteins and small ligands can provide substantial structural and mechanical data for aiding drug discovery development. [6][7][8] Hemoglobin (Hb), an Fe(II) containing polypeptide, is a tetrameric globular protein comprising two ab dimers.…”
