Binding of isoquinoline alkaloids berberine, palmatine and coralyne to hemoglobin: structural and thermodynamic characterization studies.
Berberine, palmatine and coralyne, the isoquinoline alkaloids distributed in many botanical families, are extensively investigated due to their potential therapeutic actions and clinical utilities. In this work, their binding characteristics to hemoglobin (Hb) were studied by UV-vis absorption spectroscopy, fluorescence spectroscopy, circular dichroism spectroscopy, isothermal calorimetric titr...
متن کاملBinding of bromosulphthalein to serum albumins.
The binding of bromosulphthalein to human and bovine Serum albumin was studied by infrared spectroscopy, laser-Raman spectroscopy, visible spectroscopy and pH measurements in order to obtain information on the binding forces involved. No conformational change of the proteins was observed during the tight binding of the first three bromosulphthalein molecules as indicated by the kinetics of the ...
متن کاملBINDING OF NAPROXEN TO SERUM PROTEINS IN PATIENTS WITH LIVER CIRRHOSIS AND HEALTHY INDIVIDUALS
A three-fold decrease of the in vitro ability of serum proteins to bind naproxen was shown in patients with cirrhosis of the liver compared to healthy individuals. This decrease was caused by quantitative changes in serum proteins in the sera of patients with liver damage. Lower doses of naproxen are therefore suggested in the treatment of patients with liver dysfunction.
متن کاملSynthesis of isoquinoline and yohimbinoid alkaloids
A systematic survey of the different synthetic methodologies available for the syntheses of isoquinoline and yohimbinoid alkaloids revealed that the general approaches to these compounds involved either an A/B C — D/—i E approach or a D/E — C/B/A approach% We have now devised a novel method for the syntheses of both the isoquinoline and indole alkaloids belonging to the tetra— hydroprotoberberi...
متن کاملBeta-phenylethylamines and the isoquinoline alkaloids.
This review covers beta-phenylethylamines and isoquinoline alkaloids derived from them, including further products of oxidation. condensation with formaldehyde and rearrangement, some of which do not contain an isoquinoline system, together with naphthylisoquinoline alkaloids, which have a different biogenetic origin. The occurrence of the alkaloids, with the structures of new bases, together w...
