Bertucci C., Nanni B., Salvadori P. Reversible binding of ethacrynic acid to human serum albumin: Difference circular dichroism study. In: Chirality, vol. 11 (1) pp. 33 - 38. Wiley, 1999.
The reversible binding of ethacrynic acid was characterized by a difference circular dichroism method. A 2/1 stoichiometry was determined for the [drug]/[HSA] (human serum albumin) complex. The reversible binding of ethacrynic acid to HSA determines direct competition with ligands that selectivity bind to site II and to the fatty acid site. Furthermore, indirect competition was shown for ligands for site I (anticooperative) and to site III (cooperative).
