Since binding of a drug molecule to human serum albumin (HSA) significantly affects the pharmacokinetics of the drug, it is highly desirable to predict the binding affinity of the drug. Profen drugs are a widely used class of nonsteroidal anti-inflammatory drugs and it has been reported that several members of the profen class specifically bind to one of the main binding sites named site II. The actual binding mode of only ibuprofen has been directly confirmed by X-ray crystallography. Therefore, it is of interest whether other profen drugs are site II binders. Docking simulations using multiple template structures of HSA from three crystal structures of complexes between drugs and HSA have demonstrated that most of the currently available profen drugs should be site II binders.

Human Serum Albumin (HSA) predominantly found in the blood plasma proteins, acts as a carrier for many drugs. In the present work binding interactions of eight arylpropionate non-steroidal anti-inflammatory drugs (NSAIDs) were studied with Human Serum Albumin HSA using Capillary Electrophoresis (CE) under physiological conditions. The concentration of HSA was kept constant (525 μM) whereas the drug concentrations were varied between 50-300 μM in each case. The Frontal analysis (FA) and Capillary Zone Electrophoresis (CZE) modes of CE were applied together with a mathematical modelling of the experimental results with a view to obtaining pharmacokinetic properties of each drug. The binding order of the drugs to HSA were established with the three methods together with the mathematical approach. Our studies revealed the presence of more than one binding sites for some of the available drugs. Additionally, molecular docking studies were conducted to establish the binding conformations of drugs in the binding pocket of the HSA. A very good correlation between the computed binding energies (docking) and the experimental binding constants were observed throughout this study. The logK values for all eight drugs were ranging from 3.37 - 4.56 for FA, 3.16 – 4.39 for CZE, and 3.48 – 5.30 for computational studies.

Human serum albumin (HSA) plays a fundamental role in the human body. It takes part in the transport of exogenic and endogenic substances, especially drugs. Ibuprofen (IBU) is one of the most commonly used non-steroidal anti-inflammatory drugs, used for pain relief, fever relief, and for anti-inflammatory purposes. The binding of ligands with HSA is a significant factor which determines the toxicity and the therapeutic dosages of these substances. The aim of this study was to compare the degree of ibuprofen binding with human serum albumin at various temperatures and protein solution pH values. In order to evaluate conformational changes in HSA caused by interaction with ibuprofen, spectrophotometric (first and second derivatives of the UV-VIS spectrum), and spectrofluorometric analyses were performed concerning the mutual interactions of IBU-HSA. The use of fluorescent spectroscopy allowed for recording fluorescent emissive spectra of HSA (5 × 10−6 mol/dm3) without and with the presence of ibuprofen (1 × 10−5–1 × 10−4 mol/dm3) at temperatures of 308, 310, 312, and 314 K at pH values of 6.5, 6.8, 7.4, 7.8, and 8.1. System fluorescence was excited by radiation of wavelengths of λex = 275 nm and λex = 295 nm. Based on this, original and modified Stern-Volmer, Scatchard, Klotz and Hill curves were determined. The data that were obtained showed a significant effect of temperature and pH of the human serum albumin solution on the strength and type of interaction of ibuprofen with HSA.
