The breast anticancer drug tamoxifen and its metabolites bind serum albumins. We located the binding sites of tamoxifen, 4-hydroxytamoxifen and endoxifen on bovine serum albumin (BSA). FTIR, CD and fluorescence spectroscopic methods as well as molecular modeling were used to characterize the drug binding mode, binding constant and the effect of drug binding on BSA stability and conformation. Structural...
Tamoxifen is extensively metabolized, and several metabolites have been detected in human serum. The aim of this study was to examine the interaction of human serum albumin (HSA) with tamoxifen and its metabolites 4-hydroxytamoxifen and endoxifen at physiological conditions, using constant protein concentration and various drug contents. FTIR, UV–Visible, CD and fluorescence spectroscopic methods...
