abstract = {The interaction of propranolol and acebutolol with
biological membranes was assessed in the present work by
using a range of biophysical techniques and liposomes, as
membrane mimetic models. Liposomes were made of zwitterionic
phosphatidylcholines and experiments were performed at
physiologic pH and at various membrane physical states (gel,
ripple and fluid phases). Fluorescence techniques were used
to study the partition coefficient of β-blockers, the
influence of drugs on membrane fluidity and the
drugs–membrane binding. Moreover, small and wide angle
X-ray scattering techniques were used to evaluate the
β-blockers effect on long range bilayer order and
hydrocarbon chain packing. The gathered results highlighted
the importance of electrostatic interactions between
propranolol and acebutolol with membranes. Furthermore, both
β-blockers exhibited a membrane-fluidizing effect and the
capacity to disturb the membrane organization. In general,
propranolol unveiled a more pronounced effect on membrane
fluidity and structure than acebutolol. In the current
study, the obtained results were also correlated with the
cardioprotective properties of the β-blockers studied.},
