Abstract
We have investigated the effect on dimyristoyl phosphatidylcholine bilayers of pentoxifylline, a derivative of xanthine by using two optical techniques, quasi-elastic light scattering (QLS) and Fourier transform infrared spectroscopy (FT-IR). The results show that in the presence of pentoxifylline, the bilayer phase transition point is lowered and that the elastic modulus is decreased. The FT-IR results indicate strong interactions in the aqueous interface regions of the bilayers. We discussed these results comparatively with those obtained from flavonoid derivatives whose effect was analogous and previously studied.
