The Extent Of Perturbation Of Skin Models By Transdermal Penetration Enhancers Investigated By 31p Nmr And Fluorescence Spectroscopy, Charmita Patricia Burch

Chemistry Dissertations

The molecular basis of the potent transdermal enhancement activity of a series of iminosulfuranes, structure provided where X = H, Cl, Br, and I, is being investigated skin models. It has been shown (J. Lipid Res. 46(2005), 2192-2201.) that correlations exist between the activity of the aforementioned transdermal penetration enhancers (TPE) and the extent to which these agents bind to DMPC vesicles and perturb the gel to liquid crystal phase transition measured by calorimetry. The degree to which the perturbation of these compounds extends into the bilayer interior in contrast to surface activity is unclear. To gain insight into this …
