In this study the effect of phloretin (PH) and 6-ketocholestanol (KC) on the permeation of progesterone through porcine skin has been examined. Both PH and KC were incorporated into unilamellar L-alpha-phosphatidylcholine (PC) liposomes at different concentrations (7.5, 15, 30 and

The aim of this study was to investigate membrane interactions of phloretin and 6-ketocholestanol using different methods. A previously reported colorimetric assay with phospholipid/polydiacetylene (PDA) vesicles was used to examine a possible interaction of phloretin and 6-ketocholestanol with this target.

As a result of the interfacial chemical heterogenity, membrane-penetrating peptides will experience a dramatic variation in environmental polarity manifested via electrical interactions with the surface and dipole potential of membranes prone to modulate the membrane insertion and folding of different
Nitro-2,1,3-benzoxadiazol-4-yl (NBD) group is a widely used, environment-sensitive fluorescent probe. The negatively charged dithionite rapidly reduces the accessible NBD-labeled lipids in liposomes to their corresponding nonfluorescent derivatives. In this study both the phospholipid headgroup and acyl chain NBD-labeled L-alpha-1,2-dipalmitoyl-sn-glycero-3-phospho-[N-(4-nitrobenz-2-oxa-1,3-diazole)-ethanolamine] (DPPN)
Membrane microdomains, such as caveolae and rafts, are enriched in cholesterol and sphingomyelin, display liquid-ordered phase properties, and putatively function as protein organizing platforms. The goal of this investigation was to identify sterol and sphingomyelin structural features that modulate surface
