In this study, the effect of lipophilic counter-ions on the permeation of 5-aminolevulinic acid (ALA) in combination with skin impregnation by phloretin and 6-ketocholestanol was evaluated. Standard in vitro permeation experiments with porcine skin were performed analysing the ALA content

The dipole potential (Psi(d)) constitutes a large and functionally important part of the electrostatic potential of cell plasma membranes. However, its direct measurement is not possible. Herein, new 3-hydroxyflavone fluorescent probes were developed that respond strongly to Psi(d) changes by

Phloretin and 6-ketocholestanol are penetration enhancers for percutaneous delivery of certain topically applied drugs. In the present study some physicochemical experiments have been performed to elucidate the mechanism of action of phloretin and 6-ketocholestanol. The penetration enhancing effect of phloretin

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)
