In the last years, the decreasing effectiveness of conventional antimicrobial-drugs has caused serious problems due to the rapid emergence of multidrug-resistant pathogens. This situation has brought attention to other antimicrobial agents like antim

Interaction of Phenylalanine with DPPC Model Membranes: More Than a Hydrophobic Interaction

Autor: Antonio Sebastián Rosa, María de los Ángeles Frías, Edgardo Anibal Disalvo, Andrea Carmen Cutró

Publikováno v: The Journal of Physical Chemistry B. 119:15844-15847

The negative free energy previously reported is explained by the stabilization of a PC-Phe (phosphocholine-phenylalanine) complex in the presence of water shown by the decrease in the symmetric stretching frequency of the phosphate group of the lipid

Phenylalanine interaction with lipid monolayers at different pHs

Autor: María de los Ángeles Frías, Edgardo Anibal Disalvo, Patricia del Valle Maturana, Andrea Carmen Cutró, Axel Hollmann, Jimena del Pilar Cejas

Publikováno v: Colloids and Surfaces B: Biointerfaces. 135:504-509

The influence of Phe on the surface pressure of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) monolayers at the air?water interface was studied at different initial surface pressures (26 and 40 mN/m) and two pHs (5.0 and 7.3) at constant tempera

Effect of Phloretin on the Binding of 1-Anilino-8-naphtalene sulfonate (ANS) to 1,2-Dimyristoyl-sn-glycero-3-phosphocoline (DMPC) Vesicles in the Gel and Liquid-Crystalline State

Autor: Guillermo G. Montich, Oscar A. Roveri, Andrea Carmen Cutró

Publikováno v: The Journal of Membrane Biology. 248:137-144

Phloretin is a known modifier of the internal dipole potential of lipid membranes. We studied the interaction of phloretin with model lipid membranes and how it influences the membrane dipole organization using ANS as fluorescent probe. The fluoresce

Polyphenols are well known as antioxidant agents and by their effects on the hydration layers of lipid interphases. Among them, gallic acid and its derivatives are able to decrease the dipole potential and to act in water as a strong antioxidant. In
