Structure-activity relationship of mastoparan analogs: effects of the number and positioning of Lys residues on secondary structure, interaction with membrane-mimetic systems and biological activity
(Elsevier B. V., 2015-05-02)
In this study, a series of mastoparan analogs were engineered based on the strategies of Ala and Lys scanning in relation to the sequences of classical mastoparans. Ten analog mastoparans, presenting from zero to six Lys ...
Combining SERRS and electrochemistry to characterize sensors based on biomembrane mimetic models formed by phospholipids
(Royal Soc Chemistry, 2011-01-01)
The surface-enhanced resonance Raman scattering (SERRS) technique and an electronic tongue system based on cyclic voltammetry were coupled combining structural information and sensitivity. Layer-by-Layer (LbL) films ...

Effects of insecticide acephate on membrane mimetic systems: The role played by electrostatic interactions with lipid polar headgroups
(2021-06-15)
Pesticides are important agrochemicals to yield high crop productivity but their indiscriminate use may harm the environment and human health. In order to seek a compromise between effectiveness as insecticide and safety ...
Síntese e estrutura do peptídeo antimicrobiano Pantinina-3 e de seus análogos
(Universidade Estadual Paulista (Unesp), 2018-03-09)
O peptídeo antimicrobiano Pantinina-3 (P3) possui 13 resíduos e é derivado do veneno do escorpião africano Pandinus imperator. Ele apresenta alta atividade antimicrobiana contra bactérias Gram-positivas, principalmente ...
Incorporation of antigenic GPI-proteins from Leishmania amazonensis to membrane mimetic systems: Influence of DPPC/cholesterol ratio
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
The reconstitution of membrane proteins into liposomes is a useful tool to prepare antigenic components that induce immunity. We have investigated the influence of the dipalmitoylphosphatidylcholine (DPPC)/cholesterol molar ...
Multi-drug delivery system based on lipid membrane mimetic coated nano-hydroxyapatite formulations
(Elsevier Science, 2018-09-05)
Local delivery systems from an osteoconductive biomaterial are suggested as a promising strategy to avoid simultaneously peri-implant traumas and to induce tissue regeneration. In this work, it is detailed the design and ...
