Interaction of hydrophobic and amphipathic antimicrobial peptides with lipid bicelles

Autor: Marco Bortolus, Annalisa Dalzini, Kyung-Soo Hahm, Claudio Toniolo, Anna Lisa Maniero

Publikováno v: Journal of Peptide Science. 20:517-525

Bicelles are model membrane systems that can be macroscopically oriented in a magnetic field at physiological temperature. The macroscopic orientation of bicelles allows to detect, by means of magnetic resonance spectroscopies, small changes in the o

Publikováno v: Biopolymers. 102:40-48

We describe the challenging solid-phase synthesis of the medium-length (14 amino-acid residues) peptaibiotic ampullosporin A, originally extracted from the fungus Sepedonium ampullosporum, and an analog doubly spin labeled (at positions 3 and 13) wit

Scientific Reports

Peptaibols are peculiar peptides produced by fungi as weapons against other microorganisms. Previous studies showed that peptaibols are promising peptide-based drugs because they act against cell membranes rather than a specific target, thus lowering

Insights into Peptide-Membrane Interactions of Newly Synthesized, Nitroxide-Containing Analogs of the Peptaibiotic Trichogin GA IV Using EPR

Autor: Marco, Bortolus, Annalisa, Dalzini, Anna Lisa, Maniero, Giacomo, Panighel, Alvaro, Siano, Claudio, Toniolo, Marta, De Zotti, Fernando, Formaggio

Trichogin GA IV is a short-length (10-amino acid long), mostly hydrophobic, peptaibiotic with an N-terminal fatty acyl chain and a C-terminal 1,2-amino alcohol. A cardinal role of the terminal moieties in the cytotoxic activity of trichogin has been

An EPR study of ampullosporin A, a medium-length peptaibiotic, in bicelles and vesicles

Autor: Marina Gobbo, Fernando Formaggio, Claudio Toniolo, Anna Lisa Maniero, Marco Bortolus, Annalisa Dalzini

Publikováno v: Physical chemistry chemical physics : PCCP. 18(2)

Ampullosporin A is a medium-length (14-amino acid long) hydrophobic peptide of the peptaibol family. In this work, electron paramagnetic resonance and circular dichroism spectroscopies were applied to study the interaction of synthetic ampullosporin

Multifrequency EPR study and DFT calculations of a C60 bisadduct anion

Autor: Alfonso Zoleo, Anna Lisa Maniero, Maurizio Prato, Marina Brustolon, Marco Bellinazzi

Publikováno v: Chemical Physics Letters. 412:470-476

The monoanion of bis-TRANS2-[ N -methyl-3,4-fulleropyrrolidine] (TRANS2 − ) was investigated by continuous wave (CW) and pulsed EPR. X-band spectra showed signals due to 14 N and 13 C hyperfine couplings (hcc). DFT calculations of 14 N and 13 C iso

Publikováno v: Synthetic Metals. 147:127-131

The photoexcited triplet states of different π-conjugated organic dyes, included in segregating matrices of organic hosts with channel-like cavities, have been studied by time resolved-EPR. The dyes have been studied also in glassy phases and the tr
