Journal ArticleDOI
Lactam-Stapled Cell-Penetrating Peptides: Cell Uptake and Membrane Binding Properties.
Marco J. Klein,Samuel Schmidt,Parvesh Wadhwani,Jochen Bürck,Johannes Reichert,Sergii Afonin,Marina Berditsch,Tim Schober,Roland Brock,Manfred Kansy,Anne S. Ulrich +10 more
TL;DR: The data suggest that cell uptake of amphipathic CPPs correlates with their adopted α-helix content in membranes rather than their helicity in solution, and that lactam stapling was found to vary strongly with regard to the different aspects of peptide-membrane interactions.
Journal ArticleDOI
Structure–Activity Relationships of Photoswitchable Diarylethene-Based β-Hairpin Peptides as Membranolytic Antimicrobial and Anticancer Agents
Oleg Babii,Sergii Afonin,Aleksandr Yu. Ishchenko,Aleksandr Yu. Ishchenko,Tim Schober,Anatoliy O. Negelia,Ganna Tolstanova,Liudmyla V. Garmanchuk,Liudmyla Ostapchenko,Igor V. Komarov,Igor V. Komarov,Anne S. Ulrich +11 more
TL;DR: A dissociation of the anticancer activity from hemolysis was found and high PTIs were demonstrated across a range of different cancer cell lines, including a doxorubicin-resistant one.
Journal ArticleDOI
Stereochemical effects on the aggregation and biological properties of the fibril-forming peptide [KIGAKI]3 in membranes
Parvesh Wadhwani,Johannes Reichert,Erik Strandberg,Jochen Bürck,Julia Misiewicz,Sergii Afonin,Nico Heidenreich,Susanne Fanghänel,Pavel K. Mykhailiuk,Pavel K. Mykhailiuk,Igor V. Komarov,Anne S. Ulrich +11 more
TL;DR: Functional assays showed that the aggregation propensity of KIGAKI does not play a role in its antimicrobial action, but an increased tendency to aggregate promotes other undesirable effects such as hemolysis and membrane fusion.
Journal ArticleDOI
Therapeutic Potential of Gramicidin S in the Treatment of Root Canal Infections
TL;DR: The successful treatment of persistently infected root canals of two volunteers confirms the high effectiveness of the cyclic antimicrobial peptide gramicidin S, and suggests its applications for approval in root canal medication.
Journal ArticleDOI
Action of the multifunctional peptide BP100 on native biomembranes examined by solid-state NMR
Julia Misiewicz,Sergii Afonin,Stephan L. Grage,Jonas van den Berg,Erik Strandberg,Parvesh Wadhwani,Anne S. Ulrich +6 more
TL;DR: The structure and dynamics of the short multifunctional peptide BP100 are explored using a multinuclear solid-state NMR approach and similarity suggests that BP100 has the same surface-bound helical structure and high mobility in the different biomembranes and model membranes alike, independent of charge, thickness or cholesterol content of the system.
