Single-chain bolalipids PC-C24-PC and PC-C32-PC: impact on skin permeation and penetration of caffeine ex vivo, structural organization of the stratum corneum and corneocyte morphology

Namarig Abdelrahman, Jakob Josef Schmolz, Jacqueline Schwarzinger, Simon Drescher et autres

Synthetic symmetric single-chain bolalipids (SSCBs) are of interest as new pharmaceutical excipients and might offer new prospects to modulate dermal drug delivery. In contrast to classic anionic surfactants and conventional amphiphilic phospholipids, they have been found to hinder drug penetration of charged …

Investigation of keratolytic impact of synthetic bolalipids on skin penetration of a model hydrophilic permeant

Namarig Abdelrahman, Simon Drescher, Lea Ann Dailey, Victoria Klang

Synthetic single-chain bolalipids (SSCBs) are novel excipients in drug delivery, with potential as stabilizers or solubilizers. However, their impact on skin barrier function has not been comprehensively studied. Therefore, two SSCBs (PC-C24-PC and PC-C32-PC) were studied in aqueous systems for their impact …

Cancer immune therapy using engineered ‛tail-flipping’ nanoliposomes targeting alternatively activated macrophages

Praneeth Reddy Kuninty, Karin Binnemars‐Postma, Ahmed Jarray, Kunal P. Pednekar et autres

Alternatively-activated, M2-like tumor-associated macrophages (TAM) strongly contribute to tumor growth, invasiveness and metastasis. Technologies to disable the pro-tumorigenic function of these TAMs are of high interest to immunotherapy research. Here we show that by designing engineered nanoliposomes bio-mimicking peroxidated phospholipids that are …

Investigating bolalipids as solubilizing agents for poorly soluble drugs: Effects of alkyl chain length on solubilization and cytotoxicity

Feng Li, Richard D. Harvey, Paola Modicano, Farzad Hamdi et autres

Synthetic single-chain bolalipids with symmetrical headgroups have shown potential in various pharmaceutical applications, such as the stabilization of liposome bilayers. Despite their amphiphilic character, synthetic bolalipids have not yet been investigated for their suitability as solubilizing agents for poorly soluble drug compounds. …

A Diazirine‐Modified Membrane Lipid to Study Peptide/Lipid Interactions – Chances and Challenges

Julia Dörner, Patricia Korn, Kai Gruhle, Daniel Ramsbeck et autres

Although incorporation of photo-activatable lipids into membranes potentially opens up novel avenues for investigating interactions with proteins, the question of whether diazirine-modified lipids are suitable for such studies, remains under debate. Focusing on the potential for studying lipid/peptide interactions by cross-linking mass …
