RSC Chemical Biology Blog

RSC Chemical Biology and RSC Pharmaceutics are extending the submission deadline for the upcoming themed collection on ‘Endocytosis and Cellular Delivery‘.

The new deadline for submissions is 30 April 2025

Articles can be submitted to either of the two journals depending on the topic of the manuscript and how well it fits in to the journal’s scope. Authors who contribute their work to RSC Pharmaceutics will benefit from a full waiver of the article processing charges, so their work can be published and read at no cost.

Guest Edited by Prof. Alexander Kros (Leiden University), Prof. Vince Rotello (University of Massachusetts) and Prof. Georgina Such (University of Melbourne), this collection will explore how both biological and synthetic tools can be leveraged to understand the impact of material structure on the migration of specific cellular barriers, aiming to enhance the delivery efficiency of macromolecules and delivery systems such as liposomes, lipid nanoparticles, and polymeric carriers. Key topics will include the following:

1. Novel tools to understand and quantify cellular trafficking of nanoparticles and their cargo, including processes such as endosomal escape, membrane fusion, cytosolic delivery and nuclear localisation.
2. Fundamental understanding of how nanoparticle structure impacts cellular interactions.
3. Design of new delivery systems that incorporate intelligent strategies to migrate biological barriers for more effective therapeutic delivery.
4. Novel tools, methodologies to understand and quantify cell uptake and the fate of the multiple components in drug delivery systems.
5. Tools/basic understanding on the role of the protein corona on the fate of the particles beyond the very general basic level.

Articles can be submitted via the respective journal’s website, rsc.li/rsc-chembio or rsc.li/RSCPharma. Information on the journals’ scopes can be found at the bottom of this message. We would be grateful if, upon submission you would mention that your manuscript is intended for this themed collection.  Please note that all submissions are subject to the journal’s normal peer review processes, an initial assessment to confirm the manuscript’s suitability for full peer review.

Promotion of the collection is scheduled for  mid-2025, with articles published online as soon as they’re accepted.

We are thrilled to announce the launch of the prestigious Outstanding Early Career Research Award, aimed at recognising and celebrating outstanding contributions to RSC Chemical Biology. This initiative seeks to honour the dedication, innovation, and impactful research of promising early career researchers.

Benjamí Oller Salvia and his team are such remarkable individuals. In their paper, BrainBike peptidomimetic enables efficient transport of proteins across brain endothelium,  Prof Oller Salvia introduced BrainBikes, a novel family of bicyclic protease-resistant peptide shuttles designed to overcome the challenge of delivering protein therapeutics to the brain.

Protein therapeutics face a challenge in reaching the brain due to their low permeability across the blood-brain barrier (BBB). Despite previous attempts with brain shuttle peptides to enhance BBB transport of some therapeutics, effectively transporting protein cargoes remains difficult. In this study, the researchers introduce BrainBikes, a new family of bicyclic protease-resistant peptide shuttles capable of increasing transport of proteins, including antibody derivatives.

Using a trifunctional chemical linker, several bicyclic analogues are generated from a linear peptide targeting the transferrin receptor (TfR1). These analogues show increased metabolic resistance, with one variant, BrainBike-4 (BB4), demonstrating a high affinity for cells with high levels of TfR1. Initially, the researchers demonstrated that BB4 can enhance the transport of a model fluorescent protein by fourfold. Subsequently, BB4 is site-specifically conjugated to a single chain variable antibody fragment (scFv) using a chemoenzymatic approach. Conjugation of BB4 leads to a fivefold increase in the transport of the scFv in a human cell-based model of the BBB.

These results highlight the potential of bicyclic peptidomimetics as brain shuttles and present new opportunities for the transport of biotherapeutics across the BBB.
