Polymeric Nanotubes as Drug Delivery Vectors-Comparison of Covalently and Supramolecularly Assembled Constructs. Kerr, A., Sagita, E., Mansfield, E. D. H., Nguyen, T., Feeney, O. M., Pouton, C. W., Porter, C. J. H., Sanchis, J., & Perrier, S. BIOMACROMOLECULES, 23(6):2315–2328, June, 2022. doi abstract bibtex Rod-shaped nanoparticles have been identified as promising drug delivery candidates. In this report, the in vitro cell uptake and in vivo pharmacokinetic/bio-distribution behavior of molecular bottle-brush (BB) and cyclic peptide self-assembled nanotubes were studied in the size range of 36-41 nm in length. It was found that BB possessed the longest plasma circulation time (t1\2 \textgreater 35 h), with the cyclic peptide system displaying an intermediate half-life (14.6 h), although still substantially elevated over a non-assembling linear control (2.7 h). The covalently bound BB underwent substantial distribution into the liver, whereas the cyclic peptide nanotube was able to mostly circumvent organ accumulation, highlighting the advantage of the inherent degradability of the cyclic peptide systems through their reversible aggregation of hydrogen bonding core units.
