Abstract
The interactions between chiral molecules and cell membranes have attracted more and more attention in recent decades, due to their importance in molecular science and medical applications. It is observed that some peptides composed of different chiral amino acids may have distinct interactions with a membrane. How does the membrane exhibit a selective behavior related to the chirality of the peptides? Microscopically, the interactions between the peptides and the membrane are poorly understood. In this work, we study the interactions between an amphipathic peptide (C6) and POPC membrane with simulations. The kinetics and thermodynamics of peptide enantiomers during the adsorption to the membrane are characterized with direct simulations and umbrella sampling. It is observed that there are slow kinetics for the peptide composed of D-type amino acids. Along the observed pathways, the free energy landscapes are determined with umbrella sampling techniques. A free-energy barrier for the peptide composed of D-amino acids is observed, which is consistent with the kinetic observations. The results indicate the concurrent adsorption and rotation of the peptide helix. The local interactions between the peptides and the membrane are examined in detail, including the contact interactions between the peptides and the membrane, and the distributions of the lipids around the peptide. There are observable differences of the local interactions for the cases related to different peptide enantiomers. These results further demonstrate the importance of the rotation of peptide helix during the adsorption. More interestingly, all these kinetic differences between peptide enantiomers can be explained based on the conformations of the residue Trp and interactions between Trp and lipid molecules. These results give us a molecular understanding of the mechanism of the chirality-dependent peptide-membrane interactions, and may provide clues to designing systems which are sensitive to the chirality of membranes.

Abstract
The use of chiral surfactants results in a powerful tool to form chiral assemblies of (L)proline-functionalized porphyrin derivatives in EtOH/H[Formula: see text]O exploiting hydrophobic effect. The formation of chiral heteroaggregated species strictly depends both on the configuration of the chiral center of the surfactant and on its concentration, opening the possibility to tune the supramolecular asymmetry of the final structures.

Abstract
Drug delivery to the brain can be achieved by various means, including blood-brain barrier (BBB) disruption, neurosurgical-based approaches, and molecular design. Recently, passive diffusion BBB shuttles have been developed to transport low-molecular-weight drug candidates to the brain which would not be able to cross unaided. The low water solubility of these BBB shuttles has, however, prevented them from becoming a mainstream tool to deliver cargos across membranes. Here, we describe the design, synthesis, physicochemical characterization, and BBB-transport properties of phenylproline tetrapeptides, (PhPro)4, an improved class of BBB shuttles that operates via passive diffusion. These PhPro-based BBB shuttles showed 3 orders of magnitude improvement in water solubility compared to the gold-standard (N-MePhe)4, while retaining very high transport values. Transport capacity was confirmed when two therapeutically relevant cargos, nipecotic acid and l-3,4-dihydroxyphenylalanine (i.e., l-DOPA), were attached to the shuttle. Additionally, we used the unique chiral and conformationally restricted character of the (PhPro)4 shuttle to probe its chiral interactions with the lipid bilayer of the BBB. We studied the transport properties of 16 (PhPro)4 stereoisomers using the parallel artificial membrane permeability assay and looked at differences in secondary structure. Most stereoisomers displayed excellent transport values, yet this study also revealed pairs of enantiomers with high enantiomeric discrimination and different secondary structure, where one enantiomer maintained its high transport values while the other had significantly lower values, thereby confirming that stereochemistry plays a significant role in passive diffusion. This could open the door to the design of chiral and membrane-specific shuttles with potential applications in cell labeling and oncology.
