Abstract
Amino-γ-lactam (Agl) bridged dipeptides, commonly known as Freidinger lactams, have been shown to constrain peptide backbone topology and stabilize type II' β-turns. The utility of these links as peptide constraints has inspired new approaches to their incorporation into complex peptides and peptoids, all of which require harsh reaction conditions or protecting groups that limit their use on unprotected peptides and proteins. Herein, we employ a mild and selective alkylation of selenomethionine in acidic aqueous solution, followed by immobilization of the alkylated peptide on to bulk reverse-phase C18 silica and base-induced lactamization in DMSO. The utilization of selenomethionine, which is readily introduced by synthesis or expression, and the mild conditions enable selective backbone engineering in complex peptide and protein systems.

Abstract
Non-cationic and amphipathic indoloazepinone-constrained (Aia) oligomers have been synthesized as new vectors for intracellular delivery. The conformational preferences of the [l-Aia-Xxx]n oligomers were investigated by circular dichroism (CD) and NMR spectroscopy. Whereas Boc-[l-Aia-Gly]2,4 -OBn oligomers 12 and 13 and Boc-[l-Aia-β3 -h-l-Ala]2,4 -OBn oligomers 16 and 17 were totally or partially disordered, Boc-[l-Aia-l-Ala]2 -OBn (14) induced a typical turn stabilized by C5 - and C7 -membered H-bond pseudo-cycles and aromatic interactions. Boc-[l-Aia-l-Ala]4 -OBn (15) exhibited a unique structure with remarkable T-shaped π-stacking interactions involving the indole rings of the four l-Aia residues forming a dense hydrophobic cluster. All of the proposed FITC-6-Ahx-[l-Aia-Xxx]4 -NH2 oligomers 19-23, with the exception of FITC-6-Ahx-[l-Aia-Gly]4 -NH2 (18), were internalized by MDA-MB-231 cells with higher efficiency than the positive references penetratin and Arg8 . In parallel, the compounds of this series were successfully explored in an in vitro blood-brain barrier (BBB) permeation assay. Although no passive diffusion permeability was observed for any of the tested Ac-[l-Aia-Xxx]4 -NH2 oligomers in the PAMPA model, Ac-[l-Aia-l-Arg]4 -NH2 (26) showed significant permeation in the in vitro cell-based human model of the BBB, suggesting an active mechanism of cell penetration.

Abstract
We present here an efficient alternative to N-methylation for the purpose of morphing protein-binding peptides into more serum-stable and cell-permeable compounds. This involves the incorporation of a cycloalanine (CyAla) into a peptide in a way that avoids difficult coupling steps. We demonstrate the utility of this chemistry in creating a cell-permeable derivative of a high-affinity HIV Rev protein-binding peptide.
