Herein we describe the potential of different alkene isosteres to mimic intramolecular hydrogen bonds and stabilize ?-helices in diverse peptide sequences.

Synthesis of hydrogen-bond surrogate α-helices as inhibitors of protein-protein interactions.

Project description:The α-helix is a prevalent secondary structure in proteins and is critical in mediating protein-protein interactions (PPIs). Peptide mimetics that adopt stable helices have become powerful tools for the modulation of PPIs in vitro and in vivo. Hydrogen-bond surrogate (HBS) α-helices utilize a covalent bond in place of an N-terminal i to i+4 hydrogen bond and have been used to target and disrupt PPIs that become dysregulated in disease states. These compounds have improved conformational stability and cellular uptake as compared to their linear peptide counterparts. The protocol presented here describes current methodology for the synthesis of HBS α-helical mimetics. The solid-phase synthesis of HBS helices involves solid-phase peptide synthesis with three key steps involving incorporation of N-allyl functionality within the backbone of the peptide, coupling of a secondary amine, and a ring-closing metathesis step.

Design, synthesis and protein-targeting properties of thioether-linked hydrogen bond surrogate helices.

Project description:Appropriately-placed hydrogen bond surrogates have been demonstrated to efficiently nucleate helical conformations. Herein we describe an efficient method for the synthesis of thioether-based hydrogen bond surrogate (teHBS) helices. A teHBS helix is shown to adopt a stable conformation and target its cognate protein receptor with high affinity.

Dynamical binding of hydrogen-bond surrogate derived Bak helices to antiapoptotic protein Bcl-xL.

Project description:A new peptide modification strategy was recently developed to replace the i to i + 4 hydrogen bond of the main chain of an alpha-helix with a carbon-carbon covalent bond to afford highly stable constrained alpha-helices, termed hydrogen-bond surrogate (HBS) helices. HBS helices that mimic the Bak BH3 domains were experimentally demonstrated to target protein Bcl-x(L) with high affinity. In this study, molecular dynamics (MD) simulation is used to understand how the covalent modification of the natural Bak sequence affects the binding to Bcl-x(L) at molecular levels. The binding mechanism of HBS helix to Bcl-x(L) and the effect of synthesized cyclic structures are analyzed by MD and MM-PBSA calculations for comparison with the native binding of Bak-Bcl-x(L). The present MD result shows that the entropy of the HBS structure is considerably reduced, and the presence of the N-terminal HBS macrocycle impacts residues at the C-terminus of the helix, but the conformation of the corresponding binding structures is not significantly changed. Our analysis shows that substitution of an aspartic acid residue--a helix breaker--with a hydrophobic residue not only enhances the helicity of the peptide but also stabilizes the structure of the binding complex. The present computational result is consistent with the experimental observation and provides explanations for the altered binding properties of the artificial Bak alpha-helix. Our study underscores the importance of the dynamical effect in protein-peptide interaction in which entropic effect plays a major role.

Evaluation of biologically relevant short alpha-helices stabilized by a main-chain hydrogen-bond surrogate.

Project description:We previously reported the design and synthesis of a new class of artificial alpha-helices in which an N-terminal main-chain hydrogen bond is replaced by a carbon-carbon bond derived from a ring-closing metathesis reaction [Chapman, R. N.; Dimartino, G.; Arora, P. S. J. Am. Chem. Soc. 2004, 126, 12252-12253]. Our initial study utilized an alanine-rich sequence; in the present manuscript we evaluate the potential of this method for the synthesis of very short (10 residues) alpha-helices representing two different biologically relevant alpha-helical domains. We extensively characterized these two sets of artificial helices by NMR and circular dichroism spectroscopies and find that the hydrogen-bond surrogate approach can afford well-defined short alpha-helical structures from sequences that do not spontaneously form alpha-helical conformations.

Hydrogen Bond Surrogate Stabilization of β-Hairpins.

Project description:Peptide secondary and tertiary structure motifs frequently serve as inspiration for the development of protein-protein interaction (PPI) inhibitors. While a wide variety of strategies have been used to stabilize or imitate α-helices, similar strategies for β-sheet stabilization are more limited. Synthetic scaffolds that stabilize reverse turns and cross-strand interactions have provided important insights into β-sheet stability and folding. However, these templates occupy regions of the β-sheet that might impact the β-sheet's ability to bind at a PPI interface. Here, we present the hydrogen bond surrogate (HBS) approach for stabilization of β-hairpin peptides. The HBS linkage replaces a cross-strand hydrogen bond with a covalent linkage, conferring significant conformational and proteolytic resistance. Importantly, this approach introduces the stabilizing linkage in the buried β-sheet interior, retains all side chains for further functionalization, and allows efficient solid-phase macrocyclization. We anticipate that HBS stabilization of PPI β-sheets will enhance the development of β-sheet PPI inhibitors and expand the repertoire of druggable PPIs.

Optimized synthesis of hydrogen-bond surrogate helices: surprising effects of microwave heating on the activity of Grubbs catalysts.

Project description:This manuscript discusses microwave-assisted solid-phase synthesis of hydrogen-bond surrogate based alpha-helices and analogues by ring-closing metathesis (RCM). Microwave-mediated RCM allows access to a greater variety of amino acid residues in the macrocycles in shorter reaction times and higher yields compared to conventional heating. Surprisingly, we discovered that the Grubbs II catalyst is highly active under the influence of microwaves but catalytically dead under oil-bath conditions for the metathesis of these peptide bisolefins.

Backbone Hydrogen Bond Strengths Can Vary Widely in Transmembrane Helices.

Project description:Although backbone hydrogen bonds in transmembrane (TM) helices have the potential to be very strong due to the low dielectric and low water environment of the membrane, their strength has never been assessed experimentally. Moreover, variations in hydrogen bond strength might be necessary to facilitate the TM helix breaking and bending that is often needed to satisfy functional imperatives. Here we employed equilibrium hydrogen/deuterium fractionation factors to measure backbone hydrogen bond strengths in the TM helix of the amyloid precursor protein (APP). We find an enormous range of hydrogen bond free energies, with some weaker than water-water hydrogen bonds and some over 6 kcal/mol stronger than water-water hydrogen bonds. We find that weak hydrogen bonds are at or near preferred γ-secretase cleavage sites, suggesting that the sequence of APP and possibly other cleaved TM helices may be designed, in part, to make their backbones accessible for cleavage. The finding that hydrogen bond strengths in a TM helix can vary widely has implications for membrane protein function, dynamics, evolution, and design.
