Malik, Uru;Chan, Lai Yue;Cai, Minying;Hruby, Victor J.;Kaas, Quentin;Daly, Norelle L.;Craik, David J. research published 《 Development of novel frog-skin peptide scaffolds with selectivity towards melanocortin receptor subtypes》, the research content is summarized as follows. Melanocortin receptors are pharmaceutically important receptors that are involved in complex physiol. functions. They have been associated with various diseases including obesity, erectile dysfunction, acne, and skin cancer. It has been challenging to transform nonselective endogenous agonist and antagonist ligands into selective and potent ligands. In this study, we investigated naturally occurring peptides derived from frog skin secretions for selectivity and activity toward melanocortin receptors. Three peptides (ORB, ORB2K and ranacyclin-T) were found to have selectivity towards the melanocortin receptor 5 (MC5R). ORB and ORB2K had partial binding affinity at nanomolar concentrations, whereas ranacyclin-T had 57% binding efficiency at 1.6μM. Backbone cyclization of ORB and ORB2K altered the binding efficiency to melanocortin receptors. Our results suggest that these frog-skin peptides could be modified for developing melanocortin-specific ligands and potentially future therapeutics.

Mallek, Aaron J.;Pentelute, Bradley L.;Buchwald, Stephen L. research published 《 Selective N-arylation of p-aminophenylalanine in unprotected peptides with organometallic palladium reagents》, the research content is summarized as follows. The selective N-arylation of p-aminophenylalanine in polypeptides with pre-formed palladium oxidative addition complexes is described. The depressed pKa of the aniline NH₂ group enables chemoselective C-N bond formation on peptides containing multiple other aliphatic amino groups at lysines or the N-terminus via Curtin-Hammett control under mild conditions. Using palladium complexes derived from electron-poor aryl halides, p-aminophenylalanine is fully arylated in aqueous buffer in as little as one hour at micromolar concentrations A complementary protocol using the non-nucleophilic, organic base 1,5-diazabicyclo(4.3.0)non-5-ene (DBN), expands the substrate scope to tolerate electron-rich functional groups provides up to 97% conversion. These procedures enable the chemoselective conjugation of functionally diverse small mol. pharmaceuticals to p-aminophenylalanine containing derivatives of cell-penetrating peptides.

Mao, Runyu;Xi, Shiyi;Shah, Sayali;Roy, Michael J.;John, Alan;Lingford, James P.;Gade, Gerd;Scott, Nichollas E.;Goddard-Borger, Ethan D. research published 《 Synthesis of C-mannosylated glycopeptides enabled by Ni-catalyzed photoreductive cross-coupling reactions》, the research content is summarized as follows. The biol. functions of tryptophan C-mannosylation are poorly understood, in part, due to a dearth of methods for preparing pure glycopeptides and glycoproteins with this modification. To address this issue, efficient and scalable methods are required for installing this protein modification. Here, we describe unique Ni-catalyzed cross-coupling conditions that utilize photocatalysis or a Hantzsch ester photoreductant to couple glycosyl halides with (hetero)aryl bromides, thereby enabling the α-C-mannosylation of 2-bromo-tryptophan, peptides thereof, and (hetero)aryl bromides more generally. We also report that 2-(α-D-mannopyranosyl)-L-tryptophan undergoes facile anomerization in the presence of acid: something that must be considered when preparing and handling peptides with this modification. These developments enabled the first automated solid-phase peptide syntheses of C-mannosylated glycopeptides, which we used to map the epitope of an antibody, as well as providing the first verified synthesis of Carmo-HrTH-I, a C-mannosylated insect hormone. To complement this approach, we also performed late-stage tryptophan C-mannosylation on a diverse array of peptides, demonstrating the broad scope and utility of this methodol. for preparing glycopeptides.

McCoy, Michael A.;Spicer, Dominique;Wells, Neil;Hoogewijs, Kurt;Fiedler, Marc;Baud, Matthias G. J. research published 《 Biophysical Survey of Small-Molecule β-Catenin Inhibitors: A Cautionary Tale》, the research content is summarized as follows. The canonical Wingless-related integration site signaling pathway plays a critical role in human physiol., and its dysregulation can lead to an array of diseases. β-Catenin is a multifunctional protein within this pathway and an attractive yet challenging therapeutic target, most notably in oncol. This has stimulated the search for potent small-mol. inhibitors binding directly to the β-catenin surface to inhibit its protein-protein interactions and downstream signaling. Here, we provide an account of the claimed (and some putative) small-mol. ligands of β-catenin from the literature. Through in silico anal., we show that most of these mols. contain promiscuous chem. substructures notorious for interfering with screening assays. Finally, and in line with this anal., we demonstrate using orthogonal biophys. techniques that none of the examined small mols. bind at the surface of β-catenin. While shedding doubts on their reported mode of action, this study also reaffirms β-catenin as a prominent target in drug discovery.

The β₂-adrenergic receptor (β₂AR) is a G-protein-coupled receptor (GPCR) that responds to the hormone adrenaline and is an important drug target in the context of respiratory diseases, including asthma. β₂AR Function can be regulated by post-translational modifications such as phosphorylation and ubiquitination at the C-terminus, but access to the full-length β₂AR with well-defined and homogeneous modification patterns critical for biochem. and biophys. studies remains challenging. Here, we report a practical synthesis of differentially modified, full-length β₂AR based on a combined native chem. ligation (NCL) and sortase ligation strategy. An array of homogeneous samples of full-length β₂ARs with distinct modification patterns, including a full-length β₂AR bearing both monoubiquitination and octaphosphorylation modifications, were successfully prepared for the first time. Using these homogeneously modified full-length β₂AR receptors, we found that different phosphorylation patterns mediate different interactions with β-arrestin1 as reflected in different agonist binding affinities. Our experiments also indicated that ubiquitination can further modulate interactions between β₂AR and β-arrestin1. Access to full-length β₂AR with well-defined and homogeneous modification patterns at the C-terminus opens a door to further in-depth mechanistic studies into the structure and dynamics of β₂AR complexes with downstream transducer proteins, including G proteins, arrestins, and GPCR kinases.

We describe an application of carrier protein-free strategy in constructing a fully synthetic methamphetamine (METH) vaccine that contains three components: Toll-like receptor 2 ligand, Th2 epitope, and METH hapten. The immunol. evaluation in mice revealed high titers of METH-specific antibodies induced by the construct and the activation of humoral immunity that would be beneficial for neutralization and clearance of the METH mol. Behavioral experiments indicated that the synthetic vaccine attenuated the acquisition of METH-induced conditioned place preference and inhibited the initiation and expression of METH-induced locomotor sensitization. These results demonstrate that the lipopeptide-based vaccine has invoked an immune response and showed the potential of preventing the rewarding and psychoactive effects of METH.

Receptor-specific peptides labeled with positron emitters play an important role in the clin. imaging of several malignancies by positron emission tomog. (PET). Radiolabeled heterobivalent bispecific peptidic ligands (HBPLs) can target more than one receptor type and by this – besides exhibiting other advantages – increase tumor imaging sensitivity. In the present study, we show the initial in vivo evaluation of the most potent heterobivalent gastrin-releasing peptide receptor (GRPR)- and vasoactive intestinal peptide receptor subtype 1 (VPAC₁R)-bispecific radiotracer and determined its tumor visualization potential via PET/CT imaging. For this purpose, the most potent described HBPL was synthesized together with its partly scrambled heterobivalent monospecific homologs and its monovalent counterparts. The agents were efficiently labeled with ⁶⁸Ga³⁺ and evaluated in an initial PET/CT tumor imaging study in a human prostate carcinoma (PCa) xenograft rat tumor model established for this purpose. None of the three ⁶⁸Ga-HBPLs enabled a clear tumor visualization and a considerably higher involvement in receptor-mediated uptake was found for the GRPR-binding part of the mol. than for the VPAC₁R-binding one. Of the monovalent radiotracers, only [⁶⁸Ga]Ga-NODA-GA-PESIN could efficiently delineate the tumor, confirming the results. Thus, this work sets the direction for future developments in the field of GRPR- and VPAC₁R-bispecific radioligands, which should be based on other VPAC₁R-specific peptides than PACAP-27.

The growing epidemic of diabetes means that there is a need for therapies that are more efficacious, safe, and convenient. Here, we report the efficient synthesis of a novel disulfide dimer of human insulin tethered at the N-terminus of its B-chain through placement of a cysteine residue. The resulting peptide was shown to bind to both the insulin receptor isoform B and insulin-like growth factor-1 receptor with comparable affinity to native insulin. In in vivo insulin tolerance tests, the dimer was equipotent to Actrapid insulin and possessed a sustained duration of action greater than that of Actrapid and Glargine. While the secondary structure of our dimeric insulin was similar to that of insulin, it was more resistant to proteolysis. More importantly, our analog was produced in quant. yield from a monomeric thiol insulin scaffold. Our results suggest that this dimer has significant potential to address the clin. needs in the treatment of diabetes.

Preptin is a 34-amino-acid-long peptide derived from the E-domain of a precursor of insulin-like growth factor 2 (pro-IGF2) with bone-anabolic and insulin secretion amplifying properties. Here, we describe the synthesis, structures, and biol. activities of six shortened analogs of human preptin. Eight- and nine-amino-acid-long peptide amides corresponding to the C-terminal part of human preptin were stabilized by two types of staples to induce a higher proportion of helicity in their secondary structure. We monitored the secondary structure of the stapled peptides using CD. The biol. effect of the structural changes was determined afterwards by the ability of peptides to stimulate the release of intracellular calcium ions. We confirmed the previous observation that the stabilization of the disordered conformation of human preptin has a deleterious effect on biol. potency. However, surprisingly, one of our preptin analogs, a nonapeptide stabilized by olefin metathesis between positions 3 and 7 of the amino acid chain, had a similar ability to stimulate calcium ions’ release to the full-length human preptin. Our findings could open up new ways to design new preptin analogs, which may have potential as drugs for the treatment of diabetes and osteoporosis.

The therapeutic potential of antigen-specific regulatory T cells (Treg) has been extensively explored, leading to the development of several tolerogenic vaccines. Dexamethasone-antigen conjugates represent a prominent class of tolerogenic vaccines that enable coordinated delivery of antigen and dexamethasone to target immune cells. The importance of nonspecific albumin association towards the biodistribution of antigen-adjuvant conjugates has gained increasing attention, by which hydrophobic and electrostatic interactions govern the association capacity. Using an ensemble of computational and exptl. techniques, we evaluate the impact of charged residues adjacent to the drug conjugation site in dexamethasone-antigen conjugates (Dex-K/E4-OVA323, K: lysine, E: glutamate) towards their albumin association capacity and induction of antigen-specific Treg. We find that Dex-K4-OVA323 possesses a higher albumin association capacity than Dex-E4-OVA323, leading to enhanced liver distribution and antigen-presenting cell uptake. Furthermore, using an OVA323-specific adoptive-transfer mouse model, we show that Dex-K4-OVA323 selectively upregulated OVA323-specific Treg cells, whereas Dex-E4-OVA323 exerted no significant effect on Treg cells. Our findings serve as a guide to optimize the functionality of dexamethasone-antigen conjugate amid switching vaccine epitope sequences. Moreover, our study demonstrates that moderating the residues adjacent to the conjugation sites can serve as an engineering approach for future peptide-drug conjugate development.
