Abstract
Urotensin II receptor (UT) modulators that differentiate the effects of the endogenous cyclic peptide ligands urotensin II (UII) and urotensin II-related peptide (URP) offer potential for dissecting their respective biological roles in disease etiology. Selective modulators of hUII and URP activities were obtained using 1,3,4-benzotriazepin-2-one mimics of a purported bioactive γ-turn conformation about the Bip-Lys-Tyr tripeptide sequence of urocontrin ([Bip4]URP). Considering an active β-turn conformer about the shared Phe-Trp-Lys-Tyr sequence of UII and URP, 8-substituted 1,3,4-benzotriazepin-2-ones were designed to mimic the Phe-Bip-Lys-Tyr tetrapeptide sequence of urocontrin, synthesized, and examined for biological activity. Subtle 5- and 8-position modifications resulted in biased signaling and selective modulation of hUII- or URP-induced vasoconstriction. For example, p-hydroxyphenethyl analogs 17b-d were strong Gα13 and βarr1 activators devoid of Gαq-mediated signaling. Tertiary amides 15d and 17d negatively modulated hUII-induced vasoconstriction without affecting URP-mediated responses. Benzotriazepinone carboxamides proved to be exceptional tools for elucidating the pharmacological complexity of UT.

Abstract
Topological mimicry of peptide β-turn secondary structures has been investigated using a 1,3,5,8-tetrasubstituted 1,3,4-benzotriazepin-2-one scaffold. Approaches were conceived for the synthesis of tetrasubstituted benzotriazepinones from 4-acetyl-3-aminobenzoate based on aza-amino acid chemistry and different orthogonal protection strategies. Installation of an 8-position carboxylate on the aromatic ring enabled a diverse array of substituents to be introduced for mimicry of the i-position residue. Benzotriazepin-2-one crystallization and X-ray analysis demonstrated that in spite the absence of a stereogenic carbon center, the scaffold could serve as type I and I' β-turn mimics, because pyramidalization of the N3-nitrogen in the benzotriazepin-2-one provides potential for adoptive chirality. 1,3,5,8-Tetrasubstituted 1,3,4-benzotriazepin-2-one scaffolds offer interesting potential for the cost-effective synthesis of nonpeptide β-turn surrogates for peptide mimicry in various recognition events.

Abstract
The urotensinergic system, involved in the development and/or progression of numerous pathological conditions, is composed of one G protein-coupled receptor (UT) and two endogenous ligands known as urotensin II (UII) and urotensin II-related peptide (URP). These two structurally related hormones, which exert common and divergent effects, are thought to play specific biological roles. In recent years, we have characterized an analog termed urocontrin A (UCA), i.e. [Pep4]URP, which is capable of discriminating the effects of UII from URP. Such an action could allow the delineation of the respective functions of these two endogenous ligands. In an effort to define the molecular determinants involved in this behavior and to improve the pharmacological profile of UCA, we introduced modifications from urantide, considered for some time as a lead compound for the development of UT antagonists, into UCA and assessed the binding, contractile activity and G protein signaling of these newly developed compounds. Our results show that UCA and its derivatives exert probe-dependent effects on UT antagonism, and we have further identified [Pen2, Pep4]URP as a Gq biased ligand with an insurmountable antagonism in our aortic ring contraction assay.

Abstract
Peptides are a growing therapeutic class due to their unique spatial characteristics that can target traditionally "undruggable" protein-protein interactions and surfaces. Despite their advantages, peptides must overcome several key shortcomings to be considered as drug leads, including their high conformational flexibility and susceptibility to proteolytic cleavage. As a general approach for overcoming these challenges, macrocyclization of a linear peptide can usually improve these characteristics. Their synthetic accessibility makes peptide macrocycles very attractive, though traditional synthetic methods for macrocyclization can be challenging for peptides, especially for head-to-tail cyclization. This review provides an updated summary of the available macrocyclization chemistries, such as traditional lactam formation, azide-alkyne cycloadditions, ring-closing metathesis as well as unconventional cyclization reactions, and it is structured according to the obtained functional groups. Keeping peptide chemistry and screening in mind, the focus is given to reactions applicable in solution, on solid supports, and compatible with contemporary screening methods.

Abstract
Over the last decade, the urotensinergic system, composed of one G protein-coupled receptor and two endogenous ligands, has garnered significant attention as a promising new target for the treatment of various cardiovascular diseases. Indeed, this system is associated with various biomarkers of cardiovascular dysfunctions and is involved in changes in cardiac contractility, fibrosis and hypertrophy contributing, like the angiotensinergic system, to the pathogenesis and progression of heart failure. Significant investment has been made toward the development of clinically relevant UT ligands for therapeutic intervention, but with little or no success to date. This system therefore remains to be therapeutically exploited. Pepducins and other lipidated peptides have been used as both mechanistic probes and potential therapeutics; therefore, pepducins derived from the human urotensin II receptor might represent unique tools to generate signaling bias and study hUT signaling networks. Two hUT-derived pepducins, derived from the second and the third intracellular loop of the receptor (hUT-Pep2 and [Trp1, Leu2]hUT-Pep3, respectively) were synthesized and pharmacologically characterized. Our results demonstrated that hUT-Pep2 and [Trp1, Leu2]hUT-Pep3 acted as biased ago-allosteric modulators, triggered ERK1/2 phosphorylation and to a lesser extent, IP1 production and stimulated cell proliferation yet were devoid of contractile activity. Interestingly, both hUT-derived pepducins were able to modulate human urotensin II (hUII)- and urotensin II-related peptide (URP)-mediated contraction albeit to different extents. These new derivatives represent unique tools to reveal the intricacies of hUT signaling and also a novel avenue for the design of allosteric ligands selectively targeting hUT signaling potentially.

Abstract
In the past few years, we have identified two allosteric modulators of the urotensinergic system with probe-dependent action, termed Urocontrin (UC) and Urocontrin A (UCA). Such action is atypical and important since it will allow us to understand the specific function of the functionally selective cognate ligands of this system, namely urotensin II and urotensin II-related peptide. Delineating the molecular determinants involved in this particular behavior would represent an important step toward designing small molecules suitable for pharmacologic and/or therapeutic intervention. Hence, we undertook an exploratory research by replacing the Trp4 residue of URP with several para-substituted phenylalanine amino acids in order to get a grasp on the required nature, distance, and orientation of the side chain of this residue for allosteric modulatory action. We found that the position of the second aromatic group is crucial, and we identified two new allosteric modulators: [Trip4]URP and [Phe(pPy-4)4]URP with probe-dependent action.

Abstract
γ,δ-Unsaturated ketones, so-called homoallylic ketones, have served as versatile building blocks for the synthesis of a variety of heterocycles, carbocycles, natural products, and reactive intermediates. Procured by a variety of processes, including conjugate addition of vinyl organometallic reagents to unsaturated ketones, allylation of silyl enol ethers, and rearrangements, homoallylic ketones are often synthesized by step-intensive methods. The cascade addition of 2 equiv of vinyl Grignard reagent to a carboxylate was reported by the Lubell laboratory in 2003 to give effective access to homoallylic ketones from a variety of aromatic, aliphatic, and α-amino methyl esters. Employing readily accessible vinyl magnesium halides in the presence of a catalytic amount of copper salt, this cascade reaction provides high yields of homoallylic ketones with minimal side product by a process featuring the assembly and collapse of a tetrahedral intermediate with expulsion of alkoxide ion, followed by conjugate addition to the resulting enone. Application of the cascade reaction to the synthesis of various homoallylic ketones has provided versatile building blocks for the synthesis of targets for different applications. For example, by employing (hetero)aryl di- and tricarboxylates as precursors, copper-catalyzed cascade additions have provided donor-acceptor and star-shaped monomers for optical-electronic materials. Amino ester starting materials have given homoallylic ketones for the synthesis of various peptidomimetics, including heteroarylalanines, hydroxyethylene isoesters, and diazepinone turn mimics. Moreover, anthranilate has served as building block to prepare various pyrrole, quinoline, benzodiazepine, and benzotriazepine heterocyles. In addition, cascade additions on hydroxyprolinates have given access to bipyrrole precursors of the prodigiosin family of natural products. In the interest to highlight the utility of the copper-catalyzed cascade addition of vinyl Grignard reagents to carboxylates, this Account provides details on the broad scope of substrates that deliver homoallylic ketone products as well as an overview of the wide range of applications in which this method may impact including materials and peptide science, heterocycle and natural product synthesis, and medicinal chemistry.
