Abstract
Suppressor of cytokine signaling 1 (SOCS1) has emerged as a potential therapeutic target in inflammatory and viral diseases. SOCS1 operates via its kinase inhibitory region, Src homology 2 (SH2) domain, and SOCS box to negatively regulate the Janus kinase/signal transducers and activators of transcription signaling pathway. In this study, we utilized native phosphotyrosine peptide substrates as a starting point to iteratively explore the requirement of each amino acid position to target the SH2 domain of SOCS1. We show that Met, Thr, Thr, Val, and Asp in the respective -1, +1, +2, +3, and +5 positions within the peptide substrate are favored for binding to the SOCS1-SH2 domain and identifying several phosphotyrosine peptides that have potent SOCS1 binding affinity with IC50 values ranging from 20 to 70 nM and greater than 100-fold selectivity against the closely related SOCS family proteins, CIS, SOCS2, and SOCS3. The optimized phosphotyrosine peptide was shown to stabilize SOCS1 in a thermal shift assay using cell lysates and inhibited SOCS1-mediated ubiquitination of a target substrate in a biochemical assay. Collectively, these data provide the framework to develop cell-permeable peptidomimetics that further investigate the potential of the SOCS1-SH2 domain as a therapeutic target in inflammatory and viral diseases.

Abstract
Access to phosphotyrosine (pTyr) mimetics requires multistep syntheses, and therefore late stage incorporation of these mimetics into peptides is not feasible. Here, we develop and employ metallaphotoredox catalysis using 4-halogenated phenylalanine to afford a variety of protected pTyr mimetics in one step. This methodology was shown to be tolerant of common protecting groups and applicable to the late stage pTyr mimetic modification of protected and unprotected peptides, and peptides of biological relevance.

Abstract
Protein tyrosine phosphatases (PTPs) are important therapeutic targets for medicinal chemists and biochemists. General strategies for the development of inhibitors of these enzymes are needed. Several modular strategies which rely on phosphotyrosine mimics are known for PTP inhibitors. Previous strategies include phosphonomethylphenylalanine (Pmp) derivatives which act as competitive inhibitors. Pmp amino acid derivatives have been used to develop specific inhibitors by incorporation into sequences recognized by the PTP of interest. We report the synthesis of a new phosphonotyrosine analog, l-phosphonobromomethylphenylalanine (BrPmp), which acts as an inhibitor of PTPs. The BrPmp derivative was prepared as an Fmoc-protected amino acid which can be used in standard solid phase peptide synthesis (SPPS) methods. The synthesis of the protected amino acid derivative requires 11 steps from tyrosine with a 30% overall yield. Enzyme inhibition studies with the PTP CD45 demonstrate that BrPmp derivatives are irreversible inhibitors of the enzyme. A tripeptide which incorporated BrPmp had increased inhibitory potency against PTP relative to BrPmp alone, confirming that the incorporation of BrPmp into peptide sequences provides additional context to improve enzyme binding.

Abstract
Phosphonomethyl phenylalanine (Pmp), a nonhydrolyzable mimic of phosphotyrosine, is an important building block in the development of peptide-based PTP inhibitors. We have designed a novel, efficient synthesis of N-Bz-Pmp(t-Bu)2-OH. A Pmp-containing peptide based on a known biological substrate of the tyrosine phosphatase CD45 (Ac-TEGQ-Pmp-QPQP-NH2) inhibits CD45 with an IC50 value of approximately 100 microM with virtually no inhibition of TCPTP up to concentrations of 120 microM.

Abstract
Copper (I) promoted [3+2] Huisgen cycloaddition of azides with terminal alkynes was used to prepare triazole-containing macrocycles based on the Grb2 SH2 domain-binding motif, 'Pmp-Ac(6)c-Asn', where Pmp and Ac(6)c stand for 4-phosphonomethylphenylalanine and 1-aminocyclohexanecarboxylic acid, respectively. When cycloaddition reactions were conducted at 1mM substrate concentrations, cyclization of monomeric units occurred. At 2mM substrate concentrations the predominant products were macrocyclic dimers. In Grb2 SH2 domain-binding assays the monomeric (S)-Pmp-containing macrocycle exhibited a K(d) value of 0.23microM, while the corresponding dimeric macrocycle was found to have greater than 50-fold higher affinity. The open-chain dimer was also found to have affinity equal to the dimeric macrocycle. This work represents the first application of 'click chemistry' to the synthesis of SH2 domain-binding inhibitors and indicates its potential utility.

Abstract
Aberrant signaling through protein-tyrosine kinase (PTK)-dependent pathways is associated with several proliferative diseases. Accordingly, PTK inhibitors are being developed as new approaches for the treatment of certain cancers. Growth factor receptor bound protein 2 (Grb2) is an important downstream mediator of PTK signaling that serves obligatory roles in many pathogenic processes. One of the primary functions of Grb2 is to bind to specific phosphotyrosyl (pTyr)-containing sequences through its Src homology 2 (SH2) domain. Agents that bind to the Grb2 SH2 domain and prevent its normal function could disrupt associated PTK signaling and serve as alternatives to kinase-directed inhibitors. Starting from the X-ray crystal structure of a lead peptide bound to the Grb2 SH2 domain, this review will summarize important contributions to these efforts. The presentation will be thematically arranged according to the region of peptide modified, proceeding from the N-terminus to the C-terminus, with a special section devoted to aspects of conformational constraint.

Methodology is described here for the efficient parallel synthesis and cyclization of linear peptide libraries using intramolecular S-alkylation chemistry in combination with Multipin solid phase peptide synthesis (Multipin SPPS). The effective use of this methodology was demonstrated with the synthesis of a 72-member combinatorial library of cyclic thioether peptide derivatives of the conserved four-residue structural motif DD/EXK found in the active sites of the five crystallographically defined orthodox type II restriction endonucleases, EcoRV, EcoRI, PvuII, BamHI and BglI.

Abstract
The Src homology 2 (SH2) domain is the most prevalent protein binding module that recognizes phosphotyrosine. This approximately 100-amino-acid domain is highly conserved structurally despite being found in a wide variety proteins. Depending on the nature of neighboring protein module(s), such as catalytic domains and other protein binding domains, SH2-containing proteins play many different roles in cellular protein tyrosine kinase (PTK) signaling pathways. Accumulating evidence indicates SH2 domains are highly versatile and exhibit considerable flexibility in how they bind to their ligands. To illustrate this functional versatility, we present three specific examples: the SAP, Cbl and SOCS families of SH2-containing proteins, which play key roles in immune responses, termination of PTK signaling, and cytokine responses. In addition, we highlight current progress in the development of SH2 domain inhibitors designed to antagonize or modulate PTK signaling in human disease. Inhibitors of the Grb2 and Src SH2 domains have been extensively studied, with the aim of targeting the Ras pathway and osteoclastic bone resorption, respectively. Despite formidable difficulties in drug design due to the lability and poor cell permeability of negatively charged phosphorylated SH2 ligands, a variety of structure-based strategies have been used to reduce the size, charge and peptide character of such ligands, leading to the development of high-affinity lead compounds with potent cellular activities. These studies have also led to new insights into molecular recognition by the SH2 domain.

Abstract
The growth factor receptor-bound protein 2 (Grb2) is an SH2 domain-containing docking module that participates in the signaling of numerous oncogenic growth factor receptor protein-tyrosine kinases (PTKs). Presented herein is a 5-methylindolyl-containing macrocyclic tetrapeptide mimetic (5) that binds to Grb2 SH2 domain protein with K(d)=75 pM. This represents the highest affinity yet reported for a synthetic inhibitor against any SH2 domain. In whole cell assays this novel analogue is able to effectively block the association of Grb2 to cognate cytoplasmic erbB-2 at IC(50)<10nM without prodrug derivatization or the addition of carrier peptide motifs. Anti-mitogenic effects against erbB-2-dependent breast cancers are achieved at non-cytotoxic concentrations (IC(50)=0.6 microM). Macrocycle 5 may be representative of a new class of therapeutically relevant Grb2 SH2 domain-directed agents.
