Abstract
An efficient functionalization of tyrosine residues in phenolic regions is achieved under metal-free conditions. The strategy involves the conversion of a tyrosine residue to 4-amino phenylalanine or 4-amino-3-methoxy phenylalanine in short peptides through a controlled oxidative dearomatization. This transformation is achieved in one pot with good yields and excellent regioselectivity. Consequently, the self-assembly of the peptide compounds has been studied at the nanoscopic level before and after functionalization. The results suggest that the peptide derivatives comprising amide groups promote intermolecular H-bonding interactions and the difference in -OH and -NH2 functional groups is found to be responsible for the morphological changes. Morphological transitions from 1D nanowires to 2D nanosheets were observed during functional group modification.

Abstract
Peptide and protein selective modification at tyrosine residues has become an exploding field of research as tyrosine constitutes a robust alternative to lysine and cysteine-targeted traditional peptide/protein modification protocols. This review offers a comprehensive summary of the latest advances in tyrosine-selective cleavage, functionalization, and conjugation of peptides and proteins from the past three years. This updated overview complements the extensive body of work on site-selective modification of peptides and proteins, which holds significant relevance across various disciplines, including chemical, biological, medical, and material sciences.

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.
