PBP10, a cell-permeable and selective gelsolin-derived peptide, inhibits formyl peptide receptor 2 (FPR2) over FPR1 [1]. This 10-amino acid (AA) peptide features a rhodamine conjugation at its N terminus, exhibiting bactericidal activity against both gram-positive and gram-negative bacteria while mitigating microbial-induced inflammatory effects [2].

Bid BH3 (80-99) is a biologically active peptide and a pro-apoptotic member of the 'BH3-only' (BOPS) subset within the BCL-2 protein family, crucial in apoptosis regulation. It interacts with Bcl-2, Bax, and Bak to initiate their activation or inactivation, inducing cell death. Bid translocates from the cytosol to the mitochondrial membrane as part of its mechanism. Pyroglutamyl (pGlu) peptides, which can arise from Glutamine (Q) or Glutamic acid (E) at the N-terminus, have a hydrophobic γ-lactam ring that enhances stability and provides resistance to gastrointestinal proteases. These peptides are recognized variants in peptide analyses, including HPLC purity assessments.

FAM-labeled Bid BH3 (80-99) is a biologically active peptide featuring a 5-FAM label at its N-terminus.

Epsilon-V1-2, a Cys-conjugated, is a biologically active peptide known as the εPKC-specific inhibitor. It hampers εPKC functionality by obstructing its translocation and the phosphorylation of MARCKS, additionally perturbing εPKC's interaction with its anchoring protein, εRACK. The peptide includes a cysteine residue at its C-terminus, facilitating the formation of potential disulfide bonds with carrier proteins. Pyroglutamyl formation can occur spontaneously at the N-terminus if glutamine or glutamic acid is present, enhancing peptide stability against gastrointestinal proteases. Pyroglutamyl peptides, a recognized subset, are accounted for in the peptide's purity during HPLC analysis.

γ-Bag cell peptide, a peptide situated near the N-terminus of the egg-laying prohormone, is released from vesicles upon insulin stimulation. It is utilized in research pertaining to both the central and peripheral nervous systems [1].

Sotiburafusp alfa is a humanized bispecific fusion protein comprising a VEGFR-1 extracellular domain fragment (129-228, 1-100 in the current sequence) connected through a 101 GGSGGSGGSGGSGGS 115 peptide linker to the N-terminus (116-564) of a humanized IgG1-kappa anti-human PD-L1 heavy chain with L352>A and L353>A mutations. Additionally, sotiburafusp alfa functions as an angiogenesis inhibitor [1].

[Leu27]-Melan-A, MART-1 (26-35), is a biologically active peptide modified by substituting leucine for alanine at position 27, which enhances its HLA-A*0201 binding, immunogenicity, and antigenicity compared to the natural peptide. Pyroglutamyl (pGlu) peptides, arising from the spontaneous cyclization of glutamine (Q) or glutamic acid (E) at the N-terminus, are a recognized subset of peptides that may confer increased stability due to the hydrophobic γ-lactam ring of pGlu. These pGlu peptides are typically included during peptide purity assessments in HPLC analysis.

Influenza NP (311-325) is a biologically active peptide consisting of amino acids 311 to 325 from the influenza virus nucleoprotein (NP). As a bona fide MHC class II-restricted epitope, it is critical for studying host immune responses during viral infection, inducing robust gamma interferon (IFN-gamma) production in intracellular cytokine assays without stimulating CD8 T-cells in mice. The presence of Glutamine (Q) or Glutamic acid (E) at the N-terminus can lead to spontaneous formation of Pyroglutamyl (pGlu) peptides, enhancing peptide stability against gastrointestinal proteases. These peptides are considered a normal variant and included in peptide purity measurements in HPLC analysis.

EE epitope, a biologically active peptide, is a fragment (314 to 319 amino acids) of the middle T antigen from mouse polyomavirus and is frequently utilized as an epitope tag. Pyroglutamyl (pGlu) peptides, which can arise spontaneously at the N-terminus from either Glutamine (Q) or Glutamic acid (E), are recognized for potentially enhancing peptide stability through the hydrophobic γ-lactam ring of pGlu, particularly against gastrointestinal proteases. Such peptides, as a normal variant, are accounted for within peptide purity assessments during HPLC analysis.

A11, a cell-penetrating peptide, integrates the HIV-1 Tat protein transduction domain with an 11-amino acid segment from the annexin A1 N-terminus (residues 20-30). This compound disrupts the interaction between annexin A1 and the Eph receptor tyrosine kinase A2 (EphA2), leading to enhanced EphA2 ubiquitination in HK1 nasopharyngeal carcinoma (NPC) cells. At a concentration of 10 µM, A11 curtails proliferation, migration, and invasion of HK1 and 5-8F NPC cells. Furthermore, A11 demonstrably diminishes tumor volume in mouse xenograft models of 5-8F and HK1 NPC in vivo.
