Targeting Peptides

LNSMGQD is a cyclic peptide fragment derived from desmoglein 1 (amino acids 81-86), which mimics trans-interactions and acts as part of the tandem peptide binding interface of desmoglein 2. LNSMGQD not only binds to desmoglein 1 and 3, but also effectively inhibits their homophilic trans-interactions, while reducing the probability of homophilic or heterophilic binding between desmoglein 2 and Dsc2, N-cadherin and E-cadherin. LNSMGQD is applicable to the research on disease mechanisms such as Crohn's disease and pemphigus vulgaris.

LARLLT TFA is an EGFR-binding peptide. LARLLT has the potential for research of EGFR overexpressing cancers, such as lung, ovarian and colorectal cancer.

GPLGLAGGWGERDGS is a peptide with MMP enzyme responsiveness and tumor targeting function, which can be used to monitor enzyme-guided nanoparticle assembly in tumors.

Cyclo(RGDyC) is a cyclic pentapeptide with anti-angiogenic abilities. Cyclo(RGDyC) can be combined with liposome delivery systems for research on ocular neovascular diseases and cancer.

Osteocalcin (Osteocalcin (1-49)) (human) is a vitamin K-dependent bone specific protein. Osteocalcin (human) is chemotactic for several of the cell types frequently found at bone remodeling surfaces.

PSMA targeting peptide (PSMA-1) is a PSMA-binding peptide that selectively binds to the PSMA receptor on prostate cancer cells and acts as a peptide-based siRNA delivery system by complexing and releasing siRNA. PSMA targeting peptide can be used in research on prostate cancer.

RP-182 acetate is a synthetic immunomodulatory peptide that exerts anti-tumor effects by targeting the mannose receptor CD206 (K_d = 8 μM) on the surface of tumor-associated macrophages (TAMs). RP-182 acetate induces a conformational switch of the CD206 receptor, which activates NF-κB signaling and phagocytosis in CD206^high TAMs. RP-182 acetate has dual function: activation of canonical NF-κB signaling, triggering TNFα secretion and autocrine activation of the TNF receptor 1 (TNFR1), leading to activation of caspase 8, apoptosis, and cell death. RP-182 acetate is used in pancreatic cancer and melanoma research.

Osteocalcin (Osteocalcin (1-49)) (human) TFA is a vitamin K-dependent bone specific protein. Osteocalcin (human) TFA is chemotactic for several of the cell types frequently found at bone remodeling surfaces.

IL4RPep-1 is an interleukin-4 receptor (IL-4R) binding agent. IL4RPep-1 preferentially binds to cells with high levels of IL-4R expression compared to those with low levels of expression. IL4RPep-1-labeled liposomes containing Doxorubicin (HY-15142A) are internalized by cells more efficiently. IL4RPep-1-labeled liposomes accumulate more effectively within H226 tumors.

Tet1-Cys peptide is a peptide with the sequence HLNILSTLWKYRC. Tet1 (HLNILSTLWKYR) (HY-P10998) can specifically bind to the neuronal ganglioside receptor GT1b, possessing neuronal targeting capabilities. The Tet1-Cys peptide sequence has an added Cys, which can be used for drug conjugation for research on drug delivery.

CGGK acetate is a control peptide of CAQK peptide (HY-P10216).

H-Glu-Pro-Leu-Gln-Leu-Lys-Met-OH (EM7) acetate is a linear mesenchymal stem cell (MSC) specific peptide. H-Glu-Pro-Leu-Gln-Leu-Lys-Met-OH acetate can be used to prepare Gd-DOTA-peptide complexes.

Heart-homing peptide is a heart-targeting peptide with the sequence CRPPR that mediates cardiac endothelial targeting and accumulates in cardiac tissues. Heart-homing peptide mediates the translocation of liposomal and exosomal cargos across cardiac endothelium into interstitial tissues, enhances the accumulation of exosomes in the heart, and inhibits the GP130-STAT3/ERK1/2/AKT pathway. Heart-homing peptide accumulates at sites of ischemia/reperfusion, myocardial infarction and hypertrophy in mice. Heart-homing peptide can be used for the research of cardiovascular diseases.

123B9, a tumor-homing agent, is a potent and selective EphA2 agonist with a K_d value of 4.0 μM. 123B9 selectively targets the EphA2 tyrosine kinase receptor ligand-binding domain. 123B9 does not appreciably inhibit the ligand binding domains of the most closely related EphA3 and EphA4 receptors.

FRα-targeting peptide C7 is a selective peptide ligand for folate receptor α (FRα) that has specific binding to FRα expressing cells and in vivo tumor targeting ability. FRα-targeting peptide C7 can be used in the research of tumor diagnosis and treatment.

Cyclo (ARG-ALA-ASP- (D-Tyr) -LYS) (TFA) (C (Radyk) (TFA)) is a control peptide for c(RGDyK).

Cyclo(RGDyC) TFA is a cyclic pentapeptide with anti-angiogenic abilities. Cyclo(RGDyC) TFA can be combined with liposome delivery systems for research on ocular neovascular diseases and cancer.

Cyclo(Arg-Gly-Asp-D-Tyr-ε-azido-Nle) (Azido-c(RGDyK)) is a polypeptide composed of arginine, glycine, aspartic acid, and tyrosine that can be used for Synthesis of [¹⁸F]FPyKYNE-c(RGDyK).

Aminopeptidase N Ligand (CD13) NGR peptide is a polypeptide targeting CD13 and can be used as a carrier to mediate intracellular transmission. Aminopeptidase N Ligand (CD13) NGR peptide is often used in cancer research.
