Targeting Peptides

CPK peptide is a tumor-localizing peptide. CPK peptide specifically binds to the monocarboxylate transporter 1 (MCT1) receptor, which is overexpressed in many human colon cancer cell lines but not in normal cells. CPK peptide can be used in tumor diagnosis research.

ALPS1 peptide from ArfGAP1 is a curvature selective peptide from ArfGAP1 ALPS1 motif. Curvature selectivity can be used to develop broad-spectrum antiviral peptides.

CXCL9(74-103) is a derivative peptide of CXCL9 that has a high affinity for glycosaminoglycans (GAGs) and can bind to GAGs. CXCL9(74-103) possesses anti-angiogenic properties, capable of reducing EGF, VEGF165, and FGF-2-mediated angiogenesis processes in vitro, without exhibiting cytotoxicity.

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

GB-6 is a short linear peptide that targets the gastrin releasing peptide receptor (GRPR). GRPR is overexpressed in pancreatic cancer. Based on the tumor selectivity and tumor-specific accumulation properties of GB-6, GB-6 labeled with near infrared (NIR) fluorescent dyes or radionuclide netium-99m (99mTc) can be used as a high-contrast imaging probe. GB-6 has excellent in vivo stability, with tumor to pancreatic and intestinal fluorescence signal ratios of 5.2 and 6.3, respectively, in SW199 0 subcutaneous xenograft models. GB-6 can rapidly target tumors and accurately delineate tumor boundaries, which has broad application prospects.

rTAT is a potent cell penetrating peptide.

Gly-Arg-Gly-Asp-Ser-NH2 is a pentapeptide with no N-terminal modification. Gly-Arg-Gly-Asp-Ser-NH2 can be coupled to carrriers.

Cyclic SSTR agonist octreotide is a Octreotide (HY-P0036), serving as the cyclic Somatostatin Receptor SSTR agonist.

293P-1 is a peptide with tissue-specific homing properties. 293P-1 is specific for hepatocytes with sequences of SNNNVRPIHIWP.

Rabies Virus Matrix Protein Fragment (RV-MAT) is a polypeptide. Rabies Virus Matrix Protein Fragment targets the acetylcholine receptor (AChR) that exists on the cell surface.

CooP is a linear glioblastoma-targeting nonapeptide. CooP binds to the mammary-derived growth inhibitor/fatty acid binding protein 3 (FABP3) in the glioblastoma cells and its associated vasculature. CooP is used for the targeted delivery of chemotherapy and different nanoparticles.

REA is a homing peptide that targets pre-cancerous tumor lymphatic vessels. REA homes to lymphatic vessels at the pre-cancerous tumor stage, but does not recognize tumor lymphatic vessels. REA can be used in pre-cancerous tumor research.

LyP-2 is a peptide that homes to tumor lymphatics. LyP2 homes to lymphatics of C8161 melanomas and cervical carcinomas and K14-HPV16 skin, but not to MDA-MB435 tumors, showing heterogeneity in the molecular markers of tumor cells and lymphatics.

AGR is a peptide. AGR recognizes lymphatic vessels in fully developed prostate tumors but not in the pre-malignant lesions.

Thrombospondin-1 (1016-1021) (human, bovine, mouse), a Thrombospondin-1-derived peptide, is a truncated peptide devoid of CD47-binding activity.

Tumor targeted pro-apoptotic peptide (CNGRC-GG-D(KLAKLAK)2) is an anti-tumor peptide. Tumor targeted pro-apoptotic peptide disrupts mitochondrial membranes and promotes apoptosis, showing anticancer activity in mice.

Cyclo(Arg-Gly-Asp-D-Phe-Val) (Cyclo(RGDfV)) is an integrin αvβ3 inhibitor. Cyclo(Arg-Gly-Asp-D-Phe-Val) has antitumor activity. Cyclo(Arg-Gly-Asp-D-Phe-Val) can be used for the research of acute myeloid leukemia.

Octreotide (SMS 201-995) pamoate is a somatostatin receptor agonist and synthetic octapeptide endogenous somatostatin analogue. Octreotide pamoate can bind to the somatostatin receptors which are mainly subtypes 2, 3 and 5. Octreotide pamoate increases Gi activity and reduces intracellular cAMP production. Octreotide pamoate has antitumor activity, mediates apoptosis and may also be used in disease studies in acromegaly.

WLSEAGPVVTVRALRGTGSW TFA is a cardiomyocyte-targeting peptide that specifically recognizes tenascin X on the surface of cardiomyocytes. WLSEAGPVVTVRALRGTGSW TFA can serve as a targeting ligand to conjugate with various therapeutic carriers (drugs, genes, exosomes, nanoparticles, etc.) for research on cardiovascular diseases (such as myocardial infarction, heart failure).

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