bombesin

Bombesin is a 14-amino acid peptide originally isolated from the skin of the European fire-bellied toad (Bombina bombina). It has two known homologs in mammals called neuromedin B and gastrin-releasing peptide.

[Lys3]-Bombesin is a biologically active peptide used in PET (Positron Emission Tomography) imaging to identify GRPR (gastrin-releasing peptide receptor) positive prostate cancer. The compound, when conjugated with a corresponding monoclonal antibody, can selectively trigger CD64-dependent monocyte and neutrophil-mediated lysis in small cell carcinoma.

Bombesin acetate is a 14-amino acid peptide originally isolated from the skin of the European fire-bellied toad (Bombina bombina). It has two known homologs in mammals called neuromedin B and gastrin-releasing peptide.

Bombesin receptor antagonist that inhibits bombesin binding to rat brain with an IC50 value of 2 μM. Inhibits amylase release in vitro (IC50 = 4 μM) and attenuates bombesin-mediated suppression of food intake in vivo.

Bombesin receptor antagonist

[D-Phe12]-Bombesin acetate inhibits bombesin-stimulated secretion.

Spantide antagonizes both bombesin & substance P. It is also tachykinin receptor antagonist.

Ranatensin, a undecapeptide isolated from skin of Rana pipiens, is a naturally occurring bombesin-like peptide.

Ranatensin acetate, a undecapeptide isolated from skin of Rana pipiens, is a naturally occurring bombesin-like peptide.

Litorin acetate, an amphibian bombesin peptide derivative, is an bombesin receptor agonist. It stimulates the contraction of smooth muscle, stimulates gastrin, gastric acid, and pancreatic secretion, and suppresses the nutriment in vivo.

Neuromedin C (porcine) is a bombesin-like neuropeptide obtained from the porcine spinal cord. Neuromedin C (porcine) has contractile activity in the rat uterus. Neuromedin C (porcine) has the potential to study neurological-related diseases.

Brain-derived acidic fibroblast growth factor (102-111) is a peptide fragment of brain-derived acidic fibroblast growth factor (aFGF). aFGF is an angiogenic vascular endothelial cell mitogen produced in bovine brain that has sequence homology to interleukin-1. It also shares sequence homology with the known neuropeptides neuromedin C , bombesin , neuromedin K , substance K , substance P , physalaemin, and eledoisin. aFGF (102-111) corresponds to amino acid residues 102-111 of the fulllength peptide.

BIM-26226, a gastrin-releasing peptide, serves as a potent and selective antagonist to the bombesin receptor, effectively inhibiting BN- or GRP-stimulated amylase release with IC50 values in the nanomolar range. It is utilized in cancer research [1] [2].

BA 1 TFA acts as a potent agonist for the bombesin (BB) family of receptors, exhibiting high affinity binding to Bombesin receptor subtype-3 (BRS3), gastrin-releasing peptide receptor (GRPR), and neuromedin B receptor (NMBR), with IC50 values of 6, 0.4, and 2.5 nM, respectively [1].

GRP (14-27) (human, porcine, canine) serves as a ligand for bombesin receptors, with specific binding inhibited by GTP and GDP, but unaffected by GMP [1].

(D-Arg1,D-Pro2,D-Trp7,9,L-Leu11)-Substance P (acetate), an antagonist of Substance P and Bombesin, modulates ocular inflammatory responses triggered by antidromic trigeminal nerve stimulation [1].

Neuromedin B (NMB) is one of the bombesin (BN)-related peptides in mammals. It was originally purified from pig spinal cords, and it has been shown to be present in central nervous system as well as in gastrointestinal tract.

RC-3095 TFA (RC-3095 (TFA)) is a bombesin gastrin-releasing peptide (BN GRP) antagonist with potential anticancer activity.
