bombesin receptor

[D-Phe12,Leu14]-Bombesin acetate inhibits bombesin-stimulated secretion.

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

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.

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].

GB-6, a short linear peptide that selectively binds to the gastrin releasing peptide receptor (GRPR), shows potential as a high-contrast imaging probe due to its tumor selectivity and specific accumulation. Overexpression of GRPR in pancreatic cancer enables GB-6, when labeled with near-infrared (NIR) fluorescent dyes or the radionuclide technetium-99m (99mTc), to serve as an effective agent for tumor visualization. Demonstrating excellent in vivo stability, GB-6 yields tumor to pancreatic and intestinal fluorescence signal ratios of 5.2 and 6.3, respectively, in SW1990 subcutaneous xenograft models. Its rapid tumor targeting capability and precise tumor boundary delineation signify GB-6's extensive potential for clinical applications [1].

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

BA 1 acetate is a potent bombesin receptor agonist (IC50 values are 0.26, 1.55 and 2.52 nM for BB1, BB2 and BB3 respectively). Enhances glucose transport in obese and diabetic primary myocytes. Also stimulates NCI-H1299 lung cancer cell proliferation in v

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].

Potent bombesin receptor agonist (IC50 values are 0.26, 1.55 and 2.52 nM for BB1, BB2 and BB3 respectively). Enhances glucose transport in obese and diabetic primary myocytes. Also stimulates NCI-H1299 lung cancer cell proliferation in vitro.

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.

Broad spectrum neuropeptide inverse agonist and antagonist. Potent full inverse agonist for the ghrelin receptor (EC50 = 5.2 nM); diminishes constitutive ghrelin receptor signaling. Also antagonist at tachykinin, bradykinin, CCK and bombesin receptors. In

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

(D-Phe6,Leu-NHEt13,des-Met14)-Bombesin (6-14), a bombesin (BBN) antagonist, holds potential for cancer research applications [1].

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.

RC-3095, a selective GRPR antagonist, has been shown to have anti-inflammatory properties in different models of inflammation.

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

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

[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.

[D-Arg1,D-Phe5,D-Trp7,9,Leu11]-Substance P acetate ([D-Arg1,D-Phe5,D-Trp7,9,Leu11]-Substance P acetate (96736-12-8 free base)) is a broad spectrum neuropeptide inverse agonist and antagonist. Potent full inverse agonist for the ghrelin receptor (EC50 = 5.2 nM); diminishes constitutive ghrelin receptor signaling. Also antagonist at tachykinin, bradykinin, CCK and bombesin receptors. Induces apoptosis and inhibits cancer cell growth in vitro.

Mammalian bombesin-like peptide neurotransmitter that is an agonist for the gastrin-releasing peptide receptor (GRPR). GRP has been reported to activate GABAergic interneurons in the amygdala leading to increased GABA release and fear suppression in mice

RC-3095 acetate is an antagonist of bombesin gastrin-releasing peptide receptor (GRPR). It exerts protective effects by reducing gastric oxidative injury in the arthritic mice.
