Bombesin Receptor

Receptor

The bombesin (Bn) receptor family includes the gastrin-releasing peptide (GRPR) and neuromedin B (NMBR) receptors, Bn receptor subtype 3 (BRS-3) and Bn receptor subtype 4 (BB4). Activation of these receptors mediates a wide spectrum of biological activities including important changes in the central nervous system including satiety, control of circadian rhythm, thermoregulation, and in peripheral tissues including stimulation of gastrointestinal hormone release, activation of macrophages, and effects on development. Bn-related peptides also have potent growth effects causing proliferation of bothnormal cells and various tumor cell lines.

BRS-3 is receiving increased attention, because not only is it important in a number of gastrointestinal (GI) tract and central nervous system (CNS) processes, but also because it is one of the G-protein coupling receptor families most frequently ectopically or overexpressed by a different tumors, including prostate cancer, small cell lung cancer, breast cancer, CNS tumors, and carcinoids (intestinal, thymic, and bronchial).

    GB-6
    Chemical
    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.
