GRPR antagonist-1

GRPR antagonist-1 is a potent gastrin releasing peptide receptor (GRPR) antagonist, having the cytotoxicity against certain cancer cells (IC50 of 4.97, 4.36 and 3.40 μM in PC3, Pan02 and HGC-27 cells, respectively). GRPR antagonist-1 inhibits HGC-27 cell viability by decreasing the Bcl-2 level and increasing the Bax level, causing apoptosis. Anticancer activity[1].
