GRPR antagonist-1 

GRPR antagonist-1 是一种有效的胃泌素释放肽受体 (GRPR) 拮抗剂,对某些癌细胞具有细胞毒性 (在PC3、Pan02、HGC-27 细胞中的 IC50 分别是 4.97、4.36、3.40 μM)。GRPR antagonist-1 通过降低 Bcl-2 水平、增加 Bax 水平,来抑制 HGC-27 细胞活力,引起细胞凋亡。具有抗癌活性。

生物活性

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].

IC50 & Target

IC50: 4.97 μM (GRPR) in PC3, 4.36 μM (GRPR) in Pan02, 3.40 μM (GRPR) in HGC-27[1]

体外研究
(In Vitro)

GRPR antagonist-1 (compound 5a) (0.032-100 μM; 48 hours) has the cytotoxicity against certain cancer cells, also reduces PC3, Pan02, HGC-27, and HepG2 cell viability combined with HDAC inhibitor (1 μM)[1].
GRPR antagonist-1 (1, 2, 8 μM; 24 hours) increases the rate of late apoptosis/necrosis, inducing apoptosis of HGC-27 cells[1].
GRPR antagonist-1 (0.8, 4 μM; 24 hours) inhibits HGC-27 cell viability by decreasing the Bcl-2 level and increasing the Bax level, causing apoptosis[1].
