产品描述 Description

ML-18 is a non-peptide bombesin receptor subtype 3 (BB₃) antagonist that inhibits [¹²⁵I]BA1 binding to NCI-H1299 lung cancer cells transfected with human BB₃ receptors (IC₅₀ = 4.8 μM).¹ It is selective for BB₃ over the gastrin releasing peptide receptor (GRPR) and the neuromedin B receptor (NMBR) with IC₅₀ values of 16 and >100 μM, respectively, in a radioligand binding assay. ML-18 (16 μM) reversibly inhibits BA1-induced increases in cytosolic calcium in NCI-H1299 cells. It also inhibits BA1-induced phosphorylation of ERK and EGFR and reduces proliferation of NCI-H1299 cells.

实验参考方法 Experimental Reference Method

Kinase experiment:

The cells are incubated in SIT buffer containing 0.25% bovine serum albumin and 250 μg/mL bacitracin and 125I-BA1 (100,000 cpm) is added, as well as various concentrations of unlabelled competitor (ML-18). After incubation at 37°C for 30 min, free 125I-BA1 is removed by washing 3 times in buffer and the cells which contain bound 125I-BA1 is dissolved in 0.2 N NaOH and counted in a gamma counter. The IC50 is calculated for each unlabeled competitor[1].

Cell experiment:

Cell viability is measured using the MTT assay. NCI-H727 or NCI-H1299 cells transfected with BRS-3 are treated with ML-18 (0, 4.8, 16, 48 μM) or gefitinib added. After 2 days, 15 μL of 0.1 % MTT solution added. After 4 h, 150 μL of DMSO is added. After 16 h, the optical density at 570 nm is determined[1].
