The ability of reduced peptide bond analogues of gastrin releasing peptide (GRP) to antagonize small cell lung cancer (SCLC) GRP receptors was investigated. BW462U89, BW1023U90, BW2123U89 and BW2258U89 inhibited binding of (125I-Tyr4) BN to NCI-H345 cells with IC50 values of

The binding of (125I-Tyr4)bombesin to rat brain slices was investigated. Radiolabeled (Tyr4)bombesin bound with high affinity (Kd = 4 nM) to a single class of sites (Bmax = 130 fmol/mg of protein); the ratio of specific to nonspecific binding was

Peptides, 15(7), 1289-1295 (1994-01-01)
Because several direct effects of bombesin related peptides on pituitary hormone release have been demonstrated, we chose to study the presence of bombesin binding sites in the adult male rat anterior pituitary in aggregate cell culture by autoradiographic localization of
B E Rogers et al.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 38(8), 1221-1229 (1997-08-01)
The gastrin releasing peptide receptor (GRPr) has a high affinity for the 14 amino acid bombesin peptide. For this analysis, [125I]-Tyr4-bombesin was compared with [125I]-mIP-bombesin (a seven amino acid bombesin analog) for in vitro binding and internalization into tumor cells
