Background

Ki: 49 ±14 nM for neuromedin B-induced endpoint in huNMBR cells

Neuromedin B, a mammalian peptide of the bombesinlike peptide family sharing amino acid homology with its amphibian counterpart ranatensin, elicits a diverse array of biological responses in central and peripheral tissues. BIM 23042 [D-Nal-Cys-Tyr- D-Trp-Lys-Val-Cys-Nal-NH2] is a selective neuromedin B antagonist.

In vitro: BIM 23042 has a l00-fold greater affinity for BB1 receptors than BB2 receptors. The submaximal mobilisation observed with neuromedin B (1 nM) was abolished by BIM 23042 but restored with a subsequently higher concentration of neuromedin B (1 μM). BIM 23042 competitively inhibited neuromedin B-induced endpoint in huNMBR cells with a Ki of 49 ±14 nM [1].

In vivo: In cat upper GI tract, SSocta, at concentrations of 10 mM, did not influence the smooth muscle tone but shifted NMB concentration response to the right yielding (Ki=1.7±0.8 mM). Ssocta inhibited both NMB- and GRP-induced contractions on the esophagus. the NMB-receptor antagonist SSocta had no effect on circular fundic muscle indicating the absence of this receptor subtype on fundus. [2].

Clinical trial: Up to now, BIM 23042 is still in the preclinical development stage.
