Antibodies to the C-terminus of the cholecystokinin precursor: radioimmunoassay and immunohistochemical studies in adult and developing rat gut.

abstract：:Large species differences have been previously observed in the pharmacology of bradykinin (BK) B2 receptor antagonists. We investigated the effect of two novel non-peptide antagonists, compound 9 (a benzodiazepine peptidomimetic related to icatibant) and the thiosemicarbazide bradyzide on the rabbit B2 receptor (contr...
