Bondiskey, Douglas J. Pettibone, Roger M. Freidinger, Mark G. BockAntagonism of the bradykinin B1 receptor was
demonstrated to be a potential treatment for chronic pain and
inflammation. Novel benzodiazepines were designed that
display subnanomolar affinity for the bradykinin B1 receptor
(Ki = 0.59 nM) and high selectivity against the bradykinin B2
receptor (Ki > 10 μM). In vivo efficacy, comparable to morphine, was demonstrated for lead compounds in a rodent
hyperalgesia model.
