title: Lack of significant unspecific effects of HOE 140 and other novel bradykinin antagonists in vitro and in vivo.
abstract: The novel, potent and long-acting bradykinin (BK) antagonists, HOE 140, compound II and compound III, slightly decreased blood pressure, but did not affect heart rate and respiration of rats. The antagonists did not cause bronchoconstriction in guinea-pigs. Neither HOE 140 nor BK released histamine from isolated perfused hindlegs of rats. The lack of significant unspecific side effects of the novel antagonists of effective doses will further increase the usefulness of these compounds for experimental and therapeutic purposes.
