Abstract: The invention provides bradykinin antagonist compounds wherein many (or all) of the peptide bonds of bradykinin are eliminated to yield compounds which specifically compete with bradykinin for binding to the bradykinin receptor. More particularly, the invention relates to compounds having, in appropriate spatial arrangement, two positively charged moieties flanking a hydrophobic organic moiety and a moiety which mimics a beta turn conformation.

Abstract: The present invention is directed to certain novel compounds identified as bridged piperidines of the general structural formula: ##STR1## wherein R.sup.1, R.sup.1a, R.sup.2a, R.sup.3, R.sup.3a,R.sup.4, R.sup.5, A, X, and Y are as defined herein. These compounds promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to treat physiological or medical conditions characterized by a deficiency in growth hormone secretion, such as short stature in growth hormone deficient children, and to treat medical conditions which are improved by the anabolic effects of growth hormone. Growth hormone releasing compositions containing such compounds as the active ingredient thereof are also disclosed.

Abstract: Provided by the present invention are novel methods of detecting ligand interactions, as well as regents useful in the method, including DNA and host cells; and more specifically relates to novel methods for the detection of protein/protein interactions and their application in epitope mapping and the study of ligand/receptor interactions. Also provided are vaccines and kits comprising the expression products and host cells of the invention.

Abstract: Novel compounds with as few as three natural amino acids that incorporate a substituted 4-keto-1,3,8-triazaspiro[4.5]decan-3-alkanoyl bridge in place of selected fragments of peptidic bradykinin receptor antagonists are pseudopeptides with potent bradykinin receptor antagonist actions. These pseudopeptides and their pharmaceutical compositions are of benefit in treating conditions and diseases of mammals, including humans, in which an excess of bradykinin or a related kinin is produced endogenously or is received exogenously, for example via insect bite.
