Kinin antagonists: design and activities.

Bradykinin antagonists effective in a great variety of kinin-responsive tissues have been developed and used to study the roles of kinins in various physiological and pathological phenomena. Structural changes required to yield antagonists and to confer high potency, tissue selectivity, and resistance to enzymatic degradation have been explored in several hundred analogs. Certain of these offer promise for the development of drugs effective against pain, inflammation, and asthma.
