N(1)-STERICALLY HINDERED 2H-IMIDAZOL-2-ONE ANGIOTENSIN-II RECEPTOR ANTAGONISTS - THE CONVERSION OF SURMOUNTABLE ANTAGONISTS TO INSURMOUNTABLE ANTAGONISTS
The surmountable (competitive) N1-(2-methylphenyl)-2H-imidazol-2-one a
ngiotensin II receptor antagonist SC-54628 is converted to an insurmou
ntable (noncompetitive) antagonist SC-54629 by the addition of a methy
l group at the 6-position of the phenyl ring.
