Abstract

Prophylactic administration of LL 21-945 [4-(3-tert. butyl-amino-2-pivaloyloxypropoxy)-9-fluorenone] during 15 weeks to Grollman rats depressed the development of hypertension, tachycardia and myocardial pathogical changes. The tachycardia was eliminated and the degree of the myocardial pathological changes and coronary sclerosis was less severe than in the untreated Grollman rats. The survival rate was slightly improved with LL 21-945. With respect to the biochemical parameters studied, only a tendency of LL 21-945 to moderate the rises in blood cholesterol, total glycerides and urea was observed towards the end of the experiment.
