Cardiovascular activity of aromatic guanidine compounds.

A series of aromatic guanidines and several 1-phenylbiguanides was prepared and tested for cardiovascular (CV) effects in anesthetized dogs measuring heart rate, blood pressure, carotid artery blood flow, and myocardial force changes. The predominant CV effect at minimally effective dose was vasoconstriction unassociated with cardiac stimulation. The structure-activity relationships of the compounds were discussed comparing their structural similarities to the beta-phenylethylamines. The most potent members of the series were phenylguanidines substituted in the 3 and 4 positions on the aromatic nucleus with hydroxy or chloro groups. Preliminary mechanism studies indicated that the 3,4-dihydroxyphenylguanidines act at least partially by a direct alpha-adrenergic mechanism
