The hypotensive action of 4-(5,6-dimethyl-2-benzofuranyl) piperidine HCl (CGP 6085 A) in spontaneously hypertensive rats.
CGP 6085 A, [4-(5,6-dimethyl-2-benzofuranyl)piperidine HCl], has been found to be a mild to moderately potent hypotensive agent. One hour following CGP 6085 A administration (10 mg/kg, i.p.), a maximal reduction in blood pressure of approximately 20-30 mm Hg is observed in spontaneously hypertensive rats. The maximal reduction in blood pressure was observed at a dose of 3 mg/kg. CGP 6085 A blocks 5-HT uptake in the brainstem when assessed in vivo by use of the serotonin depletor, H 75/12 (3-hydroxy-4-methyl-alpha-ethyl-phenylethylamine). The maximal inhibitory effect on 5-HT uptake occurred at 10 mg/kg CGP 6085 A. The reduction in blood pressure correlates well with the ability of the drug to inhibit 5-HT uptake as assayed by H 75/12, with a correlation coefficient of 0.71 for SH rats. However, since the drug has not been widely characterized, alternate explanations for the cardiovascular pharmacological properties of CGP 6085 A are also proposed.
