    Abstract:
    The report describes the hypotensive and antihypertensive activity of the compound N-(trans-3-hydroxy-1,2,3,4-tetrahydro-2-naphtyl)-N'-(3-oxo-3-phenylpropyl) piperazine dihydrochloride (P11). The work is made on normotensive cats and rats as well as on spontaneous and experimental (metacorticoid) hypertension. The studies were carried out under the conditions of acute and chronic experiment as the arteria pressure was recorded by blood and bloodless method. The compound P11 show a manifested hypotensive activity with favourable duration and therapeutic width. Its antihypertensive activity is revealed in rats with spontaneous and metacorticoid hypertension both after single and chronic applciation of the compound. The influence on the blood pressure weakens after reserpinization of the animals. The compound possesses slight ganglion-blocking action and manifested alpha and beta adreno-blocking activity: diminishes noradrenaline, adrenaline and isoprenaline responses on the arterial pressure and heart activity in anesthetised cats and rats, shifts to the right the cumulative dose-response curve of noradrenaline on vas deferens of a rat, ect. The hypotensive and antihypertensive effect of the compound P11 is discussed on the basis of its alpha and beta adrenoblocking action and its specific sedative effect.
