title: [Effects of various radicinin analogs on pulse amplitude and arterial blood pressure].
abstract: The action of some radicinin analogues on the pulse amplitude in urethane anesthetized rats has been studied. The compounds used are:2,7-dimethyl-4H,5H-pyrano[4,3-b]pyran-4,5-dione (I); 2,3-dihydro-2,7-dimethyl-4H,5H-pyrano[4,3-b]pyran-4,5-dione (II) 7,8-dihydro-2,7-dimethyl-4H,5H-pyrano[4,3-b]pyran-4,5-dione (III) 2,3,7,8-tetrahydro-2,7-dimethyl-4H,5H-pyrano[4,3-b]pyran-4,5-dione(IV); 2,3,7,8,4',8'-hexahydro-2,7-dimethyl-4H,5H-pyrano[4, 3-b]pyran-4,5-dione (V); 3-crotonyl-4-hydroxy-6-methyl-2H-pyran-2-one (VI); 3-hexanoyl-4-hydroxy-6-methyl-2H-pyran-2-one (VII); 3-hexanoyl-5,6-dihydro-4-hydroxy-6-methyl-2H-pyran-2-one (VIII). A clear increase in the pulse has been seen with the compounds (II), (V) and (VII) especially at the lowest doses, while a decrease in the pulse is caused by the compounds (I) and (VIII). The studied substances have no effects on systolic blood pressure in normotensive unanesthetized rats.
