Calcium Antagonistic Properties of the Sesquiterpene T‐Cadinol and Related Substances : Structure‐Activity Studies
The calcium antagonistic properties of (+)‐T‐cadinol, some of its stereoisomers and related terpenes were investigated in both functional and radioligand binding studies, and the effects were compared with those of the dihydropyridine calcium antagonist (±)‐nimodipine. In the isolated rat aorta, the terpenes relaxed contractions induced by 60 mM K+ more potently than those induced by phenylephrine
