Various constituents isolated from plants with described or suggested antihypertensive, spasmolytic or diuretic activity were tested in an in in vitro-guinea pig papillary muscle model for possible calcium-channel blocking activity. Among the isolated compounds some phenylpropanoids of essential oil (e.g. apiol), mono- and sesquiterpene derivatives (e.g. bisabolol-oxide A), naphthoquinones (e.g. juglone, 7-methyljuglone, plumbagin, garlic constituents), some phenolics and alkaloids showed good to moderate activity (IC(50):15-100 μM). Some of the tested compounds caused a prolonged duration of the contraction, suggesting an additional K(+)-channel blocking effect.
从具有描述或暗示的抗高血压、松弛平滑肌或利尿活性的植物中分离出的各种成分,在体外豚鼠乳头状肌模型中进行了可能的钙通道阻断活性测试。在所分离的化合物中,一些精油中的苯丙素(例如,莪术醇)、单萜和倍半萜衍生物(例如,金合欢醇-氧化物 A)、萘醌(例如,胡桃醌、7-甲基胡桃醌、紫铆因、大蒜成分)、一些酚类和生物碱表现出良好至中等的活性(IC(50):15-100 μM)。一些测试的化合物导致收缩持续时间延长,提示存在额外的 K(+)通道阻断作用。
