4-amino-5-oxy-2,6,6-tri methyl-2-cycloheptene compounds represented by the following general formula: ##STR1## (wherein R.sup.1 and R.sup.2 each independently represent a hydrogen atom, an alkyl group which may have a substituent, or a phenyl group which may have a hydroxyl group, lower alkoxy group, amino group, nitro group, carboxyl group, lower alkoxycarbonyl group or halogen atom, or R.sup.1, R.sup.2 and the nitrogen atom together represent a saturated nitrogen heterocyclic group; R.sup.3 represents a hydrogen atom, a lower alkyl group or a lower aliphatic acyl group); and W represents an oxo group, oxime group or oxime ether group; and their pharmacologically acceptable salts and solvates. The 4-amino-5-oxy-2,6,6-trimethyl-2-cycloheptene compounds exhibit an effect against rat peripheral arterial occlusion models, spontaneous hypertensive rats and histamine-induced airway contraction models, and are thus useful as remedy for hypertension, peripheral arterial occlusion and bronchial asthma.
以下是由以下通用式表示的4-氨基-5-氧基-2,6,6-三甲基-2-环庚烯化合物:##STR1##(其中R.sup.1和R.sup.2各自独立地表示氢原子,可具有取代基的烷基或可具有羟基,较低的烷氧基,氨基,硝基,羧基,较低的烷氧羰基,或卤素原子的苯基;或R.sup.1,R.sup.2和氮原子共同表示饱和氮杂环基;R.sup.3表示氢原子,较低的烷基或较低的脂肪族酰基);W表示氧代基,肟基或肟醚基;以及它们的药学上可接受的盐和溶剂合物。4-氨基-5-氧基-2,6,6-三甲基-2-环庚烯化合物对大鼠周围动脉闭塞模型,自发性高血压大鼠和组胺诱导的气道收缩模型具有作用,因此可用作治疗高血压,周围动脉闭塞和支气管哮喘的药物。
