Three new neurotropic sesquiterpenoids, veranisatins A, B and C, were isolated from star anise (Illicium verum HOOK. fil., Illiciaceae). Veranisatins showed convulsion and lethal toxicity in mice at a dose of 3 mg/kg (p.o.), and at lower doses they caused hypothermia. Veranisatin A and the related compound, anisatin, were tested for the other pharmacological activities such as locomotor activity and analgesic effect. Both compounds decreased the locomotion enhanced by methamphetamine at oral doses of 0.1 and 0.03 mg/kg, respectively, and demonstrated the analgesia on acetic acid-induced writhing and tail pressure pain at almost similar doses.
从八角茴香(Illicium verum HOOK. fil.,Illiciaceae)中分离出三种新的神经活性倍半萜化合物,veranisatins A、B和C。veranisatins在小鼠体内以3 mg/kg(口服)的剂量表现出癫痫发作和致死毒性,而在较低剂量下则引起体温过低。对veranisatin A及其相关化合物anisatin进行了其他药理活性测试,如运动活性和镇痛效果。这两种化合物分别在0.1和0.03 mg/kg的口服剂量下减少甲基苯丙胺增强的运动活动,并在几乎相同的剂量下显示出对乙酸诱导的扭体和尾部压迫疼痛的镇痛作用。
