活性研究
- 1. 抗腎絲球基底膜(anti-glomerular basement membrane, anti-GBM)腎炎,主要是由自身抗體對腎絲球基底膜的抗原產生不正常的結合作用而發生的疾病,而白血球在此種腎炎中扮演主要角色之一。實驗中口服給予患有anti-GBM的大鼠30 mg/kg acetoside,每天一次,連續15天,顯著的降低尿蛋白(urinary protein)。因腎炎聚集在腎絲球的白血球(包含CD4+, ED-1, CD8+, IL2 receptor+, Ia+細胞),在給予15天後,累積在腎絲球的數量都有明顯的下降[4]。血漿中的膽固醇(cholesterol)及肌肝酸(creatinine)亦有顯著的下降[5]。
- 2. 草石蠶中所含的aceteoside, stachysoside C, phenylethanoid glycoside,給予經氰化鉀(KCN)引起缺氧的小鼠,顯著的降低死亡小鼠的數目[3]。
毒性研究
- 症狀
- 未知
- 有毒成分[17-20]
- 1. Caffeic acid
- 2. Verbascoside
- 中毒劑量[6, 7]
- 未知
- 機轉
- 未知
- 基因毒性
- 以人類淋巴細胞為模型,給予verbascoside,濃度為0.01, 0.05, 0.1 mM,測量染色體畸變(chromosome aberrations, CA)及姐妹染色體交換(sister chromosome exchange, SCE)。結果顯示染色體畸變頻率(aberration frequency)及畸變細胞在0.01 mM以上均有顯著提高。姐妹染色體交換的數量也同樣在0.01 mM以上就顯著的升高。另外,在給藥48小時後,蛋白質PPAR-1及p53量也呈現濃度相關的顯著上升。以HPLC測量給藥後的細胞液發現,verbascoside水解為caffeic acid,而caffeic acid可能就是導致這些活性的物質[7]。
- 2. 果針對草石蠶活性成分verbascoside及caffeic acid進行果蠅翅斑試驗(Drosophila wing spot test),研究結果指出verbascoside (27-173 mM)對並不會產生任何形態的翅斑,但caffeic acid (27-135 mM)確造成翅斑產生頻率顯著下降,而最高濃度(173 mM)則顯著上升。而在高活性(含cytochrome P450酵素)組別中,caffeic acid顯著的提高翅斑的產生頻率,顯示須經代謝後草石蠶活性成分才會較具基因毒性[6]。
