制备方法与用途

生物活性

Convallatoxin 是从 Adonis amurensis Regel et Radde 中分离得到的强心苷。它通过激活 PPARγ 和抑制 NF-κB 有效改善结肠炎。研究发现,Convallatoxin 是一种 P-糖蛋白 (P-gp) 底物,并且 Val982 赖氨酸残基对它的转运至关重要。此外,它还是配体诱导的 MOR 胞吞作用的高效增强剂。Convallatoxin 具有显著的抗炎和抗增殖特性。

体外研究

Convallatoxin 可诱导 HaCaT 细胞发生坏死性凋亡(necroptosis)。

体内研究

Convallatoxin 在两种小鼠银屑病模型中表现出显著的抗皮炎作用。

化学性质

Convallatoxin 是一种白色结晶粉末,熔点为235-242℃。它能溶解于醇和丙酮,微溶于水和氯仿,几乎不溶于醚或石油醚。

用途

Convallatoxin 是一种强心药,与洋地黄制剂类似,主要用于治疗急性及慢性心力衰竭。

生产方法

铃兰(君影草)全草地上部分的粗粉用苯-乙醇混合溶剂提取。随后将提取液浓缩,并用氯仿-乙醇溶液进行进一步抽提和浓缩。再从浓缩液中用水进行抽提,得到水溶液并浓缩后冷却结晶出粗品铃兰毒甙。最后使用甲醇重结晶,即可获得成品。以铃兰全草粗粉计,总收率约为0.01%。
