Koumine 是从钩吻 (Gelsemium elegans) 中得到的生物碱，具有高效抗肿瘤活性，在肿瘤细胞中能够增加 Bax/Bcl-2 的蛋白比例和 caspase-3 的表达。Koumine 具有抗焦虑、抗应激、抗银屑病活性，也可用于缓解疼痛的研究。在类风湿性关节炎动物模型中，Koumine 能够预防关节炎的发展。 Koumine can induce apoptosis of LoVo cells in a time-dependent manner and inhibit the DNA synthesis in LoVo cells, thereby blocking the cell cycle from G1 to S phase. Koumine has a significant analgesic effect in rodent behavioral models of inflammatory and neuropathic pain, and that the reduction in neuropathic pain may be associated with the upregulation of allopregnanolone in the spinal cord. Koumine has therapeutic effect against psoriasis, which is related to the inhibition of epidermal cell proliferation, promoting the formation of granular cells and decreasing the serum level of IL- Koumine can significantly reduce the damage to axon and myelin sheath of the sciatic nerve and increase sensory nerve conduction velocity , without affecting body weight and blood glucose, these findings encourage the use of koumine in the treatment of diabetic neuropathy. Koumine has antineoplastic effect, may be a future breast cancer chemotherapeutic agent. Koumine may produce anxiolytic-effect by increasing the levels of pregnenolone and allopregnenolone in hippocampus.
