Embodiment Construction

[0014] The plant extract in the present invention is swainsonine, which is a plant extract of the genus Oxytropis leguminosae. Swainsonine can be used in combination with the immunomodulator poly IC (poly IC) interleukin (IL-2) or in combination.

[0015] (1) Antitumor activity of swainsonine

[0016] 1. The effect of swainsonine on the survival time of tumor-carrying animals

[0017] An important question in the treatment of cancer with swainsonine is whether the inhibition of tumor metastasis can prolong the survival time of the host. Trials have been performed with swainsonine in combination with the immunomodulators poly-IC (poly IC) or interleukin (IL-2). When swainsonine is used continuously alone, in injection B 16 -BL 16 There was no apparent difference between animals with melanoma cells and untreated animals. However, when swainsonin was combined with poly IC or IL-2, the survival time was significantly different. For example, at 65 days after tumor cell inject...

Abstract

The present invention relates to one kind of plant extractive for treating cancer, and the plant extractive can suppress tumor cell and raise body's immunity obviously. The plant extractive of the present invention is swainsonine extracted from thinleaf crazyweed as one kind of leguminous plant. Swainsonine is used through cooperating with poly IC or IL-2.
