蓖麻,是一种大戟科蓖麻属的油料作物。从它的种子中提取出来的肽类毒素——蓖麻毒素,是一种植物抗癌新秀。近年来,科学家已阐明了它的结构。过去只限于在动物上试验,临床上一直没有很好地开展。但近年来的临床试验结果却非常鼓舞人心。它对细胞有毒性,中毒细胞早期主要表现为蛋白质合成抑制,而后DNA合成减少,最后RNA合成受到抑制。不同蛋白质合成受抑制的速度不同,其中对骨髓瘤蛋白合成抑制最迅速。 Ramie is an oil crop belonging to the genus Urtica. The ricin, a peptide toxin extracted from its seeds, is a plant anti-cancer rookie. In recent years, scientists have elucidated its structure. The past was limited to animal experiments and has not been clinically well-developed. However, the results of clinical trials in recent years have been very encouraging. It is toxic to cells, and the early stage of poisoned cells is mainly the inhibition of protein synthesis, and then the synthesis of DNA is reduced, and the final RNA synthesis is inhibited. The rate of inhibition of different protein synthesis is different, with the most rapid inhibition of myeloma protein synthesis.
