自从植物细胞有可能在培养基上生长以来,就有指望形成其次级代谢物——特殊的药物。植物来源的药物或中间体单在美国市场每年约占九十亿美元,如吗啡、可待因、士的宁、马钱子碱、洋地黄毒甙等。植物细胞混悬培养比整体植物生长快,容易控制营养及环境的需要,可以整年生产药物,不受地理、政治、社会及价格浮动的影响。此外,细胞培养能生产出有更大生理活性的新化合物。
Since plant cells have the potential to grow on culture media, there is hope to form their secondary metabolites—special drugs. Plant-derived drugs or intermediates alone account for approximately US$9 billion annually in the U.S. market, such as morphine, codeine, strychnine, brucine, and digoxigenin. The suspension culture of plant cells is faster than the growth of the whole plant, and it is easy to control the needs of nutrition and the environment. It can produce drugs throughout the year, regardless of geographical, political, social and price fluctuations. In addition, cell cultures can produce new compounds with greater physiological activity.
